If an individual call acknowledgement is received, a call tone is activated that is equal to the
call tone used for receiving a call request of the same type.
Calls that are received as distress calls or calls with category distress or urgency will always
adopt 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 a call is received initiating an alarm sound, the alarm sound may be muted by pressing the
button in order to be able to finish current radiotelephony call. This procedure will not
affect the actual call accept procedure.
