Troubleshooting

If you have any trouble using the AV receiver, look for a solution in this section. If you can’t resolve the issue yourself, contact the dealer from whom you purchased this unit.

If you can’t resolve the issue yourself, try resetting the AV receiver before contacting the dealer from whom you purchased this unit.

To reset the AV receiver to its factory defaults, turn it on and, while holding down the [VCR/DVR] button, press the [Standby/On] button.“Clear” will appear on the display and the AV receiver will enter Standby mode.

Note that resetting the AV receiver will delete your radio presets and custom settings.

Power

Can’t turn on the AV receiver

•Make sure that the power cord is plugged into the wall outlet properly.

•Unplug the power cord from the wall outlet, wait 5 seconds or more, then plug it back in again.

The AV receiver turns off as soon as it’s turned on

•The amp protection circuit has been activated. Remove the power cord from the wall outlet immedi- ately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord discon- nected for 1 hour. After that, reconnect the power cord and set the volume to maximum. If the AV receiver stays on, set the volume to minimum, disconnect the power cord, and reconnect your speakers and input sources. If the AV receiver turns off when you set the volume to maximum, disconnect the power cord, and contact the dealer from whom you purchased this unit.
