Battery installation & charging
After installing the battery, you may be able to make or receive short calls. For
best performance, place the handset in charger to charge for 16 hours before
use.
You can keep the battery charged by returning the handset to charger after use.
When the battery is fully depleted, a recharge takes about 12 hours. The average
talk time on a fully charged battery is about five hours, and the standby time is
approximately six days. Actual battery life depends on usage conditions and age
of battery.

indicated. Be sure to
securely insert the
plug, making sure
