Operation Manual

To access the Pre Dive Planning Sequence

(while in the Surface mode) -

• Press the Front (Advance) button 1 time

• Press and release the Side (Select) button to advance through

the Depths/Times, one screen at a time; and then return to

Surface Mode.

• The unit will revert to Surface Mode after 2 minutes if no

button is pressed.

• With each depth displayed by the Pre Dive Planning Se-

quence, you will see either predicted no decompression limits

(NDLs) based upon your previous dive profiles (if calculated

to be nitrogen controlled), or predicted oxygen tolerance

limits (OTLs) based upon either a single dive exposure or your

24 hour accumulation of oxygen (if calculated to be oxygen

controlled).

• The Maximum Depth allowed for the PO2 Alarm value set

and FO2 set point will also be displayed.

• Depths greater than the Maximum Depth that can be

achieved for a PO2 of 1.60 ATA will not be displayed.

• If the Tissue Loading Bar Graph is displayed (Fig. 52a), that

next dive is calculated to be controlled by nitrogen loading.

• If the O2BG and O2 symbol are displayed (Fig. 53a), it is

calculated to be controlled by oxygen loading.
