NORM SURFACE MODE
Upon access to NORM mode, the Surface Main screen will be displayed during which time the unit will enter Dive Mode upon
descent to 5 FT (1.5 M) for 5 seconds.
If 2 minutes elapse with no button action, operation will enter Power Saver Mode turning the screen off until a button is pressed.
The unit will enter Post Dive Surface Mode upon ascent to 2 FT (0.6 M) for 1 second and display the Surface Main with the SURF
icon flashing.
Access to Alternate screens is allowed during the first 10 minutes with access to other surface modes/screens blocked until
10 minutes elapse.
Exception is for Violations.
When the 10 minute post dive surface Interval time has elapsed, access to other Surface modes/screens is allowed.
NORM SURF MAIN, information includes (Fig. 22A/B):
> Surface Interval Time (hr:min, colon flashing), with SURF icon (flashing during the first 10 minutes after surfacing).
> Graphic NORM; or NDC as 3 dashes ( - : - - ) & EDT (hr:min) with icons during the first 10 minutes after surfacing.
> Graphic GAS 1 (start Gas & default 10 minutes after a dive), Gas in use during the first 10 minutes after surfacing.
> Tank 1 Pressure with PSI (or BAR) icon (start TMT & default TMT 10 minutes after a dive), graphic SPG (meaning Submers-
ible Pressure Gauge) if no TMT is in use; TMT in use during first 10 min after surfacing.
> Graphic DIVE with number of that dive (up to 24), 0 if no dive yet (or 2 dashes - - with GTR icon during the first 10 minutes
after surfacing).
> TLBG, if any after a NORM or FREE dive.
> Low Battery icon - yellow (if voltage is at the warning level), or red flashing (if voltage is at the alarm level).
A (2 sec) - to access the Adjust Brightness screen.
A (< 2 sec) - to access NORM SURF ALT 1.
M (2 sec) - to revert to the Home Menu.
M (< 2 sec) - to access the NORM Menu.
S (2 sec) - to access the Compass OP Main.
ADJUST BRIGHTNESS, information includes (Fig. 23):
> xx % (last value saved). Up to 60% max when Low Battery Warning or Alarm.
S (2 sec) - to step back to the SURF MAIN without changing the value.
A (< 2 sec) - to step upward through values of 10% to 100% one at a time in increments of 10%.
M (< 2 sec) - to step down through values one at a time.
S (< 2 sec) - to save the % setting and revert to the SURF MAIN.
NORM SURF ALT 1, information includes (Fig. 24):
> LAST DIVE (screen title).
> xxx FT (or xx.x M) with graphic MAX DEPTH.
> Elapsed Dive Time (hr:min, up to 9:59) with graphic DIVE TIME.
A (< 2 sec) - to access SURF ALT 2.
M (< 2 sec) - to step back to the SURF MAIN.
10 sec with no button action, revert to the SURF MAIN.
NORM SURF ALT 2, information includes (Fig. 25):
> DATE = m.d.y (or d.m.y).
> TIME = hr:min with AM (or PM) if 12 Hour Format.
> TEMP = xx F (or C).
> ELEV = SEA (or EL2 to EL7).
> FLY = hr:min*
> DESAT = hr:min**
> O2 SAT = xx%.
> GAS 1 = AIR; or xx%, x.xx (FO2, PO2 set).
A (< 2 sec) - to revert to SURF MAIN.
M (< 2 sec) - to step back to SURF ALT 1.
10 sec with no button action, revert to SURF MAIN.
*The Time to Fly counter will begin counting down from 23:50 to 0:00 (hr:min) 10 minutes after surfacing from any dive.
**The Time to Desaturate counter provides calculated time for Tissue Desatuation at sea level taking into consideration the
Conservation Factor setting. It will begin counting down 10 minutes after surfacing from a NORM or FREE dive, counting
down from a maximum of 23:50 to 0:00 (hr:min).
Desaturation requiring times greater than 24 hours will display the graphic > 24:00. In the event that Time to Desaturate
still remains at the end of 24 hours, the unit will turn Off and any Ni-O2 calculations will clear.
