Maximum Performance
When the audio source offers a variable volume output, maximum
performance can be achieved. Variable volume outputs include
headphone jacks, computer speakers and some TV RCA output jacks.
Va ri a bl e Vo l um e O u tp u t. When using an audio source with a variable
output jack, you can reduce any distortion and achieve maximum
performance by following these steps:
1. Set the volume of the audio source component to mid-level.
2. Adjust the headphone VOLUME control (6) until the desired result
is achieved.
3. If the headphone volume is not suf cient, adjust the source volume.
4. If distortion occurs, reduce the volume on the source component.
Fixed Volume Output. When using an audio source with a xed
volume output, regulating the volume can be achieved through the
headphone VOLUME control (6) only. Examples of xed volume
outputs are RCA jacks (VCR, Tape, Video or CD outputs).
TROUBLESHOOTING
Refer to this troubleshooting section if you encounter any dif culties
in setting up and using your headphones.
PROBLEM SOLUTION
No sound heard • Check that your audio source, cradle/transmitter and
through the headphones are connected, supplied properly and
headphones turned on.
Check to ensure that the rechargeable batteries are
installed in the headset correctly and have been
recharged properly.
Check to ensure the cradle/transmitter is running
and the audio signal LED indicator light (9) on the
unit is lit.
Check that the audio source is delivering a suf cient
signal to the cradle/transmitter through the audio
input cable (13). Use the VOLUME control (6) to
increase the sound level.
• Check to ensure the audio outputs of your TV are “live”
when you are connecting to the stereo audio outputs
(RCA jack). You may need to go into the TV menu
system to ensure these outputs are turned on. Refer to
your TV user manual for more details.
Check that the headphone and transmitter are set
to the same channel.

OPERATION
Standard Usage
1. Switch on the audio source (TV, DVD, CD player, etc.) to which the
cradle/transmitter is connected. If your audio source is a DVD or
CD player, start a disc.
Warning: The cradle/transmitter has an automatic function that
switches it off if it does not receive an audio signal for approximately
4 minutes. If the volume on the audio source is too low, the cradle/
transmitter also switches off after four minutes. This feature
was installed to comply with current legislation that reduces the
amount of radio emissions in the environment. To ensure that this
function is not accidentally triggered, set the audio source volume at
approximately 50 percent capacity. Consult your component user’s
manual for details on how to set the volume for headphones.
2. The cradle/transmitter is now ready to receive an audio signal. The
cradle/transmitter is activated automatically when receiving an
audio signal from the audio source.
3. Check to make sure the audio signal LED indicator light (9) on the
front of the cradle/transmitter is lit, indicating that the unit is ready.
4. Place the headphone ON/OFF switch (2), located on the right
headphone, to the ON position.
5. Check to make sure the stereo LED indicator light (5) on the left
headphone is lit, indicating a strong signal.
6. The cradle/transmitter and the headphones feature double phase
lock loops (PLL) for radio frequency transmissions. Select one of
the three channels on the back of the cradle/transmitter (12) and
the corresponding channel on the left headphone (7). Be sure
that the same channel (1, 2 or 3) is selected on both the cradle/
transmitter and the headphones. The Phase Lock Loop (PLL)
function automatically locks the chosen channel, providing
top-quality audio reception with no sound loss.
7. Before wearing headphones adjust the volume using the VOLUME
control (6), located on the left headphone, to a comfortable volume
level.
8. When you are through using the headphones, switch them off using
the ON/OFF switch (2), and place the audio source on standby.
