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. After reconnecting, turn off and on the
unit and the connected device.
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.
∫ Resetting the unit (this resets the unit settings
to the default)
Resetting the unit to the status at the time of shipment may
solve the problem. If the unit is reset, your settings are
restored to the default values. Be sure to note down your

panel of the unit, then turn the unit on again. If this unit
does not turn on, 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

fields, such as those from a TV. Try moving any such
devices away from the integrated amplifier.
0 If you have any devices that emit high-intensity radio
waves near the integrated amplifier, such as a cellular
phone that's being used to make a call, the integrated
