Troubleshooting—Continued

Remote Controller

The remote controller doesn’t work?

•Make sure that the batteries are installed with the cor- rect polarity (page 9).

•Make sure that the remote controller is not too far away from the AV receiver, and that there’s no obstruction between the remote controller and the AV receiver’s remote control sensor (page 9).

•Make sure you’ve selected the correct remote control- ler mode (page 10).

•Make sure you’ve entered the correct remote control code.

Can’t control other components?

•Make sure you’ve selected the correct remote control- ler mode (page 10).

•To control Onkyo cassette tape deck, point the remote controller at the AV receiver.

•To control Onkyo CD player, MD/CD recorder, point the remote controller at that component.

Recording

Can’t record?

•On your recorder, make sure the correct input is selected.

•To prevent signal loops and damage to the AV receiver, input signals are not fed through to outputs with the same name (e.g., TAPE IN to TAPE OUT, or VIDEO 1 IN to VIDEO 1 OUT).

Others

The sound changes when I connect my head- phones?

•When a pair of headphones is connected, the listening mode is set to Stereo, unless it’s already set to Stereo, Mono or Direct.

How do I change the language of a multiplex source?

•Use the “Multiplex” setting on the “4. Audio Adjust” menu to select Main or Sub (page 45).

The functions don’t work?

•To use , you must make an connection and an analog audio connection (RCA) between the compo- nent and AV receiver, even if they are connected digi- tally (page 29).

The AV receiver contains a microcomputer for signal pro- cessing and control functions. In very rare situations, severe interference, noise from an external source, or static electricity may cause it to lockup. In the unlikely event that this happens, unplug the power cord from the wall outlet, wait at least five seconds, and then plug it back in again.

Onkyo is not responsible for damages (such as CD rental fees) due to unsuccessful recordings caused by the unit’s malfunction. Before you record important data, make sure that the material will be recorded cor- rectly.

To reset the AV receiver to its factory defaults, turn it on and, while holding down the [VIDEO 1/VCR] button, press the [STANDBY/ON] button. “Clear” will appear on the display and the AV receiver will enter Standby mode.

Before disconnecting the power cord from the wall out- let, set the AV receiver to Standby.
