Talk.and.Standby.Times
With average use, your handset battery provides approximately 6 hours of talk time and approximately 7 days
of standby time. When your handset is not being used and is left off of the base unit, the battery will gradually
discharge. You can achieve optimum battery life and performance by returning the handset to the base unit after
each use. If the handset is left off of the base unit, the actual talk time duration will be reduced respective to the
amount of time the handset is off of the base unit.
Low.battery.alert
When the battery pack is very low and needs to be charged, the phone is programmed to
eliminate functions in order to save power. If the phone is not in use, LOW BATTERY appears
on the LCD and none of the keys will operate. During a call, LOW BATTERY flashes and
the handset beeps. Complete your conversation as quickly as possible and return the handset to the base unit for
charging.
