Operation to reset
The microcomputer may fall into malfunction when a cord is unplugged and plugged again
while the unit is ON or due to an external cause. In such a case, the microcomputer should
be reset as described below:
Unplug the power cord from the wall outlet and, while holding the REPEAT key
depressed, plug the power cord again. This initializes the microcomputer. Note that
this clears the previously stored memory.
Remedy
= Increase the volume level (page 12).
= Unplug the headphones if they are connected (page 9).
= Check if the headphone plug is inserted properly into the
jack (page 9).
= Install the outside antenna more apart from the streets
(page 9).
= Turn nearby electrical appliances off.
= Install the audio system more apart from the TV set.
