BATTERIES
Battery Life
Battery life depends on how far the handset is from the base, and other
environmental conditions.
NOTE: For optimum battery performance, charge your handset on the
base every night.
Operation: Approximate Battery Life:
IN USE Near base unit 10 hours
(phone on) Away from base unit 10 hours
NOT IN USE Ringer on 15 days
Ringer off 30 days
Charge the Handset Battery Pack
This battery should remain charged up to 15 days with the Ringer on and
up to 30 days with the Ringer off. A fully charged battery provides an
average talk time of about 10 hours.
The battery pack needs charging when:
• A new battery is installed in the handset.
• The phone beeps four times when you press
P.
• The battery status symbol on the screen is only partly displayed.
• The phone does not respond when you press
P.
Place the handset in the base either in the face-down or face-up position so
the CHARGING light turns on. The battery pack is typically fully charged in
six hours. For best results, the initial charge should be 12 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 six hours of
charging, the battery should be replaced.
