ERROR MESSAGES
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 may be covered and the ventilation holes are blocked. Remove the object covering the ventilation holes
of the receiver.
The impedance of the connected speakers may be below the rated impedance range indicated on the back panel of
the receiver. Connect speakers whose impedance falls within the range.
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.
