Connecting the Charger

Connect the cable from the adapter plug into the base of the charger and then insert the adapter plug into the mains socket.

Charging the Batteries

You can charge and discharge the batteries hundreds of times, but they will eventually be depleted. When the operating time (that is, the call time and standby time) has become noticeably shorter, replace the batteries. When charging batteries, you should adhere to the following guidelines:

Discharge the battery at intervals to achieve long operating times. To discharge the battery, leave the handset on, but do not place it in the handset charger. Do not attempt to discharge the battery using other methods.

Charge the battery for six to seven hours before using your handset for the first time. The maximum performance of the battery is only reached after three to five charging and discharging cycles.

Place your handset in the charger unit regularly in order to reach the optimum battery charge.

-Charging time: 6 to 7 hours from discharged to full capacity.

-Call time: up to 20 hours (fully charged).

-Standby time: up to 200 hours (fully charged).

After you replace the batteries, the charge level icon will not be displayed until an entire charge cycle is complete.

Caution: Only use the batteries as directed. Never use a damaged battery. Heat and cold reduce the performance and the life of the battery. A handset with either a hot or a cold battery can be temporarily out of operation, even if the battery is fully charged. Dispose of used batteries in accordance with your local regulations. Never throw a battery into a fire.

An icon in the handset display shows the charge level of the battery.
