DESAT MODE (NORM only)
The Time to Desaturate counter provides calculated time for Tissue Desatuation at sea level
taking into consideration the Conservation Factor setting. It begins counting down 10
minutes after surfacing from a dive, counting down from 23:50 (hr:min) max to 0:00.
When the Countdown reaches 0:00, which will generally occur prior to the Fly countdown
reaching 0:00, the Desat screen remains in the sequence of accessible NORM screens
displaying 0:00 until the Fly counter shuts the Dive Computer operations Off 24 hours after
a last dive.
> The SAT screen is not displayed after a Violation Dive.
> Desaturation requiring Times greater than 24 hours will display 23: - - .
> In the event that Time to Desaturate still remains at the end of 24 hours, the added
time will be zeroed.
> Two hours after a dive, operation reverts to the Watch Default Time and the Desat
countdown continues in the background.
> Access to the Desat screen is then gained by first accessing
NORM Surface Main.
• S (< 2 sec) while viewing the NORM Surface Main will
access Plan Lead-in, then A 2 times (< 2 sec each time) will
access the Desat screen.
