In addition to customized regular spoken altitude and speed announcements in each phase of a skydive as well as optional pre- and post-jump briefs,
SonoAlti 4V also contains 100 pre-recorded notifications (e.g. "Breakoff" or "Pull") that can be utilized at any altitude. These notifications will override any regular altitude/speed announcements when they are included in a user preset. Users may create their own notifications as well, as long as the sound files are in the same format (mono 16-bit 44.1 kHz PCM); see the
manual for instructions.
The sounds are categorized below according to the phase of the skydive in which they are available.
