Since the issue may be caused by other components that are connected, be sure to also check them while referring to their manuals.
- 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 correctly.
- The integrated amplifier contains a microcomputer for signal processing 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 should happen, unplug the power cord, wait at least 5 seconds, and then plug it again.
- Before disconnecting the power cord from the wall outlet, set the integrated amplifier to Standby.
- If during idling the cover is too hot to touch, then ventilation needs to be improved.

amplifier is set to the correct setting.
- The settings are not enabled when the switch is changed
during the Standby mode.
To change a setting, be sure to turn on the unit prior to
making any changes.
- If this unit is being used as a power amplifier and input is
switched to "MAIN IN", then if the volume of the
connected pre-amplifier is low, auto standby
may function and the power may automatically switch to
standby. If this happens, you may be able to fix it by
increasing the volume on the pre-amplifier.
