Introduction 
This chapter of the manual describes preventive maintenance, safe handling 
of CMOS devices, and repair procedures and techniques. Each of these topics 
provides information vital to the successful operation and maintenance of 
your radio. 
Preventive 
Maintenance 
The radios do not require a scheduled preventive maintenance program; 
however, periodic visual inspection and cleaning is recommended. 
Inspection 
Check that the external surfaces...

 
2-2Basic Maintenance  
Upon completion of the cleaning process, use a soft, absorbent, lint-free cloth 
to dry the area. Do not brush or apply any isopropyl alcohol to the frame, 
front cover, or back cover.
Always use a fresh supply of alcohol and a clean container to prevent 
contamination by dissolved material (from previous usage). 
Safe Handling 
of CMOS 
Devices 
Complementary metal-oxide semiconductor (CMOS) devices are used in 
this family of radios. While the attributes of CMOS are many, their...

18.Always wear a conductive wrist strap when servicing this equipment. 
The Motorola part number for a replacement wrist strap that connects to 
the table mat is 42-80385A59.
19.When straightening CMOS pins, provide ground straps for apparatus used.
20.When soldering, use a grounded soldering iron.

Substitution 
Special care should be taken to be as certain as possible that a suspected 
component is actually the one at fault. This special care will...

 
2-4Basic Maintenance 
Audio PA Component Replacement Procedure 
For High Power Models 
This procedure must be used when replacing these components to ensure 
proper alignment and heatsinking.  
1.Remove the main board from the chassis per disassembly instructions in 
Chapter 5.
2.Remove the faulty component in the Audio PA section of the main 
board. Ensure that the through-holes are free of solder.
3.Place the main board in a chassis eliminator (Motorola Part Number 
2705815W03). Assemble the screws...

 
Basic Maintenance2-5 
Antenna/Power Connector Replacement Procedure 
For Low, Mid, and High Power Models 
Note that Figures show High Power Chassis, but apply to all power levels.
1.Remove damaged connector by heating the solder 
joints until they reßow. Pull connector from board 
with small pliers or like instrument.
2.Place new connector (either Power or RF) in 
opening in chassis (See Figure 2-1.). Connector 
Part Numbers can be found in Chapter 10.
3.Install connector retaining clip over connector...
