Error messages
If there is a malfunction, a message appears on
the display panel. You can check the condition
of the system by the message. If any problem
persists, consult your nearest Sony dealer.
PROTECTOR
The receiver will automatically turn off
after a few seconds. Check the followings:
There may be an electrical surge or
power failure. Unplug the AC power cord
(mains lead) and then plug in the cord
again after 30 minutes.
The receiver is covered and the ventila-
tion holes are blocked. Remove the object
covering the ventilation holes of the
receiver.
The impedance of the connected speakers
is below the rated impedance range
indicated on the back panel of the
receiver. Reduce the volume level.
Unplug the AC power cord (mains lead)
and let the receiver cool down for 30
minutes while performing the following
troubleshooting:
– Disconnect all of the speakers and
subwoofer.
– Check that the speaker wires are tightly
twisted on both ends.
– Connect the front speaker first, increase
the volume level and operate the
receiver for at least 30 minutes until
it completely warms up. Then, connect
each additional speaker one by one and
test each additional speaker until you
detect which speaker is causing the
protection error.
After checking the above items and fixing
any problems, plug in the AC power cord
(mains lead) and turn on the receiver. If
the problem persists, consult your nearest
Sony dealer.
USB FAIL
