Resetting the Microcomputer
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 microcom-
puter 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 ON/STANDBY 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.

or more, the following settings will be reset to the initial condi-
tions. Please be careful.

Broadcast band = FM
Frequency setting = 87.50 MHz
