HEADPHONE SET DESCRIPTION

For stand-alone functioning, your wireless headphones must be powered by rechargeable batteries (included). The rechargeable batteries must be installed into the battery compartment and recharged before use. (See Battery Installation and Information, page 6).

RECHARGING THE HEADSET

To recharge the headset unit, place the headphones into the recharging cradle/transmitter with the charge indicator facing the front. The headphones must be placed in a completely vertical position, not leaning to either side. If the headphones are placed correctly, the charge indicator light on the headphones illuminates.

RECHARGING CRADLE/TRANSMITTER

The recharging cradle/transmitter acts both as the transmitter of the signal to the headphones as well as the recharging base.

SUPPLIED ACCESSORIES

This headphone system includes accessories that enable you to use your wireless headphone set in several ways. (See sections on Standard Usage, page 8, and Alternate Installation Configuration, page 9).

BATTERY INSTALLATION AND INFORMATION

Your wireless headphone unit requires two rechargeable AAA batteries. 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 AAA rechargeable 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.

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 the recharging cradle/transmitter, with the charge indicator facing to 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 charge indicator light illuminates.
4. Subsequent charging must be performed in about 15-17 hours.

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 instead 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.
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 channels for radio frequency transmissions. Select one of these channels, using the switch on the back of the recharging cradle/transmitter.
6. After selecting a channel, use the fine-tuning control, located on the 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.
