Onkyo TX-SR8550, SR575, TX-SR505E instruction manual Troubleshooting-Continued, Memory Backup

Troubleshooting—Continued

The AV receiver contains a microcomputer for signal processing and control functions. In very rare situa- tions, 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.

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

Memory Backup

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. Once it has been charged, the AV receiver will retain the settings for several weeks, although this depends on the environment and will be shorter in humid climates.
