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.
The following settings can be made for the
S-Video and composite video inputs
You must use the buttons on the unit to make these set-
tings.
1. While holding down the input selector button for the
input source that you want to set, press the [SETUP]
button.
2. Use the Left and Right [
the setting.
3. Press the [SETUP] button when you've finished.
• Video Attenuation
This setting can be made for the DVD, VIDEO 1,
VIDEO 2, or VIDEO 3 input.
If you have a games console connected to an S-Video
or composite video input, and the picture isn't very
clear, you can attenuate the gain.
Video ATT:0: (default).
Video ATT:2: Gain is reduced by 2 dB.
