Getting started

Battery installation & charging

After battery installation, the battery may have enough charge to allow 

you to make a short call. For best performance, place the handset in the 

charger or telephone base and allow it to charge for 6 hours before use. 
You  can  keep  the  battery  charged  by  returning  the  handset  to  the 

charger or the telephone base after each use. When the battery is fully 

depleted, a recharge takes about 2 hours. The average talk time on a 

fully charged battery is about eight hours depending on environmental 

conditions, and the standby time when idle is approximately five days.
