OXYGEN ACCUMULATION

If FO2 was set for a numerical value (Nitrox), the O2BG (Fig.

62a) will add segments to represent oxygen accumulation for

that dive, or 24 hour period, whichever amount is greater.

If O2 reaches 100% of the allowed limit (300 OTU), the graphic

O2 will replace NDC. High O2 is described later.

ASCENT RATE INDICATOR (ASC)

The ASC shows how fast you are ascending. When you exceed

the maximum recommended Ascent Rate for the depth you are at

(see chart on page 33), all segments of the ASC will ﬂash (Fig.

63) and the graphic SLO will ﬂash in place of NDC (or GAU)

(Fig. 63a). The ﬂashing will stop and NDC (or GAU) restored

when the audible is silenced or your Ascent Rate is slowed

below the alarm value.

The Ascent Rate alarm is based upon 2 sets of speeds which

change at a reference depth of 60 FT (18 M).

WARNING: At depths greater than 60 FT (18

M), Ascent Rates should not exceed 60 FPM (18

MPM). At depths of 60 FT (18 M) and shallower,

Rates should not exceed 30 FPM (9 MPM).
