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 35).

During automatic speaker setup, measurement fails and the message “Noise Error!” appears

•This can be caused by a speaker malfunction. Make sure all of your speakers are working properly.

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.

If you use this product under direct sunlight, fluorescent light, or germicidal lamp, ultraviolet or another elements in the light may change the product exterior color.

•The operating instructions in this manual apply to the iPod as of June 2007, and may change with future upgrades to the iPod software.

•The AC adapter supplied with the DS-A1X is designed exclusively for use with the DS-A1X. Do not use it with another device. Likewise, do not use any other AC adapter with the DS-A1X, including those supplied with other RI Dock models. Doing so may damage the AV receiver.

•If there’s any noise when listening to an FM or AM radio station on your tuner or receiver, try moving its antenna away from the AV receiver, iPod, and AC adapter’s cable. In addition, don’t wrap the AC adapter’s cable around any other cables.
