About $·AIR function
• As the S-AIR function 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 function transmits sound by radio
waves, equipment that generates electromagnetic
energy, such as a microwave oven, may interfere with
sound transmission.
• As the S-AIR function uses the radio waves that share
the same frequency as other wireless systems, such as
wireless LAN or Bluetooth, interference or poor
transmission may result. In this case, take the
following steps:
- Do not install the system near other wireless·
systems.
- Do not use the system and the other wireless
systems at the same time.
• 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.
