If an individual call acknowledgement is received, an alarm tone is activated that is equal to
the alarm tone used for receiving a call request of the same type.
Calls that are not received as distress calls or calls with category distress or urgency will
always engage the prescribed alarm sound. For any other DSC calls the call sound on
reception can be enabled/disabled from a Setup menu (4.3.2).
If you receive a call with an alarm sound, you will always be able to mute the alarm by
pressing the button
to be able to finish current radiotelephony call. This procedure
will not affect the actual call accept procedure.
