Chapter 6 Basic Troubleshooting
6.1 Introduction
This chapter contains error codes and board replacement procedures. If the board does not pass all
the performance checks in Chapter 3 or exhibits an error code listed below, then the circuit board
should be replaced. If repair requires knowledge of details of component level troubleshooting,
please send radio to a Motorola Service Center or Motorola Authorised Dealers.
6.2 Replacement Back Cover Kit Procedures
If the Back Cover Kit is replaced, it does not necessarily need to be retuned if it has been factory
tuned. It should however be checked for performance before placed into service. Of particular
concern is the Bias DAC, which will need to be set for the appropriate final device bias current prior
to keying up the radio. Of the bias is not set it may be possible to cause damage to the transmitter.
NOTE
To access the various connector pins, use the housing eliminator/test fixture along with the
diagrams found in this section of the manual. (See the section, "Service Aids" on page 2-2,
for the appropriate Motorola service aids and tools parts numbers.)
Only Motorola Service Centers or Authorised Motorola Service Dealers can
