Safe Handling of CMOS and LDMOS
Complementary metal-oxide semiconductor (CMOS) devices are used in this family of radios.
CMOS characteristics make them 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 CMOS
CAUTION paragraph in the Disassembly and Reassembly section of the manual.

General Repair Procedures and Techniques
Any rework or repair on Environmentally Preferred Products must be done using the appropriate
lead-free solder wire as stated in the following table:
NOTE
Always use a fresh supply of alcohol and a clean container to prevent contamination by
dissolved material (from previous usage).
NOTE
Environmentally Preferred Products (EPP) (refer to the marking on the printed circuit
boards — examples shown below) were developed and assembled using environmen-
tally preferred components and solder assembly techniques to comply with the
European Union’s
Restriction of Hazardous Substances (ROHS) Directive 2002/95/
EC
and
Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
.
To maintain product compliance and reliability, use only the Motorola specified parts in
this manual..
