Operation Manual

Atmos Pro/Aeris 300G

The Fly countdown starts at 23:50 (hr:min) and counts down to 0:00 (hr:min).

The Desaturation counter, lower screen (Fig. 43), provides calculated time for

tissue desaturation at sea level. The countdown starts at 9:59 (hours:minutes)

maximum and counts down to 0:00. If the time is calculated to be greater

than 9:59, the display will indicate 9:+ (Fig. 44) until it decreases to 9:59.

Two hours after the last dive, the Time to Fly and Desaturation countdowns

will be displayed continuously. Access to other modes is gained by depressing

the Select (Right) 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 degree 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.

More About Flying After Diving and DAN's guidelines is presented in the Ref-

erence section.
