INSTALLATION
Note that when the audio device is on, the green “SIGNAL
INDICATOR” LED light will glow (green). This indicates that the
transmitter is receiving an adequate audio signal. If the LED is not on,
you must increase the volume until the green LED is lit. If you
increase the volume and the LED still does not illuminate, then check
all your connections and make sure that the power is on for both the
device and the transmitter. Refer to the section titled
“Troubleshooting” located on page 8 of this instruction book for
assistance.
TRANSMITTER
1. Slip the antenna tube over the antenna wire located on the back.
2. Plug the AC power adapter into the DC jack located on the rear of
the transmitter.
3. Connect the AC power adapter to an electrical wall outlet.
4. The audio cord on the rear of the transmitter can be connected to
the audio output jack (R & L) of the TV, stereo receiver, VCR, DVD
or radio.
•Use a Y Splitter for R & L type RCA connections.
5. Turn on the component device.

OPERATION
HEADPHONE RECEIVER
1. Open the battery compartment cover on the right side of the
headphone receiver.
2. Insert two AAA size rechargeable batteries, noting the correct polarity
as indicated in the battery compartment.
3. Replace the cover by sliding it in place until it “snaps” into position.
4. The batteries must now be charged before you use the headphones.
Refer to the instructions on page 6 “Charging the Batteries” for
details.
1. Turn on the audio source (TV or audio component) to which the
transmitter is connected.
2. Slide the ON/OFF switch on the headphone to “ON.”
3. Listen to the volume coming from the ear cups on the headphone to
make certain that the volume is not too loud before placing the unit
on your head. (See the section titled “Headset Safety” on page 1.)
Adjust the volume as needed using the VOLUME CONTROL wheel
located on the left ear cup. Once the volume level is at a comfortable
setting, place the headphones over your ears and adjust the volume
as desired.
4. If the best frequency reception is not found, press the “Auto Scan”
button on the headphone to locate the frequency of the transmitter
for the best reception. The stereo LED indicator will light up.
The headphone may be operated by
using standard or alkaline batteries.
However, these may not be recharged in
the headphone. Standard zinc carbon,
manganese or alkaline batteries
may leak or explode if recharged in
the headphone, thereby voiding
the warranty. Do not attempt to
recharge any batteries in the head-
phone other than nickel cadmium
type cells that were included with
your unit.

NOTE
You should now be able to walk freely from room to room enjoying full
stereo sound. If you notice interference (noisy signal or if the sound is
distorted or breaks up), adjust the frequency by turning the thumb
wheel control located on the front of the transmitter base either left or
right. Then, push the “Auto Scan” button on the headphone to lock into
the new frequency. This should help you to obtain better reception with
the headphones. You may have to try this adjustment several times to
obtain optimum performance, depending on the conditions. Please refer
to the following drawings A and B for best tuning:
A
Keep a distance of about 20 feet between the headphone and the
transmitter when adjusting the tuning knob for best stereo reception.
For protection of the transmitter and to save power, the transmitter
will cut off automatically after about one minute when the input
signal from an audio source is too weak for operation. If the signal
from the audio source returns at a sufficient level, the transmitter will
turn on again automatically.
5
B
Whenever you find interference, readjust the frequency of the
transmitter by turning the thumb wheel and then pushing the
“Auto Scan” button on the headphone to lock in a new frequency.

batteries for 24 hours prior to the first use of the headphone system.
Caution : Do not use other types of batteries to replace the rechargeable
(AAA) battery. When you are not using the headphone
receiver, please switch it to OFF to avoid damage to the
batteries.
