to prevent radio wave interference from other
equipment.
Precautions
Control reference guide
n Restriction of use
For use only in your country.
n Range of use
The range of use is up to approximately 30 m (98.4 ft.)
The range may be less depending on the structure
of the building, the environment and any obstacles
between the headphones and the transmitter.
Such obstacles as reinforced concrete walls and
metal doors, in particular, obstruct the transmitter’s
signals.
n Interference from other equipment
Due to radio interference, malfunctions such as
sound distortion may occur if the unit is placed too
close to other equipment. We recommend keeping
the unit as far away as possible from the following
devices.
Bluetooth devices, wireless LAN, microwaves,
offi ce automation devices, digital cordless
telephones and other electronic devices
The unit is designed to automatically avoid radio
interference from these household devices. However
the sound will be broken when radio interference
occurs. In this case reset the most appropriate
frequency (
page 14 [Setting the most appropriate
frequency]).
n Using the unit
● Do not drop, hit or otherwise subject the transmitter
or headphones to strong shocks of any kind. This
may damage them.
● Do not expose the unit to water or other liquids as it
may damage it.
