Battery charging
Once you have installed the battery, the screen indicates the battery status 
(see table below). If necessary, place the handset in the telephone base or 
charger to charge the battery. For best performance, keep the handset in 
the telephone base or charger when not in use. The battery is fully charged 
after 16 hours of continuous charging. See the table on the Technical 
specifications page in the user’s manual for battery operating times.
If the screen shows Low battery, you need to charge the battery without 
interruption for at least 30 minutes to give the handset enough charge to use 
the telephone for a short time. The following table summarizes the battery 
charge indicators and actions to take.
