Battery
Your wireless telephone comes with one nickel-metal hydride rechargeable
battery that provides up to 12 hours of talk time (fully charged).
Low Battery Indications
If the battery runs low while a call is in progress, the handset beeps once every
three seconds.
If the battery is low while the telephone is in Standby Mode:
• Handset beeps every 15 seconds for 3 minutes
• None of the buttons operate
• Handset cannot make or receive calls
• Battery Charge icon indicates the current state of the handset’s battery.
When the icon reduces to one bar, return the handset to the cradle or swap
the battery with a charged one.
It is recommended that you have a spare battery always charging to ensure
against complete battery discharge. See
“Charge the Spare Battery” on page 28
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.
