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 restarting the unit

switching this unit to standby, press and hold Í ON/
STANDBY on this unit for 5 or more seconds to restart the

fixed by restarting, try unplugging the power cords of the
unit and connected devices, and then plugging them in
again.

default)
