1. Switch on the (IR) transmitter and position it in a location at
approximately the same height as that of the headphone when
it will be in use. This system operates using IR light signals
that are invisible to the human eye. It is important for the per-
formance of the unit to have the transmitter and headphone at
about the same height for optimum reception. Placement on top
of a TV or bookshelf at a height of approximately 4 feet should
be sufficient.
2. Make certain that there are no obstructions that may block the
IR signals that are emitted from the translucent plastic window
on the front of the transmitter. The headphone must receive
these signals clearly for best performance.
3. Slide the switch on the headphone to “ON”.
4. Before placing the headphone over your ears, listen to the
volume from the earcups to make certain that the volume is not
too loud before placing the unit on your head (see page 2).
Adjust the volume as needed with the volume control thumb
wheel located on the “RIGHT” earcup. Once the volume level is
at a comfortable setting, place the headphones over your ears
and adjust the volume as desired.
