Resetting the Microprocessors
Functional problems involving frequency,
mode and memory selection can sometimes be
resolved simply by resetting the microproces-
sors. There are two ways to reset the micro-
processors in the FT-890, both of which clear
the contents of all memories, leaving them at
the factory defaults.
Soft Reset
This procedure relies on a ROM routine
which should normally suffice to correct most
operating misfunctions. Turn the transceiver
off, then hold both the HAWGEN button and the
CLAR button while switching the transceiver
back on. If the problem persists, proceed to the
Hard Reset.
Hard Reset
© Turn the transceiver off, and then turn the
Backup switch (inside the hole near the
front center of the bottom cover) off.
© Let the transceiver sit for several minutes.
O Turn the transceiver on, then turn the
Backup switch back on (after the transceiver
has been turned on).
