If you have a games console connected to a compo-
nent video, S-Video or composite video input, and
the picture isn’t very clear, you can attenuate the

Video ATT:2: Gain is reduced by 2 dB.
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.
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.
