The effective areas
of the transmitter
The illustration below shows the
approximate area covered by the
infrared rays emitted from the
transmitter.
Notes
•If you use the headphones at too great a
distance from the transmitter, you may hear a
hissing noise and if there is an object between
the receiver and the transmitter, the sound may
be interrupted. These phenomena are inherent
to infrared ray communication and do not
mean that there is a problem with the unit
itself.
•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 diagrams, the transmitter can
be placed in the front, behind or by the side of
the listener.
