Troubleshooting guide
If a problem occurs while you are using the remote controller, first operate the unit using the front panel controls to confirm that it is not due
to a malfunction (or worn out batteries) of 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.
