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 isn't fixed after
referring to "Troubleshooting", resetting the unit to the
status at the time of shipment may solve the problem. Note
that your settings will also be initialized when you reset, so
we recommend that you note down your settings before
doing the following.
0 This unit 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.
0 We are not responsible for reparations 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.
If operation becomes unstable
Try unplugging the power cord of the unit and connected
devices, and then plugging them in again.
Resetting the unit (this resets the unit settings to the
default)
If the issue is not fixed by unplugging the power cord,
resetting the unit to the status at the time of shipment may
solve the problem. Your settings will also be initialized when
you reset, so note down your settings before doing the
following.
1. While holding down SPEAKERS A/B on the main unit,
press Í STANDBY/ON.
2. The unit switches to standby and the settings are reset.

speaker wires are not touching each other or the back
panel of the unit, then turn the unit on again. If "NG" is
displayed, immediately unplug the power cord from the
wall outlet and contact your dealer.
0 The protective circuit function may have been activated
because the temperature of the unit rose abnormally. If
this happens, then the power will continue to turn off after
you have turned the unit on again. Make sure the unit
has plenty of space for ventilation around it, wait for the
unit to cool down sufficiently, and then try turning it on
again.
