BATTERY INSTALLATION AND INFORMATION
Your wireless headphone unit requires two rechargeable AAAbatteries.
The two rechargeable batteries that are supplied with your wireless
headphones are uncharged. Before you can use the wireless headphones,
the batteries must be charged. Follow these steps to charge and install
the batteries.
Installing the Rechargeable Batteries
Take care to follow these steps to correctly charge and install the batteries.
1. On the left earphone, locate the battery compartment and the word
“Open.” Use your fingernail in the groove on top of the battery
compartment to lift the cover.
2. Insert two AAArechargeable batteries (included), carefully following
the markings inside to ensure the batteries are inserted properly, with
the + and – ends in the correct positions.
3. Replace the battery compartment cover.
SUPPLIED ACCESSORIES
This headphone system includes accessories that enable you to use your
wireless headphone set in a number of ways. (See sections on Standard
Usage and Alternate Installation Configuration, page 9).
Stereo Y adapter cable
(RCA/3.5 mm jack) Main power adapter (AC/DC: 120 V ~ 60 Hz, 12 V = 200mA)

BATTERY INSTALLATION AND INFO (continued)
Charging the Rechargeable Batteries
Follow these steps to recharge the NiMH rechargeable batteries.
1. Connect the AC/DC main power adapter to the DC IN
power supply socket, located on the back of the recharging
cradle/transmitter.
2. Then, plug the adapter into an electrical outlet.
3. Place the headphones into recharging cradle/transmitter, with
the charge indicator facing to the front. Make sure the headphones
are placed in a completely vertical position, not leading to either
side. If the headphones are placed correctly, the charge indicator
light illuminates.
4. Subsequent charging must be performed in about 15-17 hours.
NiMH Rechargeable Battery Memory Effect
When an NiMH rechargeable battery is first used, it is important to fully
charge it and then allow it to discharge three times in order to maximize
the battery’s storage capacity. When a battery is recharged before
it is completely discharged, it develops a memory that will limit the
amount of charge in the future. This reduces the battery’s storage
capacity for subsequent charges and so reduces the amount of time
your headphones can be used before recharging is necessary.
NiMH Natural Power Discharge
Due to their chemical design, all rechargeable batteries incur some
degree of natural discharge. This means they automatically lose their
charge to in varying degrees, and the battery’s capacity drops even
when not in use. The size of this power loss varies, depending on the
battery’s type, size, design, internal resistance and, most especially, the
temperature. The higher the temperature, the greater the power loss
through natural discharge.
NiMH Battery Warning
1. To avoid risk of fire, explosion and injury, do not attempt to recharge
non-rechargeable batteries.
2. Respect the environment and the law. Before disposing of
rechargeable batteries, ask your distributor if they can be recycled
and whether or not the distributor collects rechargeable batteries
for recycling.

CONNECTING THE RECHARGING
CRADLE/TRANSMITTER
Follow this quick setup guide to ensure trouble-free installation of your
headphones. To connect the recharging cradle/transmitter to the audio
source, follow these steps.
1. Plug the stereo audio cable into the headphone jack of your audio
source (e.g., stereo, TV, CD player, DVD, etc.). If your audio source
has two RCA output jacks in place of a headphone jack, use the
supplied Y cable to connect your headphones to the two (red and
white) RCA jacks.
2. Connect the other end of the stereo audio cable to the AUDIO IN
socket at the back of the recharging cradle/transmitter.
3. Connect the AC/DC main power adapter to the DC IN power
supply socket at the back of the recharging cradle/transmitter. Then,
connect the adapter to an electrical outlet.
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 the audio input jack does not receive
an audio signal for approximately two minutes. If the volume on the
audio source is too low, the recharging cradle/transmitter also
switches off after two 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/earphones.
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 power on indicator light on the front of the
recharging cradle/transmitter is lit, indicating that the unit is ready.
4. Push the POWER ON/OFF button, located on the right earphone.
The LED light turns on to indicate activation.
5. The recharging cradle/transmitter features three phase lock loops
(PLL) for radio frequency transmissions. Select one of these channels,
using the switch on the back of the recharging cradle/transmitter.
WHP170_US_IB_REV.qxd 12/24/03 11:22 AM Page 9

10
OPERATION (continued)
6. After selecting a channel, use the fine tuning control, located on right
earphone to adjust the reception. The PLL function automatically
locks the three channels, providing you with top-quality audio
reception with no sound loss.
7. Adjust the volume using the volume control, also located on the
right earphone.
8. When you are through using the headphones, switch them off
using the POWER ON/OFF button, and place the audio source
on standby.
Note: To ensure that your headphones are charged and ready for
use at all times, place them in the recharging cradle/transmitter when
not in use.
Alternate Installation Configuration
The accessories included with your headphone system include a jack
adapter for connecting the unit to a 6.35 mm headphone socket and
a Y cable. Normally, when a device is plugged into a headphone jack,
it automatically shuts off the speakers. If you want the speakers to
continue playing while you are using the headphone set, you can use
the Y adapter instead of the headphone jack. Use the supplied Y cable
to connect your headphones to the two (red and white) RCA jacks.
Connect the other end of the stereo audio cable to the AUDIO IN input
jack at the back of the recharging cradle/transmitter. This is especially
useful if, for example, your family is listening to music in one room
of your home and you want to listen to the same music in another
room. It is also beneficial in families where one person has a hearing
impairment. That person can use the headphones to listen to the
audio source, adjusting the volume as needed. This type of connection
also enables you to use your headphones more simply as you will
only need to switch on the audio source and switch on your
headphones to activate.

TROUBLESHOOTING
Refer to this troubleshooting section if you encounter any difficulties in
setting up and using your headphones.
PROBLEM
No sound heard
through the
headphones
Poor sound quality
or interference
SOLUTION
A) Check that your audio source, recharging
cradle/transmitter and headphones are
connected, supplied properly and turned on.
B) Check to ensure that the rechargeable
batteries are installed in the headset
correctly and have been recharged properly.
C) Check to ensure the recharging cradle/
transmitter is running and the power
indicator light on the unit is lit.
D) Check that the audio source is delivering
a sufficient signal to the recharging cradle/
transmitter’s AUDIO IN input jack.
A) Check to ensure that the sound provided
by the audio source is loud enough and
of sufficient quality.
B) Check if the batteries in the headphones have
sufficient power. Recharge or replace them,
if necessary.
C) Check to see if you have selected the best
transmission channel (1, 2, or 3) to provide
the optimum signal reception. If necessary,
try another channel, remembering to fine-
tune the reception using the tuning control.
D) Check if the distance between the
headphones and the recharging cradle/
transmitter is within the operating range.
(The effective range of this device is up to
150 feet/45 meters from the cradle/
transmitter.)* Move closer to the recharging
cradle/transmitter to receive the sound.
E) Check that the audio source provides
stereo sound.
* Range may vary by environment.

TROUBLESHOOTING (continued)
PROBLEM
Power cut off
SOLUTION
The recharging cradle/transmitter has an
automatic power off function. When no signal
is received through the recharging cradle/
