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.
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.
