Operation Manual

If the theoretical amount of oxygen accumulated equals, or ex-

ceeds, the limit for a single exposure, or the exposure limit for a 24

hour period, Oxygen Dive Time Remaining becomes zero (0:00)

and the O2 Bar Graph will enter the red O2 (Danger) Zone (Fig.

63). The Audible Alarm will sound (unless set OFF) and the UP

Arrow and the full O2 Bar Graph will flash as a warning until the

level of oxygen decreases below the limit.

You must immediately focus on making a safe controlled As-

cent to the surface to prevent further exposure. As your accu-

mulation (dose) decreases during your surface interval, the O2 bar

graph will gradually recede into the yellow (caution) zone and gray

(normal) zone.

WARNING: In the event that you exceed the maxi-

mum per dive allowable oxygen exposure (dose), it

is recommended that you allow a surface interval

of at least 2 hours before reentering the water. If

you exceed the maximum 24 hour period allowable

oxygen exposure (dose), you must allow a surface

interval of at least 24 hours before reentering the

water.

During conditions of High O2, Alternate Displays previously de-

scribed can be accessed using the Advance (Front) button, and the

Backlight can be activated using the Select (Side) button.
