5.4.7 User Sounds
The
2N LTE
intercoms
provide standard signalling of operational statuses by tone sequences;
refer to the Signalling of Operational Statuses subsection.
If you find the standard sound
signalling inconvenient, modify the sounds for the following statuses:
Ringing before answering call
Ringback tone
Call busy tone
Call hang-up
Invalid input
Invalid user position
Switch activation
You can either completely mute the above-mentioned sounds
, replace
them with one of the ten
predefined sounds, or simply record a sound file of your own into the intercom. The sound file
must have the WAV format and use PCM encoding with 8/16 kHz sampling frequency and 8/16-
bit sample resolution, and the file size may not exceed 256 kB.
