Chapter 1 Introduction
This manual covers the installation procedures for ASTRO APX mobile and motorcycle radios with
O2, O3, O5, O7 and O9 control heads, and accessories required to complete the radio system. The
radio system consists of a control head, radio, antenna, microphone, speaker, cabling, Universal
Relay Controller (URC), and accessories.

Mobile Radio Description
1.1.1
Dimensions
Figure 1-1, Figure 1-2, Figure 1-3 and Figure 1-4 show the basic dimensions of the dash mount
transceiver trunnion APX mobile radio. The transceiver portion of a remote mount APX mobile is
sized similarly.
When installing the radio, make sure to plan the installation carefully and leave additional room in the
rear of the radio for cabling and accessory connections; in the front of the radio for access, controls,
and cabling (if remote mount); and to the sides of the radio so that you may access and install the
trunnion screws/wing screws.
NOTE: The measurement unit used in Figure 1-1 to Figure 1-22 is millimeter.

NOTE: The dash mount configuration is not applicable for 100W radios and O9 control heads.
There are two versions of the APX mobile dash mount. The first are the O2, O5 and O7 control
heads which are mounted on the front of the transceiver housing. The second is the O3 control head
which is connected to the transceiver via a coiled cable, which is plugged into the CAN connector on
the transceiver.
Electrical connection between the two takes place within the radio via a flexible circuit board
between the connectors on the front of the transceiver and at the back of the control head for O2, O5
and O7 and between the connectors on the front of the transceiver and at the back of the TIB for the
O3.

Remote Mount Configuration
In the remote control version, the transceiver and the control head are mounted separately in the
vehicle. The O2, O5 and O7 control heads are mounted in remote trunnions near the operator.The
O3 and O9 control heads are also mounted near the operator using extension cables. The
transceiver and control head are mounted using a trunnion or other mounting hardware. If the
transceiver is located in a car trunk, ensure that it is mounted securely and that sufficient cooling is
provided. Do not cover the transceiver with baggage, blankets, etc.
NOTE: The keypad mic should only be plugged into the Modified Modular Plug (MMP) connector
located on the control head, in either dash mount or remote mount configuration.

Planning the Installation
The APX mobile radio operates only in negative ground electrical systems with a valid operating
range of 10.8VDC to 16.3VDC. 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
Before installing any electrical equipment, check the vehicle manufacturer’s user
manual for warnings or recommendations.
The installation of this device should be completed by an authorized servicer or
installer. Failure to properly install the device may result in damage to the device, or
improper operation.

Radio Operation Wiring for Dash and Remote Configurations
Determine from Table 2-1, Table 2-2, or Table 2-3 the radio functionality you wish to achieve, which is
controlled by the vehicle’s ignition switch state, the physical wiring of the radio’s ignition sense (ACC)
wire, and by the programmed CPS setting. For additional radio functionality as determined by the
programming of the ignition switch in CPS, refer to the HELP menu in your CPS (i.e. Ignition as:
Required, Blank, Soft Power Off, TX Inhibit, PTT TX Inhibit, Ignition Only Power Up).
Choose a clean ignition point which is not shared in the immediate vicinity by other high current
accessories/devices. This will help to reduce the transients on the ignition line. Examples of 
high-current accessories/devices are: Air Horn, relays, lightbars and etc. It is recommended to wire
to the vehicle’s ACC line, not the START or the solenoid side of the ignition circuit. Refer to chapter 6
for best installation practices. The Ignition sense (ACC) cable uses either a 3-amp fuse
(6580283E01) or 4-amp fuse (6580283E02).
2.1.3.1 Dash Mount: Power, Ignition, and Emergency Cable Installation
The standard dash mount rear ignition sense cable HLN6863 contains a “thin red” ignition wire, a
jumper wire that shorts emergency to ground, and two gray wires attached to an external speaker
plug. The thin RED wire is the ignition sensed wire. Refer to Table 2-1, Table 2-2, or Table 2-3 for its
correct wiring configurations.
NOTE: This cable MUST be attached in order for the radio to operate in Dash mount, regardless of
how emergency is programmed in CPS or wired inside the vehicle. Either the emergency
jumper wire or an emergency accessory (footswitch or button) must be wired to the rear of the
transceiver in Dash mount. Otherwise, upon attachment of the radio’s power cable to the
vehicle battery, the radio will incorrectly determine that emergency operation has been
activated, such as when an emergency footswitch is de-pressed and the emergency pin is
ungrounded.
6878215A01
Standard Configurations Planning the Installation
2-15
2.1.3.2 Remote Mount: Power, Ignition, and Emergency Cable Installation
The single control head O2, O5, O7 or O9 remote mount configurations receive power from the J200
connector’s red and black wires. The yellow wire at J200 is one ignition sense wire. On mid power
radios, the J2 and J600 connectors can also be used for ignition sense. On high power radios, the
J200 yellow wire or the J600 connector can be used for ignition sense. If the HLN6863 is attached at
J100 of the O2, O5, O7 or O9 control head, the “thin red” wire will NOT function as an ignition sense
wire, since the J100 connector has no ignition sense electrical connection.
NOTE: It is incorrect for installation to attach ignition sense at more than one wire or connector. 
Refer to Table 2-1 or Table 2-2 for its correct wiring configurations.
The O3 control head receives its power down the CAN cable, and detects the ignition state by the
ignition sense pin at either J2 or J600. On mid power radios, the J2 and J600 connectors can also be
used for ignition sense. On high power radios, only the J600 connector can be used for ignition
sense.
In Multi-Control Head installations, the yellow ignition wire must be connected to the head assigned
ID # 1. See Section 2.2.2.5 “Setting the Initial Control Head ID” on page 2-29 for further information.
In remote mount O2, O3, O5, O7 or O9, an Emergency jumper to ground is placed by default on the
TIB (JU344) so that there is no need to attach a cable with an emergency accessory at either J2 or at
J600. This jumper must be removed if an emergency accessory (footswitch or button to Ground) is
installed at either J2 or J600 (or J626 on the accessory cable) locations. If the jumper JU344 is
removed but no emergency accessory is installed, the radio will power-up incorrectly into emergency
mode all the time. Refer to Figure 4-3 for details.
The design of the control head is different compared to the transceiver, therefore it is also NOT
necessary to attach HLN6863 at J100 to prevent accidental emergency operation. The control head
uses an edge-detect, not a state-detect like on the transceiver, so mounting of HLN6863 is not
mandatory.

Standard Configurations Planning the Installation
Siren/PA Configuration/Programming
The Siren/PA is shipped pre-wired for 100W operation. It can be rewired for 65W, 75W, or 130W
power levels.
To change to another power level, perform the following:
1. Open the Siren/PA connector cover to gain access to the two-connector speaker leads. Do
not change the speaker common lead (pin 20). The other lead is connected to pin 35 (for
100W operation).
2. Using an appropriate pin removal tool, extract pin 35 and move it to one of the following pin
locations:
- pin location 36 for 75W operation
- pin location 28 for 65W or 130W operation
3. For 65W or 75W operation, no further changes are required. Reassemble the connector.
4. For 130W operation, you must parallel two 11 speakers, each rated at 65W minimum.
Proper phasing of the two speakers is important--when connecting two speakers in parallel,
wire similar speaker terminals together to ensure maximum loudness and prevent
"deadspots." For example, if the terminals are marked "1" and "2", connect the terminals
marked "1" together and connect those wires to one speaker lead. Connect the terminals
marked "2" together and connect those wires to the other speaker lead.
Caution
Before continuing, remember that under a high-line supply condition
(16.6V), up to 30% more power will go to the speaker(s) after
reconfiguring for 130W operation. Do this only when your PA
speakers are capable of handling the extra power.
5. When the Siren/PA is configured for dual speaker, 130W operation, it is necessary to remove
a resistor and move two jumpers to set the correct power level. Remove the Siren/PA cover,
and locate resistor R219 (0 ohm). This resistor should be removed for 130W operation.
Locate jumpers JU100 and JU101. These jumpers should be installed for 130W operation.
6. Close and reconnect the Siren/PA connector cover.
NOTE: Jumpers JU100 and JU101 do not affect the Siren output level. JU100 and JU101
compensate for the lower speaker load and the two speakers in parallel, by
decreasing the gain U102-1. JU100 affects the radio PA level and JU101 affects the
PA audio level.

Radio Mounting
Caution
DO NOT mount the radio on a plastic mounting surface without first reinforcing the
mounting surface; the weight of the radio may crack or break the mounting surface.
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.
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.
Care must be taken to shield the control head (front and back) from direct exposure to
pressurized water. The pressurized water from a hose, in most cases, is more severe
than the stated test and conditions in typical environments.
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 optimum radio performance, orient the mounting trunnion as shown in Figure 2-22 or
Figure 2-23 for mid power and Figure 2-24 for high power. For new or existing installations of
all but 100W radios, use only the APX mobile trunnion, kit number HLN7002_except for APX
2500 and APX 4500 which shall use the trunnion with kit number HLN6861_. For new or
existing installations of 100W radios, use only the APX mobile trunnion, kit numbers
HLN7003_.

4. After the trunnion has been mounted in the vehicle using the screws provided, install the
radio. Place the radio with the lock handle fully opened on the trunnion, oriented at least
10 mm in front of the rear catches. Push the radio towards the rear catches. The radio is lifted
up slightly and then drops back down, flushed with the trunnion, and stops against the rear
catches. Once this occurs, close the lock handle. Rotate the handle towards the top of the
radio until it is locked in place. The key is not needed in the lock to close the handle, but is
needed to reopen. The keys can only be removed from the lock when it is in the locked

An adjustable trunnion, which allows a number of mounting positions, is supplied for mounting the
control unit. The installation must not interfere with the operation of the vehicle or its accessories, nor
disturb passenger seating or leg room. The control head must be within convenient reach and
viewing of the user.
If the trunnion is mounted on a plastic mounting surface, all four mounting screws should penetrate
the mounting surface’s supporting metal frame. If that is not possible, use a metal backing plate (not
supplied) to strengthen the installation. Install the control follows:
1. Use the control unit trunnion as a template to mark the mounting holes; drill 5/32" holes. 
If mounting on a plastic surface, use a metal backing plate.
2. Attach the trunnion bracket using all four 10-16" x 5/8" self-tapping screws provided.
3. Temporarily install the control head (adjusting for proper viewing angle) and fasten it to the

Antenna Installation
IMPORTANT:
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 tuned power greater than 7 watts, always adhere to all the
guidelines and restrictions in Section 2.4.1 below.
2.4.1
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, sports utility
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.
Caution
4. Mounting restrictions for certain radio models.
For all VHF and 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.
6878215A01
Standard Configurations Antenna Installation
2-39
7. Ensure that any transmitting radio antennas on this vehicle are separated from each other by
at least 3 feet (0.9 meter). See Figure 2-49.
8. The minimum distance between the antenna and the radio/accessories should be at least 
3 feet (91.44 cm).
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.

Standard Configurations Antenna Installation
Mini-UHF Connection
To help aid in the installation of the radio antenna(s), there are labels indicating the frequency. The
first is on the FCC label at the top of the radio which calls out the frequency and by using arrow
points, which side the RF connector of the frequency is located at the back of the radio. The second
is located at the back of the radio, next to the RF connector(s) (see Figure 2-50). 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 2-50 and Figure 2-51):

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 2-52). 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.

GPS Antenna Placement
The GPS antenna (excluding the Motorcycle GPS antenna) must be placed at least, 3 feet 
(0.9 meters) away from any transmitting antenna, and the antenna must have a clear, unobstructed
view of the sky for best performance. The length of the cabling must be taken into consideration
before the installation is started.
2.4.4
GPS Connection
To ensure a secure connection of the GPS antenna cable's SMA plug to a radio's SMA jack, the
connector must be fully seated. If the connectors are not fully seated, the system will loosen. This
should be done by hand to ensure excess force is not applied. GPS positions as shown in 
Figure 2-54 and Figure 2-55 are located in different positions. The mid power radio has the GPS
antenna connector on the back of the radio while the 100W radio has the antenna connector on the
front of the radio.
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).

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 mounting surface 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

Standard or O3 Control Head Hang-Up Clip
The hang-up clip must be within reach of the operator(s) and close enough to the control head to
prevent cable strain. Measure this distance before actually mounting the bracket. Since the bracket
has a positive-detent action, the microphone can be mounted in any position.
Use the hang-up clip as a template to locate the mounting holes. To avoid interference when
removing the microphone, install the flathead screw in the top clip hole.
Some microphone models require the grounding of the microphone clip in order for HUB operation to
work correctly. Refer to the documentation that comes with your Motorola microphone model.
NOTE: For multi-control head configuration where only one of the control heads has a microphone,
the control heads without a microphone attached must have their HUB or Monitor pin
(J100-22) jumpered by a wire to GND (J100-1 or J100-14) for HUB operation to work.

RFID Reading
To read an RFID tag using a UHF Gen 2 RFID reader (e.g. Motorola’s MC9090-G), open an
appropriate RFID read application, point the RFID reader at the tag and activate the reader's RFID
antenna (e.g. pull Motorola’s MC9090-G scanning trigger). RFID reader must be within 1 foot from
tag in order to read.
Two variables, Read Angle and Reader Orientation, aid in the distance needed to read and write to
the RFID Tag. Read distance is independent of Tag Angle, but the reader should be as close to
perpendicular to the tag as possible (Read Angle).
As Read Angle increases past 60 degrees, read distance will begin to decrease; tag will become
unreadable once Read Angle exceeds 90 degrees (see Figure 2-64 and Figure 2-66). RFID tag
cannot be read through metal. The orientation of the reader (Reader Orientation) and the tag must
be aligned to improve read and writability (see Figure 2-70).

Chapter 3 Universal Relay Controller Installation
The Universal Relay Controller (URC) is an extension of and an orderable accessory for O7 or O9
control head. URC is used to control high power switching peripherals, e.g. lightbar. URC works on
all lightbars which can be controlled by power application. URC is connected to the transceiver's
GCAI port.
The URC design consists of a microcontroller and uses 10 relays to control the switching device. A
separate ground for isolation exists between the relay and MCU sections, which is provided by the
use of iCoupler from Analog Devices. Each relay is connected to an output with 15 A fuse. The
maximum load allowed on each output is 12 A. Two cables, each with the maximum of 60 A, can be
used to connect to the input connector at the bus bar. Each cable is connected with a 60 A circuit
breaker. One-wire EEPROM is employed to enable GCAI to recognize the URC accessory ID. CPS
can be used to program the relay patterns.
When installing URC, make sure to plan the installation carefully and leave additional room in the
front and rear of the box for cabling and accessory connections; and also to the sides of the radio so
that you may access and install the trunnion screws.
The recommended mounting location for URC is in the car trunk, either next to the transceiver or
within the area not further than 4.5 m away from the transceiver. Ensure that sufficient cooling is
provided. Do not cover URC with baggage, blankets, etc.
Do not backfeed power into URC.
Caution
3.1
Universal Relay Controller Mounting
The mounting location must be accessible and visible. Select a location that permits routing the
cable as directly as possible.
NOTE: For optimum URC performance, orient the mounting trunnion as shown in Figure 3-1.
Figure 3-1. Universal Relay Controller Orientation
An adjustable trunnion, which allows a number of mounting positions, is supplied for mounting the
URC. The installation must not interfere with the operation of the vehicle or its accessories.

OD range of cable is 2 mm to 4 mm) that is able to withstand 5 A. The ground cables (A+) are
not supplied.
NOTE: The ground is used to switch the relays, and not act as a ground to the actual device being
controlled.
2. The loose end of the ground cable with cable strip length 7.94 mm (5/16”) is then connected
to a two-pin terminal block. Both pins on the terminal block are inter-connected and either pin
can be used. The cap nut is then reassembled with tightening torque 7 lb-in.

Wires
1. Assemble the wires into the lightbar gasket retainer and lightbar gasket. The URC can
support lightbars through control wires with outer diameter ranging from 
1.52 mm to 3.77 mm (0.06” to 0.148”), with wire gages ranging from AWG 12 – 20.
2. Each individual loose wire (prior to stripping off the wire jacket) needs to be inserted one at a
time through the chassis. Ensure the lightbar wire is straight before inserting the wire into the
chassis. Each wire is sealed individually by the radial gasket seal. When a thick wire (i.e.
AWG 14 wire or wire OD > 2.90 mm) is inserted through the chassis, there is potential torn at
the rubber gasket. Remove the rubber gasket residual and continue to the next step.
3. Thin wires 2.5 mm and below should be dressed into the retention feature using a black stick
(see Figure 3-5); thick wires above 2.5 mm should be routed above the retention feature.
Strip off the wire until 7.94 mm (5/16”) after the wire is inserted into the URC, and install the
wire into respective lightbar terminal block.
4. Cover the lightbar gasket retainer's hole with seal, gasket and ground cable gland, if no wire
is inserted.

5. The lightbar gasket should be replaced at each reassembly of the wire.
NOTE: Use of other cable gages except as recommended in this manual may result in water
intrusion. Any reassembly of wire needs a new lightbar gasket replaced. If the current loading
for one wire is higher than 12 A, the wires should be splitted before being assembled to the
URC system. Wires kit (PMKN4109_) is provided to ease installation of the URC. Incorrect
use of the wires kit, e.g. improper connection at external loose end wires, may impact the
robustness of the URC.
Remove the wires and gasket residual inside the URC after the wire installation, before
closing the top housing of the URC.
3.2.4
O7/O9 to URC Cable
The O7/O9 to URC cable (Motorola part number 3064153H02) can be assembled either before or
after reassembling the top housing. Assemble the RJ45 port of the cable into the RJ45 connector on
the URC and turn the locking collar instead of cable, 90 degrees to the right to ensure it is locked
properly. After that, test whether the cable is locked properly or not by trying to pull out the cable.

Emergency Pushbutton or Footswitch Installation
Mount the switch using the hardware that comes with the kit. Connect the button/switch wires to a
ground pin and the emergency pin, removing the default jumper wire in the rear accessory cable.
The button/switch will short the pins when in-active. When the button/switch is pressed, its contact
opens, the emergency path is un-ungrounded and pulled-high inside the radio transceiver, and
detected by the processor. If an emergency accessory is used at either (or both) J2 connector and
J626 connector, all jumper wires, shorting emergency to ground, must be removed so button/switch
press can be detected.
In additional to removing the default jumper wires in accessory cables, you must also remove a
jumper part on the printed circuit board of the TIB, in order for the button/switch to be detected. On
the TIB PCB (both mid power and high power use the same TIB) a zero-ohm jumper is placed by
default so that the radio does not go into emergency when no cable is attached at either J2 or J626
in remote mount configuration. This jumper part, JU344, must be removed if either or both J2 and
J626 will have any type of emergency cable and button/switch attached. Otherwise, the processor
will never see emergency become un-grounded.

USB Data Cables
It is recommended that the USB 1.5 meter data cable HKN6163_ is used for both dash mount
configurations (at J2 connector) and for remote mount configurations (at J100 connector). This is
because the HKN6163_ has the emergency jumper present, which is necessary for correct dash
mount configurations. For interfacing at the MMP port, use Cable HKN6184_ which is a USB device
cable.
The USB 4 meter (15 feet) data cable enable HKN6172_ is recommended for remote mount
configurations only (at J100).
If the customer intends to use the HKN6172_ for dash mount configurations (at J2), the cable’s 
26-pin connector must be opened and an emergency jumper-wire placed across pins 14 and 15.
Refer to Figure 4-1.

The VIP output pins are on the back of the control head (J100 and J400), or the rear accessory port
(J2), as shown in Figure 2-10, Figure 4-12 and Figure 4-13, respectively. Use these connections to
wire control relays. One end of the relay should connect to switched B+ voltage, while the other side
connects to a software controlled ON/OFF switch inside the control head. The relay can be normally
on or normally off depending on the configuration of the VIP outputs. There are three VIP output
connections, as follows:

The function of these VIP outputs can be field programmed in the control head. Typical applications
for VIP outputs are external horn/lights alarm and horn ring transfer relay control. For further
information on VIP outputs, see the control head programming manual.
VIP OUT 1 and VIP OUT 2 can be accessed from either J100 or J400 connectors. This is to allow a
previously wired VIP OUT at J2 to move easily to J100. However, when any cable is inserted into
J400, J100 VIP OUTs are disabled.
When installing relays to the VIP OUT lines, a diode is necessary to prevent damage to the transistor
or MOSFET, due to “back EMF” when the field collapses on the relay coil. Some vendor relays
already come with this diode built-in, and other relays require the customer to install it. Figure 4-8
shows the proper placement of the diode across the relay coil. The transistor or MOSFET is located
inside the radio or the D.E.K. box.

Note:
To 'activate' a VIPOUT, you have to ground the VIPOUT, such that the
current now flows thru the relay coil to GND through a MOSFET inside
the radio or control head, which causes the relay wiper to toggle. The
MOSFET of a VIPOUT should never be used to directly drive an
accessory. The MOSFET should be used to control an external relay.

isolators. A large, braided ground-strap (installed between the mounting plate bolts and the
motorcycle frame) grounds the transceiver.
5.1.2
Control/Display Unit
All radio functions, except push-to-talk (PTT), are activated from the control head, which also is
weather-resistant. The control head and the external speaker are mounted for easy access near the
center of the handlebars. The control head is positioned for unobstructed viewing, and it may be
tilted on the horizontal axis for ease of viewing. The microphone cable port on the front of the control
head is plugged and is not used.

Motorcycle Radio Installation Motorcycle Radio Description
5.1.3
Control Head Cable
The control-head cable connects the control head to the transceiver. The cable is routed along the
motorcycle’s frame and has weather-resistant connections at both ends. Excess cable is coiled
under the transceiver inside the weather-resistant enclosure.
Each end of the cable is strain-relieved with jackscrews at the control head and the transceiver.
The cable is shielded to reduce the effects of radio frequency interference and ignition sense noise.
5.1.4
Microphone
A weather-resistant, palm microphone and coiled cord plug into a pigtail connector on the control
cable. The microphone attaches to a hang-up bracket located within easy reach of the motorcycle
rider. The coiled cord is long enough to be operated by someone standing next to the motorcycle, yet
short enough to not interfere with the motorcycle’s steering or operation.
5.1.5
Keypad Mic
The Mobile Keypad Microphone (Mic) is a full keypad handheld microphone. The keypad on this
microphone is intended to assist in navigating through the menus on its parent device, as well as
entering information such as phone numbers and menu picks.
5.1.6
External Speaker
A 3.2-ohm, 10-watt-rated-audio-power, external speaker is mounted on the front of the motorcycle.
The speaker cable is routed along the motorcycle frame to the transceiver’s rear accessory
connector. A sealed, weather-resistant, speaker-muting (toggle) switch is mounted on top of the
speaker.
The external speaker connects to the rear accessory connector of the transceiver.
5.1.7
Headset Capability
The motorcycle radio is compatible with headset accessories that would provide hands-free
operation of the radio. Motorola does not manufacture headset equipment, but provides the
interconnection for headset equipment with the motorcycle radio. Aftermarket headset equipment is
available through Motorola (see Appendix A: Replacement Parts Ordering).
Caution
5.1.8
To avoid possible injury to hearing, the audio setting in the mobile radio MUST be
confirmed, if the Motorola mobile radio is used with any motorcycle helmet headset.
See CPS Help for details.
Antenna
The antenna(s) are mounted on top of the transceiver’s weather-resistant enclosure. 
The enclosure’s metal lining acts as the antenna’s ground plane.
5.1.9
Ignition Sense (ACC) Wire
The ignition sense wire connects to the motorcycle’s fuse box and is routed along the motorcycle
frame to the transceiver’s rear accessory connector.
The radio is wired so that transmission is inhibited if the motorcycle’s ignition sense switch is off. 
If the PTT switch is pressed with the ignition sense off, a low-frequency tone sounds. The receiver is
controlled by the control head on/off switch.

Installation Overview
5.2.1
General
5-3
All APX mobile radios are tested and inspected before shipment. It is, however, suggested that the
transmitter frequency, deviation, and power output be checked at the time of installation. It is the
license holder’s responsibility to ensure that the operating parameters of his station comply with
applicable laws governing radio communications equipment. For tests and alignment procedures,
refer to the appropriate service manual (refer to “Related Publications” on page vi).
Generally, the installation of the motorcycle radio takes place in the following parts:
• Mounting the universal mounting plate and related hardware at the rear of the motorcycle;
• Mounting the control head, speaker, microphone, and related hardware forward on the
motorcycle;
• Routing the power cable, control-head cable, speaker cable, and ignition sense cable to the
weather-resistant enclosure;
• Mounting the weather-resistant enclosure and radio chassis, and connecting the cables;
• Mounting the antenna(s) to the weather-resistant enclosure.
A universal mounting plate, supplied by Motorola, is first mounted to either a motorcycle carrier at the
rear of the motorcycle or to the rear frame of the motorcycle itself. The mounting procedures for the
universal mounting plate vary from motorcycle to motorcycle. Therefore, the procedures given in this
manual for installing the mounting plate may not specifically apply, but are provided for guidance.
The control head, speaker, and microphone are mounted forward on the motorcycle, on or near the
steering column. There are several possible mounting configurations which use a combination of
Motorola and customer-built brackets. These configurations are outlined in this manual. Because of
the large number of motorcycle makes and models in existence, the customer-built brackets are
necessary to tailor the mounting of the Motorola equipment to the particular motorcycle being used.
Suggestions for customer-built brackets are given in this manual.
The power cable, control-head cable, speaker cable, and ignition sense cable are routed to the
weather-resistant enclosure position. The enclosure and the radio chassis are then mounted. Special
care is required when connecting cables to the radio equipment within the enclosure.

5.2.2
Motorcycle Radio Installation Installation Overview
Important Installation Hints
Consider the following when mounting the radio components:
• Excess lengths of control-head, power, ignition sense, and speaker cables must be routed in
the enclosure as shown in Figure 5-16.
• All components must be mounted securely in order to withstand the constant and sometimes
severe vibration experienced on a motorcycle.
• No cantilever action, which could cause severe vibration, should be generated in the mounting
hardware.
• The control head and microphone must be placed for ease of accessibility by the motorcycle
operator.
• Forward components (control head, microphone, and speaker) should not interfere with visual
or physical access to controls and instruments.
• Forward components should not interfere with the handling of the motorcycle.
• Cabling between the control head and the radio chassis should be run to minimize interference
with operator movements.
• The weather-resistant enclosure should be placed to avoid any interference with the motorcycle
operator.
• Electrical continuity must be present through the enclosure shock mounts to the motorcycle
frame for proper electrical and RF grounding.
• The antenna(s) are designed for mounting on the top of the weather-resistant enclosure.
• Only the supplied microphone mounting clip should be used to ensure secure mounting of the
microphone. This clip has a very strong spring to ensure positive retention of the microphone
over rough terrain. Also, there must be electrical continuity from this clip to the motorcycle
frame for DC grounding.
• Direct access to the microphone should be provided from both sides of the motorcycle.
• Sufficient slack in the microphone coiled cord should be allowed so as not to impede steering.
• Mounting hardware must be stainless steel to prevent corrosion.
• If an extra length of cable is used to extend the microphone, ensure that the added capacitance
does not interfere with the operation of the radio.

Motorcycle Radio Installation Installing the Universal Mounting Plate
Installing the Universal Mounting Plate
The universal mounting plate, supplied with the motorcycle radio, must be mounted on the
motorcycle first. It provides the base on which the weather-resistant enclosure is to be mounted. 
The method used for mounting the plate depends on the make and model of the motorcycle and
whether the plate is mounted to a carrier or to the motorcycle chassis. After the plate has been
securely mounted to the motorcycle, mounting the weather-resistant enclosure onto the plate is
straightforward.
Figure 5-2 illustrates the universal mounting plate mounted to a motorcycle carrier. Since there are
so many makes and models of motorcycles and motorcycle carriers, it is impossible to give specific
step-by-step instructions for mounting the universal mounting plate. However, noting the following
considerations will aid in the installation procedure.
• A minimum of holes are predrilled into this plate as supplied. Mounting holes must be drilled as
required for the particular motorcycle on which the plate is being mounted.
• The universal mounting plate should be mounted on the motorcycle in such a manner that the
later mounting of the weather-resistant enclosure will not interfere with the motorcycle seat
back, with any other obstacles, or with the motorcycle operator. The enclosure may be
temporarily bolted to the universal mounting plate and the unit positioned on the motorcycle to
ensure the above criteria are met.
• To ensure a good grounding path from the universal mounting plate to the motorcycle carrier or
frame, stainless steel lock washers must be used with the mounting hardware in two areas to
score through the paint on the universal mounting plate and on the carrier or frame, thereby,
providing good electrical contact with the underside of the motorcycle carrier or motorcycle
frame.
Figure 5-2. Universal Mounting Plate Installation (Part of Radio Enclosure Kit)
Follow the procedures below to mount the universal mounting plate to the motorcycle 
(see Figure 5-2).
1. Determine the mounting position for the mounting plate.
2. Determine whether stainless steel spacers are required for clearance in mounting the plate.
3. Drill four 9/32-inch holes in the mounting plate and the corresponding motorcycle carrier or
chassis for mounting the plate.
4. Attach the universal mounting plate to the motorcycle using four machine screws, eight lock
washers, and four nuts. Tighten screws securely. The lock washers must cut through the
paint on the plate and motorcycle carrier or frame to ensure a good ground path.

Installing the Speaker and Control Head
NOTE: To disable the internal speaker of the O2 Control Head, please refer to Section 2.5.1: “Internal
Speaker Disassembly” on page 2-44.
The control head mounting location and configuration is determined largely by the make and model
of motorcycle. Two different mounting configurations are described below. One involves mounting
the speaker and control head together as a unit using the combination speaker/control-head bracket
(shown in Figure 5-4) supplied by Motorola. Alternately, the control head may be mounted by itself
using a smaller control-head bracket supplied by Motorola. In this case, the speaker is mounted
elsewhere. This section outlines installation procedures for each configuration mentioned above.
The customer (or installer) is in the best position to determine the most appropriate mounting
configuration for the control head and speaker based on the particular motorcycle on which the
equipment is to be mounted.
When determining its location, position the control head so that it is clearly visible and
within easy reach of the motorcycle operator.

Handlebar Installation with Speaker and Control Head Mounted Together
Figure 5-4 illustrates the combination speaker/control head bracket. This combination bracket is
used only when the control head and speaker are to be mounted as a unit. Also illustrated in
Figure 5-4 is a handlebar-mounting bracket which may be required if the combination speaker/
control-head bracket cannot be easily mounted to the motorcycle. In this case the 
handlebar-mounting bracket is mounted to the motorcycle, and the combination bracket is then
mounted to the handlebar-mounting bracket.

Provision has been made on the combination speaker/control-head bracket for mounting the
microphone hang-up clip. If that mounting is desired, the hang-up clip must be attached to the
bracket before installing the control head and speaker. See Section 5.6: “Installing the Microphone
Hang-Up Clip” on page 5-14 for the hang-up clip procedure. Install the speaker and control head as
described below.
1. Determine the location where the speaker/control head is to be mounted. Consider how the
speaker/control-head bracket may be mounted, and whether or not a handlebar-mounting
bracket is needed. Take care to select a location that is not only mechanically convenient, but
is located for ease of operation.
NOTE: The angle at which the handlebar-mounting bracket or the speaker/control-head bracket is
mounted to the motorcycle determines the firing angle of the speaker.
2. If the handlebar-mounting bracket is needed, install it first.
3. Mount the speaker/control-head bracket, either directly to the motorcycle, or, if used, to the
handlebar-mounting bracket, using four stainless-steel machine screws, lock washers, and
nuts.
4. Mount the 9-pin D-connector end of the motorcycle control-head cable to the speaker/control
head bracket, using two machine screws, flat washers, and nuts. (Cable routing directions
appear later in this section.)
5. Mount the speaker on the speaker/control-head bracket, using two machine screws and lock
washers. Torque these screws to 20 in-lbs.
6. Attach the control-head cable to the control head and tighten the locking screws on the
connector. This connection must be made before you mount the control head in the bracket.
(Cable routing directions appear later in this section.)
7. Mount the control head to the bracket, using two machine screws, lock washers, and flat
washers.
8. Adjust the control head viewing angle by loosening its mounting screws and rotating the
control head to the desired angle. Then, retighten screws to 20 in-lbs torque. This concludes
the speaker/control-head installation.
5.4.2
Fuel Tank Console Installation with Speaker and Control Head Mounted
Together
Some motorcycles provide a console for mounting radio equipment. This console is attached to the
top of the fuel tank. With the use of a mounting bracket, screws, nuts, and lock washers, the
combination speaker/control-head bracket can be mounted to this console. Figure 5-5 illustrates this
type of mounting.
The console attachment screws must be removed, and the console must be lifted slightly from the
fuel tank to gain access in order to attach mounting hardware, and to route cables later.
In this installation, the microphone (mic), mic hang-up bracket, and mic extension bracket will
interfere with handlebar travel.
Installation using this method is the same as in Section 5.4.1: “Handlebar Installation with Speaker
and Control Head Mounted Together” on page 5-8.

Handlebar Installation with Speaker and Control Head Mounted Separately
It may be necessary to use the smaller control head bracket (part number 07-80127N02) and mount
the speaker and microphone hang-up clip in another location on the motorcycle.
Before installing the control head using the bracket described above, the control-head end of the
control-head cable should be temporarily fastened to the control head, and the control head fastened
to its bracket. Motorola-supplied spacers and the mic-cable bracket are required to mount the control
head to the handlebar. This mic-cable bracket has holes to mount the microphone-cable connector.
Follow these procedures when mounting the smaller control-head bracket:
1. Determine the location at which the control head is to be mounted. Take care to choose a
location that is not only mechanically convenient, but is located for ease of operation.
2. Securely mount the Motorola-supplied spacers, mic-cable bracket, and small control-head
bracket to the handlebars.
3. Mount the 9-pin D-connector end of the motorcycle control-head cable to the mic-cable
bracket, using two machine screws, flat washers, and nuts. (Cable routing directions appear
later in this section.)
4. Attach the control-head end of the cable to the control head and tighten the locking screws on
the connector.
5. Mount the control head to the small control-head bracket, at the proper viewing angle, using
two wing screws. Tighten firmly. This concludes the control-head installation.

Other Hang-Up Clip Mounting
To mount the microphone hang-up clip in another location, a customer-supplied bracket may be
used. Suggested locations include the handlebars, fuel-tank console, or any location which provides
easy access to the microphone without blocking controls and indicators and without interfering with
motorcycle handling. See Figure 5-5, Figure 5-6, and Figure 5-7 for alternative microphone hang-up
clip mounting methods.
1. Fabricate a bracket, then secure it to the motorcycle.
2. Use two machine screws, lock washers, and nuts to secure the hang-up clip to the
customer-supplied bracket. Ensure that the microphone clip is DC grounded to the
motorcycle chassis (a grounding lug and strap are provided in the hang-up clip kit for this
purpose) – this is essential for proper radio operation.
5.7
Installing Antenna Base and Cables
NOTE: Antenna hole placement and cable routing in 7/800, VHF and UHF antenna manuals are not
applicable for the APX Series.
The GPS antenna assembly must be done after the removal of the metal liner but before
reinstalling the APX Series liner.
1. Open the top cover of the weather-resistant enclosure.
2. Uninstall the metal liner that is shipped attached to the weather-resistant enclosure. This liner
has one depressed area at the top of the enclosure liner just toward the rear of the enclosure.
This metal liner is not used with APX Series products.
3. Place the metal liner with two round, depressed areas toward the enclosure hinge and 5/8”
hole near the front of the housing, inside the top cover, and align the six slots in the metal
liner with the screw holes in the top housing.
4. The metal liner of the enclosure’s top cover acts as a ground plane for the antenna.
5. Locate the two round, depressed areas about 3 inches in diameter in the metal liner near the
enclosure hinge. Referring to Figure 5-8, these areas are either Band 1 or Band 2 depending
on the antenna port they align to. Refer to band markings on radio for the proper antenna port
location. For the GPS antenna, use the 5/8” hole near the front of the housing near the lock.

7. Remove the metal liner from the top cover.
8. For Band 1 and Band 2 positions, use the Motorola RPX-4378A Hole-Cutting Saw or
equivalent, and carefully drill a 3/4-inch hole at the marked location from the inside of the
cover until the saw bottoms out. For the GPS carefully drill a 9/16-inch hole at the marked
location from the inside of the cover until the saw bottoms out. The saw should clean a neat
circle to assure good contact between the antenna and the housing.
IMPORTANT:
For proper seating of the antennas, deburr and scrape any foreign
matter from both sides of the hole, being careful not to mar the
finish of the shell.
9. Clean the mounting surface around the hole to remove dirt and wax.
10. Refer to the Motorcycle GPS Instruction Manual for further installation instruction for the
GPS. GPS must be mounted before the APX metal liner is installed.
11. Reinstall the APX metal liner (see Figure 5-8) with the cable clamps provided in the weatherresistant housing. If installing GPS, the GPS coaxial cable must be fed through the hole in the
APX metal liner before the liner can be placed onto the housing. Then route the GPS Coaxial
Cable through the cable clamps before tightening the hex screws as installing the cable after
that is difficult due to the connector. See Figure 5-11 for GPS Cable Routing.

You may route the cables in any order. As you route each cable, temporarily fasten it at both ends.
When all cables have been run, permanently fasten the cables with appropriate cable tie wraps.
Observe the following during routing and hook-up:
1. Route the cables so that none interfere with motorcycle operation.
2. Fasten the cables with supplied nylon tie wraps. The wraps should be firmly installed at
frequent intervals along the cable length in such a manner that motorcycle vibration will not
cause metal fatigue and subsequent breakage of the cable wires.

is mounted to a carrier or the chassis itself, the transceiver MUST be properly grounded to
the motorcycle chassis. The ground strap supplied with the installation kit may have to be
used to ensure a good RF ground path from the radio transceiver to the motorcycle chassis.
4. Install the 3-foot ground strap on one of the front shock mounts. Route it through the cablerouting hole and connect the other end to the motorcycle frame (see Figure 5-15).
WARNING
6878215A01
DO NOT connect the ground strap directly to the negative battery post.

5. The diagram of the shock mount is shown loosely assembled. After the hex screws are
tightened, the rubber washers are compressed to fasten the weather- resistant enclosure
securely to the universal mounting plate.
6. Figure 5-17 is an exploded view of the enclosure; it shows details that will help to understand
how the enclosure is mounted. After the enclosure is completely mounted, check for proper
ground connection–continuity between the antenna ground plane and the motorcycle frame.
5.11 Transceiver and Cabling Installation
After the weather-resistant enclosure has been installed, the radio chassis (transceiver) is installed in
the enclosure and then appropriate cables are connected. However, before the transceiver can be
installed, the cabling must be properly positioned in the enclosure.
5.11.1 Installing Cabling in the Enclosure
Position the cabling in the weather-resistant enclosure as follows:
1. Run the speaker, power, control-head, and ignition sense cables into the enclosure.
2. Lay the excess cable length between the radio mounting bosses in an S configuration as
shown in Figure 5-16. Do not coil any excess cable. Use the supplied tie wraps to bundle
cable as shown.
NOTE: If the extra cable length is not sufficient to match the illustrated cable routing, then match the
illustration as closely as possible.
3. Connect the speaker cable to the accessory cable connector.
NOTE: The accessory-cable emergency connector is shipped with a shorting plug installed. The
headset connector is also shipped with a shorting plug installed. The plugs must remain in if
an emergency switch and/or headset is not used. If an emergency switch and/or headset is
used, remove the shorting plug(s) and discard.
4. Install the mounting plate in position on top of the cables installed above. Take care not to
damage or pinch the cables when securing the mounting plate in position.
NOTE: At this point, the control-head cable plug should be located at the forward end of the
enclosure, and the power-cable, speaker-cable, and accessory-cable plugs should be located
at the rear of the enclosure.

Miscellaneous Information
On the mid power and 100W radios, there are rubber port plug which seals an opening which is used
for a future antenna connection. On the mid power, the port plug is located at the bottom of the radio
behind the control head or TIB. On the high power, the port plug is located at the TIB. These plugs
are critical to the sealing of the radio and should not be removed unless to replace it due to damage
or to install the future antenna connector. Removal of the port plug in any other situation would
create a leak path into the radio.

Chapter 7 Best Practices: Installation & Troubleshooting
In this section are Motorola recommended vehicle installation practices that can address or prevent
many issues, including:
• Radio circuit damage due to over voltage condition
• Radio/Accessories "lock up"
• Radio/Accessories change state/lock-up when radio PTT is depressed
• Radio powers up in the FL 01/90 state (general communication error code)
• Radio intermittently resets
• Radio loses secure key
• Transmit audio distortion on motorcycle radio when engine is running
• Keypad buttons become inoperative for motorcycle radios when engine is running
• Alternator whine present when transmitting with engine running
• Radio/Accessories turn themselves on/off
7.1
Check Wiring of Ignition and Radio Ignition Sensing
• If it is required to turn the radio on and off via the ignition sense switch, in addition to the control
head’s on/off switch, connect the ignition sense lead to the accessory terminal from the ignition
switch (usually in the vehicle’s fuse panel under accessory or radio).
NOTE: Motorola recommends protecting or isolating the radio’s ignition sense input from voltage spikes
in excess of +/- 40VDC. Such spikes can be hundreds of volts in amplitude and are common in
larger vehicles (utility trucks, buses and etc.), especially when the source is common to a
solenoid coil. A triggerable oscilloscope is required to determine the existence of such spikes as
most voltmeters cannot measure in short duration (< 1 msec). If the condition of the intended
ignition sense source is unknown, Motorola recommends isolating the source from the radio with
a relay or the use of a suppression diode wired between the source and ground. Any high current
suppression diode (i.e. MR2535) with a breakdown voltage of between 18 and 40 volts will
suffice. A suitable diode kit is available from Motorola parts, kit number HLN6325_.
• If it is required to have the radio power up only via the control head’s on/off switch, then connect
the ignition sense lead directly to the positive terminal of the battery. This will mean the ignition
sense will always be ignored and a re-wiring will be necessary in the future if the operator
chooses any ignition sense CPS setting.
7-2
7.2
Best Practices: Installation & Troubleshooting
Check Physical Installation of Radio Ground and Radio Accessory Wiring
Check Physical Installation of Radio Ground and Radio Accessory
Wiring
• Take care to scrape away paint on the chassis at the place where the ground connection is
to be made, and try to keep the ground lead as short as possible.
• Verify that the A+ lead (red) is connected directly to the positive terminal of the battery and
the ground lead (black) is connected to the vehicle’s chassis using as short of a length of
wire as is practical.
• For vehicles that have other types of electronic equipment installed (lights, flashers,
computers siren/PA and etc.), use a separate ground for the mobile radio equipment.
• Make sure that the mobile radio antenna is the minimum required distance (three feet) from
the mobile radio equipment to prevent radio frequency interference (RFI) from interfering
with the radio and/or accessories.
• Do not coil up any excess length of the A+ (red) lead. Doing this may cause a large transient
voltage to be produced when there is a high current drain (e.g. during transmit). This could
cause the radio to reset when the push-to-talk (PTT) is depressed.
• For motorcycle mounted radios, make sure that the antenna ground connection is solid. An
intermittent ground connection can cause the transmission to be distorted when the
motorcycle’s engine is running.
• Do not coil up any excessive length of antenna cable, if possible. It may affect the radio’s
receive performance.
• If an extra length of cable is used to extend the microphone, make sure the added
capacitance does not interfere with the operation of the radio.
7.3
Improve the Electrical Quality of the Power and Ignition Lines
• Use a relay to isolate the vehicle’s ignition switch point (ACC) from the radio’s ignition sense
point. Control this relay from the vehicle’s ignition switch point (ACC). Supply a cleaner
voltage from the positive terminal of the battery into the relay, which will now be attached to
the radio’s ignition sense point. Now the ACC line toggles the relay, instead of directly
toggling the radios ignition sense line.
• Install a Power Line Filter between the A+ lead and the positive terminal of the battery. This is
intended to filter the battery power applied to the transmitter power amplifiers. Pay extra
caution to this because the series filter will introduce a negative spike when the radio
transmits that may cause problems with radio operation. Lock-up issues have been seen
with the dual control head MCS 2000 configuration.
• For vehicles that use electromechanical relays to control external devices (lights, motors,
switch boxes and etc.), these relay circuits should be isolated as best as possible from the
mobile radio equipment. Also, diode suppression should be used across the relay contacts to
minimize the noise produced by the collapsing magnetic field.
• If the ignition sense switch is to be used, make sure that there is not a large voltage drop
between the A+ point (usually the positive terminal of the battery) and the ignition sense
point. In general, the voltage difference between these two points, should not be greater than
1.5 volts when all accessories/air-conditioner, etc. are turned on. Refer to the Basic Service
Manual for specifications for minimum and maximum voltage levels. Typical battery voltage
levels are 13.6V +/- 20%.
6878215A01
Best Practices: Installation & Troubleshooting Minimize the Effect of Poorly Grounded Antennas
7.4
7-3
Minimize the Effect of Poorly Grounded Antennas
• For vehicles with high power (100W) radios that use glass mount antennas, care must be
taken to keep the radio and antenna cable as far as possible from the radiating element of
the antenna. If a sufficient distance is not maintained, the glass mount antenna’s lack of a
proper ground plane may cause the radio’s transmit signal to interfere with itself and cause a
reset. To minimize this effect, it may be necessary to install ferrite beads on the antenna
cable to protect the radio from this interference.
7.5
Jump-Start the Vehicle
Do not jump-start vehicle with radio power or ignition sense cables connected.
Damage to the radio and/or accessories may result.
Caution
Jump-starting a motorcycle can crank 300+ volts through the vehicle’s charging system and these
transients can damage electrical equipment.
The state of your radio prior to needing a jump-start may be unknown, and the radio may attempt to
return to its last state (radio ON), when doing a jump-start. Therefore, Motorola recommends the
following steps be taken before jump-starting any vehicle containing a radio.
1. Locate the ignition sense line (thin yellow wire or thin red wire, depending on dash mount or
remote mount installation) and the main power leads (thick red wire) near the battery positive
terminal.
NOTE: These lines are fused. In the event these lines are not fused (add the appropriate fuse in line)
use whatever tools necessary to physically disconnect the ignition sense and power lines
from the battery terminal.
Make sure that the disconnected lines are not in the way of moving motorcycle parts or
interfering with the motorcycle operation in any way.
2. Open up the fuse holders and remove the fuses out of the kits.
3. Re-tighten the fuse holders but without the fuses to insure that ignition sense and power lines
do not interfere with moving motorcycle parts.
4. Proceed with the jump-start routine as described by your vehicle owner’s manual.
5. Once the jump-start process is complete, re-install the fuses into their holders.
7.6
Eliminate Noise/Howling from PA Speaker
1. Refer to Section 2.1.1 for recommended methods of installation available for the mobile 
two-way radio, with accessories placed to the vehicle as desired.
2. Refer to Figure 2-16 and Figure for the wiring diagrams for the recommended configurations.
3. Refer to the Siren/PA User Manual (part number 6881093C18) for further details on lowering
the wattage.

Glossary
Glossary
This glossary contains an alphabetical listing of terms and their definitions that are applicable to the
ASTRO radio.
Term
Definition
analog
Refers to a continuously variable signal or a circuit or device designed
to handle such signals. See also digital.
band
Frequencies allowed for a specific purpose.
CPS
See Customer Programming Software.
Customer
Programming
Software
Software with a graphical user interface containing the feature set of an
ASTRO radio.
default
A pre-defined set of parameters.
D.E.K
Direct Entry Keyboard.
digital
Refers to data that is stored or transmitted as a sequence of discrete
symbols from a finite set; most commonly this means binary data
represented using electronic or electromagnetic signals. See also
analog.
EEPROM
See Electrically Erasable Programmable Read-Only Memory.
Electrically Erasable
Programmable
Read-Only Memory
A special type of PROM that can be erased by exposing it to an
electrical charge. An EEPROM retains its contents even when the
power is turned off.
FCC
Federal Communications Commission.
firmware
Code executed by an embedded processor such as the Host or DSP in
a subscriber radio. This type of code is typically resident in non-volatile
memory and as such is more difficult to change than code executed
from RAM.
frequency
Number of times a complete electromagnetic-wave cycle occurs in a
fixed unit of time (usually one second).
kHz
See kilohertz.
kilohertz
One thousand cycles per second. Used especially as a radio-frequency
unit.
MCU
See microcontroller unit.
MHz
See Megahertz.
Glossary-2
Term
Definition
Megahertz
One million cycles per second. Used especially as a radio-frequency
unit.
microcontroller unit
Also written as μC. A microprocessor that contains RAM and ROM
components, as well as communications and programming components
and peripherals.
PA
Power amplifier.
paging
One-way communication that alerts the receiver to retrieve a message.
PTT
See Push-to-Talk.
Publication Manual
Revision
A publication that provides supplemental information for its parent
publication before it is revised and reissued.
Push-to-Talk
The switch or button that causes the radio to transmit when pressed.
When the PTT switch or button is released, the unit returns to standby
or receive operation.
radio frequency
The portion of the electromagnetic spectrum between audio sound and
infrared light (approximately 10 kHz to 10 GHz).
RAM
See random access memory.
random access
memory
A type of computer memory that can be accessed randomly; that is, any
byte of memory can be accessed without touching the preceding bytes.
receiver
Electronic device that amplifies RF signals. A receiver separates the
audio signal from the RF carrier, amplifies it, and converts it back to the
original sound waves.
registers
Short-term data-storage circuits within the microcontroller unit or
programmable logic IC.
RESET
Reset line: an input to the microcontroller that restarts execution.
RF
See radio frequency.
RX
Receive.
signal
An electrically transmitted electromagnetic wave.
software
Computer programs, procedures, rules, documentation, and data
pertaining to the operation of a system.
time-out timer
A timer that limits the length of a transmission.
TOT
See time-out timer.
transceiver
Transmitter-receiver. A device that both transmits and receives analog
or digital signals. Also abbreviated as XCVR.
transmitter
Electronic equipment that generates and amplifies an RF carrier signal,
modulates the signal, and then radiates it into space.
