If you experience any of the following
difficulties while using the system, use this
troubleshooting guide to help remedy the
problem before requesting repairs. Should any
problem persist, consult your nearest Sony
dealer. When bringing the system in for repairs,
be sure to bring in the entire system.
When you install the S-AIR sub unit (optional),
in the event of a problem with the S-AIR
function, have a Sony dealer check the entire
system together (main unit and S-AIR sub unit).

Press ?/1 to turn off the system, and check
the following item after “STANDBY”

cause of the problem still cannot be found,
consult your nearest Sony dealer.

back to the input you want to check. If
“2.0ch” or “1.0ch” is displayed in the front

is set to between [10 ms] and [200 ms].
