Safety Stop Main; Surfacing - Aqua Lung i550 Owner's Manual

SAFETY STOP MAIN

If triggered, the Safety Stop will activate upon ascent to within 1.5 m (5 ft) deeper than the Safety Stop depth on
a No Decompression dive. The stop time will then countdown to 0 min. While Safety Stop Main is displayed, you
may access up to 3 ALT displays by pressing the ADV button repeatedly. They are similar to the No Decompres-
sion Main, Dive ALT 1, and Dive ALT 2 displays, respectively. See Safety Stop in the Dive Features chapter for
further details.
NOTE: The i550 does not penalize for a missed Safety Stop.

SURFACING

Upon ascending to 0.9 m (3 ft) the i550 transitions to Dive Surface mode. For the first 10 minutes after a dive the
i550 will continue to display the maximum depth and elapsed dive time. Once the surface time reaches 10 min-
utes the i550 will display the standard Dive Surface screen.
NOTE: The i550 requires a 10 minute surface interval to record a subsequent dive as a separate dive in
the Log. Otherwise, the dives will be combined and recorded as a single dive in the i550 memory.
