SOS Signals
Unlike other UDI-28™ signals, SOS signals are activated across all network channels, and have a longer
range than ordinary communications signals.
In the event of an emergency, you can activate your SOS signal by pressing the red H (Help) button on
your UDI-28™ for several seconds. An SOS signal is sent to all UDI-28™ and boat unit users in the
area.
