3 INTRODUCTION

This manual contains installation procedures for the XG-25M mobile radios and related options and

accessories. Procedures cover the mounting and cabling of the radio equipment, as well as basic in-

vehicle radio test procedures.

3.1 GENERAL DESCRIPTION

The XG-25M mobile radio is a high-performance digital mobile radio. Two different radios are available.

The 50-Watt VHF radio covers the 136 to 174 MHz VHF band and the 35-Watt dual-band radio covers

the 700 and 800 MHz bands. The radio can operate in Project 25 (P25) trunked, P25 conventional,

EDACS/ProVoice trunked, and analog conventional modes. The XG-25M is considered a front-mount

radio, since its control head is an integral part of the radio. The head cannot be mounted separately from

the radio.

FRONT VIEW

REAR VIEW

Figure 3-1: XG-25M Mobile Radio — Front and Rear Views

The XG-25M radio is designed to operate in a mobile environment, typically within a motor vehicle. It

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

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

radio, as listed in Table 4-3 (page 13), and in the XG-25M radio’s Product Safety Manual.

14221-1510-4440

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 radio.

The radio features a large text and graphics-based liquid-crystal display (LCD), and front panel controls

for user control of the radio.

The XG-25M 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. Specifications

are included in Section 2 of this manual.

The XG-25M may be equipped with an optional built-in Global Positioning System (GPS) tracking

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

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

the mobile transmit/receive antenna.

The XG-25M exceeds many tough environmental specifications included within military standard

MIL-STD-810G, the radio industry standard TIA/EIA-603, and the radio standard established by the U.S.

Forest Service.

The radio supports operation on APCO Project 25 compliant Common Air Interface (P25 CAI) radio

networks, and operation in a talk-around mode in accordance with the APCO Project 25. P25 radio

systems utilize Improved Multi-Band Excitation (IMBE) speech and data compression technology,

developed by Digital Voice Systems, Inc.

Harris recommends the buyer use only an authorized representative to install and

service this product. The warranties provided to the buyer under the terms of sale shall

be null and void if this product is installed or serviced improperly, and Harris will have

no further obligation to the buyer for any damage caused to the product or to any person

or personal property.

3.2 RADIO PROGRAMMING

Unless otherwise stated, all radio installation and test procedures presented in this manual assume the

radio has been programmed by radio network administration personnel before it is delivered to radio

installation personnel.

Radio Personality Manager (RPM) software application TQS3385 (part number SK-104768-001) is used

to program the XG-25M mobile radio for trunked radio systems. TQS3385 can also be used to program

the radio for analog conventional and P25 conventional operations. For additional information, refer to

RPM’s built-in online help and/or RPM Software Release Notes, publication number MS-012550-001.

Conventional RPM software application TQS3389 (part number SK-012177-001) is used to program the

XG-25M mobile radio for analog conventional and P25 conventional operations. Trunking mode

programming is disabled in TQS3389. For additional information, refer to RPM’s built-in online help

and/or Conventional RPM Software Release Notes, publication number MS-012761-001.

Both RPM applications can also be used to flash program new operating software (i.e., firmware) into an

XG-25M mobile radio. Refer to the radio’s maintenance manual for additional information.

Both RPM applications also support other radios such as the M7100, M7200, M7300, and Unity

XG-100M mobile radios, and the P7100, P7200, P7300, Unity XG-100P, XG-75 and XG-25P portable

radios.

RPM Release R9A or later is required for XG-25M mobile radio programming.

CAUTION

NOTE

14221-1510-4440

5.3 LOCATING COMPONENTS

Plan the mounting locations of all components (radio, 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, the Product Safety Manual, and other generally accepted professional radio installation

practices.

• The radio may be mounted below or above the vehicle’s dash, or at some other location per customer

requirements, available space, and/or mounting surface strength. Dimensions for the radio are listed

in Section 2.1 on page 6. 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.

• 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. Also, the front and sides of the

radio 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 cooling fins. The radio will automatically

reduce its transmit

RF output power when its ambient temperature exceeds

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

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

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

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

causing intermittent radio operation or complete radio failure.

CAUTION

14221-1510-4440

6 ANTENNA INSTALLATION

6.1 ANTENNA MOUNTING LOCATIONS

Review all Regulatory and Safety Information presented in the radio’s Product

Safety Manual. A transmitting antenna must be installed in accordance with the

guidelines presented in both the Product Safety Manual and this manual. The

Product Safety Manual is included in the radio eq

uipment package when the

package ships from the factory.

As a guide for determining the best possible mounting location in order to reduce human exposure to

radio frequency (RF) electromagnetic energy during transmit mode, refer to the following:

• For a 50-Watt VHF Radio: See Figure 6-1 (page 18)

• For a 35-Watt 700/800 MHz Radio: See Figure 6-2 (page 20)

Also refer to the respective Recommended Minimum Safe Lateral Distance table

presented in the Product Safety Manual. These tables list the recommended minimum

safe distance

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 power for mobile radios installed in a vehicle.

Antennas must be mounted in one of four (4) possible locations on the vehicle. Figure 6-1 and Figure 6-2

shows the recommended locations and antenna part numbers. Also, see Table 4-3 for additional

information. Always follow the antenna manufacturer’s instructions when mounting an antenna.

6.1.1 Direct Center or Center-Rear of Rooftop

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

following figures). 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 the following

figures).

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 the

following figures). In this case, an elevated-feed-point antenna is recommended. Although this type of

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

minimize human exposure to RF electromagnetic energy.

6.1.3 Rear Deck Lid for Stand-Alone GPS Receive Antenna

If the XG-25M mobile radio does not use a GPS combination-type antenna and it is equipped with a GPS

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

deck lid (location  in the following figures) is the recommended mounting location for this case. This

locates the GPS antenna inside the vehicle.

6.2.1 Installing NMO Antenna Mounts AN-125001-001 and 003

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

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

Section 6.2.1.3.

6.2.1.1 Standard NMO Antenna Mount AN-125001-001

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 NMO Antenna Mount AN-125001-003

This thick-roof NMO antenna mount uses either a ⅜-inch or a ¾-inch mounting hole in a relatively flat

area of the vehicle body, with a vehicle metal thickness of between 0.040 and 0.1875 inches (3/16-inch

maximum thickness).

For thick-roof NMO antenna mount AN-125001-003, using a ⅜-inch mounting hole

requires better access to the underside of the mounting location than if a ¾-inch hole is

used. This is because, in the case of a ⅜-inch hole, the antenna mount’s bushing

assembly must be inserted from the underside of the mounting surface.

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

AN-125001-003, the thickness of the mounting surface must be at least ⅛-inch

(0.125-inch minimum thickness

). This requirement is due to the thickness of the

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

6.2.1.3 Installation Procedure for Mounts AN-125001-001 and -003

1. Select the antenna mounting location in accordance with the information presented in Section 6.1 of

this manual. If necessary, contact the Technical Assistance Center for assistance. See page 11 for

TAC contact information.

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

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

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

obstruction or insufficient clearance, select another nearby mounting location.

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

mark from side-to-side of the vehicle.

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

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

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

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

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

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

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

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

diameter hole saws generally produce only shavings, not plugs.

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

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

the hole is evenly removed.

NOTE

14221-1510-4440

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

the lock nut.

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

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

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

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

6.2.2 Installing NMO Magnetic Antenna Mount AN-125001-007

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

removing all dust, dirt, etc.

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

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

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

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

perimeter gasket, etc., as necessary.

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

To remove a magnetic antenna mount, hold it at the bottom of its base and tilt it at an

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

Do not drag the mount across the mounting surface.

6.2.3 Installing All Other Antenna Mounts

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

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

6.2.4 Attaching NMO Antenna Elements

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

mount.

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

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

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

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

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

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

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

element from the antenna mount, and secure the element in a safe location inside the

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

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

re-installing the element.

5. Continue with the connection procedure presented in the next section.

6.2.5 Installing the Coax Cable and TNC RF Connector

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

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

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

possible chafing. Observe and follow this WARNING:

Do not cut an antenna cable any shorter than six (6) feet (1.83 meters), as measured

from the base of the antenna mount to the TNC connector that mates to the radio.

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

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

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

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

If the radio installation includes unity-gain antenna element part number AN-225006-

001, this element must be tuned (trimmed) for maximum performance (i.e., minimum

reflection) during the test procedures presented in Section 14. Other antennas used with

the radio are factory-tuned and therefore do not require tuning in the field.

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

If the XG-25M radio is equipped with the GPS receiver option, the GPS receiver requires connection to

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

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

it.

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

in the radio and if its functions will be utilized/required. Refer to Section 11 for

additional information.

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

mobile antenna. Refer to Table 4-3 (page 13) for available combo antennas.

NOTE

1. Before cutting the cable to a shorter length, refer to the previous

WARNING. Some antenna cables should never be cut, while others

can be cut to as short as 6 feet.

2. Trim the end of the cable to the dimensions shown at the left, taking

care not to nick the cable’s inner conductor or its braid/shield.

3. Slip the crimp sleeve over the end of the cable, with its flanged-end

facing towards the end of the cable.

4. Place the contact onto the cable’s inner conductor. The end of the

contact and the cable’s inner die

lectric must “butt square” together, as

shown to the left.

While holding the contact tight against the dielectric, crimp the contact

to the inner conductor using an appropriate crimp tool.

6. Flair the cable’s outer braid/shield and then gently but firmly push the

contact (and cable end) into the connector housing until a gentle snap

is felt, indicating the contact is locked in place.

7. Slip the crimp sleeve in place, butting its flanged-end against the

connector housing.

8. Using an appropriate crimp tool, crimp the crimp sleeve securely to

the cable end and connector housing. When crimping, hold the

housing and sleeve firmly together, and to the cable end.

6.2.6.1 General Installation Procedure

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

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

necessary, contact the Technical Assistance Center. See page 11 for TAC contact information. Do not

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

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

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

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

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

procedure presented later in this manual (i.e., procedure on page 45). The cable and its (male) SMA

connector must be protected from damage, dirt, and/or metal shavings which may be generated during

the mechanical and electrical installation of the radio. Temporarily tying the connector and cable-end

in a small plastic bag is recommended.

6.2.6.2 Installation Procedure for Inside-Rear-Deck Mounting in Ford Crown Vic

The following GPS antenna installation procedure is recommended for inside-rear-deck mounting of GPS

receive-only antennas, such as AN-025187-001 or AN-025187-003, in a Ford Crown Victoria. Other

vehicle makes/models may use similar installation scenarios:

1. Carefully remove the center rear

brake light assembly by removing

the screws on each side of the

assembly. Lift and set it aside.

2. Route the cable from the GPS

antenna through the rear deck,

next to the cable assembly for the

rear brake light.

3. Position the antenna near the rear glass.

For an antenna that is not a magnetic-

mount, secure it to the deck

near the rear glass in accordance with the instructions provided with

the GPS antenna.

4. Reassemble the rear deck brake light assembly while

using caution

to not to crimp/pinch the GPS coaxial cable.

A small relief notch

may need to be cut in the housing of the light assembly cable

passage.

The cable and its (male) SMA connector must be protected from damage, dirt, and/or metal shavings

which may be generated during the

mechanical and electrical installation of the radio. Temporarily

tying the connector and cable-end in a small plastic bag is recommended.

6. Route the cable to the area near where the radio will be installed.

Tie and stow the antenna cable as

necessary to pre

vent cable chafing or damage from moving items, like the trunk lid’s hinges and

springs. The antenna cable is connected to the radio’s SMA receptacle-

type (female) RF connector

per a procedure presented later in this manual (i.e., procedure on page 45).

Do not alter the length of cable from the GPS antenna. The SMA connector on the end

of the antenna cable is not field-replaceable.

NOTE

14221-1510-4440

7 RADIO INSTALLATION

7.1 MOUNTING THE RADIO

The Mounting Bracket Kit for the radio includes a heavy-gauge steel U-shaped mounting bracket. The

radio should be attached to a mounting surface using this bracket. The bracket can be mounted above or

below the radio. Kit contents are shown in Figure 7-2, and bracket dimensions are shown in Figure 7-3.

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

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

viewing angle, and a front-to-rear position offset. The radio has four (4) threaded mounting holes, two (2)

per side, and the mounting bracket has twelve (12) corresponding holes, six (6) per side. The radio must

be secured to the bracket using the four M5 socket-head screws included in the Mounting Bracket Kit (2

screws per side).

The radio is approximately front-to-rear centered within the bracket. 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 15 degrees. When positioned straight in the bracket, the radio extends

approximately 2 inches (5 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.

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

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

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

the minimum 16-gauge steel sheet metal requirement, the surface should be

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

using some other approved mounting method.

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

unreasonable vibration that could damage the radio, adversely affect transceiver

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

may experience degradation in the quality of voice and data communications.

WARNING

CAUTION

Figure 7-1: XG-25M Radio Dimensions

7.1.1 Mounting Bracket Installation

The radio’s mounting bracket is included with the Mounting Bracket Kit 14015-0201-01. Kit contents

are shown in Figure 7-2. This kit is Item 1 listed in Table 4-2 (page 12).

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 front panel.

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

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

bracket to the mounting surface. Four 1-inch-long #10-32 stainless-steel self-tapping screws are included

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.

Make any positional adjustments as necessary.

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

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

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

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

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

the bracket.

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

6. Using the bracket as a template, and/or the dimensional information shown in Figure 7-3, mark and

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

used.

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

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

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

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

deburr drilled holes before installing screws.

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

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

9. Set the bracket back into place.

10. Install and tighten the mounting screws/hardware.

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

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

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

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

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

the rear of the radio.

7.1.2 Inserting the Radio into the Mounting Bracket

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

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

(usually towards the rear of the vehicle).

2. Secure the radio to the bracket using the four (4) M5 x 10 mm stainless-steel socket-head screws, flat

washers, and lockwashers. Each screw should have a lockwasher against the screw head and a

flatwasher against the mounting bracket. This hardware is included with the Mounting Bracket Kit.

The kit’s contents are shown in Figure 7-2. The kit is Item 1 listed in Table 4-2 (page 12).

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

and the radio is firm and flush between the brackets.

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

area to secure and rest the excess cable lengths.

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

mounted radio may experience degradation in the quality of voice and data

communications.

7.2 DC POWER CABLE 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 for automatic

power-up/down to function properly.

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

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

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

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

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

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

properly.

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

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

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

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

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

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

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

battery terminal) via the supplied fuse.

NOTE

14221-1510-4440

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, two AGC-type fuses, and non-insulated ring

terminals. The following installation procedures are recommended:

7.2.2.1 Black Wire Connection (Ground Wire)

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

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

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

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

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

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

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

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

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

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

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

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

insulation back approximately ¼-inch.

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

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

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

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

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

the ring terminal.

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

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

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

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

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

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

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

diameter and install a small rubber grommet (not supplied) 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 co

mbination must also be sealed with a

silicon-based sealer before completing the installation.

Do not

install any wiring or fuse holder over or in the near vicinity of the vehicle’s

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

can lead to intermittent electrical connection to the battery.

CAUTION

14221-1510-4440

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

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

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

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

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

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

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

batteries.

Radio fuses should not be installed until all wiring is complete. This will prevent

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

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

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

3. Observe and follow the previously presented WARNING!

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

the main DC bus bar or stud).

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

(6) inches from the end.

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

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

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

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

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

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

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

(not supplied) may be used if required.

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

main/non-switched power distribution terminal block).

7.2.2.3 White Wire Connection

A review of the information presented in Section 7.2.1 (page 31) 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 automatically turns on and off with the vehicle’s ignition

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

sense input wire.” In this configuration, the white wire connects to a switched power source, typically

identified as “Accessory” power, that switches on and off with the vehicle’s ignition switch/key. When

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

up/down to function properly.

WARNING

14221-1510-4440

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

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

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

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

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

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

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

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

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

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

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

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.

7.2.2.3.2 Radio Turns On and Off with a Manual Switch

With this wiring configuration, the radio 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 for

automatic power-up/down to function properly.

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

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

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

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

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

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

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

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

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

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

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

terminal of the switch.

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

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

NOTE

14221-1510-4440

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.”

7.2.2.3.3 Radio Is “Hot Wired”

In the “hot-wired” configuration, the radio is turned on and off only by its on/off/volume control. 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.

14221-1510-4440

8 EXTERNAL SPEAKER INSTALLATION (OPTIONAL)

The XG-25M mobile radio has an internal (built-in) speaker on its front panel. This speaker’s audio

output power level is rated at 3 watts maximum. This speaker is driven by an audio amplifier located

inside the radio.

The radio has another audio amplifier in it. This amplifier can drive an optionally-installed external

speaker at up to 15 watts. When the external speaker is on/enabled, the radio’s internal speaker remains

off/disabled (muted).

If an external speaker is required, install it according to the below procedure. Total available cable length

for an external speaker 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.

This requirement assumes standard cabling is used.

1. Obtain Speaker LS102824V10. This speaker is rated for audio levels up to 20-watts.

2. Obtain Option Cable 14002-0174-08.

3. Select a location for the speaker that will allow for proper listening range with a moderate volume

setting.

4. Install the speaker using the hardware and mounting bracket supplied with it. Route the speaker cable

to the rear of the radio.

5. Connect the Option Cable to the DB-44 connector on the rear of the radio. Tighten the cable’s two (2)

jackscrews securely. See Section 10.1 for additional information on this cable.

6. Mate the Option Cable’s 2-pin connector (identified P2) to the 2-pin connector on the end of the

speaker cable. A mild click will be sensed to confirm proper mating.

7. Route the cables out of the way of casual contact. Tie and stow as necessary.

To support the external speaker, the radio must have the EXT SPKR (External Speaker)

9 MICROPHONE ATTACHMENT

Each microphone for an XG-25M radio has a 12-pin connector that mates with the mic connector on the

front panel of the radio. 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 radio and install the clip as follows:

1. Position the mic’s connector just in front of the radio’s mic connector so it can engage straight into

the mic connector. The small notch on the end of the mic’s connector must be positioned straight up

so it engages with the key in the connector of the radio.

2. Mate the two connectors by pressing them fully together. A click should be sensed when the

connectors latch together.

3. Using the microphone clip as a template, drill mounting holes in the surface of the selected location.

4. 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.

5. Clip the microphone to the clip.

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 before connecting the two units and before making a positive (+)

power connection to either unit. Otherwise, fuse(s) inside the radio may fail (open)

and/or other equipment damage could occur.

Connector P2 is the cable’s 2-pin connector that provided connections for an optional speaker.

Connection is not required if only the radio’s internal speaker will be used.

Connector P3, the cable’s 6-pin connector, is a connector for basic accessories (e.g., hookswitch, etc.).

Connector P4, the cable’s D-subminiature 25-pin connector, provides audio and data connections for

optional equipment.

Connector P5, a 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 11 on page 44 for additional information. This is serial port A of the radio.

Connector P6 provides a serial data interface used for radio programming. Like P5, this is a

D-subminiature 9-pin connector. This is serial port B of the radio.

11 GPS NMEA-FORMATTED DATA CONNECTION

To obtain GPS NMEA-formatted serial data from the radio, the radio must be equipped with the GPS

receiver option, and Option Cable 14002-0174-08 is required. For radios equipped with a GPS receiver,

follow this procedure to complete the GPS NMEA-formatted serial data connections:

1. Obtain Option Cable 14002-0174-08. Each “leg” of this cable is approximately 65 inches long (166

centimeters).

2. Connect the cable’s 44-pin D-subminiature (DB-44) male connector to the DB-44 female connector

on the rear panel of the radio. Tighten the two jackscrews with a small flathead screwdriver. Do not

over-tighten.

3. Connect the cable’s DB-9 female connector identified as P5 to the computer’s serial port DB-9 male

connector—either directly or extended via cable CA-013671-020 (a 20-foot-long cable); see Section

10.2. Tighten the screws firmly, and then route the cabling as required. If the computer is not

equipped with a DB-9 serial port connector, the use of a suitable adapter is required, such as

USB-to-RS-232 Adapter Cable CN24741-0001.

4. Follow the manufacturer’s instructions on processing the NMEA-formatted GPS data from the radio.

If the Option Cable 14002-0174-08 is not available, a 3-wire serial cable can be field-

fabricated. On the radio end, this cable must interface to the three GPS-related signals of

the radio’s 44-pin I/O Cable connector (pins 7, 31, and 32). See Table 10-1 for additional

information.

Industry software to process GPS information through this interface is not supported by Harris.

12 MOBILE DATA CONNECTION

If the radio installation must support mobile data communications of a computer running Mobile Data

Terminal (MDT) or similar software, follow this procedure to connect the computer to the radio:

1. Obtain Option Cable 14002-0174-08. Each “leg” of this cable is approximately 65 inches long (166

centimeters).

2. Connect the cable’s 44-pin D-subminiature (DB-44) male connector to the DB-44 female connector

on the rear panel of the radio. Tighten the two jackscrews with a small flathead screwdriver. Do not

over-tighten.

3. Route the “leg” of this cable that has the two DB connectors (i.e., DB-25 connector P4 and DB-9

connector P6) to the area near the serial port of the MDT computer. Protect the cable from possible

chafing and tie-and-stow it as necessary.

If the cable’s “leg” length is not long enough to reach the computer, obtain cable

CA-013671-020 (or equivalent) and use it to extend the connection from the DB-9

connector P6. Cable CA-013671-020 is a 20-foot-long standard DB-9 serial data cable.

4. Connect the female DB-9 connector to the computer. If the computer is not equipped with a DB-9

serial port connector, use a suitable adapter, such as USB-to-RS-232 Adapter Cable CN24741-0001.

Before data communications can occur on a P25 system, the respective data option must

be enabled. Contact the Technical Assistance Center (TAC) for additional information.

TAC contact information is included on page 11.

NOTE

14221-1510-4440

13 INITIAL POWER-UP TEST

1. At the radio’s main waterproof (HFB-type) fuse holder installed near the vehicle battery, insert the

15-amp fuse that was included with the radio’s DC Power Cable.

2. Tie and stow all fuse holders at this location to prevent excess vibration/movement.

3. Carefully reconnect the vehicle’s battery ground cable.

4. If not already, temporarily connect the mobile antenna cable from the vehicle-mounted mobile

antenna to the female TNC RF connector on the rear panel of the radio. This is a temporary

connection until test procedures in Section 14 are complete.

5. If the radio is equipped with the GPS receiver option, permanently connect the antenna cable from the

GPS antenna (or mobile/GPS combo antenna) to the female SMA connector on the rear panel of the

radio. The male SMA connector on most GPS antenna cables has a 5/16-inch hex collar, so the use of a

wrench of this same size is normally required for tightening. However, some may have collars with

only knurled surfaces, so a standard wrench or torque wrench cannot be used. In either case, do not

over tighten the connector and do not twist the cable when tightening.

6. If the installation is wired so the vehicle’s ignition key/switch turns the radio on and off, turn the

switch to the Accessory or Run position.

7. If the radio is not already powered up, do so by rotating its on/off/volume control clockwise out of the

detent position.

8. Verify the radio has powered-up by observing its display. If the display is not functioning, refer to

Section 7.2.1 as necessary.

As long as the software configuration parameters have been loaded, successful installation is almost

immediately realized:

• After a short boot-up sequence, the radio displays login information and/or a talk group.

• If no errors are displayed, the installation is most-likely properly wired.

• If an error is displayed, recheck all cable connections, verify all fuses are properly installed, and

verify battery power on the load side of the fuses, etc. If problems persist, contact the Technical

Assistance Center (see page 11).

• Consult the Operator’s Manual for operational information.

Refer to Section 14 for performance test information.

14221-1510-4440

14 PERFORMANCE TESTS

This section includes procedures to verify the performance of the installation’s mobile antenna system.

There are three (3) procedures in this section:

• Changing Operating Mode for Tests

• Testing by Transmitting into a Dummy Load (a 50-Ohm RF Terminator)

• Testing by Transmitting into the Mobile Antenna

The accuracy of test results depends upon a DC power source in the range of 13.6 volts

DC ±10%. The current capacity of the power source must be greater than 15 amps.

Make sure the vehicle’s battery is fully charged by running the engine for a few

minutes before the test, and keep the engine running during the test procedures. Abide

by the following WARNING!

If the vehicle’s engine must remain running, the vehicle location should be well

ventilated so exhaust fumes from the engine do not cause harm!

If a vehicle equipped with this radio requires jump-starting, the radio installation’s

main fuse should be removed from the holder prior to jump-starting. Doing so will

prevent damage to the radio system.

Prior to installation, the radio’s power level should be configured appropriately. The

wide range of power levels indicated in the following procedures takes into account

such things as: customer’s requirements; measurement errors, especially to include

uncalibrated equipment; cabling losses; and voltage and temperature variations. By no

means should the result from Performance Testing in this section be construed as the

exact value of power level output from the radio, as the value is set and more

accurately measured in the factory. The values obtained in these test procedures

determine a successful installation only.

9. If the wattmeter reading is within the range, record the measured value in the appropriate space on

the data collection form near the end of this manual.

If the wattmeter reading is outside the range, verify the radio’s power supply voltage (i.e., battery

voltage) is within the specified range, recheck all connections, and measure the RF output power

again. If this fails to produce a reading within the range, replace it and repeat this procedure. If

problems persist, contact the Technical Assistance Center (see page 11).

14.3 TRANSMITTING INTO THE MOBILE ANTENNA

1. Connect the antenna cable from the vehicle-mounted antenna to the wattmeter as shown in Figure

14-1.

2. If not already, turn the radio on and set it to the required operating mode (based upon available radio

programming and test equipment).

3. Set the radio to a test talk group or conventional channel, if available.

It is recommended that a test talk group/channel be allocated for this testing.

Otherwise, interference with other radio users in the system may occur. Also, during

transmissions, always observe the RF exposure-

related safety information

presented in XG-25M radio’s Product Safety Manual.

4. Position the wattmeter’s element to measure forward RF output power. Rotate it if necessary. The

arrow on the face of the element must point away from the radio and towards the antenna for forward

power measurements.

5. Set the wattmeter to measure average RF power.

6. Key the radio’s transmitter via the microphone’s PTT button.

7. Verify the measured transmit output power is within the respective range listed in Table 14-2. The

respective power setting listed in this table assumes the radio is currently configured at the maximum

transmit power level.

Transmit only for as long as needed to take the measurement, then immediately

disable the transmission.

8. If the wattmeter reading is within the range, record the value in the appropriate space on the data

collection form near the end of this manual.

If the wattmeter reading is outside the range, verify the radio’s power supply voltage (i.e., battery

voltage) is within the specified range, recheck all connections, and measure the forward power again.

If the installation employs a ¼-wave unity-gain antenna, observe the following NOTE. If these

checks/corrections fail to produce a reading within the range, check all cabling and connections and

repeat the testing procedure to this point. In the event the wattmeter reading still falls outside the

range, replace the antenna, make sure all connections are seated firmly, and repeat the testing

procedure. If problems persist, contact the Technical Assistance Center (see page 11).

If the radio installation employs a ¼-wave unity-gain antenna (part number AN-

225006-001

), the driven element (i.e., whip) of the antenna must be trimmed to the

proper length in order to minimize antenna system VSWR. Refer to the instructions

included with the antenna for trimming instructions.

NOTE

14221-1510-4440

9. Position the wattmeter’s element to measure reverse (reflected) RF power from the antenna. The

arrow on the face of the element must point away from the antenna and to the radio to measure

reverse power.

10. Key the radio’s transmitter via the microphone’s PTT button.

11. Compare the wattmeter reading with the RF power output range of 2 watts or less.

Transmit only for as long as needed to take the measurement, then immediately disable

the transmission.

12. If the wattmeter reading is within the range, record the value in the appropriate space on the data

collection form near the end of this manual.

If the wattmeter reading is outside the range, make sure the antenna is consistent with the specified

frequency range of the radio. Recheck all antenna connections, and measure the reverse power again.

If the installation employs a ¼-wave unity-gain antenna, observe the NOTE that immediately follows

step 8. If these checks/corrections fail to produce a reading within the range, replace the antenna and

repeat the entire antenna test procedure. Any value exceeding the maximum allowable reflected

power value will result in a diminished RF output signal. If problems persist, contact the Technical

Assistance Center (see page 11).

13. Disconnect the coaxial cable jumper and wattmeter.

14. Permanently connect the cable from the vehicle-mounted antenna to the radio’s antenna cable by

mating the two TNC connectors together. Use two pairs of soft-jaw pliers to gently tighten this

connection. Do not over tighten and do not twist either cable.

15. Make several test calls on the radio system to verify operation of the mobile radio. Before making the

calls, select other talk groups or conventional channels, as required to verify operation.

To prevent RF leakage and ensure peak performance, make sure the RF connectors are

tight, but do not over-tighten so connector damage will not occur.

Improper installation of the RF cables may

lead not only to poor radio

performance but also to harmful exposure to RF electromagnetic energy.

Testing is complete. The radio is now ready for normal communications.

Double-check the following items before considering the installation completed:

• Verify all newly installed mechanical hardware is mounted securely and all respective mounting

hardware is tight.

• Verify all electrical interconnections are connected properly and the associated connector attachment

hardware is tight. Pay special attention to all RF antenna cables!

• Verify all related fuses are correctly installed and properly rated.

• Verify all electrical cables and wiring are tied, stowed, and protected so they are out of the way of

casual contact, away from sources of extreme heat, and wire chafing cannot occur. Pay special

attention to all RF antenna cables!

• To prevent fumes from entering the vehicle’s passenger compartment, seal the hole/grommet/wire

combination at the firewall with a silicon-based sealer.

• Verify all vehicle components are properly reinstalled such as kick panels, headliners, and seats.

• If the installation includes a separately-mounted on/off power switch for manually turning the radio

(and possibly other systems) on and off, verify it is labelled accordingly. For example: “Radio

ON/OFF.”

• Remove all tools and unused hardware from the vehicle.

• Verify the test performance data has been recorded on the data collection form shown in this manual.

from this warranty but are warranted under a separate Rechargeable Battery Warranty (ECR-7048).

B. Seller’s obligations set forth in Paragraph C below shall apply only to failures to meet the above

warranties occurring within the following periods of time from date of sale to the Buyer and are

C. If any Equipment fails to meet the foregoing warranties, Seller shall correct the failure at its option (i)

by repairing any defective or damaged part or parts thereof, (ii) by making available at Seller’s factory

any necessary repaired or replacement parts, or (iii) by replacing the failed Equipment with equivalent

new or refurbished Equipment. Any repaired or replacement part furnished hereunder shall be

warranted for the remainder of the warranty period of the Equipment in which it is installed. Where

such failure cannot be corrected by Seller’s reasonable efforts, the parties will negotiate an equitable

adjustment in price. Labor to perform warranty service will be provided at no charge during the

warranty period only for the Equipment covered under Paragraph B.3, B.4 and B.5. To be eligible for

no-charge labor, service must be performed at Seller’s factory, by an Authorized Service Center

(ASC) or other Servicer approved for these purposes either at its place of business during normal

business hours, for mobile or personal equipment, or at the Buyer’s location, for fixed location

equipment. Service on fixed location equipment more than thirty (30) miles (48 km) from the Service

Center or other approved Servicer’s place of business will include a charge for transportation.

D. Seller’s obligations under Paragraph C shall not apply to any Equipment, or part thereof, which (i) has

been modified or otherwise altered other than pursuant to Seller’s written instructions or written

approval or, (ii) is normally consumed in operation or, (iii) has a normal life inherently shorter than the

warranty periods specified in Paragraph B, or (iv) is not properly stored, installed, used, maintained or

repaired, or, (v) has been subjected to any other kind of misuse or detrimental exposure, or has been

involved in an accident.

E. The preceding paragraphs set forth the exclusive remedies for claims based upon defects in or

nonconformity of the Equipment, whether the claim is in contract, warranty, tort (including

negligence), strict liability or otherwise, and however instituted. Upon the expiration of the warranty

period, all such liability shall terminate. The foregoing warranties are exclusive and in lieu of all other

warranties, whether oral, written, expressed, implied or statutory. NO IMPLIED OR STATUTORY

WARRANTIES OF MERCHANTABILITY OR FITNESS FOR PARTICULAR PURPOSE SHALL

APPLY. IN NO EVENT SHALL THE SELLER BE LIABLE FOR ANY INCIDENTAL,

CONSEQUENTIAL, SPECIAL, INDIRECT OR EXEMPLARY DAMAGES.

This warranty applies only within the United States.
