On cleaning
• Clean the cabinet, panel, and controls with a
soft dry cloth. Do not use any type of
abrasive pad, scouring powder, scrubbing
brush or sponge.
• If it is stained with oil or fingerprints, breath
on the surface and wipe it with soft dry cloth.
On S-AIR function
• As the S-AIR product(s) transmits sound by
radio waves, sound may skip when radio
waves are obstructed. This is a characteristic
of radio waves and is not malfunction.
• As the S-AIR product(s) transmits sound by
radio waves, equipment that generates
electromagnetic energy, such as a
microwave oven, may interfere with sound
transmission.

• As the S-AIR product(s) uses the radio
waves that share the same frequency as other
wireless systems, such as wireless LAN or
Bluetooth device, interference or poor
transmission may result. In this case, take
the following steps:
– Avoid placing the S-AIR product(s) near
other wireless systems.
– Avoid using the S-AIR product(s) and the
other wireless systems at the same time.
– The transmission may be improved by
changing the transmission channel
(frequency) of the other wireless
system(s). For details, refer to the
operating instructions of the other wireless
system(s).
• 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 table
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 store 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 system, please consult your
