VIOLATION AND GAUGE MODES

The 500AI enters Violation Modes when it is unable to predict an ascent proce-

dure.

If the 500AI enters a Permanent Violation Mode, it will not display informa-

tion relating to nitrogen or oxygen loading for the remainder of that dive or for

subsequent dives conducted during the 24 hour period after surfacing. It will

operate in a Gauge Mode displaying only Depth and Elapsed Time.

NOTE: Violation Modes and Gauge Mode are described on

pages 60 - 65.

ASCENDING TO THE SURFACE

While ascending to shallower depths, the segments that have filled up the Ni-

trogen Bar Graph will begin to recede (Fig. 45), offering a graphic representa-

tion of your multilevel diving capability.

A safety stop made between 15-20 feet (5-6.5 meters) is strongly rec-

ommended as a standard procedure before completing your ascent.
