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 enter-
tainment system.
