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,
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
14221-1200-4000, Rev. A
7
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 Unity XG-100M 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 Unity XG-100M 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 Unity XG-100M 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).
Table 1-1 lists the recommended minimum safe lateral distances
for a controlled
environment and for unaware bystanders in an uncontrolled environment, from
transmitting antennas (i.e., monopoles over a ground plane, or dipoles) at rated radio

1.6 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 SystemsElectronic 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 CapsTo 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 EnergyTo 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
distance from the antenna as specified in Table 1-1. Refer to Section 1.2 for additional information.
Vehicles Powered By Liquefied Petroleum (LP) GasRadio 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 AirbagsFor 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.

1.7 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.
1.8 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 Unity XG-100M 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.
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.
CAUTION
14221-1200-4000, Rev. A
12
1.9 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 Unity XG-100M mobile radio, the CH-100 and
CH-721 control heads used with the radio, and related equipment. Procedures cover the mounting and
cabling of the equipment, as well as basic in-vehicle performance test procedures. In addition, important
product safety-related information is included.
3.1 GENERAL DESCRIPTION
The Unity XG-100M mobile radio is a high-performance multiband mobile radio with advanced
capabilities and unprecedented interoperability capability. The radio supports P25 trunked, P25
conventional, and analog conventional operations. It covers the 136 to 174 MHz VHF band, the 380 to
520 MHz UHF bands, and the 762 to 870 MHz bands. In the future, the radio will also cover the 30 to
50 MHz VHF-low band with the addition of an external RF power amplifier.
The Unity XG-100M mobile radio and related equipment are designed to operate in a mobile
environment, typically within a motor vehicle. The radio must be connected to an external vehicle-
mounted transmit/receive antenna system approved for use with the radio. Several different types of
antenna mounts and a multiband antenna element are approved and available for use with the radio. This
antenna element and the mounts are listed in Table 1-1 on page 8 and in Table 4-7 on page 30.
When operating on a VHF or UHF radio channel, the Unity XG-100M radio can provide 50 watts of
transmit output power in full-power transmit mode. When operating on a 700 or 800 MHz radio channel,
the radio can provide 35 watts of power in full-power transmit mode. As of the publication of this manual,
regulatory certification limits transmitter power to 26.3 watts in the 700 MHz band.
Front-mount and remote-mount 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 or on an equipment shelf. Three (3) different control heads are available
for use with the radio. All three are available in both a remote-mount and a front-mount configuration:
CH-100 Control HeadShown in Figure 3-1 below in a front-mount radio configuration, the
CH-100 features a 4.3-inch touchscreen sunlight-readable LCD color display, providing an easy-to-
use menu-driven operator interface. This head also features a Bluetooth wireless interface for
connection of optional equipment and to support radio and control head programming via a wireless
connection. The front panel of the CH-100 head also features an easy-to-use on/off/volume control
and group/channel selection controls, an emergency button, a home button, a USB programming port,

and a microphone connector.
CH-721 Scan Model Control HeadThis head features a large 3-line graphical vacuum-fluorescent
display and easy-to-use front panel controls, including three (3) large menu-related buttons. Figure
8-5 on page 58 details all front panel components.
CH-721 System Model Control HeadFigure 3-2 on page 19 illustrates the CH-721 System model
control head in a front-mount configuration. This head is very similar to the CH-721 Scan model
control head. It has an identical 3-line graphical vacuum-fluorescent display. Also, front panel
controls are identical to those on the Scan model control head with the exception of the 12-key
keypad and smaller menu-related buttons. The 12-key numeric keypad provides Dual-Tone Multi-
Frequency (DTMF) functionality and advanced operator system/group selection control via the
control head’s front panel. Figure 8-6 on page 58 details all front panel components.
All three (3) control heads feature a large easy-to-use volume/on/off rotary control and a rotary
system/group/channel selection control. In addition, each head also has a front panel microphone
connector, and an internal high-power audio amplifier to drive an externally-connected speaker. All heads
used with remote-mount radios have rear panel connectors for DC power, CAN link, speaker audio
output, serial port, and optional accessory connections.
In a remote-mount radio configuration, a Controller Area Network (CAN) cable provides the radio-to-
head connection. 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. The CAN link is basically
2-wire (with shield ground) daisy-chained high-speed serial data link. For proper operation, the CAN link
must be terminated on each end with a simple resistive-type terminator.
The CAN link is also used to interconnect additional control heads to a radio in a multi-head installation.
In a multi-head mobile radio installation, more than one control head is utilized with a radio. A multi-
head installation may be required in a vehicle such as a fire truck or any large vehicle where more than
one operator position must support radio use. For example, a ladder fire truck could have a front-mount
XG-100M mobile radio mounted under the truck’s dash panel and a remote-mount control head mounted
at the ladder operator’s position. Each control head in a multi-head installation is equipped with an
external speaker, a microphone, and optionally-connected equipment. Multi-head installations provide
other benefits such as intercom functionality. The XG-100M mobile radio can support up to six (6)
control heads.
The CH-100 control head cannot be mixed with the CH-721 control head within the same
multi-head radio installation. For example, a remote-mount CH-721 cannot be connected
to a front-mount XG-100M radio with a CH-100 control head.
The radio and control head 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 control head(s) connected to the radio is also powered by the same
DC power source, but separately fused. When the control head 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. When
a control head is employed in a remote-mount mobile radio installation, an audio amplifier in the head
drives the speaker.

For data communications, the radio has an industry-standard TIA/EIA/RS-232C type 9-pin serial
interface port for connecting optional data-type equipment, 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. This port can also be used for radio program operations, and radio diagnostic functions.
The radio also has a built-in Global Positioning System (GPS) receiver. This receiver provides position
and speed tracking and accurate time via the control head’s display. It also provides GPS
NMEA-formatted serial data to several pins on the radio’s rear panel 44-pin connector. This is provided
for external equipment running third-party GPS-related software. The GPS receiver’s 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. As of the
publication of this manual, over-the-air GPS data messaging is not supported.
For over-the-air secure radio communications, the Unity XG-100M mobile radio may be optionally
equipped for 256-Bit Advanced Encryption Standard (AES) voice encryption or 64-bit Digital Encryption
Standard (DES) 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. DES encryption is offered in both standard Output Feedback (DES-OFB)
and Cipher Feedback (DES-CFB) formats.
The Unity XG-100M mobile radio and its control heads 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.

5.3 LOCATING COMPONENTS
Plan the mounting locations of all components (radio, control head, 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 for the radio and control heads are listed in
Section 2.1 on page 13. 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 and control
heads are listed in Section 2.1 on page 13. 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.

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 (see page 6). A transmitting
antenna must be installed in accordance with the guidelines presented in both the
REGULATORY AND SAFETY INFORMATION section, and in this section.
Figure 6-1 below illustrates recommended antenna mounting locations. Use this figure together with the
minimum safe lateral distance data presented in Table 1-1 on page 8 as a guide for determining the best
possible antenna mounting location(s). This is necessary in order to reduce human exposure to radio
frequency (RF) electromagnetic energy when the radio is transmitting. The radio’s antenna(s) must be
located on the vehicle as shown in Figure 6-1. Always follow antenna mounting and installation
instructions presented in this section and any instructions provided with an antenna.
See Table 4-7 on page 30 for detailed descriptions of the antenna element and the antenna mounts.

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). For optimal performance, the mounting area under the antenna must be 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).
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). The antenna 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 a GPS combination-type antenna is not utilized for the mobile radio installation and the radio’s GPS
receiver functions must be available for operational use, a stand-alone GPS receive antenna must be
separately mounted and connected to the radio. The vehicle’s rear deck lid (location in Figure 6-1) 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.
Table 4-7 (page 30) and Figure 6-1 list the mobile radio antennas available for use with the radio. As
presented in the previous section, various mounting locations exist. Optimal performance is achieved via
a rooftop antenna mounted in the direct center of the motor vehicle’s roof.
6.2.1 Installing Antenna Mounts AN-125001 -002 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 Antenna Mount AN-125001-002
This standard ¾-inch NMO antenna mount requires 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.
6.2.1.2 Thick-Roof Antenna Mount AN-125001-004
This thick-roof NMO antenna mount uses either a -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).
NOTE
14221-1200-4000, Rev. A
36
For thick-roof antenna mount AN-125001-004, using a -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 -inch
hole, the antenna mount’s bushing
assembly must be inserted from the underside of the mounting surface.
When using a ¾-inch mounting hole to mount thick-roof antenna mount AN-125001-
004, the thickness of the mounting surface must be at least -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-125001-002 and -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 21
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 -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. -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 to
(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
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.
NOTE
CAUTION
14221-1200-4000, Rev. A
37
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 -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 (-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 6-2 and Figure 6-3, 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.

7 FRONT-MOUNT RADIO INSTALLATION
This section includes detailed instructions for mechanically installing and wiring a
front-mount Unity XG-100M mobile radio. For remote-mount Unity XG-100M mobile
radio installation procedures, refer to Section 8 which begins on page 49.
7.1 MOUNTING THE FRONT-MOUNT RADIO
The Mounting Bracket Kit for the front-mount Unity XG-100M 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 7-1.
Both the radio and the mounting bracket have multiple holes in both sides for adjusting the radio within
the bracket. For the best viewing angle, the radio can be secured in the bracket in a tilted position. 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 view the radio’s control head. Two (2) screws per bracket/radio side are used when
the front-to-rear offset is employed.
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 Unity XG-100M radio weighs approximately 6 pounds (2.7 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 is unsafe. A weak mount could turn the radio and its mounting
bracket into a dangerous 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 improvin
g 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 improp
erly mounted
Unity XG-100M radio may experience degradation in the quality of voice and data
communications.

7.1.1 Mounting Bracket Installation
The front-mount Unity XG-100M radio’s mounting bracket is a part of the Front-Mount Mounting
Bracket Kit KT101533V1. Kit contents are shown in Figure 7-1. This kit is Item 1 listed in Table 4-3
(page 24).

Figure 7-1: Front-Mount Mounting Bracket Kit KT101533V1
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 view the radio’s control head.
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 view the radio’s control head.
2. At the rear of the radio, verify sufficient clearance is available for cables and service access.
14221-1200-4000, Rev. A
43
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, 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, electronic control modules, etc.). Always
check to see how far the mounting screws will extend beyond 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 socket (Allen) head
screws included with the Mounting Bracket Kit. These screws have captive lockwashers. Kit contents
are shown in Figure 7-1. This kit is Item 1 listed in Table 4-3 (page 24).
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 for securing excess cable.
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
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. Otherwise, the
radio will remain off when the ignition switch/key is on.
In a front-mount Unity XG-100M 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. Otherwise, the radio will remain off when the
switch is on.
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.
7.2.2 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 (for the switched power source connection), and a 4-foot black wire (for the ground
connection). It is supplied with waterproof fuse holders, three (3) AGC-type fuses, and non-insulated ring
terminals. Only two of the three fuses are utilized in this application. The following installation
procedures are recommended:
7.2.2.1 Black Wire Connection (Ground Wire)
1. Temporarily connect the radio’s DC Power Cable to the radio by mating the cable’s 3-pin connector
to the radio’s 3-pin power connector. Locking the two connectors is not necessary at this time.
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
14221-1200-4000, Rev. A
45
3. Verify the black wire has sufficient length to reach the ground point. If not, it can be extended by
splicing a 10-AWG wire to it. In this case, use approved wiring splicing methods and materials.
4. Strip the area of any paint or dirt to expose a bare metal surface, approximately ¾-inch square.
5. Drill a hole in the approximate center of the bare metal surface, and deburr it. A -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.
6. Cut the black wire to the required length plus some additional length for a service loop, then strip
insulation back approximately ¼-inch.
7. Crimp a -inch non-insulated ring terminal (supplied with the cable) to the end of the black wire.
8. Fully connect the radio’s DC Power Cable to the radio by mating its 3-pin connector to the radio’s
3-pin power 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.
9. 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.
10. 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.
Battery Ground WARNING: 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.
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.
WARNING
CAUTION
14221-1200-4000, Rev. A
46
Do not install any wiring or fuse holder over or in the 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.
2. Obtain the orange waterproof (HFB type) fuse holder included with the DC Power Cable.
3. Observe and follow the previously presented Battery Ground WARNING!
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 -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). If necessary, a small
amount of cable soap may be used to help slip the wire through the small end of the fuse holder’s
insulator.
7. Label this fuse holder and red wire appropriately (e.g., “XG-100M Radio Main Power: 20-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 -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 Unity XG-100M mobile radio installation may be connected to additional
control heads to form a multi-head radio installation. In this case, refer to Section 8.3 for
control head installation procedures.
The CH-100 control head cannot be mixed with the CH-721 control head within the same
multi-head radio installation. For example, a remote-mount CH-721 cannot be connected
to a front-mount XG-100M radio with a CH-100 control head.
7.2.2.3 White Wire Connection
A review of the information presented in Section 7.2.1 (page 44) 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 turn 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 on/off/volume control must be left in the on position.
Otherwise, the radio will remain off when the ignition switch/key is on.
CAUTION
NOTE
NOTE
14221-1200-4000, Rev. A
47
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 yellow waterproof (HFB-type) fuse holder included with the radio’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. Continue with the speaker installation procedures presented in Section 9.1 on page 68.
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 on/off/volume control must be
left in the on position. Otherwise, the radio will remain off when the switch is on.
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 yellow 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.
NOTE
14221-1200-4000, Rev. A
48
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 68.
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
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 4-3).
A front-mount Unity XG-100M mobile radio installation may be connected to additional
control heads to form a multi-head radio installation. In this case, refer to Section 8.3 for
control head installation procedures.
In a multi-head radio installation with a front-mount XG-100M mobile radio, at least one
CAN port connector on the rear of the radio will not have a CAN terminator mated to it.
Instead a CAN cable will be mated to it for linking to the additional control head(s).
The CH-100 control head cannot be mixed with the CH-721 control head within the same
multi-head radio installation. For example, a remote-mount CH-721 cannot be connected
to a front-mount XG-100M radio with a CH-100 control head.

radio installation procedures, refer to Section 7 which begins on page 41.
8.1 MOUNTING THE REMOTE-MOUNT RADIO
This section provides details on mounting a remote-mount Unity XG-100M mobile radio in the vehicle.
Control head installation procedures are included in Section 8.3 which begins on page 56.
The remote-mount radio weighs approximately 5.25 pounds (2.38 kilograms). The preferred mounting of
the radio is on top of a firm, flat surface. Radio dimensions included in Section 2.1 on page 13.
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 is unsafe. A weak mount could turn the radio and its mounting
bracket into a dangerous 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, electronic control modules, etc.). Always
check to see how far the mounting screws will extend beyond 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 8-1. This is item 1 in the respective remote-mount
installation kit (i.e., Table 4-4 for CH-100 control head and Table 4-5 for the CH-721 control head).
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.

to Bracket
Figure 8-1: Remote-Mount Mounting Bracket Kit KT23117
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 (i.e., cable connection end), 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.
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, 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.
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 the
respective remote-mount installation kit). 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 for securing excess cable.
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.
8.2 REMOTE-MOUNT RADIO’S DC POWER INSTALLATION
8.2.1 Overview of On/Off Power Wiring Configurations
Radio on/off power control is accomplished by the 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 on/off/volume control must be left in the on position. Otherwise,
the radio will remain off when the ignition switch/key is on.
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
on/off/volume control must be left in the on position. Otherwise, the radio will remain off when the
switch is on.
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.
NOTE
NOTE
14221-1200-4000, Rev. A
52
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 not used.
8.2.2 DC Power Cable, Main Fuse Holder, and CAN Cable Installation
The radio’s DC Power Cable has a 3-pin connector, a 20-foot red wire for the main power connection, a
4-foot black wire for the ground connection, and a 20-foot white wire which is not used. The cable is
supplied with waterproof fuse holders, three (3) AGC-type fuses, and non-insulated ring terminals.
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 and it has two wires which are 20-feet long.
In a typical vehicle installation, as a time saving measure, the majority of the length of the CAN cable
between the remote-mount radio and the control head can be routed together with the red wire of the
radio’s DC Power Cable. Also, any necessary option/accessory cables from the back of the radio can also
be routed with this wire and cable.
The following wire and cable installation procedures are recommended:
8.2.2.1 Black Wire Connection (Ground Wire)
1. Obtain the radio’s DC Power Cable, part number CA-012365-001.
2. Temporarily connect this cable to the radio by mating the cable’s 3-pin connector to the radio’s 3-pin
power connector. Locking the two connectors is not necessary at this time.
3. 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.
4. Verify the black wire has sufficient length to reach the ground point. If not, it can be extended by
splicing a 10-AWG wire to it. In this case, use approved wiring splicing methods and materials.
5. Strip the area of any paint or dirt to expose a bare metal surface, approximately ¾-inch square.
6. Drill a hole in the approximate center of the bare metal surface, and deburr it. A -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.
7. Cut the black wire to the required length plus some additional length for a service loop, then strip
insulation back approximately ¼-inch.
8. Crimp a -inch non-insulated ring terminal (supplied with the cable) to the end of the black wire.
9. Fully connect the cable to the radio by mating its 3-pin connector to the radio’s 3-pin power
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.
10. 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.
CAUTION
14221-1200-4000, Rev. A
53
11. 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, Main Fuse Holder Connection (Radio’s Main Power Wire), and
CAN Cable
In a typical vehicle installation, the majority of the CAN cable between the remote-mount radio and the
control head can be routed through the vehicle along with the 10-AWG red wire of the radio’s DC power
cable. This is a time-saving measure. Also, any necessary option/accessory cables from the back of the
radio can also be routed with this wire and cable within the vehicle’s interior (i.e., up to but not through
the vehicle’s firewall). The following installation procedure is recommended:
1. From the installation kit, obtain the CAN cable, part number CA-009562-030.
2. Remove interior panels, door kick panels, etc., as necessary to route the 10-AWG red wire and the
CAN cable from the area of the remote-mount radio (typically near the rear of the vehicle) to an area
near the vehicle’s firewall.
3. Route the red wire and the CAN cable through existing channels in the vehicle body to an area near
the vehicle’s firewall. Leave service loops at the rear of the radio. CAN cable installation is
completed per a later procedure in this manual (Section 8.3.5).
4. Continue installation of the 10-AWG red wire by routing it through the vehicle’s firewall to the
location of the vehicle’s battery (or its main DC bus bar or stud). Use an existing access hole in the
vehicle’s firewall if possible. Alternately, drill a new hole approximately -inch in diameter and
install a small rubber grommet to protect the wire from chafing on the hole’s sharp metal edge.
To prevent fumes from entering the passenger compartment, any
hole/grommet/wire combination in the vehicle’s firewall must be sealed with a
silicon-based sealer before completing the installation.
5. Protect the red wire and the CAN cable from possible chafing where necessary. Tie and stow them as
necessary.
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.
Battery Ground WARNING: 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 mor
e 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.

6. Obtain the orange waterproof (HFB type) fuse holder included with the DC Power Cable.
7. Observe and follow the previously presented Battery Ground WARNING!
8. 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).
9. 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.
12. Strip all three (3) wire ends back approximately -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). If necessary, a
small amount of cable soap may be used to help slip the wire through the small end of the fuse
holder’s insulator.
10. Label this fuse holder and red wire appropriately (e.g., “XG-100M Radio Main Power: 20-AMP
FUSE”).
11. Do NOT install a fuse into the fuse holder at this time.
13. Crimp an appropriate electrical terminal to the short red wire. A corrosion-resistant -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.
12. 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 Unity XG-100M 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 routed 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.
8.3 CONTROL HEAD INSTALLATION
The remote-mount Unity XG-100M mobile radio must be connected to a control head to provide the
operator-to-radio interface. Three (3) different control heads are availableThe CH-100 control head,
and the CH-721 Scan and System model control heads. See Figure 8-3 through Figure 8-6 respectively. A
control head is interfaced to the radio via a CAN cable. Each head is separately fused and powered by an
individual DC power cable.
8.3.1 General Information on the CH-100 Control Head
The CH-100 features a 4.3-inch touchscreen sunlight-readable LCD color display, providing an easy-to-
use menu-driven operator interface. This head also features a Bluetooth wireless interface for connection
of optional equipment and to support radio and control head programming via a wireless connection. The
front panel of the CH-100 head also features an easy-to-use on/off/volume control and group/channel
selection controls, an emergency button, a home button, a USB programming port, and a microphone
connector.
The CH-100 control head’s mounting bracket allows pitch-axis (tilt) positioning for best viewing angle.
Pitch adjustments are accomplished by loosening thumbscrews on each side of the bracket, changing the
NOTE
14221-1200-4000, Rev. A
57
pitch/tilt of the head as needed, and then retightening the thumbscrews. A 150-degree pitch/tilt angle is
provided. A gimbal-type mounting pedestal is also available, as illustrated in Figure 8-9 on page 60.
Figure 8-3: CH-100 Control Head Front Panel
Figure 8-4: CH-100 Control Head Rear Panel (shown with Standard Mounting Bracket)
8.3.2 General Information on the CH-721 Control Head
The CH-721 Scan and System model control heads feature a large easy-to-read 3-line graphical vacuum
fluorescent display, an on/off/volume control, menu controls and buttons, trunking mode buttons, an
emergency/home button, a scan on/off button, and three (3) preset buttons. Other front panel components
include a microphone connector and two LED-type indicators. One LED indicator is the busy indicator
that lights when the radio is receiving a call and one is the transmitter-enabled indicator that lights when
the radio is transmitting. All buttons are backlit for viewing in low-light conditions.
As illustrated in Figure 8-5, the CH-721 Scan model control head features three (3) large menu selection
buttons. The System model control head, shown in Figure 8-6, has a 12-key keypad to allow advanced
operations without the need of a DTMF-capable microphone.

8.3.3 Multi-Head Radio Installations
In a multi-head mobile radio installation, more than one control head is utilized with a radio. A multi-
head installation may be required in a vehicle such as a fire truck or any large vehicle where more than
one operator position must support radio use. For example, a ladder fire truck could have a front-mount
XG-100M mobile radio mounted under the truck’s dash panel and a remote-mount control head mounted
at the ladder operator’s position. Each control head in a multi-head installation is equipped with an
external speaker, a microphone, and optionally-connected equipment. Multi-head installations provide
other benefits such as intercom functionality. The XG-100M mobile radio can support up to six (6)
control heads.
The CH-100 control head cannot be mixed with the CH-721 control head within the same
multi-head radio installation. For example, a remote-mount CH-721 cannot be connected
to a front-mount XG-100M radio with a CH-100 control head.
For a multi-head radio installation, mechanical installation and DC power connections for each additional
head are accomplished in the same manner as for a single-head remote-mount radio installation. See
Sections 8.3.4 and 8.3.6 respectively.
Refer to Section 8.3.5 for CAN link installation information. Figure 8-11 in that section illustrates CAN
cable and CAN terminator connections for a two-head installation.
8.3.4 Control Head Mechanical Installation
Prior to installing the control head, verify it has the proper software version installed and
verify it has been properly configured for customer use. Consult the radio system
administration personnel as necessary.
8.3.4.1 Selecting the Mounting Location
When selecting a location for the control head, first observe the safety and operator-convenience related
information presented in Section 5.1 on page 32. 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 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.
The size and weight of the control head necessitate less stringent mounting requirements than the radio.
However, like the radio, the control head must be mounted to a mechanically-rigid surface. The control
head must not vibrate when the vehicle is in motion and it must remain stable during normal operations
by an operator (i.e., button presses, knob rotation, excessive tugs on the mic cord, etc.). If the control
head is mounted to a plastic dash panel, either fender washers or a field-fabricated metal backing plate
should be utilized to mount the head’s bracket to the plastic dash panel.

8.3.4.2 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.
1. Obtain the mounting bracket from the respective installation kit. For the CH-100 control head, this is
item 2, as illustrated Table 4-4 on page 25. For the CH-721 control head, this is item 2 as illustrated
in Table 4-5 on page 27.
2. 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, electronic control modules, etc.). Always
check to see how far the mounting screws will extend beyond the mounting surface
prior to installation. Always deburr drilled holes before installing screws.
3. 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).
4. 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.
5. 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.
6. 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.”
7. 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.
8. The control head can be positioned at various angles for best display viewing at the normal position
of the operator. As necessary, tilt it on the pegs to a good position and tighten both screws using an
-inch hex key (Allen) wrench until the control head is held firmly in place. Do not over-tighten.
8.3.4.3 Using the Optional Gimbal Mounting Pedestal
An optional Gimbal Mounting Pedestal, part number MACDOS0012, may be purchased separately to
replace the standard U-shaped mounting bracket.
For the CH-100 control head, the MACDOS0012 pedestal attaches to the bottom of the head with
Pedestal Mounting Kit 12099-1501-01. This kit includes Adapter Bracket 12099-0341-01 and stainless-
steel #8 hardware. The complete assembly is then mounted to a mounting surface located below the
assembly, such as the top of the vehicle’s dash panel.
CAUTION
14221-1200-4000, Rev. A
62
For the CH-721 control head, the MACDOS0012 pedestal attaches directly to the bottom of the control
head as shown in Figure 8-9. The pedestal is then mounted to a mounting surface located below or above
the assembly.
Be sure to use the #8-32 screws (with washers) supplied with the pedestal to attach it to
the head. These screws are the correct length for this application and they have SEMS-
type washers that will not easily separate from the screw. Installing the wrong screws or
the correct screws without the washers and/or the bracket in place could punch-out the
floor of the threaded holes, possibly damaging internal components of the head.
8.3.5 Control Head-to-Radio CAN Cable Connections
8.3.5.1 General Information
A remote-mount radio installation requires a CAN cable between every two CAN devicesand CAN
terminators on each end of the CAN link. The Unity XG-100M mobile radio is considered a CAN device,
and each control head in the installation is also considered a CAN device. Figure 8-10 illustrates CAN
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.
Both the radio and the control head have two CAN ports to support “daisy-chaining” of multiple control
heads or other CAN devices. Figure 3-2 on page 19 shows the radio’s two CAN port connectors, which
are located near the center of the radio’s rear panel. Figure 8-7 on page 59 shows the two CAN port
connectors on the control head’s rear panel.

NOTE #2: The XG-100M 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 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. The radio can support up to six (6) control heads.

Figure 8-11: Typical CAN Link Connections for a Multi-Control Head Installation
8.3.5.2 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. Obtain the two (2) CAN terminators, part number CD-014027-001, from the installation kit.
2. Mate one terminator to either one of the two smaller 3-pin CAN port connectors on the rear panel of
the control head. 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 to mate the CAN connectors improperly. Damage to
the connector(s) may result. Therefore, visual alignment is recommended when mating
CAN connectors.
3. Per the procedure in section 8.2.2.2, the CAN cable was partially installed along with the red wire of
the radio’s DC Power Cable. Continue CAN cable installation by routing it to the area near the rear
of the control head.
4. Mate one end of the CAN cable to the other CAN port connector on the rear panel of the control head.
NOTE
14221-1200-4000, Rev. A
64
5. If not already mated, mate the other end of the CAN cable to one of the two CAN port connectors on
the rear panel of the radio.
6. Mate the second 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.
7. Any necessary option/accessory cables from the back of the radio can also be routed with this wire
and cable within the vehicle’s interior (i.e., up to but not through the vehicle’s firewall). For example,
if the mobile radio installation must be interfaced to GPS, simultaneous routing of the related
interface cables along with the CAN cable can be time-saving. For GPS equipment cable part
numbers and cable installation procedures, refer to Section 12.
8. Loop, tie, and stow the cable(s) as necessary, leaving a service loop at the back of the radio and at the
back of the control head. Protect the entire length of the cable(s) and wire(s) from possible chafing.
8.3.6 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:
8.3.6.1 Install DC Power Cable and Make Power and Ground Connections
1. Obtain the control head’s DC Power Cable from the respective installation kit. For the CH-100
control head, this is item 4 illustrated in Table 4-4. For the CH-721 control head, this is item 4
illustrated in Table 4-5.
2. Connect this cable 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.
3. 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.
4. 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 -inch ring terminal to it. Two ring terminals of this
type are included with the cable.
5. 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 reliable terminal-to-metal contact. Tighten securely.
6. At the back of the control head, tie and stow the cable as necessary.
7. 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.
8. Obtain one of the yellow waterproof (HFB-type) fuse holders included with the control head’s DC
Power Cable.
9. 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. If necessary, a small amount of cable soap
may be used to help slip the wire through the small end of the fuse holder’s insulator.
10. Using an appropriate electrical terminal, connect the red wire to the unswitched DC power source. A
-inch ring terminal is included with the cable for this purpose, but another terminal type (not
supplied) may be used if required.
14221-1200-4000, Rev. A
65
11. 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.
8.3.6.2 Connect DC Power Cable’s White Wire
A review of the information presented in Section 8.2.1 (page 51) 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.
8.3.6.2.1 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 on/off/volume control must be
left in the on position. Otherwise, the radio will remain off when the ignition switch/key is on.
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 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.

8.3.6.2.2 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 on/off/volume control
must be left in the on position. Otherwise, the radio will remain off when the switch is on.
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.”
8.3.6.2.3 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 8.3.6.2.1, 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.
8.3.7 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 8.3.6.2 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
14221-1200-4000, Rev. A
67
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.
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.

9 SPEAKER INSTALLATION
9.1 FRONT-MOUNT RADIO INSTALLATION
In a front-mount radio installation, total speaker cable length (of both cables) is approximately 10 feet
(308 centimeters). Therefore, to include service loops in these cables, the speaker must be mounted within
approximately 9.5 feet (290 centimeters) of the radio.
1. Select a location for the speaker that will allow for proper listening range at moderate volume.
2. Install the speaker using the hardware and mounting bracket supplied with it. For the speaker’s part
number, see Table 4-3 on page 24.
3. Route the speaker cable to the rear of the radio.
4. Connect Option Cable CA-012349-001 (item 5 in Table 4-3) to the DB-44 connector on the rear of
the radio. Tighten the cable’s two (2) jackscrews securely. See Section 11.1 for additional information
on this cable.
If the approximate speaker cable length of 10 feet is not long enough, 20-foot Speaker-
Only Option Cable CA-012349-007 can be used in place of Option Cable CA-012349-
001. However, Speaker-Only Option Cable CA-012349-001 does not
support any
optional connections at the 44-pin (DB-44) connector on the rear of the radio. Use of
Speaker-Only Option Cable CA-012349-007 will provide approximately 25 feet of total
cable length for the speaker connection.
5. Mate the Option Cable’s 2-pin connector (identified P2 with green and white wires) to the 2-pin
connector on the end of the speaker cable. A mild click will be sensed to confirm proper mating.
6. Route the cables out of the way of casual contact. Tie and stow as necessary.
9.2 REMOTE-MOUNT RADIO INSTALLATION
In a remote-mount mobile radio installation, an audio amplifier in the head drives the external speaker.
For this case, total speaker cable length of both cables between the control head and speaker is
approximately five (5) feet. Therefore, to include service loops in these cables, the speaker must be
mounted within approximately 4.5 feet of the installation’s control head.
1. Select a location for the speaker that will allow for proper listening range at moderate volume.
2. Install the speaker using the hardware and mounting bracket supplied with it. For the speaker’s part
number, see Table 4-5 (page 27).
3. Route the speaker cable to the rear of the control head.
4. Mate the 6-inch speaker cable, part number MAMROS0034-NN006, to the 2-pin connector at the rear
of the control head by visually aligning the ¾-moon-shaped keys of the connectors, and then pushing
and turning the outer locking ring of the cable connector clockwise until it stops. A mild click will be
sensed to confirm proper mating.
5. Connect the speaker cable’s 2-pin plastic connector to the respective mating connector on the 6-inch
speaker cable.
6. Route the cables out of the way of casual contact. Tie and stow as necessary.
In a multi-head installation, an audio amplifier in each control head drives the head’s
speaker. Therefore, no special speakers or relays are needed.

10 MICROPHONE ATTACHMENT
There are several versions of microphones available for use with the radio. Each has a 17-pin connector
that mates with the mic connector on the front panel of the control head. The mic’s connector includes a
captive thumbscrew that secures it to the mic connector on the front panel of the control head. A
microphone clip is included with each microphone. The radio can be configured to provide a monitor
function when the microphone is cradled in the clip. Connect the mic to the control head and install the
clip as follows:
1. Position the mic’s connector just in front of the control head’s mic connector so its male pins can
engage straight into the female (socket) pins of the control head’s mic connector. The thumbscrew
must be oriented directly below the hanging mic cable.
2. Mate the two connectors by pressing them fully together. Do not apply any force to the thumbscrew
when mating the connectors.
3. Tighten the thumbscrew securely. Do not over-tighten it.
4. Using the microphone clip as a template, drill mounting holes in the surface of the selected location.
5. Select a mounting surface location that has clearance for the mic when it is clipped to the clip, and
then attach the microphone clip to the surface. Use self-locking hardware (i.e., machine screws with
washers and locking nuts), self-drilling screws, or other appropriate hardware as necessary. Tighten
securely. The microphones have integrated hookswitches. Therefore, the microphone clip does not
require grounding.
6. Clip the microphone to the clip.

11 OPTIONAL CABLES AND CONNECTIONS
11.1 OPTION CABLE CA-012349-001
Option Cable CA-012349-001 connects to the 44-pin I/O connector on the rear of the radio. It breaks out
into several smaller standardized connectors, allowing straightforward access to external I/O interfaces
provided by the radio. The cable also shortens radio removal and re-installation time when required. The
cable is shown in Figure 11-1 below. The cable’s 44-pin D-subminiature connector that mates with the
connector on the rear of the radio is identified P1.
Observe caution before connecting any external device to the radio via its 44-pin I/O
connector. If an external device has its own DC power source/cable (i.e., if it is
powered separately from the radio), both the radio and the external device must be
properly grounded to the vehicle before connecting the two units together and before
making a positive (+) DC power connection to either unit. Otherwise, equipment
damage may occur.

P2, the cable’s 2-pin connector, provides connections for an external speaker in a front-mount radio
installation. For the respective installation information, see Section 9.1. P2 is not used in a remote-mount
radio installation, since the audio amplifier in the head drives the external speaker (speaker connection is
made at the rear of the control head).
P3, the cable’s 6-pin connector, is a connector for basic accessories (e.g., hookswitch, external relay with
back-EMF diode, etc.).
P4, the cable’s D-subminiature 25-pin connector, provides audio and data connections for optional
equipment such as an external siren and light system (e.g., Federal Signal SS2000 SmartSiren®), external
relay with back-EMF diode, etc.
P5, the cable’s D-subminiature 9-pin connector, provides NMEA-formatted GPS serial data connections
for the external computer processing the NMEA-formatted GPS data received by the radio’s internal GPS
receiver. See Section 12 on page 77 for additional information.

SIGNAL NAME TO/FROM DESCRIPTION
3 SDATA P4 pin 8
In a front-
mount radio installation, this pin for the siren/PA
interface is the siren serial data output (open-
collector/open-
drain) from the radio’s mounted (local)
control head
. It serially transfers siren and light control
data from the control head to a connected third-
party
siren and light system (e.g., Federal Signal SS2000
SmartSiren). Data rate = 1200
bps. Connects to
SS2000’s DB-9 pin 3. For a remote-mount radio installa-
tion, see footnote 4.
5 FDISC P4 pin 9
Buffered Filtered Discriminator Audio Output
(not
normally used). A fixed-level audio output with DC bias
.
Approximately 200 mV rms into a 600-
ohm load at rated
deviation. Does not
contain signaling (e.g., CTCSS).
Mutes when speaker mutes. Use a 33 µF / 50
V (or
greater) coupling capacitor to connect to a 600-
ohm load.
Use P4 pin 12 for ground.
13 ALO P4 pin 10 In a front-mount radio installation, this 600-ohm AC-
coupled differential audio output from the mounted (local)
control head is typically not used. In a remote-
mount
radio installation, these two pins of the radio’s DB-
44
connector are not functional.
12 MICHI P4 pin 11
1 EXTALO P4 pin 12
In a front-mount radio installation, VOLHI (a single-
ended
AC-coupled audio signal) and EXTALO
(signal ground)
provide public address (PA) mic audio from the mount
ed
(local) control head to a siren and light system,
such as
the Federal Signal SS2000 SmartSiren. Pin 13
connects
to SS2000’s DB-
9 pin 5. Pin 12 connects to SS2000’s
DB-9 pin 6. For a remote-mount radio installation,
these
two pins can provide an unmuted volume-level-
controlled
single-ended audio signal to external devices. P1 pin 1
(EXTALO) is over-
current protected on radio’s PK Board
by a 1-amp fuse.
