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 Variable Ascent Rate Indicator (U.S. Patent no. 5,156,055). User Setable Display (U.S. Patent no. 5,845,235) is
owned by Suunto Oy (Finland).
DECOMPRESSION MODEL
The program within the Veo 100 simulates the absorption of nitrogen into the body by using a mathematical model. This
model is merely a way to apply a limited set of data to a large range of experiences. The Veo 100 dive computer
model is based upon the latest research and experiments in decompression theory. Still, using the Veo 100, 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.

FEATURES and DISPLAYS
WARNING: Prior to diving with the Veo 100, you must
also read and understand the Oceanic Dive Computer
Safety and Reference Manual which provides Important Warnings and Safety Recommendations as well
as general product information.

INTRODUCTION
Welcome to Oceanic and thank you for choosing the Veo 100
Personal Dive Computer (PDC)!
It is extremely important that you read this Operating Manual in
sequence and understand it completely before attempting to use
the Veo 100.
It is equally important that you read the Oceanic Dive Computer
Safety and Reference Manual (Doc. No. 12-2262) provided with
your Veo 100. It contains information that you must become
familiar with prior to diving with your Veo 100.
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.
The Veo 100 has numerous features that are described throughout this manual.
CONTROL BUTTON
The Control Button (Fig. 1) allows you to select display options
and access specific information when you want to see it.
Fig. 1 - Control Button

BAR GRAPHS
Tissue Loading Bar Graph (TLBG)
The Tissue Loading Bar Graph (Fig. 2a) represents tissue loading
of nitrogen, showing your relative no decompression or decompression status.
The Tissue Loading Bar Graph monitors 12 different nitrogen
compartments simultaneously and displays the one that is in
control of your dive.
As your depth and elapsed dive time increase, segments will add
to the Graph, and as you ascend to shallower depths, the Bar
Graph will begin to recede, indicating that additional no decompression time is allowed for multilevel diving.
It is divided into a green No Decompression (normal) zone, a
yellow Caution zone (also No Decompression), and a red
Decompression (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., to reduce the statistical risk.

Variable Ascent Rate Indicator (VARI)
The Variable Ascent Rate Indicator (Fig. 3a) 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 feet (18 meters). Refer
to the chart for segment values.
WARNING: At depths greater than 60 feet (18 meters),
ascent rates should not exceed 60 fpm (18 mpm). At
depths of 60 feet (18 meters) and shallower, ascent
rates should not exceed 30 fpm (9 mpm).
ALPHA / NUMERIC DISPLAYS
Depth Displays
During a dive, the Current Depth display (Fig. 3b), indicates
Depths from 0 to 330 feet (99 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.
During a Decompression Dive, the required Ceiling Stop
Depth is displayed in the Max Depth position.

Time Displays
Time displays are shown in hour:minute format (i.e., 1:16
represents 1 hour and 16 minutes, not 116 minutes!). The colon
that separates hours and minutes blinks once per second when
the display is indicating real time (e.g., Elapsed Dive Time), and
is solid (non-blinking) when times are calculated projections (e.g.,
Time to Fly).
The Main Time display has the largest digits of the display (Fig.
4a) A second time display (Fig. 4b) is located above it. Both
displays are identified by clock icons.
Date Display
Date is displayed only to identify dive data while it is viewed in
the Log Mode. When Units of Measure are set for 'Imperial', the
Month appears to the left of Day. When set for Metric, the
Month appears to the right of Day.
Temperature Display
Ambient Temperature is displayed in Surface Mode (Fig. 4c)
and Log Mode, and can be viewed as an Alternate Display when
the button is pressed while in a dive mode (Fig. 5a). If the
Temperature exceeds a value of '99', 2 dashes ( - - ) will be
displayed until temperature decreases to '99'.

POWER SUPPLY
The Veo 100 utilizes 1 - 3 volt CR2450 Lithium Battery which
should provide from 100 dive hours of operation, if you conduct
1 - one hour dive each time the unit is activated, to as many as
300 dive hours of operation, if you conduct 3 or more one dives
each time the unit is activated.
Low Battery Condition
• Voltage level is checked upon activation and every 10
minutes during operation.
• When 75 % of the Rated Power has been consumed, a
Battery icon will appear on the Surface Mode display (Fig.
6a) flashing once per second as a warning that the Battery is
to be replaced prior to conducting any further dives.
• Upon decreasing to a voltage level that will no longer sustain
proper operation, the icon will flash 5 times followed by
shutdown of the unit.
• If a Low Battery Condition exists when the unit is manually
activated (by pressing the button), the icon will appear
flashing for 5 seconds followed by shutdown of the unit.
• If the button is not pressed to activate the unit prior to a dive
(e.g., the unit activated automatically by immersion in water),
and a Low Battery Condition exists, the Battery icon will
appear flashing as a warning upon descent to 5 feet (1.5
meters). No other information will be displayed and the unit
will not enter Dive Mode.

• If the unit did not display a Low Battery Condition prior to
entering the Dive Mode, and a Low Battery Condition occurs
during the dive, there will be sufficient Battery power to
maintain unit operation for the remainder of that dive.
• The Battery icon will not appear if a Low Battery Condition
occurs during a dive. It will appear after the dive, upon entry
into Surface Mode.
• When the Battery is removed, settings and nitrogen calculations for repetitive dives will be retained, if a new battery
can be inserted within 8 seconds. Otherwise the calculations
will reset to zero and settings must be reset.
NOTE: Each display represents unique pieces of
information.
It is imperative that you understand the formats,
ranges, and values of the information represented to
avoid any possible misunderstanding that could result
in error.
The Informational Displays are described in detail as
the various operating modes they appear in are presented throughout this manual.

The Veo 100 is configured with contacts that will automatically activate the unit
when the space between the contacts is bridged by a conductive material
(immersed in water).
The contacts are the pins of the Data Port and stem of the Push Button.
It is important that the Data Port and Button be kept clean and free of any
contamination or debris that could cause the unit to activate unnecessarily
resulting in premature depletion of battery power.
It is also important that they be kept clean to ensure that the unit will activate and
enter dive mode upon immersion and descent.
The Data Port and Button can be cleaned with fresh water and a soft bristle
brush.
WARNING: The Wet Activation feature will not function unless it is
Set ON (a user setting) and the contacts are bridged without interference. If the contacts remain dry during a descent and an attempt is
made to activate it at depth, it will come On briefly then shut Off

SETUP AND ACTIVATION
WARNING: Prior to diving with the Veo 100, you must
also read and understand the Oceanic Dive Computer
Safety and Reference Manual which provides Important Warnings and Safety Recommendations as well
as general product information.
16
ACTIVATION
To Activate the Veo 100 - press and release the Button.
• Upon manual activation, the unit will enter Diagnostic Mode
(Fig. 7), displaying all segments of the LCD as 8's, followed
by dashes (- -), then a countdown from 9 to 0.
• Diagnostic Mode checks the display and battery voltage to
ensure that everything is within tolerance and functioning
properly.
• It will also check the ambient barometric pressure, and
calibrate its present depth as zero. At elevations of 2,000
feet (610 meters) or higher, it will adjust its depth readings
and no decompression limits for that elevation.
WARNING: If it is manually activated at elevations
higher than 14,000 feet (4,270 meters), it will perform a
diagnostic check followed by immediate shutdown.
Identification of the Computer Module
To view a screen that displays the unit's serial number and
firmware revision level, hold the button depressed as the Diagnostic countdown reaches 00. The Serial Number screen appears
(Fig. 8). Upon releasing the button, the unit shuts Off. Press the
button again to reactivate the unit.
Fig. 7 - Diagnostic Mode
Fig. 8 - Serial Number
17
Backup Activation (only if Water Activation is set ON)
As a backup, the unit will also automatically activate by water
contact. This is accomplished by bridging the gap between
contacts located on the Button and housing.
If no dive is made within 2 hours after activation, the unit will
deactivate. If the wet contacts are still wet, it will reactivate.
SURFACE SEQUENCE
While on the surface, the unit will automatically scroll through a
Sequence of displays including -
• Surface Mode
• Fly Mode
• DeSat Mode
• Plan Mode
As the Surface Sequence is scrolling, you can use the button to
access Log Mode and Set Mode.
SURFACE MODE
Surface Mode information includes (Fig. 9) -
• Dive Number if the module is dry (0 if no dive made yet), or
the graphic H2O if the module is wet (Fig. 10)
• Temperature (and icon).
• Time of Day (with icon).
• Surface Interval (with flashing colon) and Surface Time icon.

Pre Dive Planning Sequence (PDPS)
The PDPS (Fig. 11) provides a sequence of theoretical dive times
available for depths ranging from 30 feet (9 meters) to 190 feet
(57 meters) in 10 foot (3 meter) increments.
No decompression times (limits), or NDLs, are only displayed for
depths where there is at least 3 minutes of theoretical dive time
available at the depth, taking into account a descent rate of 60
feet (18 meters) per minute.
The PDPS should be reviewed prior to every dive to help you plan
your dive as required to avoid exceeding no decompression
limits. For repetitive dives, it indicates adjusted dive times that
are available for the next dive, based on residual nitrogen
following the last dive and surface interval.
WARNING: The available dive times provided by the
PDPS are only predictions. Depending on cylinder
size and air consumption rate you may have less time
available than indicated because of those or other
limitations.
SET MODE
After gaining access to Set Mode, settings can be made in
sequence one after the other, or you can access a specific item
that you want to set, bypassing others.
