Operation Manual

With each depth display you will see either 'predicted' no decompression limits

based upon your previous dive profiles (if calculated to be nitrogen controlled),

or 'predicted' oxygen tolerance limits based upon either a single dive OTU or

your 24 hour accumulation of oxygen (if calculated to be oxygen controlled).

The DataPlus will then return to the Surface mode, continuing the sequence for

the first 12 hours after surfacing. The no decompression limits for a “clean”

dive (no dives in the previous 24 hours) are those listed in Figure 36.

Information displayed (Fig. 36) includes Depth in increments of 10FT (3M), No

Decompression Limit (Dive Time) available at that depth (which includes

descent time at a rate of 120 ft/min), the PDPS mode icon, and the loaded TLBG

(if nitrogen controlled) or the loaded O2 bar graph and 'O2' symbol (if O2 con-

trolled). No Decompression times are only displayed for depths where there are

at least 3 minutes of dive time available at the depth, taking into account a

descent rate of 120 feet (36 meters) per minute. Depths greater than the maxi-

mum depth that can be achieved with a PO2 of 1.60 BAR will not be displayed.

WARNING: The DataPlus must be manually activated and be in

the Surface Mode or PDPS Mode prior to start of a dive. The

unit will not activate automatically by immersion in water. Also,

FO2 must be set prior to commencing each nitrox dive.
