OPERATION

Standard Usage

1. Switch ON the audio source (TV, DVD, CD player, etc.) to which the
recharging cradle/transmitter is connected. If your audio source is a
DVD or CD player, start a disc.
Warning: The recharging cradle/transmitter has an automatic
function that switches it off if it does not receive an audio signal
for approximately four minutes. If the volume on the audio source
is too low, the recharging cradle/transmitter also switches off after
4 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 recharging cradle/transmitter is now ready to receive an audio
signal. The recharging 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 recharging cradle/transmitter is lit, indicating
that the unit is ready and is receiving a signal.
4. Place the headphone ON/OFF switch (2), located on the right
headphone, to the ON position.
5. The recharging cradle/transmitter features Phase Lock Loop (PLL)
for radio frequency transmissions. Select one of these channels,
using the CHANNEL switch (12) on the back of the recharging
cradle/transmitter. The PLL function automatically locks the chosen
channel, providing top-quality audio reception with no sound loss.
6. After selecting a channel, press the AUTO SCAN button (7), located
on the left headphone, to search for best reception.
Note: For best reception, stay approximately 23 feet away from the
recharging cradle/transmitter when pressing the AUTO SCAN
button.
7. Check to make sure the stereo LED indicator light (5) on the left
headphone is lit, indicating a strong signal.
8. Before wearing headphones adjust the volume using the VOLUME
control (6), located on the left headphone, to a comfortable volume
level.
9. When you are through using the headphones, switch them off using
the ON/OFF switch (2), and place the audio source on standby.

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.
Variable Volume Output. 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 sufficient, 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 fixed
volume output, regulating the volume can be achieved through the
headphone VOLUME control (6) only. Examples of fixed volume
outputs are RCA jacks (VCR, Tape, Video or CD outputs).
