Station modules suspected of being faulty must be replaced with
modules known to be in good condition in order to restore the station
to proper operation. The following procedures provide instructions
for replacing each of the station modules and performing any
required post-replacement adjustments or programming.
The station circuitry contains many C-MOS and other static-
sensitive devices. When servicing the equipment, you must take
precautionary steps to prevent damage to the modules from static
discharge. Complete information on prevention of static protection
is provided in Motorola publication number 68P81106E84,
available through the Accessories and Aftermarket Division.
Some additional precautions are as follows:
• A wrist strap (Motorola part number RSX4015A,
or equivalent) should be worn while servicing the
equipment to minimize static buildup.
