Sony HT-SF470 User Manual

If an error message appears while you perform 
Auto Calibration, see “When error codes 
appear” (page 28) to solve the problem.

Clearing the receiver’s memory may remedy 
the problem (page 24). 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.
In the event of a problem with S-AIR function, 
have a Sony dealer check the entire system 
together (S-AIR main unit and S-AIR sub 
unit).
