Introduction

 

To perform most repairs, the unit must be
disassembled in order to gain access to the
various internal components. Reasonable
care should be taken in order to avoid
damaging or stressing the housing and
internal components. Motorola recommends
the use of a properly grounded high imped-
ance conductive wrist strap while
performing any of these procedures.

CAUTION

Many of the integrated circuit
devices used in this equipment
are vulnerable to damage from
static charges.   An anti-static
wrist band, connected to an
anti-static (conductive) work
surface, must be worn during all
phases of disassembly, repair,
and reassembly.

 

Recommended Tools

 

The following tools are recommended for
use during the disassembly and reassembly
of the StarTAC.

¥ Anti-Static Mat Kit (RPX-4307A);

includes:

Ñ Anti-Static Mat 66-80387A959

Ñ Ground Cord 66-80387A989

Ñ Wrist Band 42-80385A59

¥ Plastic Prying Tool SLN7223A

¥ Antenna Tool SYN5179A

¥ Tweezers

¥ Disassembly Fixture 8185677C02

 

Transceiver Disassembly

 

The preferred method for transceiver disas-
sembly is using the disassembly fixture.

Refer to page 17 for step by step instruc-
tions on using the disassembly fixture.

NOTE

Service personnel should be
familiar with all of the following
information before attempting
unit disassembly.
