In case of difficulty
What seems to be a malfunction is not always so. Before calling for service, check the follow-
ing table according to the symptom of your trouble.
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 ON/STANDBY
key
depressed, plug the power cord again. This initializes the microcomputer. Note that this clears
the previously stored memory.
