THE BATTERY PACK
Charging the Handset Battery Pack
The handset of your VT 1421 cordless telephone is powered by a rechargeable battery pack. It charges automatically whenever the handset is in the base. You should charge the battery pack for 16 hours when you first receive your phone. You’ll know the battery pack needs recharging when:
•The phone emits a warning tone when you press the PHONE key.
•The low battery message is displayed on the handset:
•The handset seems completely dead; the display is clear and the handset does not beep or light when you press the keys.
To Charge the Battery Pack
To charge the battery pack, place the handset in the base unit. The CHARGING indicator will light to show the handset is seated properly and the battery pack is charging. It is recommended that the battery pack be for at least 16 hours initially, and 8 hours for maintenance charging. You can use your telephone before that with diminished capacity, but it is best to charge the battery pack fully. It will take several recharge cycles to maximize the charge capacity of your battery pack. The maximum battery life between charges is 7 hours of continuous talk time or 7 days if standby time.
Alternatively, if you have purchased a spare battery pack and it has been charging in the base unit, simply exchange the drained handset battery pack with the fully charged battery pack from the base charger. Place the drained handset battery pack in the base charger.
The base spare battery charger does not charge a battery pack as quickly as the handset battery charger. A full charge requires 24 hours when using the base unit spare battery charger.
It is impossible to overcharge the battery. The battery pack can be recharged many times, but if you get a low battery message even after 16 hours of charging in the base cradle (or 24 hours in the base spare battery charger), the battery pack(s) should be replaced.

A Word about Rechargeable Batteries
Your battery pack recharges whenever the handset is returned to the base unit cradle. You may return the handset to the cradle whenever it is not in use.
