Ringer / Vibration alarm
In addition to or instead of the ringer, the built-in vibration
alarm can silently signal incoming calls.
Time/ Alarm
In the idle state the display shows the current time. After initial
commissioning or after a battery change, the display is set at
00:00. The time is updated when you dial your next external
call.
The handset has a programmable alarm function.
Internal and External Telephone Numbers
The internal and external telephone numbers on which you can
be reached are assigned when the communications system
(Forum 500) is set up.
Multiple Connections
Two calls can be made to your handset simultaneously. Any fur-
ther callers will hear a busy signal.
VF Post-Dialling/Signalling
In the call state, your telephone is automatically set to VF sig-
nalling ("voice-frequency signalling"). You can use VF signalling
to query an answerphone or voicebox.
Display of Call Charges and Call Duration
If your provider transmits call charge information, you can see
the current charge in the display during or after a direct-dialled
external call.
