Fly Mode; Desat Mode; Norm/Gaug Log Mode - Sherwood Scuba AMPHOS AIR 2.0 Manual

PLAN DEPTH/TIME, information includes (Fig. 59):
> Max Depth allowed for the PO2 Alarm value set with MAX and FT (or M) icons, blank if FO2 is set for Air.
> Plan Depth with FT (or M) icon.
> Dive Time (min) allowed for the Depth displayed with min icon, NDC or OTL up to 199 minutes.
> Tank 1 icon indicating Gas (mix) 1.
> N2, or O2, icon, indicating that Nitrogen or Oxygen is the limiting time factor in control of calculations.
• S (< 2 sec), repeatedly, will step upward through the Planned Depths in increments of 10 FT (3 M).
• M (2 sec), or if no button is pressed within 2 minutes, operation will revert to the Surface Main.

FLY MODE

Time to Fly is a counter that begins counting down 10 minutes after surfacing from a dive from 23:50 to 0:00 (hr:min).
Ten minutes after a dive, operation reverts to Watch Default Time and the Time to Fly countdown continues in the background. Access to the
Fly screen is then gained by first accessing NORM (or GAUG) SURF Main.
NORM SURF Main >> A (< 2 sec), while viewing Plan Lead-in, will access Fly.
GAUG SURF Main >> S (< 2 sec) will access Fly.
TIME TO FLY, information includes (Fig. 60):
> Countdown Time (hr:min).
> Graphic FLY.
• A (< 2 sec) will access Desat Time if in NORM, or revert to Surface Main if in GAUG.
• M (2 sec), or if no button is pressed within 2 minutes, operation will revert to the Surface Main.
• L (press) will activate the Backlight.
DESAT MODE (NORM only)
The Time to Desaturate counter provides calculated time for Tissue Desatuation at sea level taking into consideration the Conservation Factor
setting. It begins counting down 10 minutes after surfacing from a dive, counting down from 23:50 (hr:min) max to 0:00. When the Count-
down reaches 0:00, which will generally occur prior to the Fly countdown reaching 0:00, the Desat screen remains accessible displaying 0:00
until the Fly counter shuts the Dive Computer operations Off 24 hours after a last dive.
> The Desat screen is not displayed after a Violation dive.
> 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.
> Ten minutes after a dive, operation reverts to Watch Default Time and the Desat countdown continues in the background. Access to the
Desat screen is then gained by first accessing NORM SURF Main.
• A (< 2 sec), while viewing Time to Fly while in NORM mode, will access the Desat Time screen.
DESAT TIME, information includes (Fig. 61):
> Graphic SAT.
> Countdown Time (hr:min) with clock icon.
• A (< 2 sec) will revert to NORM Surface Main..
• M (2 sec), or if no button is pressed within 2 minutes, operation will revert to the Surface Main.
• L (press) will activate the Backlight.

NORM/GAUG LOG MODE

Log Mode displays information from the latest 24 NORM and/or GAUG dives sequentially in reverse order (the most recent first).
Log information is retained until overwritten by another dive.
Battery removal will not affect the Log data stored for viewing.
After exceeding 24 dives, data from the most recent dive completed will be recorded in the Log and the oldest dive's data deleted.
Dives will be numbered 1 to 24 starting at #1 each time a new series of dives begins. When a dive period ends, 24 hours after the last dive,
the first dive of the next new period will be #1.
• A (< 2 sec), while viewing Watch Default Time, NORM SURF Main, or GAUG SURF Main, will access Log Mode displaying the most
recent dive's Log Preview screen.
• S (hold) will scroll through the previous dives' Preview screens at 8 per second, from most recent to oldest recorded.
• S (< 2 sec), while viewing a Preview screen, will display that dive's Log Data 1 screen.
> Log screens remain on display until further button action occurs.
• M (2 sec), or if no button is pressed within 2 minutes, operation will revert to the Surface Main.
• L (press) will activate the Backlight.
