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.
Also refer to the respective instruction manuals of the video disc player, video cassette recorder, TV monitor, etc.,
that compose your entertainment system.
Because the unit contains a microcomputer to provide advanced functions, it may malfunction due to external noise or
static electricity. If this happens, press the Power switch on the unit and then press it in again after about five seconds.
