Resetting The Cpu - Yaesu FT-5100 Technical Supplement

Resettin g 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 Disassembl y on
page 1-2.
