Notes
•This system utilizes infrared rays for
communication so noise (hissing) can be heard
from the headphones as you move farther away
from the transmitter. The sound will also be
cutoff and noise will be heard if the infrared
rays are blocked. These are characteristics of
infrared ray communication and do not
indicate malfunction.
•The infrared rays will not penetrate walls or
opaque glass, therefore, be sure to stay within
sight of the transmitter.
•When you use the headphones inside the area
illustrated in the diagram, the transmitter can
be placed in the front, behind or by the side of
the listener.
•The sound you hear varies according to your
position and the transmitter position. Try
finding a position which yields the best sound.
•Do not cover the infrared sensors with your
hands or hair.
