SAFETY INFORMATION
Read this information before using your radio.

PRODUCT SAFETY AND RF EXPOSURE FOR MOBILE TWO-WAY RADIOS
INSTALLED IN VEHICLES OR AS FIXED SITE CONTROL STATIONS.
This document provides information and instructions for the safe and efficient operation of Motorola
Mobile Two-Way Radios. The information provided in this document supersedes information
contained in user guides published prior to February 2002.

RF Energy Exposure Awareness and Control Information, and Operational
Instructions for FCC Occupational Use Requirements
Note: This radio is intended for use in occupational /controlled conditions, where users have full
knowledge of their exposure and can exercise control over their exposure to meet FCC/ICNIRP limits.
This radio device is NOT authorized for general population, consumer or any other use.
This 2-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. It uses radio frequency (RF) energy or
radio waves to send and receive calls. RF energy is one form of electromagnetic energy. Other forms
include, but are not limited to, sunlight and x-rays. RF energy, however, should not be confused with
these other forms of electromagnetic energy, which when used improperly, can cause biological
damage. Very high levels of x-rays, for example, can damage tissues and genetic material.
Experts in science, engineering, medicine, health and industry work with organisations to develop
standards for safe exposure to RF energy. These standards provide recommended levels of RF
exposure for both workers and the general public. These recommended RF exposure levels include
substantial margins of protection.
All Motorola 2-way radios are designed, manufactured and tested to ensure they meet governmentestablished RF exposure levels. In addition, manufacturers also recommend specific operating
instructions to users of 2-way radios. These instructions are important because they inform users
about RF energy exposure and provide simple procedures on how to control it.
Please refer to the following Web sites for more information on what RF energy exposure is and how
to control your exposure to assure compliance with established RF exposure limits.
http://www.fcc.gov/oet/rfsafety/rf-faq.html
http://www.osha.gov/SLTC/radiofrequencyradiation/index.html

Federal Communications Commission Regulations (US markets only)
The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for mobile 2way radios before they can be marketed in the U.S. When 2-way radios are used as a consequence
of employment, the FCC requires users to be fully aware of and able to control their exposure to meet
occupational requirements. Exposure awareness can be facilitated by the use of a label directing
users to specific user awareness information. Your Motorola 2-way radio has an RF exposure product
label. Do not remove this RF exposure label from the device. Also, your Motorola user manual, or
separate safety booklet, includes information and operating instructions required to control your RF
exposure and to satisfy compliance requirements.

Compliance with RF Exposure Standard
Your Motorola radio is designed and tested to comply with a number of national and international
standards and guidelines (listed below) regarding human exposure to radio frequency
electromagnetic energy. This radio complies with IEEE and ICNIRP exposure limits for
occupational/controlled RF exposure environments at duty factors of up to 50% talk–50% listen and
is authorised by the IEEE/ICNIRP for occupational use. In terms of measuring RF energy for
compliance with these exposure guidelines, your radio antenna radiates measurable RF energy only
while it is transmitting (during talking), not when it is receiving (listening) or in standby mode.

Your Motorola two-way radio complies with the following RF energy exposure standards and
guidelines:

RF Exposure Compliance and Control Guidelines and Operating Instructions
To control exposure to yourself and others and to ensure compliance with the RF exposure limits,
always adhere to the following procedures.

Guidelines:
●
●

User awareness instructions should accompany device when transferred to other users.
Do not use this device if the operational requirements described herein are not met.

Instructions:
●

●

Transmit no more that the rated duty factor of 50% of the time. To transmit (talk), push the
Push-To-Talk (PTT) button. To receive calls, release the PTT button.
Transmitting 50% of the time, or less, is important because this radio generates measurable RF
energy exposure only when transmitting (in terms of measuring for standards compliance).
Transmit only when people outside the vehicle are at least the recommended minimum
lateral distance away, as shown in Table 1, from the body of a vehicle with a properly
installed antenna. This separation distance will ensure that there is sufficient distance from a
properly installed (according to installation instructions) externally-mounted antenna to satisfy the
RF exposure requirements in the standards listed above.

Note:Table 1 lists the recommended lateral distance for bystanders in an uncontrolled environment
from the body of a vehicle with an approved, properly installed transmitting antenna (i.e monopoles
over a ground plane, or dipoles) at several different ranges of rated radio power for mobile radios
installed in a vehicle.
Table 1: Recommended Lateral Distances
Mobile Radio Rated Power
(see Note below)

Minimum Lateral Distance From
Vehicle Body

Less than 7 Watts

20 cm (8 Inches)

7 to 15 Watts

30 cm (1 Ft)

16 to 39 Watts

60 cm (2 Ft)

40 to 110 Watts

90 cm (3 Ft)

If you are not sure of the rated power of your radio, contact your Motorola representative or dealer
and supply the radio model number found on the radio model label. If you cannot determine the rated
power out, then assure 90cms (3 feet) separation from the body of the vehicle.

Mobile Antenna Installation Guidelines
●

●

These mobile antenna installation guidelines are limited to metal body motor vehicles or vehicles
with appropriate ground planes.
Antennas should be installed in the centre area of the roof or the trunk lid taking into account the
bystander exposure conditions of backseat passengers and according to the specific instructions
and restrictions in the Radio Installation Manual along with the requirements of the antenna
supplier.
Trunk lid installations are limited to vehicles with clearly defined flat trunk lids, and in some cases, to
specific radio models and antennas. See the Radio Installation Manual for specific information on
how and where to install specific types of approved antennas to facilitate recommended operating
distances to all potentially exposed persons.
Use only Motorola-approved supplied antenna or a Motorola approved replacement antenna.
Unauthorised antennas, modifications, or attachments could damage the radio and may result in
non-compliance with RF Safety Standards.

Approved Accessories

Compliance and Control Guidelines and Operating Instructions for Mobile Two-Way
Radios Installed as Fixed Site 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 on page page iv:
●
●

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 insure that
exposure limits are not exceeded.

Electromagnetic Interference/Compatibility
Note: Nearly every electronic device is susceptible to electromagnetic interference (EMI) if
inadequately shielded, designed or otherwise configured for electromagnetic compatibility. It may be
necessary to conduct compatibility testing to determine if any electronic equipment used in or around
vehicles or near fixed site antenna is sensitive to external RF energy or if any procedures need to be
followed to eliminate or mitigate the potential for interaction between the radio transmitter and the
equipment or device.

Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any
facility where posted notices instruct you to do so. Hospitals or health care facilities may be
using equipment that is sensitive to external RF energy.

Vehicles
To avoid possible interaction between the radio transmitter and any vehicle electronic control
modules, such as, ABS, engine, or transmission controls, the radio should be installed only by an
experienced installer and that the following precautions be used when installing the radio:
1. Refer to the manufacturer’s instructions or other technical bulletins for recommendations on radio installation.

2. Before installing the radio, determine the location of the electronic control modules and their harnesses in
the vehicle.

3. Route all radio wiring, including the antenna transmission line, as far away as possible from the electronic
control units and associated wiring.

Driver Safety
Check the laws and regulations on the use of radios in the area where you drive. Always obey them.
When using your radio while driving, please:
●
●

Give full attention to driving and to the road.
Pull off the road and park before making or answering a call if driving conditions so require.

MAINTENANCE
1.0

Introduction
This chapter provides details about the following:

2.0

❑

Preventive maintenance (inspection and cleaning).

❑

Safe handling of CMOS and LDMOS devices.

❑

Disassembly and reassembly of the radio.

❑

Repair procedures and techniques.

❑

Installation of Option Boards.

Preventive Maintenance
The radios do not require a scheduled preventive maintenance program; however, periodic visual
inspection and cleaning is recommended.

2.1

Inspection
Check that the external surfaces of the radio are clean, and that all external controls and switches
are functional. It is not recommended to inspect the interior electronic circuitry.

2.2

Cleaning Procedures
The following procedures describe the recommended cleaning agents and the methods to be used
when cleaning the external and internal surfaces of the radio. External surfaces include the front
cover and housing assembly. These surfaces should be cleaned whenever a periodic visual
inspection reveals the presence of smudges, grease, and/or grime.
NOTE Internal surfaces should be cleaned only when the radio is disassembled for service or

repair.
The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild
dishwashing detergent in water. The only factory recommended liquid for cleaning the printed circuit
boards and their components is isopropyl alcohol (70% by volume).

CAUTION: The effects of certain chemicals and their vapors can have harmful results on
certain plastics. Avoid using aerosol sprays, tuner cleaners, and other chemicals.

Cleaning External Plastic Surfaces
Apply the 0.5% detergent-water solution sparingly with a stiff, non-metallic, short-bristled brush to
work all loose dirt away from the radio. Use a soft, absorbent, lintless cloth or tissue to remove the
solution and dry the radio. Make sure that no water remains entrapped near the connectors, cracks,
or crevices.

2-2

MAINTENANCE

Cleaning Internal Circuit Boards and Components
Isopropyl alcohol (100%) may be applied with a stiff, non-metallic, short-bristled brush to dislodge
embedded or caked materials located in hard-to-reach areas. The brush stroke should direct the
dislodged material out and away from the inside of the radio. Make sure that controls are not soaked
with alcohol. Do not use high-pressure air to hasten the drying process since this could cause the
liquid to collect in unwanted places. After completing of the cleaning process, use a soft, absorbent,
lintless cloth to dry the area. Do not brush or apply any isopropyl alcohol to the frame, front cover, or
top cover.
NOTE Always use a fresh supply of alcohol and a clean container to prevent contamination by

dissolved material (from previous usage).

3.0

Safe Handling of CMOS and LDMOS Devices
Complementary metal-oxide semiconductor (CMOS) devices are used in this family of radios, and
are susceptible to damage by electrostatic or high voltage charges. Damage can be latent, resulting
in failures occurring weeks or months later. Therefore, special precautions must be taken to prevent
device damage during disassembly, troubleshooting, and repair.
Handling precautions are mandatory for CMOS circuits and are especially important in low humidity
conditions. DO NOT attempt to disassemble the radio without first referring to the following
CAUTION statement.

CAUTION: This radio contains static-sensitive devices. Do not open the radio unless you are
properly grounded. Take the following precautions when working on this unit:
❑

Store and transport all CMOS devices in conductive material so that all exposed
leads are shorted together. Do not insert CMOS devices into conventional plastic
“snow” trays used for storage and transportation of other semiconductor devices.

❑

Ground the working surface of the service bench to protect the CMOS device. We
recommend using the Motorola Static Protection Assembly (part number
0180386A82), which includes a wrist strap, two ground cords, a table mat, and a
floor mat.

❑

Wear a conductive wrist strap in series with a 100k resistor to ground.
(Replacement wrist straps that connect to the bench top covering are Motorola part
number 4280385A59)

❑

Do not wear nylon clothing while handling CMOS devices.

❑

Do not insert or remove CMOS devices with power applied. Check all power
supplies used for testing CMOS devices to be certain that there are no voltage
transients present.

❑

When straightening CMOS pins, provide ground straps for the apparatus used.

❑

When soldering, use a grounded soldering iron.

❑

If at all possible, handle CMOS devices by the package and not by the leads. Prior
to touching the unit, touch an electrical ground to remove any static charge that you
may have accumulated. The package and substrate may be electrically common. If
so, the reaction of a discharge to the case would cause the same damage as
touching the leads.

Repair Procedures and Techniques — General

4.0

2-3

Repair Procedures and Techniques — General
Parts Replacement and Substitution
When damaged parts are replaced, identical parts should be used. If the identical replacement part
is not locally available, check the parts list for the proper Motorola part number and order the part
from the nearest Motorola Parts centre listed in the “Piece Parts” section in Chapter 1 of this manual.
Rigid Circuit Boards
This family of radios uses bonded, multi-layer, printed circuit boards. Since the inner layers are not
accessible, some special considerations are required when soldering and unsoldering components.
The printed-through holes may interconnect multiple layers of the printed circuit. Therefore, exercise
care to avoid pulling the plated circuit out of the hole.
When soldering near the RF connector, potentiometer, 16-pin and 20-pin connectors:

5.0

❑

Avoid accidentally getting solder in the connector.

❑

Be careful not to form solder bridges between the connector pins.

❑

Examine your work closely for shorts due to solder bridges.

Disassembling and Reassembling the Radio — General
Since these radios may be disassembled and reassembled with the use of only 14 (board to casting)
screws, it is important to pay particular attention to the snaps and tabs, and how parts align with

TRANSCEIVER PERFORMANCE TESTING

RF Test Mode (5-Tone Radios)
When the radio is operating in its normal environment, it is not possible to test all individual aspects
of the transmitter and receiver performance. Therefore a special “test mode” is used to allow the
service technician to perform certain functional tests on the product. A control head fuctional test
mode is also available.
To enter test mode (CM360):
1.

Turn the radio on.

Within less than one second of the power-up beep, press button P2, five times in succession.

Six characters appear on the 8-character display, ‘TT XX CC’, where ‘TT’ indicates the test
environment (Table 3.2), ‘XX’ indicates the channel number 1-14 (Table 3.4), and ‘CC’
indicates the channel spacing (Table 3.3). Test frequencies (channels) may be changed with
use of the Up-Down button. Each additional press of P2 will scroll through the remaining
channel spacings supported.

Pressing P1 scrolls through and accesses test environments as shown in Table 3-2.

Pressing P2 for at least one second switches the radio to the control head test mode. ‘LCD
Test’ appears on the display.

Pressing P1 causes the radio to turn on all segments of the first character. A second P1 press
turns on all the segments of the second character and so on until all segments of all eight
characters are illuminated.

Pressing P1 at the end of the LCD test activates the ‘Icon & LED Test’. The next P1 press
turns on the first icon. Successive presses of P1 cycle through all icons and finally the three
LEDs.

Pressing P1 at the end of the ‘Icon & LED Test’ activates the button test. When a button is
pressed a single beep is heard and another beep on each release of all four P buttons plus
the Up-Down button.

Pressing P2 for at least one second in the control head test mode causes the radio to return
to the RF test mode.

Note: The radio powers up on the last used test state i.e. the last used test environment and
channel spacing, but always starts at channel 1.
To enter test mode (CM340):
1.

Turn the radio on.

Within less than one second of the power-up beep, press button P2, five times in succession.

The three LEDs will turn on and the single character segment display will indicate channel 1.
As the display can only show 1 to 8, channels 1 to 7 are repeated with a dot on the display to
indicate high power. Channels 1 to 7 with no dot represent low power (Table 3.4). An audio
alert will sound to indicate the test environment.

Pressing P1 will scroll through the other 12 test environments with its associated audio beep.
(Table 3.2)

Press P2 to scroll through the three supported channel spacings channel spacings supported
(Table 3.3)

Pressing P2 for at least one second switches radio to the control head test mode. A beep will
sound and the segment goes blank.

Pressing P1 will cycle scroll through the segment test, then the LED test and finally the HI/LO
power segment indicator; a high pitched beep will also sound as P1 is pressed.

RF Test Mode (5-Tone Radios)

3-3

In this mode all buttons, when pressed and held, will emit a high pitched beep and another
when the button is released to verify button functionality.

Pressing P2 for at least one second will return the user to RF Test Mode

RF Test Mode (MDC Radios)
When the radio is operating in its normal environment, it is not possible to test all individual aspects
of the transmitter and receiver performance. Therefore a special “test mode” is used to allow the
service technician to perform certain functional tests on the product. A control head fuctional test
mode is also available.
To enter test mode (display radios):
1.

Turn the radio on.

Within ten seconds after the self test is complete, press button P2, five times in succession.

Channel number appears in the display. The radio is on channel XX*, carrier squelch mode,
25 kHz channel spacing.

Each additional press of P2 scrolls through to the next channel spacing and a corresponding
set of tones are sounded.

Pressing P1 scrolls through and accesses test environments as shown in Table 3-5.

Pressing P2 for three seconds switches the radio to the control head test mode and zero
appears on the display.

Pressing P1 causes the radio to display the channel number “1”. Another P1 press causes the
radio to display the next channel “2”, and so on until channel “9”.

Pressing P1 at the end of the LCD test activates the ‘LED Test’. The next P1 press turns the
LEDs and dot On/Off.

Pressing P1 at the end of the LED test activates the button test. Pressing any button (except
P1) or any keypad button during the LCD test or Icon test immediately activates this test.

10. Pressing P2 for 3 seconds in the control head test mode causes the radio to return to the RF
test mode.

POWER UP SELF-TEST
1.0

Error Codes (5-Tone Radios)
Turning on the radio starts a self-test routine that checks the radio functionality. If the checks are
successful, the radio generates a high-pitched self-test pass tone. If the self-test is not successful,
one low-pitched (300Hz) error tone is heard and the RED LED flashes several times to indicate the
reason for the failure (see Table 5-1 below). After flashing the error code, the LED remains off for 5
seconds and then repeats the error code. The LED sequence and the error tone continue until the
radio is switched off. Radios with displays are also able to display error codes. The meaning of the
LED indication, the displayed error codes and the related corrections are listed in Table 5-1.

POWER UP SELF-TEST

Error Codes (MDC Radios)
Turning on the radio starts a self-test routine that checks the RAM, ROM checksum, EEPROM
hardware, and EEPROM checksum. If these checks are successful, the radio generates two highpitched self-test pass tones. If the self-test is not successful, one low-pitched tone is heard. Radios
with displays are able to display the error codes. Following are the possible errors and the related
corrections.

Retest the radio by turning it off and turning it on
again. If bad tone reoccurs, replace RAM (U0122).

Microphone Connector Pin Function

Function

Description

9.3V

Boot/DTMF
Keypad Column

This pin function depends on the voltage applied to pin 3 (See pin 3, Hook
description).
When configured as “Boot”, applying 5V to this pin will set the radio to Boot
state.
When configured as “DTMF Keypad Column”, this pin will carry column
voltages generated by the DTMF microphone (RMN5029).

Hook

When 0V is applied to this pin (mic on hook), pins 2 and 7 will be
configured to “Column” and “Row”.
When no voltage is applied to this pin (mic off hook), this pin will read 2.7V,
and pins 2 and 7 will be configured to “Column” and “Row”.
When 9.3V is applied to this pin (programming cables or Mag One mic
RMN5018), pins 2 and 7 will be configured to “Boot” and “SCI”.

Ground

Mic. Audio

Audio input impedance: 500 ohms
80 mV rms input (standard mic) or 1.8 mV rms (low cost mic) at 1 kHz for
60% deviation.
This path is enabled when Mic. PTT (pin 6) is keyed

Mic. PTT

Microphone PTT is active low, so this port reads “0” when PTT is pressed
and “1” when PTT is released.
10 K ohms internal pull up resistor to 9.3 V.
Pulling low this pin will also pull low, via a diode, pin 3 (external MIC PTT)
of the accessory connector.

SCI/DTMF
Keypad Row

The function of this pin depends on the voltage applied to pin 3 (see pin 3
description).
When configured as “SCI”, serial communication with the radio is
facilitated.
When configured as “DTMF Keypad Row” this pin will carry new voltages
generated by the DTMF mic (RMN5029)

Handset Rx
Audio

Handset audio output provides de-emphasized, muted Rx audio. The
source impedance is 10 ohms and the output level (open circuit) is
controlled by the volume control setting.

Regulated 9.3V Supply (50mA max.)

Used as ground
