Troubleshooting - Sony HT-SF470 Operating Instructions Manual

• The transmission distance differs depending
on the usage environment. Find a location
where transmission between the S-AIR main
unit and sub unit is most effective, and
install the S-AIR main unit and sub unit
there.
• Place the S-AIR product(s) on the stable
surface off the floor.
• Poor transmission may occur and the
transmission distance may be too short if the
following conditions exist:
– There is a wall/floor made of reinforced
concrete or stone between the S-AIR
product(s).
– There is an iron divider/door or furniture/
electric product made of fireproof glass,
metal, etc., between the S-AIR product(s).
If you have any questions or problems
concerning your receiver, please consult your
nearest Sony dealer.
