Overview

This section explains, step by step, how to disassemble

and reassemble the GTX/GTX LTR/LTS 2000 radios.

Safety Information

When testing and repairing the GTX/GTX LTR/LTS

2000 radios, observe the handling precautions to pre-

vent unnecessary damage to the GTX/GTX LTR/LTS

2000 radios.

• Minimize handling of static-sensitive compo-

nents and modules.

• Transport and store static-sensitive components

or assemblies in their original containers on a

metal rail. Label any package that contains

static-sensitive components or assemblies.

• Discharge static electricity from the body by

wearing a grounded antistatic wrist strap while

h a n d l i n g t h e s e c o m p o n e n t s . S e r v i c i n g

static-sensitive components or assemblies

should only be done at a static-free work station

by qualified service technicians. Increasing the

humidity in the work area minimizes static elec-

tricity problems.

• Do not allow anything that can generate or hold

a static charge on the workstation surface.

• Keep the component leads shorted together

whenever possible.

• Pick up components by their bodies. Never pick

them up by their leads.

• Do not slide the components over any surface.

• Avoid handling components in areas with a

floor or work surface covering that can generate

a static charge.

• Use a soldering iron connected to earth ground.

• Use only approved, anti-static, vacuum-type

desoldering tools for removing components.

• When removing printed circuit boards (PCBs),

remove the screws in a diagonal pattern to

reduce stress on the boards.
