Installation and first-time operation
Charging the battery
The batteries are supplied uncharged. To charge the batteries, place the phone in the
charging unit.
It is only after the battery has been charged for the first time that your phone is ready
for use, that calls can be answered and that you can make calls from the phone.
Notes:
• It takes several charging cycles before a new battery reaches full capacity.
• The technical data can be found in the chapter
• The descriptions of the display symbols can be found in the chapter
bols", page 20.
• Poor radio links (sizeable distance to the system's radio station) will reduce the
phone's standby and talk times. The standby and talk times are also reduced by
high loudspeaker or ring tone volumes, frequently used keypad and display back-
lighting, and activated vibra alarms and Bluetooth mode.
