Battery Life

Battery life depends on how far the handset is from the base, and other environmental conditions.

NOTE: For optimum performance, charge your handset on the base every night.

Charge the Handset Battery Pack

This battery should remain charged for up to five days. A fully charged battery provides an average talk time of about six to eight hours.

The battery pack needs charging when:

– The battery icon (

) flashes,

A warning tone sounds, or

The screen displays LOW BATTERY when idle.

Place the handset in the base so the CHARGING light goes on. The battery pack is typically charged in eight hours. For best results, the initial charge should be twelve hours.

You can keep the battery fully charged by returning the handset to the base after each use.

If you repeatedly get a Low Battery indicator, even after eight hours of charging, the battery should be replaced.

CAUTION: To reduce the risk of fire or injury to persons or damage to the telephone, read and follow these instructions carefully:

Use only Replacement Battery 2401, SKU# 91077.

Do not dispose of the battery in a fire. The cell might explode. Check with local codes for special disposal instructions.
