Getting started

Battery installation & charging

After battery installation, the battery may have enough charge to allow for some calls. For best performance, place the handset in the charger or telephone base and allow it to charge for 16 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 12 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.
