Resetting the Microcomputer

If the microcomputer may malfunction (unit cannot be operated,
or shows an erroneous display) if the power cord is unplugged
while the power is ON, or due to some other external factor. If this
happens, execute the following procedure to reset the micro­computer and return the unit to its normal operating condition.

Unplug the power cord from the wall outlet, then plug it
back in while holding down the POWER key.

• Please note that resetting the microcomputer will clear the contents
of the memory and returns the unit to the state it was in when it left the
factory.

With the power cord plugged in, turn the POWER key
OFF. Then, while holding down the ON/STANDBY key,
press POWER.

1. Push the BAND key for 2 seconds in the standby mode.

2. Display shows "F100/A10kHz" or "F50/A9kHz" blinkingly
for 5 seconds.

3. Turn the VOLUME knob (Encoder) to choose your chan­nel space.

4. Push the BAND key to memorize the channel space to
