1.0Introduction
!
This chapter provides details about the following:
•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.
2.0Preventive Maintenance
The radios do not require a scheduled preventive maintenance program; however, periodic visual
inspection and cleaning is recommended.
2.1Inspection
Chapter 2
MAINTENANCE
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.
2.2Cleaning 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
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.
Internal surfaces should be cleaned only when the radio is disassembled for service or
repair.
Page 16
2-2MAINTENANCE
!
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).
3.0Safe 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.
Page 17
Repair Procedures and Techniques — General2-3
4.0Repair 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 center 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:
•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.
5.0Disassembling 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
each other.
The following tools are required for disassembling/assembling the radio:
•Small flat blade screwdriver
•Phillips small 1# screwdriver
•TORX™ T9 screwdriver
•TORX™ T10 screwdriver
•Torque screwdriver set
•Torque spanner
•Hex tool (part no. 6680334F39)
If a unit requires more complete testing or service than is customarily performed at the basic level,
send this unit to a Motorola Authorized Service Center. (See Chapter 1 for a list of authorized
service centers.)
The following disassembly procedures should be performed only if necessary:

1.0General
These radios meet published specifications through their manufacturing process by utilizing highaccuracy laboratory-quality test equipment. The recommended field service equipment approaches
the accuracy of the manufacturing equipment with few exceptions. This accuracy must be
maintained in compliance with the manufacturer’s recommended calibration schedule.
2.0Setup
Supply voltage is provided using a power supply (13.8 Vdc for low power models, 13.6 Vdc for high
power models). The equipment required for alignment procedures is connected as shown in the
Radio Tuning Test Setup Diagram, Chapter 4, Figure 4-6.
Initial equipment control settings should be as indicated in Table 3-1. The remaining tables in this
chapter contain the following related technical data:

3-2TRANSCEIVER PERFORMANCE TESTING
3.0RF Test Mode
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.
2.Within ten seconds after the self test is complete, press button P2, five times in succession.
3.Channel number appears in the display. The radio is on channel XX*, carrier squelch mode,
25 kHz channel spacing.
4.Each additional press of P2 scrolls through to the next channel spacing and a corresponding
set of tones are sounded.
5.Pressing P1 scrolls through and accesses test environments as shown in Table 3-2.
6.Pressing P2 for three seconds switches the radio to the control head test mode and zero
appears on the display.
7.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”.
8.Pressing P1 at the end of the LCD test activates the ‘LED Test’. The next P1 press turns the
LEDs and dot On/Off.
9.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.

1.0Error Codes
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 high-
pitched 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
connections.
Possible ErrorsTo correct the problem...
RAM test failure.Retest the radio by turning it off and turning it on
