Handling 
Precautions
Complementary metal-oxide semiconductor (CMOS) devices, and other high-
technology devices, are used in this family of radios. While the attributes of 
these devices are many, their characteristics make them susceptible to damage 
by electrostatic discharge (ESD) 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 this 
radio, and are especially important in low-humidity conditions. 
At this time, troubleshooting and repair of the radio will not be supported by 
the field or self-maintained customer. DO NOT attempt to disassemble the 
radio.
