A100 OPERATING MANUAL
© 2002 Design, 2012 Doc. No. 12-7271-r01 (4/25/12)
SURF MAIN, information includes (Fig. 9, 10):
> Surface Interval time (hr:min) with clock/wave (Surface Mode) icon; if no dive yet, this is time since activation.
> CF icon, if set On.
> DSAT (or Z+) icon, Algorithm selected.
> Dive number with # icon, up to 12 for that operating period (0 if no dive made yet).
> Altitude level graphic, if L2 (to L7), blank if Sea level.
> NX icon, if FO2 is set for Nitrox.
> TLBG, if any after a dive.
> Battery icon, if voltage is low.
• B (< 2 sec) to access ALT 1, then step forward through other Surface selections.
SURF ALT 1 (Last), information includes (Fig. 11):
> Max Depth* with FT (or M) and MAX icons.
> Elapsed Dive Time* (hr:min) with wave/clock icon.
> LAST icon, indicating that data is from the dive previously conducted.
*Dashes if no previous dive
• B (< 2 sec) to access ALT 2* (or Fly/Desat).
• Reverts to Main in 10 seconds if B is not pressed.
SURF ALT 2*, information includes (Fig. 12):
> Current O2% saturation with icon.
> Current FO2 set with FO2 & NX icons.
> PO2 alarm value, fixed at 1.40.
• B (< 2 sec) to access Fly/Desat.
• Reverts to Main in 10 seconds if B is not pressed.
*ALT 2 is not displayed if FO2 was set for AIR.
SURFACE SEQUENCE
After the ALT screens, there is a sequence of selections in which you can -
> view Time to Fly/Desaturate.
> view Plan Depth/Time limits (NDLs).
> view Log data.
> set Gas (FO2).
> set Alarms (Depth, EDT, DTR).
> set Utilities (Units, Algorithm, Conservative Factor).
> view ID (Serial Number, Firmware Revision).
Press/release B repeatedly (< 2 sec each time), to step through the sequence then return to the Surface Main.
While in the sequence, operation will revert to the Surface Main if B is not pressed within a period of 2 minutes.
The sequence cannot be accessed during the first 10 minutes on the surface following a dive, only the ALTs.
FLY/DESAT TIME
FLY Time is a count down timer that begins counting down 10 minutes after surfacing from a dive from 23:50 to 0:00 (hr:min).
DESAT Time, also a count down timer, provides calculated time for tissue desaturation at sea level taking into consideration the
Algorithm used and the Conservation Factor setting.
DESAT Time also begins counting down 10 minutes after surfacing from a dive, counting down from 23:50 (max), usually much
less, to 0:00 (hr:min).
When the DESAT time reaches 0:00, which will generally occur prior to the FLY count down reaching 0:00, it will remain on the
display until the FLY count down reaches 0:00.
> 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.
> When other screens are accessed, the FLY and DESAT countdowns continue in the background.
FLY/DESAT, information includes (Fig. 13):
> Time to Fly countdown (hr:min) with FLY and clock (time) icons, dashes if no dive yet.
> Time to Desaturate countdown (hr:min) with SAT and clock (time) icons, dashes if no dive yet or a Violation dive.
• B (< 2 sec) to access Plan Lead-in.
