Sony STRDG720 Manual Do Utilizador

If there is a malfunction, the display shows a 
message. You can check the condition of the 
system by the message. Refer to the following 
table to solve the problem. If any problem 
persists, consult your nearest Sony dealer. 
If an error message appears while you perform 
Auto Calibration, see “Error and warning 
codes” (page 31) to solve the problem.

Irregular current is output to the speakers. 
The receiver will automatically turn off after 
a few seconds. Check the speaker 
connection and turn on the power again.

Clearing the receiver’s memory may remedy 
the problem (page 27). However, note that all 
memorized settings will be reset to their initial 
settings and you will have to readjust all 
settings on the receiver.

Consult your nearest Sony dealer. Note that if 
service personnel changes some parts during 
repair, these parts may be retained.
