Battery

Your wireless telephone comes with one nickel-metal hydride rechargeable
battery that provides up to 10 hours of talk time (fully charged).

Low Battery Indications

If the battery runs low while a call is in progress, the Battery Low icon appears in
the handset display, and the handset beeps once every three seconds.
If the battery is low while the telephone is in Standby Mode:
• Battery Low icon appears in the handset display
• Handset beeps every 15 seconds for 3 minutes
• None of the buttons operate
• Handset cannot make or receive calls
It is recommended that you have a spare battery always charging to ensure
against complete battery discharge. See
for more information. To restore the battery capacity, return the handset to the
charger unit for charging or replace the handset battery with a charged one. The
battery can remain in the charger unit for over one month.
