I When first applying power
Before first applying power, make sure all connections
required for your system are complete by referring to
Chapter 2. Then, reset the transceiver using the fol-
lowing procedure.
NOTE: When first applying power or when operat-
ing in cold environments, the display may flicker or
appear faint. This is normal and will disappear once
the transceiver has warmed up.
q Make sure the transceiver power is OFF.
w While pushing [M-CL] and [F-INP], push [POWER]
for 1 sec. to turn power ON.
• The internal CPU is reset.
• The transceiver displays its initial VFO frequency when
resetting is complete.
e Correct the set mode settings after resetting, if de-
sired.
Resetting CLEARS all programmed contents in
memory channels and returns programmed values
in set mode to default values.
