Transmitter Range
The transmitter communicates with the headphones via an infrared (IR) light beam, so it is
important to maintain a direct line of sight between the transmitter and the headphones. Do not
obstruct the front of the transmitter in the area containing the IR emitters, as described above.
Because of the IR beam intensity, standing too close to the transmitter will overload the
headphone infrared receivers and shut off the headphone volume. For best reception,
stand between 4’ and 30’ from the transmitter.
Standing too close to
