INTRODUCTION

Your Optimus W ireless Stereo Head­phone System uses an infrared light
transmitter to send signals from an au­dio source (such as a TV or radio) to
special headphones equipped with a
built-in receiver. This frees you from
the tangle of headphone wire running
between your audio source and the
headphones.

You can use the system in your home
or office, up to 20 feet from the audio
source, and you can set the sound
level on each earpiece individually.

A specia l fea ture of this s yste m is t hat,
unlike many other cordless head­phones, it provides full stereo sound.
The system also allows you to re­charge the batteries without a battery
charger.

The system includes a transmitter, a
stereo headphone receiver, two re­chargeable AAA nickel-cadmium bat­teries, a Y-type phono plug adapter,
and an AC adapter.

PREPARATION

Before you can use your headphone
system, you must find a sui table loc a­tion for its transmitter, make the nec­essary transmitter connections, then
install and charge the headphone bat ­terie s .

PLACING THE
TRANSMITTER

The transmitter sends out an infrared
signal in a 30-degree, conical pattern.
Since infrared light rays travel in a
straight line, place the transmitter at
the same height or slightly higher than
the expected height of the headphone
receiver.

CONNECTING THE
TRANSMITTER TO YOUR
AUDIO SOURCE

You can connect the transmitter to
your audio source’s stereo headphone
jack or to separate left and right audio
output jacks (if av ailable). If you con­nect to audio output jacks, you can
use the headphone system’s volume
control to adjust the volume without
turning up your audio source.

To connect the transmitter t o your au­dio source’s stereo headphone jack,
insert the transmitter’s built-in
plug into the audio source’s
stereo headphone jack.

Notes:

• Since sunlight also con tains infra­red light, avoid placing the syst em
outdoors, near a window, or any
place where the light might pre­vent optimum transmission.

• Do not point the transmitter
directly toward a window. The
infrared signals do not reflect well
and reception might be poor.

• Do not place any object between
the transmitter and the receiver
that might block the infrared trans­mission.
