Battery installation & charging
After battery installation, the battery may have enough charge to allow for some
calls. For best performance, place the handset(s) in the telephone base or charger(s)
and allow to charge for 16 hours before use.
You can keep the battery charged by returning the handsets to the telephone base
or chargers after each use. When the battery is fully depleted, a recharge takes
about 12 hours. The average talk time on a fully charged battery is about eight hours
depending on environmental conditions, and the standby time is approximately five
days. Actual battery life will depend on usage conditions and age of battery.
3. Plug the battery
securely into the
plug inside the hand-
set battery compart-
ment, matching the
color-coded label.
