6. Handling calls
00 8811 17, 08/18 (Rev. 6.0) 27
You can also determine the category of a call by listening:
The more urgent the call, the faster the sequence of the sounds.
If there are several calls, you will only hear the most urgent call.
Call category Sound sequence
Call 1 second sound / 10 seconds pause
Emergency call 1 second sound / 1 second pause
Alarm 0.3 seconds sound / 0.3 seconds pause
NOTE! The audible call indication is particularly important, if
you do not have the main window on your display. Calls can
only be heard. They are not displayed.
NOTE! While there is a speech connection there is no acoustic
call signalling.
