Servicing
Resetting the CPU
Resetting the CPU clears all memories, re­
peater shifts and other settings to their de­
faults, and leaves the transceiver CPU in the
same state as when it left the factory.
A soft reset can be done by holding the
D/MR and REV keys while switching the
transceiver on. If a CPU-related problem re­
mains after the soft reset, a hard reset can be
done as follows:
D
Turn the transceiver off, and disconnect all
cables.
D
Remove the top and bottom covers and the
front panel, as shown in
Case Disassembly on
page 1-2.
C5002
D Remove 15-.Q chip resistor R1031 from the
Main Unit.
D Temporarily short across capacitor C5002.
D Install another 15-.Q (chip or leaded) resistor
in the same place where R1031 was re­
moved.
D Replace the front panel and covers.
