Troubleshooting

Problems and remedies

When the ?/1 indicator flashes

Immediately unplug the power cord and
check the following items.

• Are the system control cables connected

correctly?

• Are the + and – speaker cords short

circuited?

• Is the voltage selector set to the correct

voltage?
Check the voltage for your region, then
make sure the voltage selector is set
correctly.

• Are you using the supplied speakers?

• Is anything blocking the ventilation holes

on the rear of the system?

After checking the above items and fixing
any problems, plug in the power cord again
and turn on the system. If the ?/1

indicator

still flashes, or if the cause of the problem
cannot be found even after checking all the
above items, consult your nearest Sony
dealer.
