Troubleshooting guide
If a problem occurs while you are using the remote controller, first try to operate the front panel controls on the main unit to make sure that it
is not due to a malfunction (or worn out batteries) in the remote controller.
This stereo system contains a sensitive microcomputer, which under certain circumstances might fail to operate due to excessive noise inter-
ference. In such an event, disconnect the AC power from your electrical outlet and replace it 5 seconds later.
•
Also refer to the respective instruction manuals of the video disc player, video cassette recorder, TV monitor, etc., being used.
