Dive Computer Mode

Dive Computer mode is automatically entered when the

computer enters the water. It begins performing its dive

calculations once you descend below 5 feet (1.5 meters).

Caution: Prior to diving, always check to ensure that the

O/C or C/C modes, FO2 and FHe settings are correct and

that the computer is not in default mode.

While in diving mode, the computer calculates and displays

information about your dive and prompts you with safety/deco

stop information and warnings if needed.

While underwater, there are two screens you can toggle between

and you can switch to different gas mixes when needed.

Primary Underwater Screen

When you enter the water, the primary screen shows your depth,

remaining no-decompression time limit, dive time, max depth,

PO2 for selected mix, mix number, O2 and HE percentages for

gas selected, and the OLI and PGT bar graphs.

(1) Depth: This is the current depth.

(2) Maximum depth: This is the maximum depth that has been

reached during the dive.

(3) PO2: This is the partial pressure of O2 at your current depth.

It is based on the FO2 settings for the mix selected.

(4) O2 (OLI) bar graph: This is the oxygen limit index (OLI)

that calculates the cumulative effect of your exposure to elevated
