Operation Manual

Variable Ascent Rate Indicator (VARI)

The Variable Ascent Rate Indicator (Fig. 3a) provides a visual rep-

resentation of ascent speed (i.e., an ascent speedometer). Gray is a

'normal' rate, yellow a 'caution' rate, and red is 'Too Fast'. The seg-

ments of the VARI represent two sets of speeds which change at a

reference depth of 60 feet (18 meters). Refer to the chart for seg-

ment values.

WARNING: At depths greater than 60 feet (18 m),

ascent rates should not exceed 60 fpm (18 mpm).

At depths of 60 feet (18 m) and shallower, ascent

rates should not exceed 30 fpm (9 mpm).

INFORMATIONAL DISPLAYS

Depth Displays

During a dive, the Current Depth display (Fig. 3b), indicates

Depths from 0 to 330 feet (99.9 meters) in increments of 1 foot (.1

meter). The Depth range is extended to 399 feet (120 meters)

when it is set to operate in Digital Gauge Mode.

By pressing the button, the Maximum Depth reached during that

dive will be displayed (Fig. 3c).

During a Decompression Dive, the required Ceiling Stop Depth is

displayed in the Max Depth position.
