The AV receiver contains a microPC 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 happens, unplug the power cord from the wall outlet,
wait at least 5 seconds, and then plug it back in.
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.
Before disconnecting the power cord from the wall outlet,
set the AV receiver to standby.
