PATENT NOTICE
U.S. Patents have been issued, or applied for, to protect the following design features:
Dive Time Remaining (U.S. Patent no. 4,586,136), Data Sensing and Processing Device (U.S. Patent
no. 4,882,678), and Ascent Rate Indicator (U.S. Patent no. 5,156,055).
DIVE COMPUTER MODEL
The program within the DG02 simulates the absorption of nitrogen into the body by using a mathemati-
cal model. This model is merely a way to apply a limited set of data to a large range of experiences.
The DG02 dive computer model is based upon the latest research and experiments in decompression
theory. Still, using the DG02, just as using the U.S. Navy (or other) No Decompression
Tables, is no guarantee of avoiding decompression sickness, i.e. “the bends.” Every
diver’s physiology is different, and can even vary from day to day. No machine can predict how your
body will react to a particular dive profile.

INTRODUCTION
Welcome to HOLLIS and thank you for choosing the DG02 !
It is extremely important that you read this Operating Manual in sequence and
understand it completely before attempting to use the DG02.
Remember that technology is no substitute for common sense, and a dive computer
only provides the person using it with data, not the knowledge to use it.
CONTROL BUTTON
The Control Button allows you to select display options and
access specific information when you want to see it. It is also
used to enter settings and activate the Backlight.
BARGRAPHS
Tissue Loading Bar Graph (TLBG)
The TLBG (Fig. 1a) represents tissue loading of nitrogen, show-
ing your relative no decompression or decompression status. As
your depth and elapsed dive time increase, segments will add to
the TLBG, and as you ascend to shallower depths, the segments
will begin to recede, indicating that additional no decompres-
sion time is allowed for multilevel diving.
The TLBG represents 12 different nitrogen compartments simulta-
neously and displays the one that is in control of your dive. It is
divided into a green No Decompression (normal) zone, a yellow
Caution zone (also No Decompression), and a red Decompres-
sion (danger) zone.
While you cannot provide a guarantee against the occurrence of
decompression sickness, you may choose your own personal
zone of caution based upon age, physique, excessive weight,
etc.,toreducethestatisticalrisk.

Oxygen Accumulation Bar Graph (O2BG)
The O2BG (Fig. 2a) represents oxygen loading, showing the
maximum of either per dive or 24 hour accumulated oxygen.
As your oxygen exposure (accumulation) increases during the
dive, segments will add to the O2BG, and as loading de-
creases, it will begin to recede, indicating that additional
exposure is allowed for that dive and 24 hour period.
NOTE: Displays associated with oxygen and the
O2BG will only appear if FO2 has been set at a value
other than 'Air' (e.g., a numerical value).
Variable Ascent Rate Indicator (VARI)
The VARI (Fig. 2b) provides a visual representation of ascent
speed (i.e., an ascent speedometer). Green is a 'normal' rate,
yellow a 'caution' rate, and red is 'Too Fast'.
The segments of the VARI represent two sets of speeds which
change at a reference depth of 60 FT (18 M). Refer to the
chart for segment values.
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, ascent
rates should not exceed 30 FPM (9 MPM).
