Fly/Desat, information includes (Fig. 29/30):
> Time to Fly (hr:min), 0:00 if no dive yet, dashes ( - - : - - ) during first 10 min on surface, with graphic FLY.
> Time to Desat (hr:min), 0:00 if no dive yet, dashes ( - - : - - ) during first 10 min on surface, with graphic DESAT.
> Time (clock) icon.
• S (< 2 sec) - to revert to Menu.
• L (press) - to activate Backlight.
NORM PLAN MODE
No Deco Dive Times (NDLs) in NORM Plan Mode are based on the Algorithm selected (DSAT or Z+) and only on the FO2 set for
Gas 1. FO2 set for Gas 2 and 3 are not used.
NORM Menu >> Plan Lead-in >> PDPS
Plan Lead-in, information includes (Fig. 31A/B):
> Graphic PLAN.
> Graphic FO2_1 (Gas 1).
> Graphic Air or numeric % value (21 to 100), indicating the FO2 set for Gas 1.
> Graphic PO2 with PO2 Alarm value set (1.20 to 1.60), if Nitrox, blank if Air.
> Nx icon, if Nitrox.
• S (< 2 sec) - to access PDPS.
• L (press) - to activate Backlight.
PDPS (Pre Dive Planning Sequence)
The PDPS displays Depths and allowable No Deco Dive Times. It will sequence through Depths from 30 to 190 FT (9 to 57 M),
or the Max Depth that will allow theoretical No Deco Dive Time of at least 1 minute based upon the previous dive profiles in a
series of repetitive dives and taking into account descent and ascent rates of 60 FPM (18 MPM).
When the Conservative Factor is set On, No Deco Dive times are reduced to the values of the next 3000 foot (915 meter) higher
Altitude. Refer to tables in back.
PDPS, information includes (Fig. 32A/B):
> Max Depth with MAX and FT (or M) icons, if Nitrox, blank if set for Air.
> Plan Depth value with graphic FT (or M).
> Graphic NDC (or OTR) with Dive Time allowed (hr:min) with Time (clock) icon, no OTR if Air.
> Graphic PO2 with PO2 Alarm value set for Gas 1 (1.20 to 1.60), if Nitrox, blank if set for Air.
> Nx icon, if Nitrox.
• A (hold) to scroll upward through screens at a rate of 8 per second increasing planned Depth from 30 to 190 FT (9 to 57 M)
in increments of 10 FT (3 M).
• A (< 2 sec) - to step upward through screens one at a time.
• M (< 2 sec) - to step back through screens one at a time.
• S (< 2 sec) - to revert to the Plan Lead-in screen.
• L (press) - to activate Backlight.
NORM/GAUG LOG MODE
Information from the latest 24 NORM and/or GAUG dives is stored for viewing. After exceeding 24 dives, the most recent dive
is stored while the oldest is deleted.
> Dives are numbered from 1 to 24 starting each time NORM (or GAUG) Dive Mode is activated. After the post dive 24 hour
period has elapsed, the first dive of the next operation period is #1.
> 10 minutes after surfacing from dives, the Log screens for that dive as well as all other dives stored can be viewed.
> In the event that a dive’s elapsed time (EDT) exceeds 9:59 (hr:min), the data at the 9:59 interval is recorded in the Log upon
surfacing of the unit.
NORM Menu >> Log Preview >> Log Data 1 >> Log Data 2
Log Preview, information includes (Fig. 33):
> Log Mode (book) icon.
> Graphic NO-D (or DECO or GAUG or VIOL).
> Graphic DIVE and dive number (1 to 24, 0 if no dive yet).
> Time dive began (hr:min) with Time (clock) icon and A (or P), and the graphic ALT if Alternate Time.
> Date, the dive was conducted.
> Nx icon, if Nitrox.
• A (hold) - to scroll upward through Preview screens at a rate of 8 per second.
• A (< 2 sec) - to step upward through screens one at a time.
• M (< 2 sec) - to step back through screens one at a time.
• S (< 2 sec) - to access that dive's Log Data 1 screen.
• L (press) - to activate Backlight.
