> EDT = with OFF, or 0:10 to 3:00 (hr:min), increments of :05. EDT is Elapsed Dive Time.
> TLBG = with 1 to 8 SEG, increments of 1 SEG. SEG means Segments of the bar graph
> DTR = with OFF, or 1 to 0:20 ( :min), increments of :01. DTR is Dive Time Remaining.
> TURN = with OFF, or 1000 to 3000 PSI (or 70 to 205 BAR), increments of 250 PSI (5 BAR). TURN is pressure of TMT 1.
> END = with 300 to 1500 PSI (or 20 to 105 BAR), increments of 100 PSI (5 BAR). END is pressure of the TMT in use.
• A (< 2 sec) - to step forward (down screen) through and highlight Menu selections.
• M (< 2 sec) - to step back (up screen) through Menu selections.
• S (< 2 sec), when a selection is highlighted - to highlight & flash that item’s set point.
• A (< 2 sec) - to toggle or increase the set point.
• A (hold) - to increase the set point at a rate of 8 per second.

SET UTILITIES MENU (NORM), information includes (Fig. 31A):
Selections with their last Set points saved include:

> DEEP STOP = with OFF or ON.
This only applies to No Deco dives
.
> SAFE STOP = with OFF or ON.
This only applies to No Deco dives
.
> ALGORITHM = with DSAT or Z+.
This determines the basis for Ni-O2 calculations
.
> CONSERV = with OFF or ON.
This, Conservative Factor, reduces NDLs based on altitude level
.
> SAMPLING = with 2, 15, 30, or 60 SEC (second).
This is the rate that data is sampoled and recorded for PC download
.
Additional information relating to the effects of the items included are described in associated sections throughout this manual.

cessed from the NORM Menu (see page 16).
> FO2, PO2 alarms set for - Gas 1, 2, 3, 4.
> Alarm values set for - Depth, EDT, DTR, TLBG, Turn Pressure, End Pressure.
> Water Type selected
.
> Deep Stop seting
.
> Safety Stop setting
.
• A (< 2 sec) - to step forward (down 1st column then 2nd) through & highlight selections.
• M (< 2 sec) - to step back (up) through selections.
