NORM Mode >> for Air and Nitrox SCUBA activity with 1 or 2 Gases.
GAUG Mode >> for SCUBA activity with no nitrogen/oxygen calculations.
FREE Mode >> for breath hold diving activity with calculations based on 21% O2.
If no previous dive has been taken within the past 24 hours, NORM is the default upon
activation. Others accessed using the Surface Menu.
At any time while operating in Surface Modes, operation will enter the Dive Mode se-
lected upon descent to 5 FT (1.5 M) for 5 seconds.
• When Wet Activation is set Off, Dive Mode will not be activated unless the unit is
turned On while on the surface.
• When Wet Activation is set On, immersion in water will activate the unit which will
then enter the Dive Mode selected upon descent.
Operation will revert from Dive Mode to Surface Mode upon ascent to 2 FT (0.6 M) for
1 second. During the first 10 minutes after a NORM/GAUG dive or 1 minute after a
FREE dive, the Dive Main screen will remain on displaying Max Depth and Elapsed Dive
together with Surface Interval Time with the colon ashing.
• A descent during the rst 10 minutes after surfacing from a NORM or GAUG dive, or
the first 1 minute after surfacing from a FREE dive, is a continuation of that dive.
• After the 10 minute (or 1 minute) interval has elapsed, the normal Surface Main will
be displayed. A descent is then considered a new dive.
