1 REGULATORY AND SAFETY INFORMATION

1.1 SAFETY SYMBOL CONVENTIONS

The following conventions are used in this manual to alert the user to general safety precautions that must

be observed during all phases of operation, installation, service, and repair of this product. Failure to

comply with these precautions or with specific warnings elsewhere violates safety standards of design,

manufacture, and intended use of the product. Harris Corporation assumes no liability for the customer's

failure to comply with these standards.

WARNING

The WARNING symbol calls attention to a procedure, practice, or the like, which,

if not correctly performed or adhered to, could result in personal injury. Do not

proceed beyond a WARNING symbol until the conditions identified are fully

understood or met.

CAUTION

The CAUTION symbol calls attention to an operating procedure, practice, or the like,

which, if not performed correctly or adhered to, could result in damage to the

equipment or severely degrade equipment performance.

NOTE

The NOTE symbol calls attention to supplemental information, which may improve

system performance or clarify a process or procedure.

1.2 RF ENERGY EXPOSURE AWARENESS AND CONTROL

INFORMATION FOR FCC OCCUPATIONAL USE REQUIREMENTS

Before using the two-way mobile radio, review the following important RF energy awareness and

control information and operational instructions. Comply with this information and instructions in

order to ensure compliance with RF exposure guidelines.

This radio is intended for use in occupational/controlled conditions, where users

have full knowledge of their exposure and can exercise control over their

exposure to remain below RF exposure limits. This radio is NOT authorized for

general population, consumer, or any other use.

Changes or modifications not expressly approved by Harris

could void the user's

authority to operate the equipment.

This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide

communications between two or more users over a distance. It uses RF energy or radio waves to send and

receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited

to, electric power, sunlight, and x-rays. RF energy, however, should not be confused with these other

forms of electromagnetic energy, which, when used improperly, can cause biological damage. Very high

levels of x-rays, for example, can damage tissues and genetic material.

Experts in science, engineering, medicine, health, and industry work with organizations to develop

standards for exposure to RF energy. These standards provide recommended levels of RF exposure for

WARNING

CAUTION

MM-012137-001, Rev. J

both workers and the general public. These recommended RF exposure levels include substantial margins

of protection. All two-way radios marketed in North America are designed, manufactured, and tested to

ensure they meet government-established RF exposure levels. In addition, manufacturers also recommend

specific operating instructions to users of two-way radios. These instructions are important because they

inform users about RF energy exposure and provide simple procedures on how to control it. Refer to the

following websites for more information on what RF energy exposure is and how to control exposure to

assure compliance with established RF exposure limits:

http://www.fcc.gov/oet/rfsafety/rf-faqs.html

http://www.osha.gov./SLTC/radiofrequencyradiation/index.html

1.2.1 Federal Communications Commission Regulations

Before it was marketed in the United States, the M5300 two-way mobile radio was tested to ensure

compliance with FCC RF energy exposure limits for two-way mobile radios. When two-way radios are

used as a consequence of employment, the FCC requires users to be fully aware of and able to control

their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a

label directing users to specific user awareness information. The radio has an RF exposure product label.

Also, this Installation and Product Safety Manual and the applicable Operator’s Manual include

information and operating instructions required to control RF exposure and to satisfy compliance

requirements.

1.3 COMPLIANCE WITH RF EXPOSURE STANDARDS

The M5300 two-way mobile radio is designed and tested to comply with a number of national and

international standards and guidelines regarding human exposure to RF electromagnetic energy. This

radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure

environment at duty-cycle times of up to 50% (50% transmit, 50% receive), and it is authorized by the

FCC for occupational use. In terms of measuring RF energy for compliance with the FCC exposure

guidelines, the radio’s antenna radiates measurable RF energy only while it is transmitting (talking), not

when it is receiving (listening), or in a standby mode.

The M5300 two-way mobile radio complies with the following RF energy exposure standards and

guidelines:

• United States Federal Communications Commission (FCC), Code of Federal Regulations; 47 CFR

§ 2 sub-part J.

• American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE)

C95.1-2005.

• Institute of Electrical and Electronic Engineers (IEEE) C95.1-2005.

• IC Standard RSS-102, Issue 2, 2005: Spectrum Management and Telecommunications Radio

Standards Specification. Radiofrequency Exposure Compliance of Radiocommunication Apparatus

(All Frequency Bands).

The following tables list the recommended minimum safe lateral distances for

controlled environments and for unaware bystanders in uncontrolled environments,

from transmitting antennas (i.e., monopoles over a ground plane, or dipoles) at rated

radio power for mobile radios installed in a vehicle. See Table 1-1 for 800 MHz

M5300 mobile radios. See Table 1-2 for 900 MHz M5300 mobile radios. Transmit

only when unaware bystanders are at least the uncontrolled recommended minimum

safe lateral distance away from the radio’s transmitting antenna.

50% duty cycle.

1.3.1 Mobile Antennas

Antenna(s) for the mobile radio must be installed in accordance with Section 6 of this manual. Installation

guidelines presented in Section 6 are limited to metal-body motor vehicles or vehicles with appropriate

ground planes.

Use only approved/supplied antenna(s) or an approved replacement antenna. Unauthorized antennas,

modifications, or attachments can cause the FCC RF exposure limits to be exceeded.

1.3.2 Approved Accessories

The radio has been tested and meets FCC RF guidelines when used with accessories supplied or

designated for use with it. Use of other accessories may not ensure compliance with the FCC’s RF

exposure guidelines, and may violate FCC regulations. For a list of approved accessories refer to Section

4 in this manual (begins on page 25) and/or the Products and Services Catalog.

MM-012137-001, Rev. J

1.3.3 Contact Information

For additional information on RF exposure and other information, contact Harris using one of the contact

links listed in Section 3.4 on page 24.

1.4 OCCUPATIONAL SAFETY GUIDELINES AND SAFETY TRAINING

INFORMATION

To ensure bodily exposure to RF electromagnetic energy is within the FCC allowable limits for

occupational use. Always adhere to the following basic guidelines:

• The push-to-talk button should only be depressed when intending to send a voice message.

• The radio should only be used for necessary work-related communications.

• The radio should only be used by authorized and trained personnel. It should never be operated by

children.

• Do not attempt any unauthorized modification to the radio. Changes or modifications to the radio may

cause harmful interference and/or cause it to exceed FCC RF exposure limits. Only qualified

personnel should service the radio.

• Always use only authorized accessories (antennas, control heads, speakers/mics, etc.). Use of

unauthorized accessories can cause the FCC RF exposure compliance requirements to be exceeded.

The information listed above provides the user with information needed to make him or her aware of a RF

exposure, and what to do to assure that this radio operates within the FCC exposure limits of this radio.

1.5 COMMON HAZARDS

The operator of any mobile radio should be aware of certain hazards common to

the operation of vehicular radio transmissions. Possible hazards include but are

not limited to:

• Explosive Atmospheres — Just as it is dangerous to fuel a vehicle while its engine is running, be

sure to turn the radio OFF while fueling the vehicle. If the radio is mounted in the trunk of the

vehicle, DO NOT carry containers of fuel in the trunk.

Areas with potentially explosive atmosphere are often, but not always, clearly marked. Turn the radio

OFF when in any area with a potentially explosive atmosphere. It is rare, but not impossible that the

radio or its accessories could generate sparks.

• Interference To Vehicular Electronic Systems — Electronic fuel injection systems, electronic anti-

skid braking systems, electronic cruise control systems, etc., are typical of the types of electronic

devices that can malfunction due to the lack of protection from radio frequency (RF) energy present

when transmitting. If the vehicle contains such equipment, consult the dealer for the make of vehicle

and enlist his aid in determining if such electronic circuits perform normally when the radio is

transmitting.

• Electric Blasting Caps — To prevent accidental detonation of electric blasting caps, DO NOT use

two-way radios within 1000 feet (305 meters) of blasting operations. Always obey the “Turn Off

Two-Way Radios” (or equivalent) signs posted where electric blasting caps are being used. (OSHA

Standard: 1926.900).

• Radio Frequency Energy — To prevent burns or related physical injury from radio frequency

energy, do not operate the transmitter when anyone outside of the vehicle is within the minimum safe

WARNING

MM-012137-001, Rev. J

distance from the antenna as specified in Table 1-1 (for 800 MHz mobile radios) or in Table 1-2 (for

900 MHz mobile radios). Refer to Section 1.2 for additional information.

• Vehicles Powered By Liquefied Petroleum (LP) Gas — Radio installation in vehicles powered by

liquefied petroleum gas, where the LP gas container is located in the trunk or other sealed-off space

within the interior of the vehicle, must conform to the National Fire Protection Association standard

NFPA 58. This requires:

 The space containing the radio equipment must be isolated by a seal from the space containing

the LP gas container and its fittings.

 Outside filling connections must be used for the LP gas container.

 The LP gas container space shall be vented to the outside of the vehicle.

• Vehicles Equipped with Airbags — For driver and passenger safety, avoid mounting the radio’s

control head (or any other component) above or near airbag deployment areas. In addition to driver-

side and passenger-side front-impact airbags, some vehicles may also be equipped with side-impact

airbags. For occupant safety, verify the location of all airbags within the vehicle before installing the

radio equipment.

1.6 SAFE DRIVING RECOMMENDATIONS

The American Automobile Association (AAA) advocates the following key safe driving recommenda-

tions:

• Read the literature on the safe operation of the radio.

• Keep both hands on the steering wheel and the microphone in its hanger whenever the vehicle is in

motion.

• Place calls only when the vehicle is stopped.

• When talking from a moving vehicle is unavoidable, drive in the slower lane. Keep conversations

brief.

• If a conversation requires taking notes or complex thought, stop the vehicle in a safe place and

continue the call.

• Whenever using a mobile radio, exercise caution.

1.7 OPERATING RULES AND REGULATIONS

Two-way radio systems must be operated in accordance with the rules and regulations of the local,

regional, or national government.

In the United States, the M5300 mobile radio must be operated in accordance with the rules and

regulations of the Federal Communications Commission (FCC). Operators of two-way radio equipment

must be thoroughly familiar with the rules that apply to the particular type of radio operation. Following

these rules helps eliminate confusion, assures the most efficient use of the existing radio channels, and

results in a smoothly functioning radio network.

When using a two-way radio, remember these rules:

• It is a violation of FCC rules to interrupt any distress or emergency message. The radio operates in

much the same way as a telephone “party line.” Therefore, always listen to make sure the channel is

clear before transmitting. Emergency calls have priority over all other messages. If someone is

sending an emergency message – such as reporting a fire or asking for help in an accident, do not

transmit unless assistance can be offered.

MM-012137-001, Rev. J

• The use of profane or obscene language is prohibited by Federal law.

• It is against the law to send false call letters or false distress or emergency messages. The FCC

requires keeping conversations brief and confined to business. Use coded messages whenever

possible to save time.

• Using the radio to send personal messages (except in an emergency) is a violation of FCC rules. Send

only essential messages.

• It is against Federal law to repeat or otherwise make known anything overheard on the radio.

Conversations between others sharing the channel must be regarded as confidential.

• The FCC requires self-identification at certain specific times by means of call letters. Refer to the

rules that apply to the particular type of operation for the proper procedure.

• No changes or adjustments shall be made to the equipment except by an authorized or certified

electronics technician.

Under U.S. law, operation of an unlicensed radio transmitter within the jurisdiction of

the United States may be punishable by a fine of up to $10,000, imprisonment for up to

two (2) years, or both.

1.8 OPERATING TIPS

The following conditions tend to reduce the effective range of two-way radios and should be avoided

whenever possible:

• Operating the radio in areas of low terrain, or while under power lines or bridges.

• Obstructions such as mountains and buildings.

In areas where transmission or reception is poor, communication improvement may

sometimes be obtained by moving a few yards in another direction, or moving to a

higher elevation.

3 INTRODUCTION

This manual contains installation procedures for the M5300 mobile radio, the CH-721 control heads, and

the HHC-731 hand-held controller. Procedures cover the mounting and cabling of the equipment, as well

as the basic in-vehicle test procedures. In addition, product safety-related information is included.

3.1 GENERAL DESCRIPTION

The M5300 mobile radio is a high-performance digital mobile radio. It is available in an 800 MHz version

and a 900 MHz version, and in either a front-mount or a remote-mount configuration. Shown in Figure

5-3 on page 38, the M5300 radio provides standard and advanced mobile radio communication functions.

RF operating bands of the 800 MHz M5300 mobile radio include the 806 to 824 MHz repeater input band

(mobile transmit) and the 851 to 869 MHz band used for repeater output and talk-around

communications.

RF operating bands of the 900 MHz M5300 mobile radio include the 896 to 901 MHz repeater input band

(mobile transmit) and the 935 to 940 MHz band used for repeater output and talk-around

communications.

The M5300 mobile radio supports the follow radio systems/standards:

• OpenSky® trunked radio networks using the OpenSky Trunking Protocol (OTP);

• APCO Project 25 Phase I compliant Common Air Interface (P25 CAI) trunked radio networks;

• Talk-around communications in accordance with the APCO Project 25 Phase I standard;

• Enhanced Digital Access Communications System (EDACS®) trunked radio networks;

• ProVoice™ trunked radio networks; and,

• Conventional FM repeater-based and FM talk-around voice communications in accordance with the

TIA/EIA-603 conventional land-mobile radio standard.

The M5300 is designed to operate in a mobile environment, typically within a motor vehicle. It must be

connected to an external transmit/receive antenna such as one mounted to the vehicle’s rooftop or trunk

lid. Several different types of external-mount antennas are approved and available for use with the radio,

as listed in Table 1-1 for 800 MHz radios, and in Table 1-2 for 900 MHz radios. The 800 MHz radio’s RF

transmit output power is rated at 30 watts maximum when operating in OpenSky mode, and 35 watts

maximum when operating in P25, EDACS, or conventional mode. The 900 MHz radio’s RF transmit

output power is rated at 30 watts maximum in all operating modes. Refer to Section 2 for additional

specifications.

As previously stated, front-mount and remote-mount M5300 radio configurations are available. In the

front-mount configuration, the control head is an integral part of the mobile radio. In the remote-mount

configuration, the control head is located near the radio operator’s position and the radio is mounted

remotely from the control head, typically in the vehicle’s trunk. As described later in this section, an

HHC-731 hand-held controller can be connected to a remote-mount radio, in place of the CH-721 control

head. The remote-mount radio is shown in Figure 5-3 on page 38.

Control heads used with the M5300 radio include the CH-721 Scan and the CH-721 System model

control heads. See Figure 8-5 (page 70) through Figure 8-7 (page 71). Both heads feature a large 3-line

graphical vacuum-fluorescent display, front panel controls and buttons/keys for user control of the mobile

radio, an internal high-power audio amplifier to drive an externally-connected speaker, and a front panel

microphone connector. The CH-721 System control head also has a 12-button numeric keypad that

provides Dual-Tone Multi-Frequency (DTMF) functionality and easier operator system/group selection

control at the control head’s front panel.

MM-012137-001, Rev. J

In a remote-mount M5300 mobile radio installation, the HHC-731 hand-held controller can be used in

place of the CH-721 control head. This easy-to-use hand-held mobile radio controller is primarily

designed for use in harsh environments such as maritime (i.e., boating) applications and All-Terrain

Vehicle (ATV) applications. The HHC-731 hand-held controller has easy-to-use buttons, a tough liquid-

crystal display (LCD), and a built-in microphone. As of the publication of this manual, only one (1)

HHC-731 hand-held controller can be connected to a radio, and without any connected CH-721 control

heads. The front of the HHC-731 hand-held controller is shown in Figure 8-14 on page 80.

The remote-mount M5300 radio is designed for remote mounting in a motor vehicle’s trunk, or some

other preferably unoccupied section in a vehicle, such as a fire truck’s equipment shelf. Up to four (4)

control heads can be connected to a front-mount M5300, and up to five (5) control heads can be

connected to a remote-mount M5300. The radio is remotely controlled by a control head(s) connected to

it via 3-wire Controller Area Network (CAN) cables. Between the radio and control head(s), the CAN

link carries digitized microphone and speaker audio, controlling data such as button presses and radio

messages, and user data such as that for a mobile data terminal connected to the serial port of the radio or

control head. For proper operation, the CAN link must be terminated appropriately on each end. In

multiple control head installations, two or more control heads are interconnected to the mobile radio in a

series (“daisy-chain”) fashion via CAN link cables.

As shown in Figure 8-7 on page 71, the CH-721 Scan and System model control heads used in remote-

mount radio installations have several connectors located on the head’s rear panel. These connectors

include a DC power connector, two (2) CAN port connectors used for CAN link interconnections, an

external speaker connector, a 9-pin serial port connector for connecting optional equipment such as a

mobile data terminal, and a 25-pin accessory connector. Both CH-721 models can interface to an optional

Federal Signal Electronic siren/light control system for broadcasting via a public address (PA) speaker.

The radio and control head/hand-held controller must be powered by an external +13.6-volt (nominal) DC

power source. In mobile applications, the motor vehicle’s electrical system is utilized as the source of DC

power. In a remote-mount radio installation, the CH-721 control head(s) or the HHC-731 hand-held

controller connected to the radio is also powered by the same DC power source, but separately fused.

When the control head/hand-held controller is powered-up by the operator, it “wakes up” the radio by

transmitting data to the radio via the CAN link.

The radio provides half-duplex voice and data communications. Voice communications are accomplished

via a “push-to-talk” (PTT) type microphone and an external speaker connected to the control head. The

HHC-731 hand-held controller has an integrated microphone and PTT button/key. When a control head is

employed in a mobile radio installation, an audio amplifier in the head drives the speaker. When the hand-

held controller is employed, an audio amplifier in the remote-mounted mobile radio drives the speaker.

For data communications, the radio has an industry-standard 9-pin serial interface port for connecting

optional data-type equipment, such as a Mobile Data Terminal (MDT), a laptop PC, an external display,

or a key-entry device. This port works seamlessly with equipment from popular manufacturers and off-

the-shelf applications. OpenSky employs User Datagram Protocol over Internet Protocol (UDP/IP) data

packet transfers, providing “plug and play” connectivity for data-type devices.

An optional built-in Global Positioning System (GPS) tracking receiver is available for the radio. On an

OpenSky trunked radio network, the GPS tracking receiver can provide quick and accurate unit location

information to dispatchers via the radio network. The GPS receiver determines the unit’s location and the

radio transmits it to the network, either when polled by the network or automatically on a predetermined

periodic basis. The GPS antenna can be integrated into the mobile transmit/receive antenna (i.e., a

“combination” antenna). Alternately, the GPS antenna can be located/mounted completely separate from

the mobile transmit/receive antenna.

MM-012137-001, Rev. J

The M5300 mobile radio, the CH-721 control head and the HHC-731 hand-held controller exceed tough

environmental specifications included within military standard MIL-STD-810F, the radio industry

standard TIA/EIA-603, and the radio standard established by the U.S. Forest Service.

An M5300 radio operating on an OpenSky radio network uses Time-Division Multiple-Access (TDMA)

digital modulation technology on the radio frequency link. TDMA allows multiple radio users to share a

single RF channel. In addition, a single RF channel can support simultaneous digital voice and data

communications.

OpenSky employs Advanced Multi-Band Excitation (AMBE®) speech and data compression technology

developed by Digital Voice Systems, Inc. When operating on an OpenSky radio network, AMBE gives

an M5300 the ability to provide exceptional voice quality via the limited bandwidth of the radio

frequency path, even when the received RF signal is weak (i.e., even in “fringe” areas). AMBE is

performed by a Digital Signal Processor (DSP) integrated circuit within the radio programmed to perform

an AMBE compression algorithm during mobile transmissions, and an AMBE expansion algorithm

during mobile reception.

Speech compression electronic circuitry—be it AMBE or another type such as IMBE®—is sometimes

referred to as “vocoding” circuitry for voice coding, or simply a “vocoder” circuit.

The M5300 mobile radio supports operation on APCO Project 25 phase I compliant Common Air

Interface (P25 CAI) trunked radio networks, and operation in a talk-around mode in accordance with the

APCO Project 25 phase I standard. P25 radio systems utilize Improved Multi-Band Excitation (IMBE)

speech and data compression technology, also developed by Digital Voice Systems, Inc.

Like AMBE technology, IMBE technology allows the M5300 to deliver exceptional voice quality, even

in areas where the received RF signal strength is weak. IMBE replicates human speech better than other

voice compression technologies, resulting in better voice quality and better speaker recognition. The

Telecommunications Industry Association (TIA) funded an independent study to evaluate compression

technologies. The findings showed that when compared with other industry-recognized compression

technologies, IMBE provided the highest voice quality. In the study, radio users were asked to listen to

coded speech produced by four different compression technologies (i.e., vocoder circuits) operating under

a variety of conditions. The users rated the speech on a scale of one to five, with five being the best

quality. Under each operating conditions, IMBE was rated the best.

The M5300 mobile radio can also operate using Harris’ digital voice technology called ProVoice. Like

P25 radio systems, ProVoice also employs IMBE technology.

EDACS and ProVoice trunked radio networks employ analog FM and 2-level Gaussian Frequency-Shift

Keying (GFSK) modulation techniques on the RF channels. Data is transmitted on an RF channel at a

9600 bits-per-second rate.

For over-the-air secure radio communications, the M5300 mobile radio may be equipped for 64-bit DES

(Data Encryption Standard) encryption or 128/256-bit AES (Advanced Encryption Standard) encryption.

With encryption, voice and/or user data signals transmitted and received by the radio on an RF channel

are digitally encrypted (“scrambled”) to virtually eliminate unauthorized monitoring via the RF channel.

5.3 LOCATING COMPONENTS

Plan the mounting locations of all components (radio, control head/hand-held controller, antenna, and

cables) and determine the routes for all wiring and cables. Particularly consider the connection of the

radio for planning purposes.

• Determine the customer’s preferences, if any, for location of components. Comply with these

preferences as long as they are consistent with safety recommendations and guidelines presented in

this manual, and other generally accepted professional radio installation practices.

• For a front-mount installation, the radio is typically located under the vehicle’s dash panel. However,

it may be mounted above the dash, or at some other location per customer requirements, available

space, and/or mounting surface strength. Dimensions of the radio, control head, and hand-held

controller are listed in Section 2.1 on page 18. As noted in that section, these dimensions do not

include space required at the rear of the radio for cables. Several inches of clearance space is required.

• For a remote-mount radio installation, the radio is typically located in the motor vehicle’s trunk, or

some other preferably unoccupied section in a vehicle, such as a fire truck’s equipment shelf. The

control head is typically located under the vehicle’s dash panel. Dimensions for the radio, control

head, and hand-held controller are listed in Section 2.1 on page 18. As noted in that section, these

dimensions do not include space required at the rear of the radio and control head for cables. Several

inches of clearance space is required at the back of the control head, and at least six (6) inches is

recommended at the back of the radio. In addition, several inches of clearance space is required at

each side of the radio for access to the screws that secure the radio to its mounting bracket.

• When selecting a mounting location, verify sufficient clearance behind the radio can be maintained so

cables will not be stressed, crushed, twisted, or bent at severe angles. This also applies to the control

head in a remote-mount radio installation. Also, the front and sides of the units must have clearance

for air circulation, access to mounting screws, mounting hardware, etc.

• Verify the drilling of holes and the insertion of screws will not damage or interfere with any existing

vehicle components (for example, a fuel tank, fuel lines, the transmission housing, etc.), or any

existing vehicle wiring.

• For antenna location and installation-related information, refer to Section 6.

The radio must be kept out of direct sunlight and away from heat sources. Adequate

free-air

ventilation must be provided to its rear fins. The radio will automatically

reduce its transmit

RF output power when its ambient temperature exceeds

approximately +140° Fahrenheit (+60° Celsius).

All cables should have a service loop near each connector end. Do not bend the cables

at severe angles near the connector end. Above all, after all components are installed,

verify no cable is under any tension. Failure to do so may lead to damaged cables,

causing intermittent radio operation or complete radio failure.

CAUTION

6 ANTENNA INSTALLATION

6.1 ANTENNA MOUNTING LOCATIONS

At this time, review all information presented in the

REGULATORY AND

SAFETY INFORMATION section of this manual (page 7). A transmitting antenna

must be installed in accordance with the guidelines presented in the

REGULATORY AND SAFETY INFORMATION section, and in this section. In

order to reduce human exposure to radio frequency (RF) electromagnetic energy

during transmit mode, use Figure 6-1 (for an 800 MHz radio) or Figure 6-2 (for a

900 MHz radio) a

s a guide for determining the best possible mounting

configuration/location. Also re

fer to the recommended minimum lateral safe

distances from a transmitting antenna listed in Table 1-1 (on page 9) for 800 MHz

M5300 mobile radios, and in Table 1-2 (on page 12) for 900 MHz M5300 mobile

radios.

Antennas must be mounted in one of four (4) possible locations on the vehicle. Figure 6-1 (for an 800

MHz radio) and Figure 6-2 (for a 900 MHz radio) show the recommended locations and antenna part

numbers. Also, see Table 4-8 for additional information. Always follow the antenna manufacturer’s

instructions when mounting an antenna.

6.1.1 Direct Center or Center-Rear of Rooftop

The center of the vehicle’s roof is the best location for a rooftop-mount antenna (location  in Figure 6-1

and Figure 6-2). For optimal performance, the mounting area under the antenna must be a flat with a

minimum radius of six (6) inches of metal ground plane. It must be located directly in the center of the

roof to minimize human exposure to RF electromagnetic energy. Other obstructions such as a light bar or

another antenna may prevent the antenna from being mounted in the direct center of the roof. In this case,

the antenna should be mounted a minimum of one foot away from and behind the obstruction but in the

middle of the roof with respect to the left and right sides of the vehicle (location  in Figure 6-1 and

Figure 6-2).

6.1.2 Center of Trunk Lid

Certain vehicles do not allow for the antenna to be placed in the center or center-rear of the roof. In this

case, the next best location for the antenna is in the direct center of the trunk lid (location  in Figure 6-1

and Figure 6-2). In this case, an elevated-feed-point antenna is recommended. Although this type of

antenna does not require a metal ground plane, it must be located directly in the center of the trunk lid to

minimize human exposure to RF electromagnetic energy.

6.1.3 Rear Deck Lid for Stand-Alone GPS Receive Antenna

If the M5300 mobile radio does not use a GPS combination-type antenna and it is equipped with a GPS

receiver, a stand-alone GPS receive antenna must be separately located and mounted. The vehicle’s rear

deck lid (location  in Figure 6-1 and Figure 6-2) is the recommended mounting location for this case.

This locates the GPS antenna inside the vehicle.

6.2 ANTENNA INSTALLATION PROCEDURES

An antenna must be installed before completing the radio installation.

As presented in the previous section, various antenna mounting locations exist. Optimal performance is

achieved via a rooftop antenna mounted in the direct center of the motor vehicle’s roof. Table 4-8 which

begins on page 32, along with Figure 6-1 (for 800 MHz) and Figure 6-2 (for 900 MHz) lists available

antennas.

6.2.1 Installing NMO Antenna Mounts AN-125001-001, -002, -003 and -004

These NMO style antenna mounts can each be used with several different antenna elements. Only limited

access under the mounting location is typically required. The installation procedure is presented in

Section 6.2.1.3.

6.2.1.1 Standard NMO Antenna Mounts AN-125001-001 and AN-125001-002

These standard ¾-inch NMO antenna mounts require a ¾-inch hole in a relatively flat area of the vehicle

body, with a vehicle metal thickness of between 0.020 and 0.040 inches. AN-125001-002 has a very-low-

loss coax cable (LMR-195 or equivalent).

6.2.1.2 Thick-Roof NMO Antenna Mounts AN-125001-003 and AN-125001-004

Both of these thick-roof NMO antenna mounts use either a ⅜-inch or a ¾-inch mounting hole in a

relatively flat area of the vehicle body, with a vehicle metal thickness of between 0.040 and 0.1875 inches

(3/16-inch maximum thickness). AN-125001-004 has a very-low-loss coax cable (LMR-195 or equivalent).

For thick-roof NMO antenna mounts AN-125001-003 or AN-125001-004, using a

⅜-inch mounting hole will require better

access to the underside of the mounting

location than if a ¾-inch hole is used. This is because, in the case of a ⅜-inch hole, the

antenna mount’s bushing assembly must be insert

ed from the underside of the

mounting surface.

When using a ¾-inch mounting hole to mount thick-roof NMO

antenna mounts

AN-125001-003 or AN-125001-004, the thickness of the mounting surface must be at

least ⅛-inch (0.125-inch minimum thickness). This requirement is due to the thickness

of the alignment ring used to center the bushing assembly within the ¾-inch mounting

hole.

6.2.1.3 Installation Procedure for Mounts AN-125001-001 through -004

1. Select the antenna mounting location in accordance with the information presented in Sections 1 and

6.1 of this manual. If necessary, contact the Technical Assistance Center for assistance. See page 24

for TAC contact information.

2. Verify no obstructions exist immediately below the respective mounting location on the underside of

the vehicle body, such as vehicle ribbing/body framing, a wiring harness, air bag equipment, etc. Also

verify there is a sufficient access path and clearance for the mount’s coax cable. If there is an

obstruction or insufficient clearance, select another nearby mounting location.

3. Measure and mark the center point of the selected antenna mounting location. Be sure to center the

mark from side-to-side of the vehicle.

4. Obtain a hole saw specifically designed for drilling NMO mounting holes of the required diameter.

(e.g., Antenex/Laird Technologies model HS34 or equivalent for a ¾-inch hole; Antenex/Laird

Technologies model HS38 or equivalent for a ⅜-inch hole).

5. If the vehicle’s headliner panel, carpet, seats, or otherwise, is below the mounting location, move or

remove the headliner panel, etc. as necessary to protect it. Alternately, apply a heat-resistant mask

material (such as a fiberglass mat or thin sheet metal with masked edges) as required to “catch” the

metal shavings and the metal plug (if any) produced by the hole saw. The plug (if any) may be

relatively hot if/when it drops out of the saw upon completion of the hole drilling process. ⅜-inch

diameter hole saws generally produce only shavings, not plugs.

6. With the hole saw and a drill, drill a hole at the marked hole center point. Position the drill square

with (i.e., 90 degrees from) the vehicle mounting surface so paint immediately outside of the

perimeter of the hole is evenly removed.

Excessive use of the hole saw and/or failure to position the drill square with (i.e.,

at a 90 degree angle from)

the vehicle mounting surface may result in damage to

the metal mounting surface, in the area immediately outside of the perimeter of

the hole.

7. Ensure the saw removed the paint immediately around the hole as the drilling operation completes. If

not, do so by reinserting the saw completely into the hole and spinning it as required. This allows

proper grounding via the mount’s lock nut on the top of the mounting surface. On the bottom of the

NOTE

CAUTION

MM-012137-001, Rev. J

mounting surface, the “teeth” of the mount’s bushing assembly may not provide a good ground due to

thick vehicle undercoating, thick primer, oxidation/rust, etc.

8. For a ¾-inch hole, feed the unterminated end of the mount’s coax cable into the hole from the top

surface of the vehicle until the mount’s bushing assembly is in position to drop into the hole. The

bushing should be tilted at a slight angle and fed into the hole. The threaded shank of the mount’s

bushing assembly will not fall through a ¾-inch hole.

For a ⅜-inch hole, feed the threaded shank of the mount’s bushing assembly into the hole from the

underside of the mounting surface. Hold it into position until the lock nut is installed.

9. If installing a thick-roof antenna mount (⅜-inch shank) into a ¾-inch hole, place the alignment ring

onto the threaded shank of the mount. This ring has an approximate ¾-inch outside diameter.

10. A tube of synthetic lubricant is included with the antenna mount. Apply this lubricant to the mount’s

rubber O-ring. Do not get any lubricant on the center contact of the mount’s bushing assembly.

11. As illustrated in Figure 6-3 and Figure 6-4, add the O-ring (C) and lock nut (D) to the top of the

mount’s bushing assembly (A). With the O-ring in the groove in the underside of the lock nut, thread

the lock nut onto the bushing assembly. Be sure the O-ring remains in the groove before tightening

the lock nut.

12. Using a 15/16-inch open-end wrench, tighten the lock nut until it fully compresses the O-ring and

makes good contact with the vehicle mounting surface. The groove’s ridges on the bottom of the lock

nut must make full contact with the unpainted metal surface of the vehicle.

13. Install the antenna element per the procedure in Section 6.2.4.

6.2.2 Installing NMO Magnetic Antenna Mount AN-125001-008

1. Thoroughly clean the bottom of the magnetic mount and the selected vehicle mounting surface by

removing all dust, dirt, etc.

2. Carefully place the magnet mount onto the metal surface of the vehicle at the selected location. The

coax cable exiting the mount’s base should be orientated towards the point at which it will enter into

the interior of the vehicle. Do not try to reposition it by sliding it on a painted metal surface.

3. Route the mount’s coax cable to the radio location, passing it by the trunk lid’s perimeter gasket, door

perimeter gasket, etc., as necessary.

4. Install the antenna element per the procedure in Section 6.2.4.

To remove a magnetic antenna mount, hold it

at the bottom of its base and tilt it at an

angle to release the magnetic attraction force. Do not pull on the mount’s coax cable.

Do not drag the mount across the mounting surface.

6.2.3 Installing All Other Antenna Mounts

For any other type of antenna mount not covered in the previous sections, such as GPS combination

antennas, install the mount in accordance with the installation instructions included with the mount.

6.2.4 Attaching NMO Antenna Elements

1. Clean the top surface of the NMO mount and the surface of the vehicle immediately around the

mount.

2. Place the gasket included with the antenna element (not pictured in Figure 6-3 or Figure 6-4) around

the mount and against the surface of the vehicle. If a lubricant or sealant was included with the

gasket, apply it to the gasket before placing the gasket.

3. Apply the antenna element to the top of the mount and tighten it in a clock-wise direction (as viewing

from the top). Use an appropriate wrench if required. Do not over-tighten.

4. Install a placard (not supplied) on the vehicle’s dash panel, in accordance with the following

CAUTION. Place the placard in plain view of the vehicle operator’s position.

5. Continue with the coax cable installation procedure presented in the next section.

Before entering any automatic vehicle (“car”) wash equipment, remove the antenna

element from the antenna mount

, and secure the element in a safe location inside the

vehicle. This will prevent the wash equipment from damaging the element and/or

mount. After exiting the wash equipment, thoroughly dry the top of the mount before

re-installing the element.

6.2.5 Installing the Coax Cable and TNC RF Connector

1. Route the coax cable from the antenna mount to the location where the mobile radio will be installed.

Remove headliner panel, interior panels, etc., as necessary. The cable must be kept out of casual

contact from persons within the vehicle. Tie and stow the cable as necessary to protect it from

possible chafing. Observe and follow this WARNING:

Antennas Having Part Numbers Beginning with AN-025167 and AN-025177, and

Antennas AN102800V1 and AN102800V2: The cables of these antennas should never

be cut to a shorter length. Instead, excess cable must be tied and stowed. This not only

prevents the antenna from radiating above its intended or configured power, but it

also allows for future re-installation considerations such as a relocation of the mobile

radio within the vehicle. Installations requiring longer cables are treated as custom

and separately specified.

All Other Antennas/Antenna Mounts:

The antenna cables of all other

antennas/antenna mounts can be cut to a length no shorter than six (6) feet

(1.83 meters), as measured from the base of the antenna mount.

(VS-AN-025167-010 Rev. A)

Figure 6-5: Crimping Instructions for TNC RF Connector

CAUTION

WARNING

MM-012137-001, Rev. J

2. Using an appropriate crimp tool, crimp the supplied TNC RF connector to the end of the antenna

cable. For crimping instructions, see Figure 6-5 or the instructions supplied with antenna mount.

3. The antenna cable is connected to the radio’s TNC receptacle-type (female) RF connector per a

procedure presented later in this manual. The cable and its TNC connector must be protected from

damage, dirt, and/or metal shavings which may be generated during the mechanical and electrical

installation of the radio. Temporarily tying the connector and cable-end within a small plastic bag is

recommended.

If the mobile radio installation includes a unity-gain antenna element, the element must

be tuned for maximum performance (i.e., minimum reflection) during the test

procedures presented in Section 14. Other antennas used with the M5300 are factory-

tuned and therefore do not require tuning in the field.

6.2.6 Install GPS Antenna (if Radio has GPS Receiver Option)

If the M5300 radio is equipped with the GPS receiver option, the GPS receiver may require connection to

an externally-mounted GPS antenna. The GPS antenna must be kept at least six (6) inches away from any

other antenna mounted on the vehicle and it must have at least six inches of surface ground plane beneath

it.

Connection to a GPS antenna is only required if the (optional) GPS receiver is installed

in the radio and if its functions will be utilized/required. For OpenSky radio system

applications, the GPS receiver can provide GPS data to either a locally-connected

computer/mobile data terminal, or over-the-air to the radio network. For

EDACS/ProVoice, P25 and conventional radio system applications, the GPS receiver

is typically only used to support a computer/mobile data terminal (MDT) running GPS

software connected to the radio via NMEA-formatted serial data link. Refer to Section

12 for additional information.

A combination (“combo”) antenna kit includes a GPS antenna built into the base of the

mobile antenna. Refer to Table 4-8 (page 32) and/or Figure 6-1 (page 42) for available

combo antennas.

The following antenna installation procedure is recommended:

1. After selecting a mounting location, refer to the antenna manufacturer’s mounting and testing

instructions for installation guidance. Install the antenna in accordance with these instructions. If

necessary, contact the Technical Assistance Center. See page 24 for TAC contact information. Do not

alter the GPS antenna cable length; tie and stow excess cable as necessary.

2. Route the cable from the antenna base to the location of where the radio will be installed. Remove

headliner panel, interior panels, etc., as necessary. The cable must be kept out of casual contact from

persons within the vehicle. Tie and stow it as necessary to protect it from possible chafing.

3. The antenna cable is connected to the radio’s SMA receptacle-type (female) RF connector per a

procedure presented later in this manual. The cable and its (male) SMA connector must be protected

from damage, dirt, and/or metal shavings which may be generated during the mechanical and

electrical installation of the radio. Temporarily tying the connector and cable-end within a small

plastic bag is recommended.

7 FRONT-MOUNT RADIO INSTALLATION

This section includes detailed instructions for mechanically installing and wiring a

front-mount M5300 mobile radio. For remote-mount M5300

mobile radio installation

procedures, refer to Section 8 which begins on page 60.

7.1 MOUNTING THE FRONT-MOUNT RADIO

The Mounting Bracket Kit for the front-mount M5300 mobile radio includes a heavy-gauge steel

U-shaped mounting bracket. The radio should be attached to a mounting surface using this bracket. The

bracket can be mounted above or below the radio. Kit contents are shown in Figure 7-2, and bracket

dimensions are shown in Figure 7-3.

Both the radio and the mounting bracket have multiple holes in both sides for adjusting the radio within

the bracket. The design allows for both front-to-rear tilting of the radio within the bracket for best viewing

angle, and a front-to-rear position offset. The radio has six (6) threaded mounting holes, three (3) per side,

and the mounting bracket has ten (10) corresponding holes, five (5) per side. The radio must be secured to

the bracket using at least four of the six M5 socket-head screws included in the Mounting Bracket Kit (2

screws per side).

Typically, the radio is front-to-rear centered within the bracket. However, it can be front-to-rear offset by

approximately 2 inches (5.1 centimeters), if required. Also, the radio can be positioned straight in the

bracket (i.e., parallel with the bottom surface of the bracket), or it can be tilted up or down at an angle of

between approximately 10 to 20 degrees. When positioned straight and centered front-to-rear within the

bracket, the radio extends approximately 2.5 inches (6.4 centimeters) from the front and rear edges of the

bracket. In the rear, additional clearance must be included for cables. The area directly at the front of the

radio must be completely clear of all objects (e.g., gear shift, other radio equipment, etc.) so the operator

can easily access and visualize the radio’s control head.

The mounting bracket must be attached to a secure metal surface that meets or exceeds the minimum

1/16-inch-thick steel sheet metal requirement in accordance with the following WARNING. For example,

it can be attached directly to the bottom of the dash if the gauge of the sheet metal is high and the surface

is firm and flat, or it can be attached to the transmission hump, etc., if a mounting wedge (not included) is

utilized. The front-mount M5300 radio weighs approximately 9.2 pounds (4.17 kilograms).

At a minimum, the mounting surface should be 16-gauge (approximately 1/16-inch

thick) steel sheet metal. Mounting to plastic or other material with low tensile and

shear strength could lead to an unsafe and/or failed mounting condition, turning

the radio and its mounting bracket into a projectile during a high-shock incident

such as a motor vehicle accident. If the selected mounting surface does not meet

the minimum 16-gauge

steel sheet metal requirement, the surface should be

reinforced with a metal backing plate (not supplied) or it should be reinforced

using some other approved mounting method.

In addition to improving safety of the installation, firm mounting also prevents

unreasonable vibration that could damage the radio, adversely affect transceiver

performance and/or cause its cable connections to loosen. An improperly mounted

M5300

radio may experience degradation in the quality of voice and data

communications.

7.1.1 Mounting Bracket Installation

The front-mount M5300 radio’s mounting bracket is included with the Front-Mount Mounting Bracket

Kit KT101533V1. Kit contents are shown in Figure 7-2. This kit is Item 1 listed in Table 4-5 (page 27).

When selecting a mounting location for the radio, verify sufficient clearance can be maintained around

the radio for installation and service access. A minimum clearance of approximately four (4) inches

(10 centimeters) is recommended at the rear, left and right sides of the radio. As previously stated, the

area directly at the front of the radio must be completely clear of objects so the operator can easily access

and visualize the radio’s control head.

As illustrated in Figure 7-3, the bracket is both left-to-right and front-to-rear symmetrical. It has eleven

(11) holes for securing it to a mounting surface. At least four (4) of these holes must be used to secure the

bracket to the mounting surface. Five 20-millimeter-long self-tapping screws are included in the

Mounting Bracket Kit for this purpose. However, some other type of hardware (not supplied) may be

used, such as #10-32 stainless-steel self-locking hardware (i.e., machine screws with washers and locking

nuts), or self-drilling screws. Self-drilling screws such as “TEK” screws do not require drilling of a pilot

hole prior to installation. Do not use common self-threading sheet metal screws because they will loosen

over time with vehicle vibrations.

The following mounting procedure is recommended:

1. Determine the best radio-to-bracket position and angle by test-fitting the radio into the mounting

bracket at the selected vehicle mounting location. Slide the radio between the sides of the bracket and

temporarily secure it to the bracket with several of the M5 socket-head screws from the bracket kit.

When positioned straight and centered front-to-rear within the bracket, the radio extends

approximately 2.5 inches (6.4 centimeters) from the front and rear edges of the bracket. In the rear,

additional clearance must be included for cables. The area directly at the front of the radio must be

completely clear of all objects (e.g., gear shift, other radio equipment, etc.) so the operator can easily

access and visualize the radio’s control head.

2. At the rear of the radio, verify sufficient clearance is available for cables and service access.

3. If the mounting surface is not flat (such as the top of a transmission hump), construct a suitable

mounting wedge as necessary, and attach the wedge to the surface using an approved attachment

method. Never mount the bracket directly to a non-flat surface.

4. On the mounting surface, mark the selected location for the bracket, and then remove the radio from

the bracket.

5. Clean and remove any foreign material from the mounting surface.

6. Using the bracket as a template, and/or the dimensional information shown in Figure 8-3, mark and

drill at least four (4) mounting holes into the mounting surface as required per the type of hardware

used.

Before drilling holes and/or installing mounting screws, verify these operations will not

damage or interfere with any existing vehicle component (the fuel tank, a fuel line, the

transmission housing, existing vehicle wiring, etc.). Always check to see how far the

mounting screws will extend below the mounting surface prior to installation. Always

deburr drilled holes before installing screws.

7. Temporarily remove the bracket and deburr all of the newly drilled holes.

8. If necessary, apply an approved paint or rust-inhibitor at the holes in the mounting surface.

9. Set the bracket back into place.

10. Install and tighten the mounting screws/hardware.

11. Verify the bracket is firmly secured to the mounting surface. A secure mount prevents unreasonable

vibration, which could damage the radio and/or cause its cable connections to loosen.

12. If the rear of the radio is easily accessible when the radio is positioned in the selected position within

the bracket, it is recommended that the radio be temporarily inserted into the bracket. Otherwise, do

not mount the radio into the bracket at this time, because several cable connections must be made at

the rear of the radio.

7.1.2 Inserting the Radio into the Mounting Bracket

The radio should now be inserted into the mounting bracket according to this procedure:

1. Lay the radio into the mounting bracket with the front of the radio facing in the correct direction

(usually towards the rear of the vehicle).

2. Secure the radio to the bracket using at least four (4) of the six (6) M5 x 10 mm stainless-steel socket-

head screws included with the Mounting Bracket Kit. These screws have captive lockwashers. Kit

contents are shown in Figure 7-2. This kit is Item 1 listed in Table 4-5 (page 27).

3. Tighten all screws using a 4-millimeter hex key wrench until each lockwasher is fully compressed

and the radio is firm and flush in between the brackets.

4. Check the mounting area for proper clearance for cable service looping and for air circulation, plus an

area to secure and rest the excess cable lengths.

Proper mounting is one factor that ensures optimal radio performance. An improperly

mounted radio may

experience degradation in the quality of voice and data

communications.

7.2 FRONT-MOUNT RADIO’S DC POWER INSTALLATION

7.2.1 Overview of On/Off Power Wiring Configurations

The following power wiring configurations are supported:

• Radio turns on and off automatically with vehicle’s ignition switch/key — This configuration

allows the on/off state of the vehicle’s ignition switch/key to control the on/off power state of the

radio. The white wire of the radio’s DC Power Cable is connected to a fused switched power source,

typically identified as vehicle “Accessory” power. This source must switch on (up to positive (+)

battery voltage potential) when the vehicle’s ignition switch/key turns on, and it must switch off (to

CAUTION

NOTE

MM-012137-001, Rev. J

near zero volts) when the ignition switch/key turns off. The required fuse rating is 3 amperes. When

using this configuration, the on/off/volume control must be left in the on position for automatic

power-up/down to function properly.

In a front-mount M5300 radio installation, to fuse the white wire of the radio’s DC

Power Cable, a yellow waterproof (HFB type) fuse holder and a 3-amp AGC fuse are

included with the cable.

• Radio turns on and off with a manual switch — This configuration is used when, for example, the

radio has to remain on even when the ignition key must be removed from the vehicle and a separate

on/off switch is acceptable. The white wire of the radio’s DC Power Cable is connected to one side of

a manually-controlled switch, and the other side of this switch is connected to unswitched and fused

vehicle power. The required fuse rating is 3 amperes. When using this configuration, the

on/off/volume control must be left in the on position for automatic power-up/down to function

properly.

• Radio turns on with its on/off/volume control (“hot wired”) — This configuration allows radio

on/off power control only via its on/off/volume control. It may be desired if, for example, the radio

has to remain on even when the ignition key must be removed from the vehicle and a separate on/off

switch is not desired and/or not acceptable. The white wire of the radio’s DC Power Cable must be

connected to unswitched and fused vehicle power. The required fuse rating is 3 amperes.

In all of the above cases, the radio’s main DC power input (red wire) must be connected through an in-

line fuse to unswitched vehicle DC power. The red wire must be connected to raw battery power (positive

battery terminal) via the supplied fuse.

Any DC input power provided to the radio shall be no higher or

lower than

13.6 volts DC ±10%. The DC input power should be free and clear of any AC noise or

DC spikes above 18 v

olts. If the vehicle cannot meet these requirements, then DC

conditioning will be required before any DC power is connected to the radio. This

includes conditioning for both the radio’s main DC power input lead and for its

switched ignition sense power input. DC conditioning can be accomplished by a noise

filter or DC isolation equipment such as Harris part number FL-018314-001 or FL-

018314-002, or similar units with equal specifications. The fuse must be placed in-line

before any noise filter. Contact TAC for additional information.

The radio’s DC Power Cable has a 3-pin connector, a 20-foot red wire (for the main power connection), a

20-foot white wire (for the switched power source connection), and a 4-foot black wire (for the ground

connection). It is supplied with waterproof fuse holders, two AGC-type fuses, and non-insulated ring

terminals. The following installation procedures are recommended:

7.2.2.1 Black Wire Connection (Ground Wire)

1. Connect the radio’s DC Power Cable to the radio by mating its 3-pin connector to the radio’s 3-pin

power cable connector as follows: Visually align the key and firmly push and turn the outer locking

ring clockwise until it stops. A click will be sensed to confirm proper mating.

2. Prepare to connect the cable’s black wire to vehicle ground by locating an area of vehicle metal

within approximately two (2) feet of the radio. This surface must have a solid and stable connection

to vehicle ground. If not, add grounding strap(s) as necessary.

NOTE

CAUTION

MM-012137-001, Rev. J

3. Strip the area of any paint or dirt to expose a bare metal surface, approximately ¾-inch square.

4. Drill a hole in the approximate center of the bare metal surface, and deburr it. A ⅜-inch non-

insulated ring terminal is supplied with the cable to make this ground connection. Therefore, hole

diameter should be appropriate for the utilized grounding screw/bolt size and type used to connect the

ring terminal to the bare metal surface. This hardware is not supplied.

5. Cut the black wire to the required length plus some additional length for a service loop, then strip

insulation back approximately ¼-inch.

6. Crimp a ⅜-inch non-insulated ring terminal (supplied with the cable) to the end of the black wire.

7. Attach the ring terminal and black wire to the bare metal surface using stainless-steel self-locking

hardware (i.e., machine screws with washers and locking nuts) or other appropriate hardware to

ensure a reliable terminal-to-metal contact. Tighten securely.

8. Apply an approved paint or rust-inhibitor over the remaining exposed bare metal surface and around

the ring terminal.

7.2.2.2 Red Wire and Main Fuse Holder Connection (Radio’s Main Power Wire)

1. Continue installation of the radio’s DC Power Cable by routing its 20-foot 10-AWG red wire to the

location of the vehicle’s battery (or its main DC bus bar or stud). Remove interior panels, door kick

panels, etc., and route the wire through existing channels in the vehicle body as necessary. Protect the

wire from possible chafing where necessary. Tie and stow the wire as necessary.

Plan the routing of the 10-AWG red wire carefully, using an existing access hole in the

vehicle’s firewall if possible. Alternately, drill a new hole approximately ½-inch in

diameter and install a small rubber grommet (one supplied with the bracket kit) to

protect the wire from chafing at the hole’s sharp metal edge. To prevent fumes from

entering the passenger compartment, this hole/grommet/wire combination must

also be sealed with a silicon-based sealer before completing the installation.

Do not install any wiring or fuse holder over or in the near vicinity of the vehicle’s

engine. Excessive engine heat can cause permanent damage to these components and

can lead to intermittent electrical connection to the battery.

Before making connections to the battery’s positive post, carefully disconnect the

battery’s negative (ground) cable(s). This will prevent tools or other metallic

objects which come in contact with the battery’s positive terminal from shorting to

vehicle ground, causing sparks or even a fire or an explosion! When disconnecting

the negative cable(s), cover/insulate the positive post(s) if it is not already so a tool

cannot short between the posts. Some vehicles, such as those with diesel engines

have more than one battery; in this case, disconnect the negative cables at all

batteries.

Radio fuses should not

be installed until all wiring is complete. This will prevent

the radio from powering up prematurely and/or causing an in-rush of current that

could lead to shorting of the battery, sparks, or even fire.

2. Obtain the orange waterproof (HFB type) fuse holder included with the DC Power Cable.

3. Observe and follow the previously presented WARNING!

CAUTION

WARNING

MM-012137-001, Rev. J

4. Cut the red wire to the required length for connection to the battery’s positive (+) battery terminal (or

the main DC bus bar or stud).

5. Prepare to splice the fuse holder into the red wire by cutting it again, at approximately three (3) to six

(6) inches from the end.

6. Strip all three (3) wire ends back approximately ⅜-inch, place a fuse holder shell on each wire, and

securely crimp a fuse holder terminal to each wire end. Before crimping, verify fuse holder shells are

oriented in the correct directions (i.e., with each large end towards the wire end).

7. Label this fuse holder and red wire appropriately (e.g., “M5300 Main Power: 15-AMP FUSE”).

8. Do NOT install a fuse into the fuse holder at this time.

9. Crimp an appropriate electrical terminal to the short red wire. A corrosion-resistant ⅜-inch ring

terminal is included with the cable for this purpose, but another size corrosion-resistant terminal type

(not supplied) may be used if required.

10. Connect the ring terminal directly to the battery’s positive post (or if present, to a stud on the battery’s

main/non-switched power distribution terminal block).

A front-mount M5300 mobile radio installation may be equipped with additional CH-721

control heads in a multi-head installation. In this case, refer to Section 8.3 (begins on page

70) for control head installation procedures.

7.2.2.3 White Wire Connection

A review of the information presented in Section 7.2.1 (page 54) may be beneficial at this time. As

required per the chosen power-up configuration, connect the white wire by following one of the three

procedures presented in the respective sub-section that follows.

7.2.2.3.1 Radio Turns On and Off with Vehicle’s Ignition Switch/Key

With this wiring configuration, the radio (and its control head) automatically turns on and off with the

vehicle’s ignition switch/key. The white wire is sometimes referred to as the “white ignition switch wire”

or the “ignition sense input wire.” In this configuration, the white wire connects to a switched power

source, typically identified as “Accessory” power, that switches on and off with the vehicle’s ignition

switch/key. When using this configuration, the CH-721 control head’s on/off/volume control must be left

in the on position for automatic power-up/down to function properly.

The white ignition sense wire must be connected to a fused power source that switches

from approximately zero volts to approximately +13.6 volts when the vehicle’s ignition

switch/key is turned from the OFF position to the ACCESSORY and RUN positions.

Use

of a switched power source that is subject to voltage changes as a result of other

actions, such as opening a vehicle door, may result in undesirable radio power cycles.

1. Locate the vehicle’s switched ignition or “Accessory” power connection point that will be used for

the switched ignition 12-volt DC power source. This point is typically located at or near the vehicle’s

fuse panel. It may be necessary to consult the vehicle manufacturer’s wiring diagram.

2. Route the white wire of the radio’s DC Power Cable from the back of the radio to the area near this

connection point. Protect the wire from possible chafing as necessary.

3. Obtain the other waterproof (HFB-type) fuse holder included with the radio’s DC Power Cable.

NOTE

MM-012137-001, Rev. J

4. Cut excess length from the white wire and splice the fuse holder into it, near the location of the

connection point.

5. Using an appropriate electrical terminal, connect the white wire to the switched power connection

point. An open-barrel spade terminal is included with the cable for this purpose, but another type of

terminal (not supplied) may be used as required.

6. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder.

7. Tie and stow all wiring as necessary so it remains out of the way of casual contact and wire chafe is

avoided.

8. Continue with the speaker installation procedures presented in Section 9.1 on page 86.

7.2.2.3.2 Radio Turns On and Off with a Manual Switch

With this wiring configuration, the radio (and its control head) is manually turned on and off via an on/off

switch mounted separately from the radio, not through the vehicle’s ignition switch/key. This

configuration is used when, for example, the radio must remain on even when the ignition key must be

removed from the vehicle and a separate on/off switch is acceptable and/or required. In this configuration,

the white wire connects to a fused switched power source such as that provided by a toggle switch

mounted on the vehicle’s dash panel. When using this configuration, the CH-721 control head’s

on/off/volume control must be left in the on position for automatic power-up/down to function properly.

1. Route the white wire of the radio’s DC Power Cable from the back of the radio to an area near the

location of the panel-mounted on/off switch. Protect the wire from possible chafing as necessary.

2. Cut a short section (6 to 8 inches) off the end of the white wire and strip the ends.

3. Obtain the other waterproof (HFB-type) fuse holder included with the radio’s DC Power Cable, and

crimp one half of it to one end of the short section of wire.

4. Using an appropriate electrical terminal, connect this short white wire to unswitched 12-volt DC

power source at or near the vehicle’s fuse box.

5. Cut another section of white wire from the cable. This wire must be long enough to reach from the

fuse holder to the location of the panel-mounted on/off switch.

6. Strip one end of this wire and crimp the other half of the waterproof fuse holder to this wire end.

7. Strip the other end of this wire and, using an appropriate electrical terminal, connect it to the common

terminal of the switch.

8. Connect the white wire of the power cable to the load (switched) side of the switch.

9. If not already, mount the switch to the vehicle’s dash panel, or other customer-selected location.

10. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder.

11. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe

is avoided.

12. Label this power switch accordingly. For example: “RADIO ON/OFF.”

13. Continue with the speaker installation procedures presented in Section 9.1 on page 86.

7.2.2.3.3 Radio Is “Hot Wired”

In the “hot-wired” configuration, the radio (and its control head) is turned on and off only by the control

head’s on/off/volume control located on the front panel of the control head. In this configuration, the

white wire must be connected to unswitched and fused 12-volt vehicle power. Follow the procedure

MM-012137-001, Rev. J

presented in Section 7.2.2.3.1, except connect the white wire to unswitched battery power instead of

switched (“Accessory”) power. Be sure to fuse this connection with the provided in-line fuse holder and

3-amp AGC fuse.

7.3 TERMINATE CAN PORTS

Add a CAN Terminator to each CAN port connector on the rear of the radio. Two (2) CAN Terminators

are included in the installation kit for this purpose (item 3 in Table 4-5).

MM-012137-001, Rev. J

8 REMOTE-MOUNT RADIO INSTALLATION

This section includes detailed instructions for mechanically installing and wiring a

remote-mount M5300 mobile radio. For front-mount M5300

mobile radio installation

procedures, refer to Section 7 which begins on page 50.

8.1 MOUNTING THE REMOTE-MOUNT RADIO

This section provides details on mounting a remote-mount M5300 mobile radio in the vehicle. CH-721

control head installation procedures are included in Section 8.3 which begins on page 70. HHC-731

hand-held controller installation procedures are included in Section 8.4 which begins on page 79.

As an assembled unit, the radio weighs approximately 8 pounds (3.63 kilograms). The preferred mounting

of the radio is on top of a firm, flat surface. Radio dimensions are shown in Figure 8-1.

Installation Kit MAHK-NZN7R (contents listed in Table 4-6 on page 28) contains the

most complete set of materials for installing the remote-mount M5300 mobile radio.

Therefore, the following instructions make repeated reference to this kit. Item numbers

given in parenthesis refer to items in the kit.

Prior to beginning the installation, verify the radio has the proper version of software

and verify it has been configured properly for customer usage. Consult with the radio

system network administration personnel as necessary.

Though generally mounted in a trunk or remote location, the remote-mount mobile

radio must be kept away from heat sources. Mounting it in a location which is out of

direct sunlight is recommended but not required. Adequate ventilation space must be

provided to the side fins. The radio reduces its RF output power when its ambient

temperature exceeds approximately +140 o Fahrenheit (+60o Celsius).

At a minimum, the mounting surface should be 16-gauge (approximately 1/16-inch

thick) steel sheet metal. Mounting to plastic or other material with low tensile and

shear strength could lead to an unsafe and/or failed mounting condition, turning

the radio and its mounting bracket into a projectile during a high-shock incident

such as a motor vehicle accident. If the selected mounting surface does not meet

the minimum 16-gauge

steel sheet metal requirement, the surface should be

reinforced with a metal backing plate (not supplied) or it should be reinforced

using some other approved mounting method.

Before drilling holes and/or installing mounting screws, verify these operations will not

damage or interfere with any existing vehicle component (the fuel tank, a fuel line, the

transmission housing, existing vehicle wiring, etc.). Always check to see how far the

mounting screws will extend below the mounting surface prior to installation. Always

deburr drilled holes before installing screws.

8.1.1 Mounting Bracket Installation

The remote-mount radio’s mounting bracket is included with the Remote-Mount Mounting Bracket Kit

KT23117. Kit contents are shown in Figure 8-2. This kit is Item 1 listed in Table 4-6 (page 28).

M5 Hardware for Mounting Bracket

Securing Radio FM103111V1

to Bracket

Figure 8-2: Remote-Mount Mounting Bracket Kit KT23117

Typically, the radio’s mounting bracket is mounted in the vehicle’s trunk, on the top surface of the trunk

tray or on the trunk floor. However, it can be suspended from the trunk’s rear deck if the surface is

completely flat and the thickness of deck’s sheet metal is adequate.

When selecting a mounting location for the radio, verify sufficient clearance can be maintained around

the radio for installation and service access. A minimum clearance of four (4) inches (approximately

10 centimeters) is recommended at the rear, left and right sides of the radio, and at least 2 inches

(approximately 5 centimeters) of clearance is recommended at the front of the radio.

As illustrated in Figure 8-3, the bracket is left-to-right symmetrical and the shortest portion of its side

rails are at the rear.

As installations differ, bracket-to-vehicle mounting screws are not included. Utilization of ¼-inch-

diameter, 28-thread-per-inch (¼-28) stainless-steel self-locking hardware (i.e., machine screws with

washers and locking nuts) is highly recommended. However, ¼-inch stainless-steel self-drilling screws

may be employed to speed installation time. Self-drilling screws such as “TEK” screws do not require

drilling of a pilot hole prior to installation. Do not use common self-threading sheet metal screws because

they will loosen over time with vehicle vibrations.

The bracket has four (4) available mounting holes. All four must be used to secure the bracket to its

mounting surface.

The following mounting procedure is recommended:

1. Using the mounting bracket as a template, and/or the dimensional information shown in Figure 8-3,

mark and drill four (4) mounting holes into the mounting surface as required per the type of hardware

used. When the radio is installed in the bracket, it will extend approximately one (1) inch past the

front edge bracket, and at the rear, it will extend approximately ½-inch past the rear edge of the

bracket. This distance at the rear does not include space required for cable connections at the rear of

the radio. As previously stated, a clearance of least four (4) inches (approximately 10 centimeters) at

the rear of the radio is recommended.

2. Temporarily remove the bracket and deburr all of the newly drilled holes.

MM-012137-001, Rev. J

3. If necessary, apply an approved paint or rust-inhibitor at the holes in the mounting surface.

4. Set the bracket back into place, and verify front-to-rear orientation.

5. Install and tighten the mounting screws/hardware.

6. Verify the bracket is firmly secured to the mounting surface. A secure mount prevents unreasonable

vibration, which could damage the radio and/or cause its cable connections to loosen.

8.1.2 Inserting the Radio into the Mounting Bracket

The radio should now be inserted into the bracket according to this procedure:

1. Lay the radio down into the mounting bracket with the front of the radio at the front of the mounting

bracket.

2. Attach the radio into the mounting bracket using the six (6) M5 x 10 mm stainless-steel hex-head

screws, and flatwashers and lockwashers included with the Mounting Bracket Kit (item 1 in Table

4-6). Tighten all six screws using a 5/16-inch wrench (or a ¼-inch-drive ratchet with a 5/16-inch socket)

until each lockwasher is fully compressed and the radio is firm and flush in between the brackets.

3. Check the mounting area for proper clearance for cable service looping and for air circulation, plus an

area to secure and stow the excess cable lengths.

Proper mounting is one factor that ensures optimal radio performance. An improperly

mounted radio m

ay experience degradation in the quality of voice and data

communications.

8.2 REMOTE-MOUNT RADIO’S DC POWER INSTALLATION

Unless otherwise noted, references in the following subsections to the “control head”

also apply to the hand-held controller.

8.2.1 Overview of On/Off Power Wiring Configurations

Radio on/off power control is accomplished by the control head, except in the case of a data-only radio

installation which has no control head. In a standard installation, when the control head is turned on, it

“wakes-up” the radio via data activity on the CAN link. The following power wiring configurations are

supported:

• Radio turns on and off automatically with vehicle’s ignition switch/key — This configuration

allows the on/off state of the vehicle’s ignition switch/key to control the on/off power state of the

radio. The white wire of the control head’s DC Power Cable is connected to a fused switched power

source, typically identified as vehicle “Accessory” power. This source must switch on (up to positive

(+) battery voltage potential) when the vehicle’s ignition switch/key turns on, and it must switch off

(to near zero volts) when the ignition switch/key turns off. The required fuse rating is 3 amperes.

When using this configuration, the CH-721 control head’s on/off/volume control must be left in the

on position for automatic power-up/down to function properly.

In a remote-mount radio installation, to fuse the white wire of the control head’s DC

Power Cable, a yellow waterproof (HFB type) fuse holder and a 3-amp AGC fuse are

included with the cable.

• Radio turns on and off with a manual switch — This configuration is used when, for example, the

radio must remain on even when the ignition key must be removed from the vehicle and a separate

on/off switch is acceptable. The white wire of the control head’s DC Power Cable is connected to one

side of a manually-controlled switch, and the other side of this switch is connected to unswitched and

fused vehicle power. The required fuse rating is 3 amperes. When using this configuration, the

CH-721 control head’s on/off/volume control must be left in the on position for automatic power-

up/down to function properly. This does not apply to the HHC-731 hand-held controller.

NOTE

MM-012137-001, Rev. J

• Radio turns on with control head’s on/off/volume control (“hot wired”) — This configuration

allows radio on/off power control only via the control head’s on/off/volume control. It may be desired

if, for example, the radio must remain on even when the ignition key must be removed from the

vehicle and a separate on/off switch is not desired and/or not acceptable. The white wire of the

control head’s DC Power Cable must be connected to unswitched and fused vehicle power. The

required fuse rating is 3 amperes.

In all of the above cases, both the radio’s main DC power input (red wire) and the control head’s main

DC power input (also a red wire) must each be connected through an in-line fuse to unswitched vehicle

DC power. The red wire of the radio’s DC Power Cable must be connected to raw battery power (positive

battery terminal) via the supplied fuse. Likewise, the red wire of the control head’s DC Power Cable must

also be connected to unswitched vehicle DC power via another supplied fuse. The white ignition wire of

the radio’s DC Power Cable is only used for the data-only radio (i.e., no control head), and it is the only

means for turning its power on in the data-only radio installation.

Any DC input power

provided to the radio shall be no higher or lower than

13.6 volts DC ±10%. The DC input power should be free and clear of any AC noise or

DC spikes above 18 v

olts. If the vehicle cannot meet these requirements, then DC

conditioning will be required before any DC power is connected to the radio. This

includes conditioning for both the radio’s main DC power input lead and for its

switched ignition sense power input. DC conditioning can be accomplished by a noise

filter or DC isolation equipment such as Harris part number FL-018314-001 or FL-

018314-002, or similar units with equal specifications. The fuse must be placed in-line

before any noise filter. Contact TAC for additional information.

8.2.2 DC Power Cable and Main Fuse Holder Installation

The radio’s DC Power Cable has a 3-pin connector, a 20-foot red wire (for the main power connection), a

20-foot white wire (only connected in a data-only radio installation), and a 4-foot black wire (for the

ground connection). It is supplied with waterproof fuse holders, two AGC-type fuses, and non-insulated

ring terminals. The following installation procedures are recommended:

8.2.2.1 Black Wire Connection (Ground Wire)

1. Connect the radio’s DC Power Cable to the radio by mating its 3-pin connector to the radio’s 3-pin

power cable connector as follows: Visually align the key and firmly push and turn the outer locking

ring clockwise until it stops. A click will be sensed to confirm proper mating.

Do not confuse the radio’s DC Power Cable which has a 10-AWG red wire with the

control head’s DC Power Cable which has a 12-AWG red wire. The radio requires

much more DC operating current

than the control head. Therefore, it requires the

larger wire size of 10-AWG. The part number of the radio’s DC Power Cable is

CA-012365-001.

2. Prepare to connect the cable’s black wire to vehicle ground by locating an area of vehicle metal

within approximately two (2) feet of the radio. This surface must have a solid and stable connection

to vehicle ground. If not, add grounding strap(s) as necessary.

3. Strip the area of any paint or dirt to expose a bare metal surface, approximately ¾-inch square.

4. Drill a hole in the approximate center of the bare metal surface, and deburr it. A ⅜-inch non-

insulated ring terminal is supplied with the cable to make this ground connection. Therefore, hole

diameter should be appropriate for the utilized grounding screw/bolt size and type used to connect the

ring terminal to the bare metal surface. This hardware is not supplied.

5. Cut the black wire to the required length plus some additional length for a service loop, then strip

insulation back approximately ¼-inch.

6. Crimp a ⅜-inch non-insulated ring terminal (supplied with the cable) to the end of the black wire.

7. Attach the ring terminal and black wire to the bare metal surface using stainless-steel self-locking

hardware (i.e., machine screws with washers and locking nuts) or other appropriate hardware to

ensure a reliable terminal-to-metal contact. Tighten securely.

8. Apply an approved paint or rust-inhibitor over the remaining exposed bare metal surface and around

the ring terminal.

8.2.2.2 Red Wire and Main Fuse Holder Connection (Radio’s Main Power Wire)

1. Continue installation of the radio’s DC Power Cable by routing its 20-foot 10-AWG red wire to the

location of the vehicle’s battery (or its main DC bus bar or stud). Remove interior panels, door kick

panels, etc., and route the wire through existing channels in the vehicle body as necessary. Protect the

wire from possible chafing where necessary. Tie and stow the wire as necessary.

Plan the routing of the 10-AWG red wire carefully, using an existing access hole in the

vehicle’s firewall if possible. Alternately, drill a new hole approximately ⅜-inch in

diameter and install a small rubber grommet to protect the wire from chafing on the

hole’s sharp metal edge. To pr

event fumes from entering the passenger

compartment, this hole/grommet/wire combination must also be sealed with a

silicon-based sealer before completing the installation.

Do not install any wiring or fuse holder over or in the near vicinity of the vehicle’s

engine. Excessive engine heat can cause permanent damage to these components and

can lead to intermittent electrical connection to the battery.

Before making connections to the battery’s positive post, carefully disconnect the

battery’s negative

(ground) cable(s). This will prevent tools or other metallic

objects which come in contact with the battery’s positive terminal from shorting to

vehicle ground, causing sparks or even a fire or an explosion! When disconnecting

the negative cable(s), cover/insulate the positive post(s) if it is not already so a tool

cannot short between the posts. Some vehicles, such as those with diesel engines

have more than one battery; in this case, disconnect the negative cables at all

batteries.

Radio and control head fuses should not

be installed until all wiring is complete.

This will prevent the radio from powering up prematurely and/or causing an in-

rush of current that could lead to shorting of the battery, sparks, or even fire.

2. Obtain the orange waterproof (HFB type) fuse holder included with the DC Power Cable.

3. Observe and follow the previously presented WARNING!

CAUTION

WARNING

MM-012137-001, Rev. J

4. Cut the red wire to the required length for connection to the battery’s positive (+) battery terminal (or

the main DC bus bar or stud).

5. Prepare to splice the waterproof fuse holder into the red wire by cutting it again, at approximately

three (3) to six (6) inches from the end.

6. Strip all three (3) wire ends back approximately ⅜-inch each, place a fuse holder shell on each wire,

and securely crimp a fuse holder terminal to each wire end. Before crimping, verify fuse holder shells

are oriented in the correct directions (i.e., with each large end towards the wire end).

7. Label this fuse holder and red wire appropriately (e.g., “M5300 Main Power: 15-AMP FUSE”).

8. Do NOT install a fuse into the fuse holder at this time.

9. Crimp an appropriate electrical terminal to the short red wire. A corrosion-resistant ⅜-inch ring

terminal is included with the cable for this purpose, but another size corrosion-resistant terminal type

(not supplied) may be used if required.

10. Connect the ring terminal directly to the battery’s positive post (or if present, to a stud on the battery’s

main/non-switched power distribution terminal block).

Most M5300 radio installations have one or more control heads connected to the radio. In

an installation of this type, the white wire of the radio’s

DC Power Cable requires no

electrical connection. Rather than be cut from the cable, it is recommended that it be

rou

ted up to the vehicle’s fuse box, coiled, labeled, and stowed for possible future use.

The white wire of the control head’s

DC Power Cable is the radio installation’s ignition

sense input for on/off power control of both the control head and radio. Radio on/off

power control is accomplished by the control head. The control head “wakes-up” the radio

via data activity on the CAN link.

8.2.2.3 White Wire Connection (for Data-Only Radio Installations)

In the case of a data-only radio installation (i.e., no control head connected to the radio), the white wire of

the radio’s DC Power Cable is used as the radio installation’s ignition sense input. Therefore, it requires

electrical connection to a fused switched power source. The following procedure is recommended:

1. Route the 20-foot white wire of the radio’s DC Power Cable to the location of the vehicle’s switched

power source connection point, typically identified as “Accessory” power. Remove interior panels,

door kick panels, etc., and route the wire through existing channels in the vehicle body as necessary.

Protect the wire from possible chafing where necessary. Tie and stow the wire as necessary.

2. Connect this white wire through a fuse to the switched power source in accordance with the

instructions presented within the respective subsection of Section 8.3.4.2 (page 76) for the control

head’s white wire. Follow the procedure in Section 8.3.4.2.1 (page 76) if the vehicle’s ignition

switch/key must control the data-only radio’s on/off power. Follow the procedure in Section 8.3.4.2.2

(page 77) if a manually-controlled switch must control the data-only radio’s on/off power.

The “hot wired” wiring configuration (as depicted in Section 8.3.4.2.3) cannot be utilized

for the data-only radio, since this configuration does not employ the DC Power Cable’s

white wire.

8.2.3 Additional Hook-Up Required for a Data-Only Radio Installation

The CTLON (control power on) logic input of a data-only radio must be grounded per this procedure:

1. Obtain M5300/M7300 Option Cable CA-012349-001.

NOTE

MM-012137-001, Rev. J

2. Connect this cable’s male DB-44 connector to the female DB-44 connector on the rear of the radio.

Tighten the connector’s two (2) jackscrews firmly.

3. Using an appropriate DB-25 connector, hook-up wire, ring terminal and hardware (not supplied),

connect pin 14 of this cable’s DB-25 connector (P4 pin 14) to vehicle ground. This grounds the

radio’s CTLON input at pin 15 of the DB-44 connector. See Section 11.1 for additional information

on the Option Cable. Keep the length of the ground wire as short as reasonably possible.

4. Tie and stow the cable and wire as necessary to protect them from possible cable chafing.

When servicing the radio and/or control head, always manually power-down the radio

equipment via the control head’s on/off/volume control knob, and then remove the main

power fuse near the battery.

8.3 CH-721 CONTROL HEAD INSTALLATION

This section includes installation instructions for the CH-721 control head. If the radio is

being installed with and connected to an HHC-731 hand-held controller, skip this section

and advance to Section 8.4 which begins on page 79.

8.3.1 General Information

The remote-mount M5300 mobile radio must be connected to a control head to provide the operator-to-

radio interface. Two different control heads are available — the CH-721 Scan model and the CH-721

System model. See Figure 8-5 and Figure 8-6 respectively. The CH-721 Scan model control head features

three (3) large menu selection buttons. The System model control head has a 12-button keypad to allow

advanced operations without the need of a DTMF-capable microphone.

Figure 8-7 on page 71 illustrates the rear panel of the two control head models. Both models have

identical rear panels and rear panel connectors.

In a mobile installation, more than one control head can be connected to one mobile radio for multi-head

installations. A multi-head installation may be required in a vehicle such as a fire truck or any large

vehicle where more than one operator may require use of the radio. Multi-head installations also provide

other benefits such as intercom functionality between different operator positions.

8.3.2 Control Head Mechanical Installation

8.3.2.1 Selecting the Mounting Location

When selecting a location for the CH-721 control head, first observe the safety and operator-convenience

related information presented in Section 5.1 on page 36. Always consider and include clearance for the

microphone’s connector that must mate to the mic connector on the front panel of the head, and clearance

for the connectors/cables that must mate to the connectors on the rear panel of the head. The CH-721

control head can be mounted under or on top of a mounting surface (typically the vehicle’s dash) as space

permits using either the standard U-shaped mounting bracket or the optional mounting pedestal.

MM-012137-001, Rev. J

8.3.2.2 Using the Standard U-Shaped Mounting Bracket

If the standard U-shaped mounting bracket will be used to mount the control head, the following

mounting procedure is recommended. As listed in Table 4-6 on page 28, this bracket is item 2 in the

Installation Kit.

1. Using the mounting bracket as a template, mark and drill mounting holes into the mounting surface as

required. The round and elliptical holes in the bracket’s vehicle mounting surface are symmetrical, so

forwards/backwards positioning is not important during this step. However, positioning is important

in the next step.

Before drilling holes and/or installing mounting screws, verify these operations will not

damage or interfere with any existing vehicle component (the fuel tank, a fuel line, the

transmission housing, existing vehicle wiring, etc.). Always check to see how far the

mounting screws will extend below the mounting surface prior to installation. Always

deburr drilled holes before installing screws.

2. Postion the bracket at the mounting surface so the two round holes in its two side “ears” are nearest to

the normal location of the operator (typically towards the rear of the vehicle) and the two slotted holes

are furthest from the normal location of the operator (typically towards the front of the vehicle).

3. Install and tighten the mounting screws. Screws for mounting the bracket to the mounting vehicle’s

surface are not included, as all installations differ. Self-threading screws are recommended. Use of

self-drilling screws may cause damage to some mounting surfaces, such as a plastic dash panel.

4. Verify the bracket is held firmly to the mounting surface. Firm mounting prevents unreasonable

vibration, which could damage the control head and/or cause its cable connections to loosen.

5. Slide the control head into the bracket, placing the two pegs protruding from its left and right sides

into the respective round holes in the bracket’s two side “ears.”

6. In each side “ear” of the mounting bracket, start a #8-32 hex-socket-head cap (Allen) head screw with

a lockwasher and a flat washer by inserting the screw through the slotted hole in the bracket and then

into the threaded hole in the side of the control head. This hardware is included with Mounting

Bracket Kit. The lockwasher should be adjacent to the screw head and the flat washer should be

adjacent to the bracket. Turn each screw clockwise as observed from the head of the screw.

7. The control head can be positioned at various angles for best display viewing at the normal position

of the operator. As necessary, turn it on the pegs to a good position and tighten both screws using an

⅛-inch hex key (Allen) wrench until the control head is held firmly in place. Do not over-tighten.

8.3.2.3 Using the Mounting Pedestal (Optional)

An optional Mounting Pedestal, part number MACDOS0012, may be purchased separately to replace the

standard U-shaped mounting bracket. This pedestal can be attached to the bottom of the control head as

shown in Figure 8-9, and then mounted to a mounting surface below the two. It can also be attached to the

top of the head and then mounted to a mounting surface above the two.

8.3.3 Control Head-to-Radio CAN Cable Connections

8.3.3.1 General Information

A remote-mount radio installation requires a CAN cable between every two “CAN devices” and CAN

terminators on each end of the CAN link. The M5300 mobile radio is considered a CAN device, and each

CH-721 control head in the installation is also considered a CAN device. Figure 8-10 illustrates CAN

CAUTION

MM-012137-001, Rev. J

cable and CAN terminator connections for a single control head installation. Figure 8-11 illustrates this

for a multi-head control head installation where, for example, one control head is located at the main

operator location and another is located near the rear of the vehicle. Because CAN devices do not have

internal terminators, the CAN link must be terminated at both ends via external CAN terminators, as

depicted in the following figures.

NOTE: The M5300 mobile radio may be located in the middle of the CAN link. For a

2-head installation, two CAN cables would connect directly to the two CAN port

connectors on the rear of the radio, and each CH-721 control head would require a

CAN terminator. When the radio is in the middle of the CAN link, no CAN terminator

is required at the radio.

Figure 8-11: Typical CAN Link Connections for a Multi-Control Head Installation

Both the radio and the control head have two CAN ports to support “daisy-chaining” of multiple control

heads or other CAN devices. Figure 5-3 on page 38 shows the radio’s two CAN port connectors, which

MM-012137-001, Rev. J

are located near the center of the radio’s rear panel. Figure 8-7 on page 71 shows the two CAN port

connectors on the control head’s rear panel.

8.3.3.2 Make CAN Link Terminations and Cable Connection

Follow this procedure for an installation which has only one control head. For a multi-control head

installation, refer to Figure 8-11 as necessary.

1. Mate a CAN Terminator (item 5 in Table 4-6 on page 28) with either one of the two smaller 3-pin

CAN port connectors on the rear panel of the CH-721. This action makes the CAN termination at the

control head end of the CAN link.

When mating any CAN connection (terminators and cables) to a rear panel connector,

visually align the ¾-moon-shaped keys of the connectors, and then gently push and

turn the outer locking ring of the plug (male) connector clockwise until it stops. A mild

click will be sensed to confirm proper mating. Without visual alignment as a guide, it

is possible with excessive force t

o mate the CAN connectors improperly. Damage to

the connector(s) may result. Therefore, visual alignment is recommended when mating

CAN connectors.

2. Obtain a CAN Cable and mate it to the other CAN port connector on the rear panel of the CH-721.

Typically, item 6 in Table 4-6 is utilized, a 30-foot CAN cable.

3. Route the cable through the vehicle’s interior wire/cable channeling to the radio. Remove interior

panels, door kick panels, etc., as necessary. Protect the cable from possible chafing as necessary.

4. Mate this other end of the cable to one of the two CAN port connectors on the rear panel of the radio.

5. Mate another CAN Terminator to the other CAN port connector on the rear panel of the radio. This

action makes the CAN termination at the radio-end of the CAN link.

6. Loop, tie and stow the excess cable as necessary, leaving a service loop at the back of the radio and at

the back of the control head.

8.3.4 Control Head Power Cable Installation

Plan the route of the control head’s DC Power Cable carefully. Do not route the cable where it will be

damaged by heat sources or by casual contact, and protect it from wire chafe per standard installation

methods. The following procedures are recommended:

8.3.4.1 Install DC Power Cable and Make Power and Ground Connections

1. Connect the control head’s DC Power Cable (item 4 in Table 4-6 on page 28) to the large 3-pin

connector at the rear of the head. Visually align the key and gently push and turn the outer locking

ring clockwise until it stops. A click will be sensed to confirm proper mating.

2. At the back of the control head, locate a nearby section of vehicle chassis ground and strip this area of

any paint or dirt to expose a bare metal surface.

3. Cut the black wire of the control head’s DC Power Cable to the required length, plus a service loop of

at least six (6) inches, then strip it and crimp a ⅜-inch ring terminal to it. Two ring terminals of this

type are included with the cable.

4. Drill a hole as necessary and attach this ring terminal to chassis ground. Use stainless-steel self-

locking hardware (i.e., machine screws with washers and locking nuts) or other appropriate hardware

to ensure a reliable terminal-to-metal contact. Tighten securely.

NOTE

MM-012137-001, Rev. J

5. At the back of the control head, tie and stow the cable as necessary.

6. For the positive 12-volt DC main power source connection, route the cable’s red wire to the location

of an unswitched 12-volt DC power source, typically near the vehicle’s battery. Remove interior

panels, door kick panels, etc. Protect the wire from possible chafing as necessary. This is the control

head’s main DC power source.

7. Obtain one of the yellow waterproof (HFB-type) fuse holders included with the control head’s DC

Power Cable.

8. Cut excess length from the red wire and splice the fuse holder into it, near the location of the

unswitched 12-volt DC power source connection point.

9. Using an appropriate electrical terminal, connect the red wire to the unswitched DC power source. A

⅜-inch ring terminal is included with the cable for this purpose, but another terminal type (not

supplied) may be used if required.

10. Obtain the 5-amp AGC-type fuse included with the cable, and install it into the fuse holder.

Do not share the control head’s fuse with any other device. Doing so can cause excess

current to flow through the fuse, causing it to blow unnecessarily.

The fuse for the control head’s red wire is rated at 5 amperes. The 3-amp fuse included

with the cable must not be used for fusing the control head’s main DC power. It fuses

the head’s white wire.

8.3.4.2 Connect DC Power Cable’s White Wire

A review of the information presented in Section 8.2.1 (page 64) may be beneficial at this time. As

required per the chosen power-up configuration, connect the white wire by following one of the three

procedures presented in the respective sub-section that follows.

8.3.4.2.1 Control Head and Radio Turn on with Vehicle’s Ignition Switch/Key

With this wiring configuration, the control head and radio automatically turn on and off with the vehicle’s

ignition switch/key. The white wire of the control head’s DC Power Cable is sometimes referred to as the

“white ignition switch wire” or the “ignition sense input wire.” In this configuration, the white wire

connects to a switched power source, typically identified as “Accessory” power, that switches on and off

with the vehicle’s ignition switch/key. When using this configuration, the CH-721 control head’s

on/off/volume control must be left in the on position for automatic power-up/down to function properly.

The white ignition sense wire must be connected to a fused power source that switches

from approximately zero volts to approximately +13.6 volts when the vehicle’s ignition

switch/key is turned from the OFF position to the ACCESSORY and RUN positions.

Use of a switched power source that is subject to voltage changes as a result of other

actions, such as opening a vehicle door, may result in undesirable radio power cycles.

1. Locate the vehicle’s switched ignition or “Accessory” power connection point that will be used for

the switched ignition 12-volt DC power source. This point is typically located at or near the vehicle’s

fuse panel. It may be necessary to consult the vehicle manufacturer’s wiring diagram.

NOTE

CAUTION

NOTE

MM-012137-001, Rev. J

2. Route the white wire of the control head’s DC Power Cable from the back of the head to the area near

this connection point. Protect the wire from possible chafing as necessary.

3. Obtain one of the yellow waterproof (HFB-type) fuse holders included with the control head’s DC

Power Cable.

4. Cut excess length from the white wire and splice the fuse holder into it, near the location of the

connection point.

5. Using an appropriate electrical terminal, connect the white wire to the switched power connection

point. An open-barrel spade terminal is included with the cable for this purpose, but another type of

terminal (not supplied) may be used as required.

6. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder.

7. Tie and stow all wiring as necessary so it remains out of the way of casual contact and wire chafe is

avoided.

8.3.4.2.2 Control Head and Radio Turn On with a Manual Switch

With this wiring configuration, the control head and radio are manually turned on and off via an on/off

switch mounted separately from the control head and radio, not through the vehicle’s ignition switch/key.

This configuration is used when, for example, the radio must remain on even when the ignition key must

be removed from the vehicle and a separate on/off switch is acceptable and/or required. In this

configuration, the white wire connects to a fused switched power source such as that provided by a toggle

switch mounted on the vehicle’s dash panel. When using this configuration, the CH-721 control head’s

on/off/volume control must be left in the on position for automatic power-up/down to function properly.

1. Route the white wire of the control head’s DC Power Cable from the back of the head to an area near

the location of the panel-mounted on/off switch. Protect the wire from possible chafing as necessary.

2. Cut a short section (6 to 8 inches) off the end of the white wire and strip the ends.

3. Obtain one of the yellow waterproof (HFB-type) fuse holders included with the control head’s DC

Power Cable, and crimp one half of it to one end of the short section of wire.

4. Using an appropriate electrical terminal, connect this short white wire to unswitched 12-volt DC

power source at or near the vehicle’s fuse box.

5. Cut another section of white wire from the cable. This wire must be long enough to reach from this

fuse holder to the location of the panel-mounted on/off switch.

6. Strip one end of this wire and crimp the other half of the waterproof fuse holder to this wire end.

7. Strip the other end of this wire and, using an appropriate electrical terminal, connect it to the common

terminal of the switch.

8. Connect the white wire of the power cable to the load (switched) side of the switch.

9. If not already, mount the switch to the vehicle’s dash panel, or other customer-selected location.

10. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder.

11. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe

is avoided.

12. Label this power switch accordingly. For example: “RADIO ON/OFF.”

MM-012137-001, Rev. J

8.3.4.2.3 Control Head and Radio Are “Hot Wired”

In the “hot-wired” configuration, the control head and radio are turned on and off only by the control

head’s on/off/volume control located on the front panel of the control head. In this configuration, the

control head’s white wire must be connected to unswitched and fused 12-volt vehicle power. Follow the

procedure presented in Section 8.3.4.2.1, except connect the white wire to unswitched battery power

instead of switched (“Accessory”) power. Be sure to fuse this connection with the provided in-line fuse

holder and 3-amp AGC fuse.

8.3.5 Using Vehicle Fuse and T-Tap Kit (Optional) Instead of Waterproof Inline

Fuse Holder (Standard)

The waterproof inline fuse holder and AGC fuse included with the DC Power Cable must be used if the

white wire connection point is located in a harsh environment such as in the vehicle’s engine

compartment. In this case, disregard all information presented in this section, and follow one of the three

procedures presented in Section 8.3.4.2 to connect the white wire.

However, if the connection point is not in a harsh environment, such as under the vehicle’s dash panel,

Vehicle Fuse and T-Tap Kit FS24473 may be ordered and used to make the white wire connection. As

shown in Figure 8-12, this kit includes an ATM fuse holder and fuse, T-tap crimp terminals for tapping

into an existing vehicle switched power wire, and a quick-disconnect terminal. The following installation

procedure is recommended for this optional kit:

1. Locate the switched ignition or “Accessory” power wire (typically at or near the vehicle’s fuse block

or in a vehicle wiring harness) that will be used for the switched ignition power source. It may be

necessary to consult the vehicle manufacturer’s wiring diagram.

2. Route the white wire of the control head’s DC Power Cable from the back of the head to an area near

the switched ignition power source. At the back of the head, be sure to maintain a cable service length

of at least six (6) inches and do not loop the cable.

3. Cut a short section (6 to 8 inches) off the end of the white wire and strip each end of this short wire.

4. From the Vehicle Fuse and T-Tap Kit, locate the male-tab quick-disconnect terminal and crimp it to

one end of the short wire.

5. From the same kit, locate the ATM fuse holder and crimp it to the other end of the short wire. The

holder has built-in crimpable joints.

6. Cut the excess length from the white wire of the control head’s power cable, strip it, and crimp it to

the other side of the ATM fuse holder.

MM-012137-001, Rev. J

7. Pull enough of the switched ignition source wire out of the vehicle’s wiring harness so one of the

T-tap terminals may be attached to it.

8. Two T-tap terminals are included in the kit. Based on the gauge of wire, select the proper terminal

size: Red is for use with a 22 to 18-AWG wire, and blue is for use with an 18 to 14-AWG wire.

9. Attach the selected T-tap terminal by fitting the wire into its wire groove and snapping the two halves

together with a pair of pliers as shown in Figure 8-13.

10. Push the male-tab quick-disconnect terminal into the T-tap terminal’s inlet until it is fully engaged.

11. Install the 2-amp ATM fuse into the fuse holder. It is recommended that a piece of electrical tape be

wrapped around the fuse connection to keep the fuse from being jostled out of the holder.

12. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe

is avoided.

8.4 HHC-731 HAND-HELD CONTROLLER INSTALLATION

In a remote-mount M5300 mobile radio installation, the HHC-731 hand-held controller can be used in

place of the CH-721 control head. This easy-to-use hand-held mobile radio controller is primarily

designed for use in harsh environments such as maritime (i.e., boating) applications and All-Terrain

Vehicle (ATV) applications. The HHC-731 hand-held controller has easy-to-use buttons, a tough liquid-

crystal display (LCD), and a built-in microphone. As of the publication of this manual, only one (1)

8.4.1 Mounting the HHC-731 Interface Cable and Bracket

HHC-731 Interface Cable Mounting Bracket Kit KT-018752-001 is show in Figure 8-15. This kit

includes Bracket FM-018681-001 and mounting hardware, which secure the HHC-731 Interface Cable to

a mounting surface. In Table 4-7 on page 30, the cable is item 2 and the bracket is a part of the item 3 kit.

Figure 8-15: HHC-731 Interface Cable Mounting Bracket Kit KT-018752-001

Follow this procedure to attach the cable to the bracket, and to mount the bracket to a firm surface:

1. Attach the bracket to the large end of the cable using the two #6-32 machine screws and flatwashers

included in the bracket kit. As illustrated in Figure 8-16, the two can be attached either perpendicular

or parallel to each other. The “wings” of the bracket should be positioned away from the cable. Only

two of four center-most holes in the bracket are used.

2. Tighten the two (2) screws securely with a #1 Phillips screwdriver. Do not over-tighten.

3. Select a firm mounting surface near the controller, for the bracket. Review and follow the safety and

operator-convenience related information presented in Section 5.1 on page 36. Also, always consider

and include clearance for the mating of the two connectors on each side of the square end of the

cable, and for clearance for the two “pigtail” style cables extending from the bottom of the square

end.

4. Using the four (4) corner holes of the mounting bracket as a template, mark and drill mounting holes

into the selected mounting surface as required.

Before drilling holes and/or installing mounting screws, verify these operations will not

damage or interfere with any existing vehicle component (the fuel tank, a fuel line, the

transmiss

ion housing, existing vehicle wiring, etc.). Always check to see how far the

mounting screws will extend below the mounting surface prior to installation. Always

deburr drilled holes before installing screws.

5. Mount the mounting bracket and cable to the selected mounting surface using the thread-forming

screws, lockwashers, and flatwashers included with the HHC-731 installation kit, or other screws as

required per the mounting surface. Tighten the four screws securely, but do not over-tighten them.

6. Verify the mounting bracket is firmly mounted. Firm mounting prevents unreasonable vibration,

which could damage the cable and/or cause its cable connections to loosen over time.

8.4.2 Connecting CAN Link

Connect the CAN link between the radio’s CAN port and the CAN port connector of the HHC-731

Interface Cable in accordance with this procedure. Connections are illustrated in Figure 8-17:

1. Mate a CAN terminator to either one of the two small 3-pin CAN port connectors on the rear panel of

the radio. The CAN terminator is item 7 in Table 4-7.

2. Obtain a CAN cable and mate it to the other CAN port connector on the rear panel of the radio.

Typically, the 30-foot CAN cable is used, item 8 in Table 4-7. Other length CAN cables may be

used, as listed in Table 4-9 on page 35.

3. Route the CAN cable through the vehicle’s interior wire/cable channeling to the radio. Remove

interior panels, door kick panels, etc., as necessary. Do not route the cable where it will be damaged

by heat sources or by casual contact. Protect the cable from possible chafing and other damage as

necessary.

4. Mate the other end of the cable to the small 3-pin CAN port connector of the HHC-731 Interface

Cable.

CAUTION

5. Loop, tie and stow the excess cable as necessary, leaving a service loop at the back of the radio and at

the location of the interface cable.

8.4.3 Connecting DC Power

Plan the route of the DC Power Cable for HHC-731 hand-held controller carefully. Do not route it where

it will be damaged by heat sources or by casual contact, and protect it from wire chafe per standard

installation methods. The following procedures are recommended:

8.4.3.1 Install DC Power Cable and Make Power and Ground Connections

1. Connect the DC Power Cable (item 6 in Table 4-7) to the large 3-pin connector of the HHC-731

Interface Cable. Visually align the key and gently push and turn the outer locking ring clockwise until

it stops. A click will be sensed to confirm proper mating.

2. Near the HHC-731 Interface Cable’s mounting location, locate a nearby section of vehicle chassis

ground and strip this area of any paint or dirt to expose a bare metal surface.

3. Cut the black wire of the DC Power Cable to the required length, plus a service loop of at least six (6)

inches, then strip it and crimp a ⅜-inch ring terminal to it. Two ring terminals of this type are

included with the cable.

4. Drill a new hole as necessary and attach this ring terminal to chassis ground. Use stainless-steel self-

locking hardware (i.e., machine screws with washers and locking nuts) or other appropriate hardware

to ensure a reliable terminal-to-metal contact. Tighten securely.

MM-012137-001, Rev. J

Do not ground the black wire by attaching it via the same hardware that secures

the cable’s mounting bracket.

Before drilling holes and/or installing mounting screws, verify these operations will not

damage or interfere with any existing vehicle component (the fuel tank, a fuel line, the

transmission housing, existing vehicle wiring, etc.). Always check to see how far the

mounting screws will extend below the mounting surface prior to installation. Always

deburr drilled holes before installing screws.

5. Tie and stow the cable near the HHC-731 Interface Cable’s bracket.

6. For the positive 12-volt DC main power source connection, route the cable’s red wire to the location

of an unswitched 12-volt DC power source, typically near the vehicle’s battery. Remove interior

panels, door kick panels, etc. Protect the wire from possible chafing as necessary. This is the hand-

held controller’s main DC power source.

7. Obtain one of the waterproof (HFB-type) fuse holders included with the DC Power Cable.

8. Cut excess length from the red wire and splice the fuse holder into it, near the location of the

unswitched 12-volt DC power source connection point.

9. Using an appropriate electrical terminal, connect the red wire to the unswitched DC power source. A

⅜-inch ring terminal is included with the cable for this purpose, but another terminal type (not

supplied) should be used as required.

10. Obtain the 5-amp AGC-type fuse included with the cable, and install it into the fuse holder.

Do not share the HHC-731 hand-held controller’s fuse with any other device. Doing so

can cause excess current to flow through the fuse, causing it to blow unnecessarily.

The fuse for the HHC-731 hand-held controller’s red wire is rated at 5 amperes. The

3-amp fuse included with the cable must not be used for fusing the controller’s main

DC power. The 3-amp is used to fuse the controller’s white wire.

8.4.3.2 Connect DC Power Cable’s White Wire

Connect the DC Power Cable’s white wire by following one of the following three procedures, per the

customer’s required on/off power control method:

8.4.3.2.1 Hand-Held Controller and Radio Turn on with Vehicle’s Ignition Switch/Key

With this wiring configuration, the HHC-731 hand-held controller and the radio turn on and off with the

vehicle’s ignition switch/key (power on also requires pressing of the HHC-731’s front panel power on/off

button). The white wire of the HHC-731’s DC Power Cable is sometimes referred to as the “white

ignition switch wire” or the “ignition sense input wire.” In this configuration, the white wire of the

HHC-731’s DC Power Cable connects to a switched power source, typically identified as “Accessory”

power, that switches on and off with the vehicle’s ignition switch/key.
