Positioning the Transmitter
The diagram below illustrates the approximate effective range of
the infrared rays emitted from the transmitter. Position the transmit-
ter so that your listening area is within the effective range.
The infrared rays will not
penetrate walis or opaque
glass, therefore the head-
phones must be used in
"in sight" area of the
transmitter.
