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.

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 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.

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 in varying degrees, 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 retailer if they can be recycled and whether or not the retailer collects rechargeable batteries

for recycling.
