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 POWER
key depressed,
plug the power cord again. This initializes the microcomputer. Note that this clears the
previously stored memory.
