BASIC OPERATION

■ When first applying power
Before first applying power, make sure all connections
required for your system are complete by referring to
Section 2. Then, reset the transceiver using the follow-
ing procedure.
Resetting CLEARS all programmed contents in
memory channels and returns programmed values
in set mode to default values.
q Make sure the transceiver power is OFF.
w While pushing [M-CL] and [(F-INP)ENT], push
[POWER] to turn power ON.
• The internal CPU is reset.
• A/D convertor calibration of the DSP unit starts and it
takes 10 sec.
• The transceiver displays its initial VFO frequencies when
resetting is complete.
e Correct the set mode settings after resetting, if de-
sired.

■ Initial settings

switches as shown in the figure below.
