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 invehicle radio tests.
3.1
GENERAL DESCRIPTION
The XG-25M mobile radio is a high-performance digital mobile radio. It can operate in Project 25 (P25)
trunked, P25 conventional, EDACS/ProVoice trunked, and analog conventional modes. The radio is
available in three (3) different RF bands as follows:
•
136 to 174 MHz 50-Watt VHF radio;
•
378 to 470 MHz 50-Watt UHF radio; and,
•
700/800 MHz 35-Watt dual-band radio.
The XG-25M is typically installed in a front-mount configuration; see Figure 3-1 below. However, an
optional field-applied remote-mount kit is available that supports a remote-mount radio configuration.
This is accomplished via separation of the control head from the radio using remote interface hardware
and a 30-foot cable included in the kit; see Figure 3-2.

FRONT VIEW
Figure 3-2: Remote-Mount XG-25M Mobile Radio (With Optional Remote-Mount Kit Applied)
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 4-4 (page 15).
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. In the remote-mount application, the control head does not
require its own DC operation power source; it receives DC operating power from the radio via the remote
control cable.
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 Phase 1
radio systems utilize Improved Multi-Band Excitation® (IMBE) speech and data compression technology.
P25 Phase 2 radio systems utilize Advanced Multi-Band Excitation Plus 2® (AMBE+2®) speech and data
compression technology. Both of these compression technologies were developed by Digital Voice
Systems, Inc.

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. Programming instructions are beyond the scope of this manual.
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-75P and XG-25P portable
radios.
RPM Release R9A or later is required to program the VHF radio.
RPM Release R11A or later is required to program the UHF radio.
NOTE
RPM Release R10A or later is required to program the 700/800 MHz radio.
The XG-25M mobile radio can be programmed via a serial port at the 44-pin connector on the rear panel
of the radio or via a serial port at the front panel microphone connector. Programming instructions are
beyond the scope of this manual.
For programming via the rear panel serial port, Option Cable 14002-0174-08 must be used to connect the
radio’s rear panel 44-pin connector to the computer with RPM. A 9-pin DB-style connector of the Option
Cable is used for connection to the computer’s serial port.
For programming via the mic connector serial port, Front Panel Programming Cable 14015-0200-01 must
be used to connect the radio’s mic connector to a serial port of the computer with RPM. The 9-pin DBstyle connector of the Option Cable is used for connection to the computer’s serial port.
NOTE
Programming via the mic connector’s serial port using Front Panel Programming
Cable has certain limitations! Refer to Section 11.3 on page 55 for additional
information.

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.
18
•
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 front-mount 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.
•
For a remote-mount radio installation, the radio is typically located in the motor vehicle’s trunk, or
some other preferably unoccupied section in a vehicle, such as a fire truck’s equipment shelf. The
control head is typically located under the vehicle’s dash panel. Dimensions for the radio, control
head, and hand-held controller are listed in Section 2.1 on page 6. 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. 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.
CAUTION
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).
CAUTION
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.

ANTENNA INSTALLATION
6.1
ANTENNA MOUNTING LOCATIONS
WARNING
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 equipment 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 20)
•
For a 50-Watt UHF Radio: See Figure 6-2 (page 22)
•
For a 35-Watt 700/800 MHz Radio: See Figure 6-3 (page 24)
NOTE
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 6-3
shows the recommended locations and antenna part numbers. Also, see Table 4-4 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.

ANTENNA INSTALLATION PROCEDURES
An antenna must be installed before completing the radio installation.
NOTE
Table 4-4 (page 15), Figure 6-1 and Figure 6-3 list the mobile radio antennas available for use with the
respective 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 NMO Antenna Mounts AN-125001-001, -002, -003 and -004
These NMO style antenna mounts can each be used with several different antenna elements. Only limited
access under the mounting location is typically required. The installation procedure is presented in
Section 6.2.1.3.
6.2.1.1
Standard NMO Antenna Mounts AN-125001-001 and AN-125001-002
This These standard ¾-inch NMO antenna mounts 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. AN-125001-002 has a
very-low-loss coax cable (LMR/RF-195 or equivalent).
6.2.1.2
Thick-Roof NMO Antenna Mounts AN-125001-003 and AN-125001-004
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). AN-125001-004 has a very-low-loss coax cable (LMR/RF-195 or equivalent).
NOTE
6.2.1.3
For thick-roof NMO antenna mount AN-125001-003 or AN-125001-004, 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 or AN-125001-004, the thickness of the mounting surface must be at
least ⅛-inch (0.125-inch minimum thickness). This requirement is due to the thickness
of the alignment ring used to center the bushing assembly within the ¾-inch mounting
hole.
Installation Procedure for Mounts AN-125001-001 through -004
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 12 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.
25
14221-1510-4440, Rev. B
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.
CAUTION
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 6-4 and Figure 6-5, 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 Mounts AN-125001-007 and
AN-125001-008
1. Thoroughly clean the bottom of the magnetic mount and the selected vehicle mounting surface by
removing all dust, dirt, etc.
2. Carefully place the magnet mount onto the metal surface of the vehicle at the selected location. The
coax cable exiting the mount’s base should be orientated towards the point at which it will enter into
the interior of the vehicle. Do not try to reposition it by sliding it on a painted metal surface.
3. Route the mount’s coax cable to the radio location, passing it by the trunk lid’s perimeter gasket, door
perimeter gasket, etc., as necessary.
4. Install the antenna element per the procedure in Section 6.2.4.
27
14221-1510-4440, Rev. B
CAUTION
6.2.3
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.
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 6-4 or Figure 6-5) around
the mount and against the surface of the vehicle. If a lubricant or sealant was included with the
gasket, apply it to the gasket before placing the gasket.
3. Apply the antenna element to the top of the mount and tighten it in a clock-wise direction (as viewing
from the top). Use an appropriate wrench if required. Do not over-tighten.
4. Install a placard (not supplied) on the vehicle’s dash panel, in accordance with the following
CAUTION. Place the placard in plain view of the vehicle operator’s position.
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.
CAUTION
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.
WARNING
2. Using an appropriate crimp tool, crimp the supplied TNC RF connector to the end of the antenna
cable. For crimping instructions, see Figure 6-6 or the instructions supplied with antenna mount.
3. The antenna cable is connected to the radio’s TNC receptacle-type (female) RF connector per a
procedure presented later in this manual. The cable and its TNC connector must be protected from
damage, dirt, and/or metal shavings which may be generated during the mechanical and electrical
installation of the radio. Temporarily tying the connector and cable-end within a small plastic bag is
recommended.

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.
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.
Slip the crimp sleeve over the end of the cable, with its flanged-end
facing towards the end of the cable.
Place the contact onto the cable’s inner conductor. The end of the
contact and the cable’s inner dielectric 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.
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.
Slip the crimp sleeve in place, butting its flanged-end against the
connector housing.
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.

passage.
5. 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 prevent 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 58).
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.

RADIO INSTALLATION
7.1
MOUNTING THE RADIO
7.1.1
General Information
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 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 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 approximately 15 degrees maximum. 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.
•
Front-Mount Radio: For a front-mount radio installation, the design allows a front-to-rear tilting of
the radio within the bracket for the best viewing angle, and a front-to-rear position offset. Typically,
either titling, or offset, or both, may be applied to a front-mount radio installation to position the
front-mount radio for best operator viewing and control access.
•
Remote-Mount Radio: For a remote-mount radio installation, the radio bracket tilt and the offset
design are generally not put to use, as neither would be necessary. The radio is simply centered within
the bracket and parallel with the mounting surface.
NOTE
The optional CH-25 Remote-Control Conversion Kit includes a mounting bracket for
the control head. That bracket allows the head’s tilt to be adjusted for best operator
viewing and control access. Control head installation procedures are included in
Section 8 that begins on page 43.
Observe the follow with respect to clearances at the front of the radio:
•
Front-Mount Radio: For a front-mount radio, 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.
•
Remote-Mount Radio: For a remote-mount radio, the area directly at the front of the radio must
have clearance for the installation and removal of the Remote Control Cable. At least 6 inches (15.2
centimeters) of space is recommended.
The radio’s 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).
33
14221-1510-4440, Rev. B
WARNING
CAUTION
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.

7.1.2
Remote-Mount Radio Installations Only: Application of the CH-25
Remote-Control Conversion Kit
For a remote-mount radio installation, the CH-25 Remote-Control Conversion Kit must be applied to the
existing front-mount radio, to convert it to a remote-mount radio with a separate control head. To
accomplish this, complete the procedures presented in the kit’s Product Manual, publication number
14221-1510-4450. That manual is included with the kit.
Instructions included in Product Manual 14221-1510-4450 include procedures on updating the radio and
control head software/firmware if necessary. The manual also includes instructions on removing the
control head from the existing front-mount radio, attaching the radio’s remote interface to the front of the
radio thus converting it to a remote-mount radio, and attaching the control head’s remote interface to the
back of the control head.
After completing the conversion, continue with the radio’s mounting bracket installation.
7.1.3
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 13).
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, for a
front-mount radio, 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. For a remote-mount radio, clearance at the
front of the radio must be sufficient for removal and attachment of the Remote Control Cable.
As shown 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
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.
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.
CAUTION
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.

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 13).
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.
NOTE
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.

DC POWER CABLE INSTALLATION
7.2.1
Overview of On/Off Power Wiring Configurations
The following power wiring configurations are supported:
•
Radio and control head turn 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 and control head. 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 and control head turn on and off with a manual switch — This configuration is used when,
for example, the radio and control head have 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 and control head turn on with its on/off/volume control (“hot wired”) — This
configuration allows radio and control head on/off power control only via its on/off/volume control. It
may be desired if, for example, the radio and head have 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.
NOTE
Unlike some remote-mount mobile radio installations, a remote-mount XG-25M radio
installation’s control head does not require its own DC power cable and fuse (i.e.,
separate from the radio). The head receives DC operating power from the radio via the
Remote Control Cable.
In all of the above listed 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, 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.
38
14221-1510-4440, Rev. B
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.
NOTE
CAUTION
CAUTION
Remote-Mount Radio — In a typical vehicle installation of a remote-mount radio, as a
time-saving measure, the majority of the length of the Remote Control Cable between
the remote-mount radio and the control head can be simultaneously routed together with
the red and white wires of the radio’s DC Power Cable. Also, the Option Cable from the
back of the radio can also be simultaneously routed with most of the length of these two
wires and the Remote Control Cable. Detailed installation procedures for the Remote
Control Cable are included in Section 8.5 which begins on page 45.
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 combination must also be sealed with a
silicon-based sealer before completing the installation.
Do not install any wiring or fuse holder over or in the near vicinity of the vehicle’s
engine. Excessive engine heat can cause permanent damage to these components and
can lead to intermittent electrical connection to the battery.
39
14221-1510-4440, Rev. B
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.
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 38) 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 and Control Head Turn On and Off with Vehicle’s Ignition Switch/Key
With this wiring configuration, the radio and 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 for automatic
power-up/down to function properly.
40
14221-1510-4440, Rev. B
NOTE
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 and Control Head Turn On and Off with a Manual Switch
With this wiring configuration, the radio and control head are manually turned on and off via an on/off
switch mounted separately from the radio and head, not through the vehicle’s ignition switch/key. This
configuration is used when, for example, the radio/control head 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.
41
14221-1510-4440, Rev. B
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 and Control Head are “Hot Wired”
In the “hot-wired” configuration, the radio and control head are turned on and off only by the head’s
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.
42
14221-1510-4440, Rev. B
CH-25 REMOTE CONTROL HEAD INSTALLATION
Procedures in this section must be performed only for a remote-mount radio installation.
NOTE
8.1
For a front-mount radio installation, advance to Section 9 or 10 now.
APPLICATION OF THE REMOTE-CONTROL CONVERSION KIT
Before beginning vehicle installation of the CH-25 control head, the CH-25 Remote-Control Conversion
Kit must be applied to the front-mount radio to convert it to a remote-mount radio with a separate control
head. To accomplish this, complete the procedures presented in the kit’s Product Manual, publication
number 14221-1510-4450.
Instructions included in that manual include procedures on removing the control head from the existing
front-mount radio, attaching the radio’s remote interface to the front of the radio thus converting it to a
remote-mount radio, and attaching the control head’s remote interface to the back of the control head.
8.2
REFLASHING THE RADIO (IF REQUIRED)
CAUTION
8.3
It is critical that the correct minimum version of firmware is loaded into the front-mount
XG-25M mobile radio prior to starting the physical conversion/separation process. A
remote-mount XG-25M will not recognize the remote-control CH-25 head and the two
will be completely non-functional with an older firmware version. Refer to Product
Manual publication number 14221-1510-4450 for complete details. That manual is
included with CH-25 Remote-Control Conversion Kit DM-ZN9Z
INSTALLING THE REMOTE-MOUNT RADIO
After completing the procedures in Product Manual 14221-1510-4450, install the remote-mount radio
into its mounting bracket by following the procedure in Section 7.1.4 (page 37).
Also connect/re-connect the 3-pin connector of the DC Power Cable to the 3-pin power connector on the
rear of the radio. The respective cable installation procedure are included in Section 7.2 (page 38).
8.4
CONTROL HEAD MECHANICAL INSTALLATION
After the CH-25 Remote-Control Conversion Kit is applied and the radio is installed into its mounting
bracket, continue by installing the control head, as described in the following subsections:
8.4.1
Selecting the Mounting Location
When selecting a location for the control head, first review and observe the safety and operatorconvenience related information presented in Section 5.1 on page 17. 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 connector of the Remote Control Cable’s that mates to the connector on the
rear panel of the head. The control head can be mounted in, under, or on top of a mounting surface
(typically the vehicle’s dash) as space permits.
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. It must not
vibrate when the vehicle is in motion and it must remain stable during normal operations by a radio
operator (i.e., button presses, knob rotation, excessive tugs on the mic cord, etc.). If the control head is
43
14221-1510-4440, Rev. B
mounted to a plastic or similar-type dash panel, either fender washers or a field-fabricated metal backing
plate should be utilized on the opposite side of the panel from the bracket.
8.4.2
Installing the Mounting Bracket and Control Head
Follow this procedure to mechanically install the control head’s mounting bracket and attach the head to
it:
1. Obtain the mounting bracket from the conversion kit. The bracket is illustrated in Table 4-3 on page
14. Also, Figure 8-1 on page 44 shows the bracket and a remote-mount control head.
NOTE
The control head can be attached above its mounting surface, like on the top of a dash
panel. In that case, the bracket is located below the head, as shown in Figure 8-1.
Alternately, the head can be attached below its mounting surface, such as underneath a
dash panel. In that case, the bracket is located above the head.

Figure 8-1: Control Head Mounting Bracket (shown positioned below head)
2. Using the mounting bracket as a template, mark and drill mounting holes into the mounting surface as
required. When positioning the bracket, note that the chamfered edge-slots on each end of the bracket
must face in the same direction as the control head’s display will need to face. In a typical vehicle
installation, this is towards the rear of the vehicle.
CAUTION
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.
3. If necessary, deburr the newly drilled holes.

4. Set the bracket back on the mounting surface, positioning it so its chamfered edge-slots are facing in
the same direction as the head’s display will need to face.
5. 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.
6. 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. Bracket
attachment must survive all expected radio operator actions such as hard button-press actions and
excessive tugs on the mic cord.
7. Install the control head into the bracket by sliding the short pegs protruding from the left and right
sides of the head into the chamfered edge-slots on each end of the bracket.
8. At each end of the bracket, start a socket-head cap (Allen) head screw with a flat washer by inserting
the screw (with washer) through the arched hole in the bracket and then into the threaded hole in the
side of the control head. This hardware is included with the Mounting Bracket Kit. Start both screws,
with one washer each. Turn each screw in clockwise direction to start it into the threaded hole.
9. Tilt the head in the bracket to the required angle for best viewing by the operator at his/her normal
position, and then fully tighten both screws using a 4-millimeter hex key (Allen) wrench.
Recommended torque is 8.7 inch-pounds (10 kgf-cm). Do not over-tighten.
CAUTION
8.5
Each cap screw should not be installed/re-used more than eight (8) times, because
thread locking strength may suffer after this number of re-installations. Replace the cap
screws with new cap screws if their locking strength is in question and/or after
exceeding eight (8) installations.
INSTALLING THE REMOTE CONTROL CABLE
Follow this procedure to install the Remote Control Cable:
1. Obtain Remote Control Cable 14015-0203-31. The cable is included in CH-25 Remote-Control
Conversion Kit DM-ZN9Z. It is 30 feet (9.1 meters) long.
2. Connect one of the Remote Control Cable’s 44-pin connector to the 44-pin connector on the front of
the radio. Before connecting either connector, note the following:
As illustrated in Figure 8-2, the cable of the Remote Control Cable exits each D-shaped connector of
the cable in opposite directions with respect to the D shape of each connector. At one connector, it
exits to the right and at the other connector, it exits to the left (assuming the D-shapes are orientated
in the same direction as shown in the figure). Also, from an electrical stand-point, both connectors
have identical pin-outs.
As shown in Figure 8-3 on page 46, this allows the Remote Control Cable to be reversed
(radio<>head) to reverse the left/right orientation of the cable in relation to the left/right sides of the
radio and head. This may be advantageous for some installations where, for example, cable clearances
are tight on one side of the radio and/or head, or cable routing and service loop routing benefits from
one direction over another.
Be sure to leave a service loop in the cable so when radio removal is necessary, movement will not be
unnecessarily limited.

3. Route the cable through the vehicle’s interior to near the location of the control head. Remove interior
panels, door kick panels, etc., and route the cable through existing channels in the vehicle body as
necessary.
4. Connect the other 44-pin connector of the Remote Control Cable to the 44-pin connector on the rear
panel of the control head. Tighten the jackscrews securely, but do not over-tighten them. Be sure to
leave a service loop in the cable so when control head removal is necessary, movement will not be
unnecessarily limited.
5. Tie and stow all excess cable length so it will be out of casual contact with vehicle occupants. Be sure
to protect it from wire chafe where necessary.
6. Re-install all previously removed interior panels, door kick panels, etc.
47
14221-1510-4440, Rev. B
EXTERNAL SPEAKER INSTALLATION (OPTIONAL)
The XG-25M mobile radio has an internal (built-in) speaker in the front panel of the control head. This
speaker’s audio output power level is rated at 3 watts maximum. It is driven by an audio amplifier located
inside the radio.
The radio has another internal speaker audio amplifier. 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 11.1 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.
NOTE
48
To support the external speaker, the radio must have the EXT SPKR (External Speaker)
function programmed to a radio button and/or menu. With this programming, the
external speaker can be toggled on and off by pressing the button programmed with this
function, or by selecting the function on a menu. When the external speaker is on, the
radio’s internal speaker remains off/disabled.
14221-1510-4440, Rev. B
10 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’s 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 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
need to be grounded.
5. Clip the microphone to the clip.

CAUTION
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 12 on page 57 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.

12 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
11.2. 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.
NOTE
If the Option Cable 14002-0174-08 is not available, a 3-wire serial cable can be fieldfabricated. 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 11-1 for additional
information.
Industry software to process GPS information through this interface is not supported by Harris.
13 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).
NOTE
If the MDT requires a Clear-To-Send (CTS) and/or a Ready-To-Send (RTS) handshake
lines, use Option Cable 14002-0174-08 Rev. A or later. Earlier cables did not have the
CTS and RTS interconnections to connector P6 of the cable.
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.
NOTE
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.
57
14221-1510-4440, Rev. B
4. Connect the female DB-9 connector (P6) 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.
NOTE
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 12.
14 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 15 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 12).
•
Consult the Operator’s Manual for operational information.
Refer to Section 15 for performance test information.
58
14221-1510-4440, Rev. B
15 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
CAUTION
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!
WARNING
CAUTION
NOTE
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 power level output from the radio, as the level is set and more accurately
measured in the factory. The levels obtained in these test procedures determine a

The 700/800 MHz XG-25M radio is aligned for a maximum transmit power of 35 watts
across the entire 700/800 MHz frequency band. However, FCC licensed systems, verify
the radio’s 700 MHz channels are limited to 30 Watts or per license requirements via the
radio’s personality programming.
The UHF XG-25M radio is aligned for a maximum transmit power of 50 watts across its
entire 378 - 470 MHz operating band. However, for equipment operating in accordance
with FCC 47CFR80 rules (i.e., Maritime Services), it is the responsibility of the licensee to
ensure the radio is installed and aligned per license requirements.
61
14221-1510-4440, Rev. B
Transmit only for as long as needed to take the measurement, then immediately disable the
transmission.
NOTE
10. If the wattmeter reading is within that range, record the measured level in the appropriate space on
the data collection form near the end of this manual.
If the wattmeter reading is outside that 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 12).
15.3 TRANSMITTING INTO THE MOBILE ANTENNA
1. Turn off the radio.
2. Connect the antenna cable from the vehicle-mounted antenna to the wattmeter as shown in Figure
15-1.
3. Turn on the radio and set it to the required operating mode (based upon available radio programming
and test equipment).
4. Set the radio to a test conventional channel that is approximately in the middle frequency range of the
radio installation’s antenna element.
NOTE
It is recommended that a test conventional 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.
5. 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.
6. Set the wattmeter to measure average RF power.
7. Key the radio’s transmitter via the microphone’s PTT button.
8. Verify the measured transmit output power is within the respective range listed in Table 15-2. 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.
NOTE
9. If the wattmeter reading is within the range, record the level 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
62
14221-1510-4440, Rev. B
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 12).
NOTE
If the radio installation employs a ¼-wave unity-gain antenna (part number AN225006-001), 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.
10. 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.
11. Key the radio’s transmitter via the microphone’s PTT button.
12. For a good mobile radio installation, an antenna system VSWR of between 1.2:1 and 1.5:1 is
reasonable. If the utilized wattmeter/power-meter cannot directly measure and display VSWR, use the
following formula to calculate the reverse power at a 1.5:1 VSWR level:
Preflected (Watts) = Pforward (Watts) * 0.04, where Pforward (Watts) is the measured forward power.
For example: For a Pforward of 30 Watts, Preflected = 30 * 0.04 = 1.2 Watts. See Table 15-3 for
more examples.

13. If the wattmeter reading is within the range, record the value in the appropriate space on the TEST
PERFORMANCE DATA FORM on page 67, and then advance to the next step in this procedure.
Notes for Troubleshooting Bad VSWR/Reverse Power Readings:
 Make sure the installed antenna element is consistent with the specified frequency range of
the radio by checking the antenna element’s datasheet VSWR spec, etc.
 Verify the NMO antenna base is properly installed and tight on the NMO antenna mount.
 Verify the antenna element is properly installed and tight on the NMO antenna base. Some
elements use a small set screw in the base to secure the element to the base.
 Ensure field-dressed coax cables are properly crimped, including the coax center conductor to
the connector pin, and the coax shield to the connector’s body.
 At the radio’s antenna port connector, verify the antenna coax cable’s RF connector is
tightened in accordance with manufacturer’s guidelines.
 Expect more losses depending on the cable length and RF frequency.
 Expect more reflected power, if measurement is made inside a metallic structure.
 Consider overall measurement accuracy/errors.
 Recheck all antenna connections, and measure the reverse power again. For example: If the
installation employs a ¼-wave unity-gain antenna, observe the NOTE that immediately
follows step 9. 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.
 It is understandable that the user may not have a full control over the test environment. If this
is the case, and after the above recheck the readings are still outside the expected range, use
the following alternative method to ensure the installation is done correctly.
1. Measure the output RF power of the radio directly from the radio.
2. Connect the antenna cable to the radio.
3. Remove the radio installation’s antenna element from the mount (base) and using a
suitable NMO adapter so the antenna mount can be connected to the wattmeter/power
meter.
4. Measure the RF power at the antenna mount.
5. Use the cable loss data in Table 15-4 to calculate the approximate cable losses. After
all losses are accounted for, measurements should be within ±1 dB of the original
output RF power measurement.

 If problems persist, contact the Technical Assistance Center (see page 12).
14. Disconnect the coaxial cable jumper and wattmeter.
15. 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.
16. 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.
NOTE
Improper installation of the RF cables may lead not only to poor radio
performance but also to harmful exposure to RF electromagnetic energy.
WARNING
Testing is complete. The radio is now ready for normal communications.
