For details on these configurations, see Section 2.2.2 on page 2-8.
1.3
Base/Control Stations
If mobile radio equipment is installed at a fixed location and operated as a control station or as a
fixed unit, the antenna installation must comply with the following requirements in order to ensure
optimal performance and compliance with the RF energy exposure limits in the standards and
guidelines listed in the 68P81095C99 manual:
• The antenna should be mounted outside the building on the roof or a tower if at all possible.
• As with all fixed site antenna installations, it is the responsibility of the licensee to manage the
site in accordance with applicable regulatory requirements and may require additional compliance actions such as site survey measurements, signage, and site access restrictions in order
to ensure that exposure limits are not exceeded.

2.1
Planning the Installation
The XPR 4300/4350/4500/4550 radio operates only in negative ground electrical systems. Before
starting the radio installation, make sure that the ground polarity of the vehicle is correct. Accidentally
reversing the polarity will not damage the radio, but will cause the cable fuses to blow.
Planning is the key to fast, easy radio installation. Before starting the installation, inspect the vehicle
and determine how and where you intend to mount the antenna, radio, and accessories. Plan wire
and cable runs to provide maximum protection from inching, crushing, and overheating.
CAUTION
2.1.1
Before installing any electrical equipment, check the vehicle manufacturer’s user manual.
The installation of this device should be completed by an authorized servicer or installer.
Installation Examples
Your mobile two-way radio offers various methods of installation, including dash or remote mount.
Except for 110W radios, all versions of the XPR 4300/4350/4500/4550 can be either dash or remote
mounted (see Figure 2-1 through Figure 2-2).

Caution
CAUTION: DO NOT mount the radio on a plastic dashboard
without first reinforcing the dashboard; the weight of the radio may
crack or break the dashboard.
CAUTION: DO NOT mount the radio on a flat or concave surface
where the radio could be partially submersed in water. This is
especially important if the cab area of the vehicle is cleaned by
spraying with water. If the radio sits in water for a length of time,
moisture may seep inside the radio and damage the electronic
components.
CAUTION: DO NOT allow water to stand in recessed areas of
vertically mounted radios. Remove any moisture immediately to
prevent it from seeping down into the radio.
The mounting location must be accessible and visible. Select a location that will permit routing the
RF antenna cable as directly as possible.
NOTE: For new or existing installations, use one of the following mounting kits GLN7342B (Low
profile mounting bracket), GLN7324B (High profile mounting bracket), RLN4799B (Key Lock
mounting bracket) or RLN5999A ( Dim Mounting Bracket). Orient the mounting trunnion as

Dash Mount with Trunnion
1. Select the location to mount your radio on the transmission hump (see Figure 2-6) or under
the dash (see Figure 2-7). When mounting the trunnion on the transmission hump take care
the transmission housing is not affected.
2. Using the trunnion mounting bracket as a template, mark the positions of the holes on the
mounting surface. Use the innermost four holes for a curved mounting surface such as the
transmission hump, and the four outmost holes for a flat surface such as under the dash.
3. Center punch the spots you have marked and realign the trunnion in position.
4. Secure the trunnion mounting bracket with the four self-drilling screws provided (see
Figure 2-6 and Figure 2-7).
5. Ensure that the plastic guides are aligned (horizontal) to the grooves of the trunnion. Slide the
radio into the grooves until it snaps into place (see Figure 2-6). Secure the radio with the two
wing screws provided.

Standard Configurations: Ignition Sense Cable
Ignition Sense Cable
Motorola supplies an ignition sense cable and recommends that it be used with every mobile
installation. The ignition sense cable allows the radio to be turned on and off with the vehicle ignition
switch, and allows the radio to “remember” the state of the radio on/off switch, even if it is changed
while the vehicle is off.
• For radio ON/OFF control independent of the ignition switch, connect the red ignition cable (yellow for remote) (pin 25 of accessory connector) to “battery hot” at the vehicle fuse block (dash
mount only).
• For radio ON/OFF control via the ignition switch, connect the red ignition cable (yellow for
remote) to “ignition” at the fuse block.
Note that for remote mount installations, the red and yellow leads are connected, not the red lead
from the rear of the radio.
The ignition sense cable uses either a 3-amp (P/N 6580283E01) or 4-amp (P/N 6580283E02) fuse.
For other considerations when connecting the ignition cable, see the Basic Service Manual
(Motorola publication part number 6881096C73).

Antenna Installation
IMPORTANT NOTE: To assure optimum performance and compliance with RF Energy Safety
standards, these antenna installation guidelines and instructions are
limited to metal-body vehicles with appropriate ground planes and take
into account the potential exposure of back seat passengers and
bystanders outside the vehicle.
NOTE: For mobile radios with rated power of 7 watts or less, the only installation restrictions are to
use only Motorola approved antennas and install the antenna externally on metal body
vehicles. For mobile radios with rated power greater than 7 Watts, always adhere to all the
guidelines and restrictions in section 2.5.1 below.
2.5.1
Selecting an Antenna Site/Location on a Metal Body Vehicle
1. External installation – Check the requirements of the antenna supplier and install the
vehicle antenna external to a metal body vehicle in accordance with those requirements.
2. Roof top – For optimum performance and compliance with RF Energy Safety standards,
mount the antenna in the center area of the roof.
3. Trunk lid – On some vehicles with clearly defined, flat trunk lids, the antennas of some radio
models (see restrictions below) can also be mounted on the center area of the trunk lid. For
vehicles without clearly defined, flat trunk lids (such as hatchback autos, sport uitility vehicles,
and pick-up trucks), mount the antenna in the center area of the roof.
Before installing an antenna on the trunk lid,
- Be sure that the distance from the antenna location on the trunk lid will be at least 85 cm
(33 inches) from the front surface of the rear seat-back to assure compliance with RF
Energy Safety standards.
- Ensure that the trunk lid is grounded by connecting grounding straps between the trunk lid
and the vehicle chassis.
IF THESE CONDITIONS CANNOT BE SATISFIED, THEN MOUNT THE ANTENNA ON
THE ROOF TOP!

Standard Configurations: Antenna Installation
2-9
4. Mounting restrictions for certain radio models
For 40 Watt UHF models, the 1/4 wave antenna should be mounted only in the center
area of the roof, not on the trunk lid, to assure compliance with RF Energy Safety
standards.
5. Ensure that the antenna cable can be easily routed to the radio. Route the antenna cable as
far away as possible from any vehicle electronic control units and associated wiring.
6. Check the antenna location for any electrical interference.
7. Ensure that any other mobile radio antenna on this vehicle is at least one foot (30.48 cm)
away from this antenna.
NOTE: Any two metal pieces rubbing against each other (such as seat springs, shift levers,
trunk and hood lids, exhaust pipes, etc.) in close proximity to the antenna can cause
severe receiver interference.
2.5.2
Mini-UHF Connection
To ensure a secure connection of an antenna cable's mini-UHF plug to a radio's mini-UHF jack, their
interlocking features must be properly engaged. If they are not properly engaged, the system will
loosen. Using a tool (pliers or wrench) will not overcome a poor engagement, and is not
recommended.
NOTE: Applying excessive force with a tool can cause damage to the antenna or the connector (e.g.,
stripping threads, deforming the collar or connector, or causing the connector to twist in the
housing opening and break).
The mini-UHF connector tool (Motorola part number HLN6695_) is designed to securely tighten the
antenna plug–radio jack connection without damaging either the plug or the jack.
Motorola recommends the following sequence to ensure proper attachment of the system (see
Figure 2-30):
Coax Conductor
Plug (Pin)
Collar Pulled

Figure 2-30. Mini-UHF Connection (as shown on mid-power)
1. Make sure that there is sufficient slack in the antenna cable.
2. Make sure that the collar of the antenna cable plug is loose and does not bind.
3. Make sure that the mini-UHF jack is tight in the radio housing.
4. Slide the collar back against the flange. Insert the antenna cable plug’s pin fully into the radio
jack, but do not engage the threads.
5. Ensure that the plug’s and jack’s interlocking features are fully seated. Check this by grasping
the crimp on the cable jack, rotating the cable, and noting any movement. If the features are
seated correctly, there should be NO movement.
6. Finger-tighten the antenna cable plug’s collar onto the radio’s jack.

7. Give a final tug, by hand, to the collar, and retighten by hand as firmly as possible.
8. Slip the mini-UHF connector tool over the coaxial cable, using the gap between the tool’s legs
(see Figure 2-31). Then, slide the tool up onto the plug’s knurled collar. Squeeze the two
straight legs of the tool firmly together between your thumb and index finger and turn
clockwise (as shown) to tighten the collar. It should take 1/4 turn or less. When you feel the
tool slipping on the collar, the connection has been properly tightened. The tool can also be
used to loosen a tight collar.
NOTE: DO NOT use pliers or any other device to grip the tightening tool. It has been designed to
allow you to achieve the proper torque on the collar without overtightening. Overtightening the
collar can damage the connector and the radio.

Caution
CAUTION: DO NOT ground the radio's speaker leads. This system
has a floating speaker output (dc voltage on both leads); damage
to the audio circuit will result if either lead is grounded or if they are
shorted together.
The speaker kit includes a trunnion bracket that allows the speaker to be mounted in a variety of
ways. With the trunnion bracket, the speaker can mount permanently on the dashboard or in
accessible firewall areas. The trunnion allows the speaker to tilt for best operation. Mount the
speaker out of the way so that it will not be kicked or knocked around by the vehicle occupants.
Mount the speaker as follows:
1. Use the speaker mounting bracket as a template to mark the mounting hole locations.
2. Use the self-drilling screws provided to fasten the trunnion.
3. Attach the speaker and fasten to the trunnion with two wing screws.
4. Route the speaker wires under the carpet or floor covering, or behind the kick panels. Be sure
the wires are out of the way and will not be snagged and broken by the occupants of the
vehicle.

This pin must be connected to ground by jumper on accessory cable if emergency is disabled, even if disabled by
CPS. If enabled, this line must be grounded via a switch, which is normally closed. The emergency debounce time
is programmable via CPS.
Pulling this line to ground will activate PTT function, activating the AUX_MIC input.
Fixed level (independent of volume level) received audio signal, including alert tones. Flat or de-emphasis are programmed by CPS. Output voltage is approximately 100 mVrms per 1kHz of deviation. The DC offset is 1.4V.
This output is used to detect when a rear microphone accessory is taken off-hook, to override PL to alert the user
to busy traffic prior to transmitting.
This microphone signal is independent of the microphone signal on the front microphone connector. The nominal
input level is 80mVrms for 60% deviation when used for motorcycle, but can also support 300 mVrms for future
APCO accessories. The DC impedance is 660 ohms and the AC impedance is 560 ohms.
See Table 2-1 in Chapter 2 for wiring options.
Note: Please see the XPR 4300/4350/4500/4550 Basic Service manual (Motorola publication part number
6816816H01) for more detailed descriptions of these pins.
