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 headphones' receiver.

NOTES:  Since sunlight also contains infrared light, avoid placing the
        system outdoors, near a window, in a sun room, 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
        which might block the infrared transmission.

        An AM radio might interfere with the system's transmitting
        circuitry.  If this occurs, separate the system and the radio by a
        larger distance.

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 phono jacks.

To connect the transmitter to your audio source's stereo headphone jack,
simply insert the transmitter's built-in 1/8-inch plug into the audio
source's 1/8-inch stereo headphone jack.

To connect the transmitter to your audio source's audio output RCA jacks,
insert the supplied Y-type RCA plug adapter into the transmitter's built-in
1/8-inch plug, then connect the adapter to the audio source's left and
right audio output RCA jacks.

CONNECTING THE TRANSMITTER TO POWER

To power the transmitter, insert the supplied AC adapter's barrel plug into
the power jack on the back of the transmitter.  Then plug the adapter's
other end into a standard AC outlet.

WARNING:  To avoid shock hazard, do not leave the adapter plugged into the
          AC outlet when the barrel plug is not plugged into the
          transmitter.

CAUTION:  The supplied AC adapter supplies 18 volts and delivers at least
          200 milliamps.  Its center tip is set to negative and its plug
          correctly fits the transmitter's DC 18V jack.  Using an adapter
          that does not meet these specifications could seriously damage
          the transmitter or the adapter.

INSTALLING THE HEADPHONES' BATTERIES

To power the headphone receiver, you need two AAA batteries, one in each
earpiece.  For the best performance, we recommend alkaline batteries, such
as Radio Shack Cat. No. 23-555.

Follow these steps to install the batteries.

1.  To remove each battery compartment cover, push in the tab and pull up
    the cover in the direction of the arrow.

    NOTE:  If the battery indicator does not light or lights dimly when you
           set OFF/ON on the headphone receiver to ON, replace the
           batteries.

2.  Remove and discard the old battery (if necessary).

    CAUTIONS:  Never leave dead, old or weak batteries in the headphones.
               They can leak chemicals and corrode or damage electronic
               circuits.

               Always dispose of old batteries promptly and properly.

3.  Place one fresh AAA battery in each earpiece compartment, as indicated
    by the polarity symbols (+ and -) inside the compartment.

4.  Replace the covers.

NOTE:  If you do not plan to use the headphones for a month or more, remove
       and store the batteries.
