To access the Time to Fly Countdown -
press the Advance (Front) button
2 times
(while in Surface Mode)
The unit will revert to Surface Mode after 2 minutes, unless the Advance (Front) button is
pressed to access the Desat Time Countdown.
If a violation occurred during the dive a single dash ( - ) will appear instead of the graphic
FLY.
The Time to Fly counter (Fig. 66) is provided to assist you with deciding when enough surface
time has elapsed to fly (or travel to higher elevations). It begins counting down 10 minutes after
surfacing from a dive (after the Transition Period) displaying the graphic
FLY
and a countdown
that begins at 23:50 (hr:min) and counts down to 0:00 (hr:min).
Two hours after the last dive, the Time to Fly and Desaturation countdowns will be displayed al-
ternately for 3 seconds each until they count down to 0:00 or another dive is made. Access to
other modes is gained by pressing Either button to return to Surface Mode.
After a surface interval of 12 hours, you may choose to fly (or
travel to higher elevations), provided that your dive profile(s) did
not enter decompression. If your diving involved decompression
or a repetitive, multi day profile, it is strongly recommended that
you wait a full 24 hours after your last dive to add a greater de-
gree of protection.
As you should be aware from your own training, the longer you
wait to fly (or travel to higher elevations) after diving, the more
you will reduce your exposure to decompression sickness.
