Problems and remedies

Should you encounter a problem with your

system, do the following:

Make sure the power cord and speaker

cords are correctly and firmly connected.

Find your problem in the troubleshooting

checklist below and take the indicated

corrective action.

If the problem persists after doing all of the

above, consult your nearest Sony dealer.

In case of repairing, please bring the entire

system set (except for the speaker) to the service

station.

When the ?/1 indicator flashes

Immediately unplug the power cord and

check the following items.

• Are the system control cables connected

correctly?

• If your system has a voltage selector, 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 the + and – speaker cords short-

circuited?

• Are you using the supplied speakers?

• Is anything blocking the ventilation holes

on the rear of the system?

Check all the above items and fix any
