Operation

The Dual Battery Charger is designed to charge one Battery Pack at a time. Each charging slot has a red light that indicates its current mode. The charging lights have the following characteristics:

When both a Battery Pack and a Wireless Telephone are present at the same time, the first one placed into the charger will begin charging. When it is fully charged, the second battery will charge. When the LED indicator light turns off, the charger is finished charging the battery in its slot, indicating that the battery is ready for use.

The Dual Battery Charger will recharge a single NiMH Battery Pack or a single Wireless Telephone in two hours. The following precautions should be considered:

The Dual Battery Charger must be placed on a flat, horizontal surface in order to insure proper contact with the Battery Pack contacts.

To ensure proper charging and prevent damage, the Battery Pack or Wireless Telephone should be at room tempera- ture (between 50° and 85° F, 10° and 30° C) when charging.

Do not place the charger where it is subject to extreme temperature varia- tions, such as sunny windows or heat- ing/cooling vents.

Before you use the Wireless Telephone for the first time, the Battery Pack must be charged.
