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 "Technical data", page 119. • The descriptions of the display symbols can be found in the chapter "Display sym- 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 backlighting, and activated vibra alarms and Bluetooth mode.
