Important Note
•Wireless transmission means you can use these
speakers anywhere indoors without worrying
about things getting in the way. (Range: Up to
approx 20m*)
*Transmission distance varies depending on conditions of use.
•Distance specified in the product specification is
measured in a 2.4GHz friendly environment.
Distance may be reduced if the building structure
is made of metal material and there are multiple
2.4GHz wireless devices operating in the same
environment.
•When using the wireless speakers in a separate
room, thick or dense walls may reduce the 10 m
(30 ft) operating range.

4
•Because this system transmits signals at 2.4GHz,
sound may be interrupted if interference occurs.
This is due to radio frequency characteristics, and
it is NOT a malfunction.
•Any clicking noise hear through the speaker may
vary depending on the transmitter position and
room conditions. It is recommended that the
transmitter is placed in a location that produces the
clearest sound. Do not place the transmitter too
close to TV, AC power adaptor or any other
radiation sources.
•Do not place wireless speakers in a metal cabinet
or metal bookshelf.
•Sound may be interrupted if the transmitter is used
with other wireless apparatus using 2.4GHz
frequency, or a microwave oven.
