PROTECTOR
The receiver will automatically turn off
after a few seconds, check the
followings:
• There may be 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 ventilation
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), let the receiver cool down for
30 minutes while troubleshooting the
followings:
– Disconnect all the speakers and
subwoofer.
– Check that the speaker wires are
tightly twisted on both ends.
– Connect front speaker first, increase
the volume level and operate the
receiver 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 that is
causing the protection error.
After checking 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.
