FLY/DESAT
The FLY/DESAT screen displays the Time to Fly and the DESAT (desaturation) countdown. The Time to Fly
countdown shall begin counting from 23:50 to 0:00 (hr:min), 10 minutes after surfacing from a dive. The DESAT
counter shall provide calculated time for Tissue Desaturation at sea level taking into consideration the CF (Con-
servative Factor) if it was set on. It shall begin counting down 10 minutes after surfacing from DIVE or FREE dives
counting down from a maximum of 23 to 10 (hr only), then 9:59 to 0:00 (hr:min). When the DESAT countdown
reaches 0:00 (hr:min), which will generally occur prior to the FLY countdown reaching 0:00 (hr:min), it will remain
on the display as 0:00 until the Fly count down reaches 0:00.

ute allowed dive time will not be displayed.
