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.

Resetting the AV receiver to its factory defaults

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

The AV receiver uses a battery-less memory backup system in order to retain radio presets and other set- tings when it’s unplugged or in the case of a power fail- ure. Although no batteries are required, the AV receiver must be plugged into an AC outlet in order to charge the backup system.

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