Charging will start automatically.
If a beep sound is heard from the headphones
A repeated beep sound is heard if the processor is not turned on or if the headphones are
outside the RF signal transmission area. If you hear a beep sound, turn the processor on or
move closer to the processor and use the headphones in the RF signal transmission area. If the
beep sound does not stop even after turning the processor on or moving closer to the processor,
the cause is likely to be interference from, for example, another wireless device using the 2.4
GHz wireless frequency band or electromagnetic waves generated from a microwave oven. Try
taking the following measures.
Place the processor away from a device that generates electromagnet waves such as in a
location in which a wireless LAN or other wireless device or microwave oven is used.
Point the antenna of the headphones towards the antenna of the processor’s direction, and
make sure the signal is not blocked by any obstacles (page 21).
Change the installation location or position of the antenna of the processor, and move to a
location in which sound can be heard from the headphones.
Install the processor outside of a rack, do not install it at the back of a rack.
Install the processor in a location where no metal is present, do not install it on a metal table.
Move the processor and headphones as close as possible to each other.

US
Operation
RF signal transmission area
The approximate RF signal transmission area from the processor to the headphones is up
to 100 m but it varies depending on whether obstacles (human body, metal, wall, etc.) are
present and the reception conditions.
The antennas of this system are built into the parts indicated by the dotted lines in the
illustration below.
Location of built-in
antenna
If there are any obstacles between the antenna part of the processor and the antenna part of
the headphones, the signal transmission range may become shorter. In such a case, ensure no
obstacles are between the antennas of the processor and headphones.
The sound may be interrupted if you move out of the signal transmission range or the
reception conditions around you deteriorate during use. The sound may also be interrupted
as a result of obstacles, installation location or positioning of the processor and orientation of
the headphones. This phenomenon is due to the characteristics of RF signals, and is not an
indication of a malfunction.
Notes
This system uses a signal in the 2.4 GHz frequency band so use under the following conditions may affect
the signal transmission range.
An obstacle such as a human body, metal, or wall is between the processor and headphones.
The processor is installed at the back of a rack.
In a location in which a wireless LAN has been built, in a location in which a microwave oven is used
nearby or other electromagnetic waves are generated, etc.
In a location in which another wireless device uses the 2.4 GHz frequency band.
This system and a wireless LAN (IEEE802.11b/g) use the same frequency band (2.4 GHz) so use near a
device incorporating a wireless LAN function will result in the generation of signal interference, which
may cause the communication speed to deteriorate, and noise or sound interruption. In such a case, take
the following measures.
When using the system within 10 m from a device incorporating a wireless LAN function, turn the
wireless LAN function off.
Move the processor and headphones as close as possible to each other.
Do not install the processor near metal objects such as on a metal table.
The sound may be interrupted if the signal of this system is blocked by an obstacle. This phenomenon is
due to the characteristics of RF signals, and is not an indication of a malfunction.

If an audio signal is not input for about 30 mins
RF signal transmission from the processor automatically stops when an audio signal is not
input for about 30 minutes. When the transmission stops, the processor’s power indicator
blinks in green for 30 seconds and then turns off. RF signal transmission may stop when an
extremely low sound is input for about 30 minutes. If this happens, raise the volume of the
connected AV component as high as possible to the extent that the sound is not distorted and
lower the volume of the headphones. If signal noise is output from a component connected to
the AUDIO IN jacks, RF signal transmission may not stop.
If the processor is turned off
The headphones will turned off automatically after 5 minutes. When you want to use the
system again, turn the headphones and processor on.
If you move out from the signal transmission range, the headphones cannot be connected to
the system, and will turn off automatically after 5 minutes.
Note
The processor only works with its supplied headphones.
