Troubleshooting
Before starting the procedure
Problems may be solved by simply turning the power on/off or disconnecting/
connecting the power cord, which is easier than working on the connection,
setting and operating procedure. Try the simple measures on both the unit and
the connected device. If the problem is that the video or audio is not output or
the HDMI linked operation does not work, disconnecting/connecting the HDMI
cable may solve it. When reconnecting, be careful not to wind the HDMI cable
since if wound the HDMI cable may not fit well. After reconnecting, turn off and
on the unit and the connected device.
• 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.
• Our company 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.
