Getting started

CAUTION

Do not install the charger, handset, and accessories near the following:

water, moisture, sources of heat, or direct sunlight

devices that generate strong magnetic fields, electrical appliances, fluorescent lamps, computers, radios, televisions, and fax or telephone terminals

areas where the handset can be covered or in excessive dust, and areas subject to vibration, shock, or extreme temperature fluctuations

locations with poor ventilation

CAUTION

Use only the plug-in AC adapter and battery type supplied, and use only approved accessories.

Ensure the mains voltage of the adapter matches the local mains voltage.

Do not use AC adapters that are visibly damaged (cracked or broken) and keep the ventilation slits on the AC adapters free from obstruction.

Attention: The handset, if switched off, automatically switches on when placed in the charger.

Charge display

The battery charge status appears on the display screen. When the battery is nearly discharged, the battery symbol flashes and a warning tone sounds. If you are on a call, approximately 3 to 5 minutes of talk time exists before the handset switches off. If you are not on a call and the handset is not in the charging station, the message “Battery empty” appears on the display. You cannot make calls while this message appears.
