Dialling mode
The telephone can be operated in new, digital exchanges (TONE/DTMF) as well as
analogue exchanges (PULSE). The dialling mode is controlled via the menu. Refer to
Page 180 for the sequence of menu option selections.
Alarm clock
This function can be used so that the telephone (base station) wakes or alerts you at a

Caller identification (CLIP)
The caller number display (CLIP) and display of date and time are optional
services offered by your telephone network provider. Contact them for any
further information.
If the CLIP function is available for your telephone system (CLIP = C alling L ine I dentifi-
cation P resentation), the number of the caller appears in the display when a call is re-
ceived − as long as callers have agreed to transmission of their phone number.
If you do not take a call received, the information remains in the display for
approx. 20 seconds before the current time and date reappear.
