Troubleshooting
The following table describes the possible malfunctions of this demvice, and the appropriate actions to be
taken in each case.
Problem Cause Action
Sound is no
longer out-
put from the
speakers.
The POWER
indicator is lit.
The load on the amplifier of this device
was too great, and the protection circuit
for the amplifier
has operated. Possible
reasons for the excessive load are an
excessive level setting in the channel
control section or main section, insuffi-
cient ventilation, or insufficient load
impedance of the connected speakers.
Please wait. When the device cools off, normal
operation will resume automatically. However,
please check the following three points to prevent
the problem from recurring.
If the level setting is excessive, lower it to the nomi-
nal level. You can refer to the peak level indicators
of the main section when doing so.
If the device is not ventilated sufficiently, refer to
the cautions given at the beginning of this manual
and take appropriate measures to insure adequate
ventilation.
If the load impedance (including a short) is too
low, refer to the chapter on rear panel (page 11)
and change the connections so that the impedance
is correct.
Other
Connections between devices have come
loose.
Inspect the connections, and correct any faulty
connections.
Other The device may have malfunctioned. Please contact
your dealer.
