BATTERY INSTALLATION AND INFORMATION

Your wireless headphone unit requires two rechargeable AAA batteries.
Rechargeable batteries are uncharged when you purchase them. Before you
can use the wireless headphones for the first time, the batteries must be
charged for 16 hours. Follow these steps to install and charge the batteries.

Installing the Rechargeable Batteries

Take care to follow these steps to correctly install the batteries.
1. On the right headphone, locate the battery compartment (1). Turn the
battery compartment cover counterclockwise to remove the cover.
2. Insert two AAA rechargeable batteries, 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.

Charging the Rechargeable Batteries

Follow these steps to recharge the NiMH rechargeable batteries.
1. Make sure the ON/OFF switch (2), located on the right headphone,
is in the OFF position.
2. Connect the AC/DC main power adapter to the DC IN power supply
socket (10), located on the back of the recharging cradle/transmitter.
3. Plug the adapter into an electrical outlet.
4. Place the headphones into the recharging cradle/transmitter, with
the power LED indicator light (4) facing the front. Make sure
the headphones are placed in a completely vertical position, not
leaning to either side. If the headphones are placed correctly, the red
charging LED indicator lights on the recharging cradle/transmitter
(8) illuminate.
5. Charge the rechargeable batteries for 16 hours before using the
headphones for the first time.
6. Battery charges last approximately eight hours before recharging is
necessary.

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. Avoid recharging the battery until it is
fully discharged. 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.

BATTERY INSTALLATION AND INFORMATION

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 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

If you are using NiMH or NiCd batteries, the batteries will charge when
the headphones are powered with the AC power adapter. Do not power
the headphones with the AC power adapter if you installed alkaline or
other non-rechargeable batteries—this could cause the batteries to leak. Do
not mix batteries with different chemistry types (for example, a zinc
battery with an alkaline battery). Do not mix new and used batteries. Do
not leave batteries installed in the product when not in use for long
periods. 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. Connect the AC/DC main power adapter to the DC IN power
supply socket (10) at the back of the recharging cradle/transmitter.
Then, connect the adaptor to an electrical outlet.
Important: This power unit is intended to be correctly oriented in a
vertical or floor mount position.
2. Plug the stereo audio cable into the headphone jack of your audio
source (e.g., stereo, TV, CD player, DVD, etc.).
3. Connect the other end of the stereo audio cable to the Left and
Right AUDIO inputs (11) on the cradle/transmitter. The green audio
signal LED indicator light (9), located on the front of the recharging
cradle/transmitter, illuminates as soon as you have connected the
power adapter to the outlet and when an audio signal is detected by
the recharging cradle/transmitter.
