PATENT NOTICE
U.S. Patents have been issued, or applied for, to protect the following design features:
Data Sensing and Processing Device (U.S. Patent no. 4,882,678). Set TLBG Alarm and other patents pending. User
Setable Display (U.S. Patent no. 5,845,235) is owned by Suunto Oy (Finland).
DECOMPRESSION MODEL
The programs within the VEO simulate 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 dive computer model is
based upon the latest research and experiments in decompression theory. Still, using the VEO, 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.

There are 9 Menus that include the -
• NORM Menu
• GAUG Menu
• FREE Menu
• Set F Menu
• Set A Menu
• Set M Menu
• Set T Menu
• Set U Menu
• Set FA Menu
Each Menu has a Start (First) selection and a Stop (Last) selection. Upon entering a Menu, movement through it starts at the
Start (First) selection, then continues in a rolling manner showing
one selection at a time.
• The sample at the left shows how a menu would look if all
of the selections would be displayed on one screen.
Page 11
Menu button action >>
A (< 2 sec) - to access and step forward through menu selections
A (hold) - to scroll forward through menu selections
S (< 2 sec) - to access or save selections
Pressing A (< 2 sec) while viewing the last selection in the menu will revert to the first selection (such as Surface Main).
At any time while on the surface, depressing the A and S buttons simultaneously for 2
seconds will revert operation to the Surface Main. Exception is during the first 10 minutes
after surfacing from NORM/GAUG dive, or first minute after surfacing from a FREE dive.
SMARTGLO® Backlight
The VEO is configured with a sensor capable of measuring the intensity of ambient light.
The Backlight will only come on when light level is low.
To activate the SmartGlo Backlight >> press the S button.
• If ambient light level is low, the Backlight will activate and illuminate the display
for button depression time* plus the Duration time set (0, 5, or 10 seconds), for a
maximum of 20 seconds.
(*The Backlight will turn Off if S is depressed for more than 10 seconds.)
• Press S again to activate as desired.
Extensive use of the Backlight reduces estimated Battery life. Also,
the Backlight does not operate during a Low Battery Condition or
when the VEO is connected to a PC.

AUDIBLE ALARM
While operating in NORM or GAUG Mode, the Audible will emit 1 beep per second for
10 seconds when alarms strike, unless it is set Off. During that time, the Audible can be
acknowledged and silenced by pressing the S button (less than 2 seconds).
An LED Warning Light, on the lower end of the housing, is synchronized with the Audible
and flashes as the Audible sounds. It will turn Off when the Alarm is silenced. The Audible and LED will not be active if the Audible is Set OFF (a group A setting).
FREE Dive Mode has its own set of Alarms which emit 3 short beeps either 1 or 3 times
which cannot be acknowledged or set Off.
Situations that will activate the NORM/GAUG 10 second Alarm include ** Items activate only in NORM mode.
• Descent deeper than the Depth Alarm Set Point selected.
• Dive Time Remaining at the Set Point selected**.
• Elapsed Dive Time at the Set Point selected.
• PO2 at the Set Point selected**.
• High O2 of 300 OTU (100%)**.
• TLBG at the Set Point selected**.
• Ascent Rate exceeds 60 FPM (18 MPM) when deeper than 60 FT (18 M), or 30 FPM
(9 MPM) at 60 FT (18 M) and shallower.
• Entry into Decompression Mode (Deco)**.
• Conditional Violation (above a required Deco Stop Depth for less than 5 minutes)**.
• Delayed Violation (above a required Deco Stop Depth for more than 5 minutes)**.
• Delayed Violation (a Deco Stop Depth greater than 60 FT/18 M is required)**.
12
Page 13
• Delayed Violation (Max Operating Depth of 330 FT/100 M is exceeded in NORM
or FREE mode, or 399 FT/120 M in GAUG mode).
A single short beep (which cannot be disabled) sounds when -
• After 10 minutes on the surface after the Violation dive.
3 short beeps (which cannot be disabled) sound when -
• Ascent Rate is 51 to 60 FPM (15.1 to 18 MPM) when deeper than 60 FT (18 M), or
26 to 30 FPM (7.5 to 9 MPM) at 60 FT (18 M) and shallower.
• FREE Dive Elapsed Dive Time Alarm (3 beeps every 30 seconds if set On).
During the following NORM Dive situations, the 10 second continuous tone will be followed by a 5 second steady beep that will not turn off when acknowledged -
• Ascent above a Deco Stop for more than 5 minutes.
• Deco requires a Stop Depth deeper than 60 FT/18 M or deeper.
• On the Surface during a Conditional Violation.

PC INTERFACE
Interface with a PC, to allow uploading settings and downloading data, is accomplished
by connecting the VEO to a PC USB Port using the special VEO USB Interface Cable.
The software program together with the USB Driver required is on the Oceanlog CD, and
can be downloaded from the OceanicWorldwide web site. The program's HELP** serves
as the user manual which can be printed for personal use.
** Prior to attempting to Download data from your VEO or Upload Settings to it, review
the HELP section of the Oceanlog program. Recommended is to print those sections
of HELP that you consider appropriate for your Interface activities.
The Settings Upload portion of the Oceanlog program can be used to set/change Set
A (Alarms), Set U (Utilities), Set T (Time, Date), and Set FA (Free Alarms) using the same
Interface System. FO2 related items must be set using the control buttons.
Information available for retrieval (download) from the VEO to the PC Download portion
of the program includes dive data such as dive number, surface interval time, maximum
depth, elapsed dive time, no deco status, start date/time, lowest temperature under water,
sampling rate, dive profile, and Set Points.
The Oceanlog program also allows upgrade of select versions of the VEO's firmware
(operating system software) after which the VEO resets all operating data. Since the
upgrades require reset of the VEO, they are blocked during 24 hours after dives.
• Refer to page 88 for more details relating to Oceanlog and PC Interface.

OPERATING MODES
NORM Mode >> for Air and Nitrox SCUBA activity
GAUG Mode >> for SCUBA activity
FREE Mode >> for breath hold diving activity with Depth/Time indication
If no previous dive has been taken within the past 24 hours, NORM is the default upon
activation. Others accessed using the Surface Menu.
At any time while operating in Surface Modes, operation will enter the Dive Mode selected upon descent to 5 FT (1.5 M) for 5 seconds.
• When Wet Activation is set Off, Dive Mode will not be activated unless the unit is
turned On while on the surface.
• When Wet Activation is set On, immersion in water will activate the unit which will
then enter the Dive Mode selected upon descent.
Operation will revert from Dive Mode to Surface Mode upon ascent to 4 FT (1.2 M) for
1 second. During the first 10 minutes after a NORM/GAUG dive or 1 minute after a
FREE dive, the Dive Main screen will remain on displaying Max Depth and Elapsed Dive
together with Surface Interval Time with the colon flashing.
• A descent during the first 10 minutes after surfacing from a NORM or GAUG dive, or
the first 1 minute after surfacing from a FREE dive, is a continuation of that dive.
• After the 10 minute (or 1 minute) interval has elapsed, the normal Surface Main will
be displayed. A descent is then considered a new dive.

ACTIVATION
To activate the VEO, press/release any button.
• The unit will enter Diagnostic Mode displaying all segments
of the LCD as 8's, followed by dashes (- -), then a
countdown from 9 to 0. It checks the display and voltage
to ensure that everything is within tolerance.
• After manual activation, it will also check the ambient
barometric pressure, and calibrate its present depth as 0.
At elevations of 3,001 feet (916 meters) or higher, it will
adjust depth calibration for the higher altitude.
The VEO is configured with contacts located on the stems of the
buttons and pins of the PC Data Port that will automatically activate the unit and cause it to enter dive mode when the contacts
become wet and it senses depth of 5 FT (1.5 M).
After activation and diagnostics, the VEO will enter NORM
Surface Mode displaying the Main screen and allow access to
the NORM Surface Menu.

FLY/SAT TIME
Time to Fly is a countdown timer that begins counting down from 23:50 to 0:00 (hr:min)
10 minutes after surfacing from a dive (NORM, GAUG, or FREE).
Time to Dsaturation, also a countdown timer, provides calculated time for tissue desaturation at sea level taking into consideration the Conservation Factor setting. It also begins
counting down 10 minutes after surfacing from a dive (NORM or FREE), counting down
from 23 to 10 (hr only), then 9:59 to 0:00 (hr:min).
When the SAT countdown reaches 0:00, which will generally occur prior to the FLY countdown reaching 0:00, it will remain on the display until the FLY countdown reaches 0:00.

The VEO is configured with a feature that allows data to be cleared, including nitrogen
and oxygen calculations and Log entries. This is intended for facilities using the VEO for
rental or training activities, not for general use by individual divers.
WARNING: Reset after a dive and subsequent use for a repetitive
dive conducted by the same diver could result in serious injury or
death.
Upon access, a factory assigned code number is displayed with the graphics CLR and id,
all solid (Fig. 45).

BAR GRAPHS
The VEO features 2 specific bar graphs.
> The one on the left represents nitrogen loading. It is
referred to as the TLBG (Tissue Loading Bar Graph).
> The one on the right represents ascent rate. It is referred to
as the VARI (Variable Ascent Rate Indicator).
TLBG (NORM only)
The TLBG represents your relative No Deco (Fig. 46a) or Deco
status (Fig. 47a). The first 4 segments represent No Deco status
and the fifth indicates a Deco condition.
As your Depth and Elapsed Dive Time increase segments add.
As you ascend segments recede, indicating that additional no
deco time is available.
The VEO monitors 12 different nitrogen compartments simultaneously and the TLBG displays the one that is in control of your
dive at any given time.
Page 47
VARI (NORM and GAUG)
The VARI (Fig. 48a) provides a visual representation of ascent
speed (i.e., an ascent speedometer).
The segments represent two sets of speeds which change at a
reference depth of 60 FT (18 M). Refer to the chart.
When ascent is too fast, all segments will be displayed flashing
(Fig. 49) until ascent is slowed.
WARNING: When deeper 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).
The VEO is configured with 2 algorithms which allows you to choose which set of NDLs
(No Deco Limits) will be used for nitrogen/oxygen calculations and displays relating to
Plan and DTR (Dive Time Remaining).
You can select to use either the DSAT or the PZ+. The selection will lock in for 24 hours
after the last dive.
DSAT has been the standard used by Oceanic in all of its dive computers until this
time. It features NDLs that are based on exposures and test data which also formed
validation for the PADI RDP. It imposes restrictions for repetitive Deco dives, considered more risky.
PZ+ (Pelagic Z+) performance is based on Buhlmann ZHL-16c. It features NDLs that
are considerably more conservative especially at shallower depths.
To create even greater margins of safety with respect to decompression, a Conservative
Factor as well as No Deco Deep and Safety Stops can be included for No Deco dives.
CONSERVATIVE FACTOR (CF)
When the CF is set On, the NDLs which are based on the algorithm selected and used for
Ni/O2 calculations and displays relating to Plan and DTR, will be reduced to the values
available at the altitude level that is 3,000 feet (915 meters) higher. Refer to the charts in
the back of this manual for times.

Page 49
DEEP STOP (DS), No Deco only
When the DS selection is set On, it will trigger during NORM No Deco dives when you
descend to 80 FT (24 M), then calculate (and continually update) a Stop Depth equal to
1/2 the Max Depth.
While 10 FT (3 M) deeper than the calculated DS, you will be able to access a DS Preview screen that will display the current DS Stop Depth/Time.
Upon initial ascent to within 10 FT (3 M) below the calculated Stop Depth, a DS screen
displaying a Stop Depth at 1/2 the Max Depth will appear with a Countdown Timer
beginning at 2:00 (min:sec) and counting down to 0:00.
> If you descend 10 FT (3 M) below, or ascend 10 FT (3 M) above, the calculated Stop
Depth for 10 seconds during the countdown, the No Deco Main will replace the
DS Main display and the DS feature will be disabled for the remainder of that dive.
There is no Penalty if the DS is ignored.
> In the event that you enter Deco, exceed 190 FT (57 M), or a High O2 condition (=>
80%) occurs, the DS will be disabled for the remainder of that dive.
> The DS is disabled during a High PO2 Alarm condition (=> Set Point).
SAFETY STOP (SS), No Deco only
If set On:
Upon ascent to within 5 FT (1.5 M) deeper than the SS Depth set for 1 second on a No
Deco dive in which Depth exceeded 30 FT (9 M) for 1 second, a beep will sound and a
SS at the Depth set will appear on the Main display with a countdown beginning at the SS
Time set and counting down to 0:00 (min:sec).
49
Page 50
• If the SS was set for OFF or Timer, the display will not appear.
• In the event that you descend 10 FT (3 M) deeper than the Stop Depth for 10 seconds
during the countdown, or the countdown reaches 0:00, the No Deco Main screen
will replace the SS Main screen which will reappear upon ascent to within 5 FT (1.5
M) deeper than the Safety Stop Depth set for 1 second.
• In the event that you enter Deco during the dive, complete the Deco obligation, then
descend below 30 FT (9 M); the SS Main will appear again upon ascent to within 5
FT (1.5 M) deeper than the SS Depth set for 1 second.
• If you ascend 2 FT (0.6 M) shallower than the SS Depth for 10 seconds prior to
completing it, the SS will be canceled for the remainder of that dive.
• There is no Penalty if you surface prior to completing the SS or ignore it.
If set for Timer On:
Upon ascending to 20 FT (6 M) for 1 second on a No Deco dive in which Depth exceeded 30 FT (9 M) for 1 second, 1 beep will sound and a Run Timer will appear (if set On)
displaying 0:00 (min:sec) until started.
• If the SS was set for Off or On, the Timer display is not to appear.
• If you descend deeper than 30 FT (9 M) for 10 seconds, the No Deco Main will
replace the Timer screen which will reappear upon ascent to 20 FT (6 M) for 1
second.
• If you ascend above 10 FT (3 M) for 10 seconds, or enter Deco, or a High O2 alarm
condition occurs (100%), while the SS Timer is active, the SS Timer will be disabled
for the remainder of that dive.
50
Page 51
DTR (DIVE TIME REMAINING)
The VEO constantly monitors No Deco status and O2 Accumulation, and will display whichever Time is the least amount available as DTR on the No Deco Dive Main screen. The Time being
displayed will be identified by the NDC or O2 icon.
NDC (No Deco DTR)
NDC is the maximum amount of time that you can stay at your
present Depth before entering Deco. It is calculated based on
the amount of nitrogen absorbed by hypothetical tissue compartments.
The rates each of these compartments absorb and release
nitrogen is mathematically modeled and compared against a
maximum allowable nitrogen level.
Whichever one is closest to this maximum level is the controlling
compartment for that Depth. Its resulting value (NDC) will be
displayed as DTR (Fig. 50a). It will also be displayed graphically as the TLBG (Fig. 50b).
As you ascend, the TLBG segments will recede as control shifts
to slower compartments. This is a feature of the decompression
model that is the basis for multilevel diving, one of the most
important advantages that Oceanic dive computers offer.

To fulfill your decompression obligation, you should make a safe
controlled Ascent to a depth slightly deeper than, or equal to,
the required Stop Depth indicated and decompress for the Stop
Time indicated.
The amount of decompression credit time that you receive is
dependent on Depth, with slightly less credit given the deeper
you are below the Stop Depth indicated.
You should stay slightly deeper than the required Stop Depth
indicated until the next shallower Stop Depth appears. Then,
you can slowly ascend to, but not shallower than that indicated
Stop Depth.

INFORMATION PERTAINING TO FREE DIVE MODE
• Although breathing apparatus is not utilized for Free Dive activities, nitrogen tissue loading
remains a factor. Nitrogen loading is calculated based upon a fixed FO2 of Air.
• Since a user has the option of alternating between SCUBA and Free Dive activities within a 24
hour period, nitrogen calculations and the displayed value of No Deco Dive Time Remaining
(NDC time) are carried over from one operating mode to the other, which permits the user to
maintain awareness of nitrogen absorption and offgasing status.
• The mathematical models currently used in the VEO are based on no decompression/
decompression multilevel repetitive dive schedules.
• These algorithms do not take into account the physiological changes associated with the high
pressures that competitive type Free diving can expose a diver to.
WARNINGS
• Ensure that you know which Operating Mode is selected (NORM, GAUG, or FREE)
prior to commencing any dive.
• Conducting Free dives within a 24 hour period after conducting SCUBA dives,
combined with the effects of multiple rapid Free Dive ascents, increases your risk
of decompression sickness. Such activities may result in accelerated entry into
decompression which could cause serious injury or death.
• Combining competitive type Free dive activities that involve multiple descents/
ascents with activities utilizing SCUBA during the same 24 hour period is not
recommended. Presently, there is no data relating to such activities.
• It is highly recommended that anyone planning to become involved in
competitive type Free dive activities obtain proper instruction and training from
a recognized Free Diving trainer. It is imperative that the physiological affects
be understood and the diver is physically prepared.

High Nitrogen Alarms
When nitrogen increases to the caution level (4 TLBG segments),
the audible will sound during which time the TLBG segments will
flash on the Main (Fig. 103).
In the event that nitrogen continues to increase and reaches the
Deco level, the audible will sound during which time; all 5 TLBG
segments, the Up Arrow icon, and the graphic VIO (in place of
Temperature), will flash, and NDC will display 0.
When the audible is silent, the TLBG and NDC digits are removed. The graphic VIO and Up Arrow icon flash until on the
surface (Fig. 104), then the Up Arrow is removed.
The graphic VIO flashes until 1 minute elapses on the surface
(Fig. 105), then it alternates with FRE and operation reverts to
Violation Gauge Mode for 24 hours.

The Settings Upload portion of the program can be used to set/
change the Set A group (Alarms), Set U group (Utilities), and Set
T group (Time/Date) using the same Interface System. The FO2
and Mode settings must be entered using the button controls.
Information available for retrieval* (downLoad) from the VEO to
the PC Download portion of the program includes items such as
dive number, surface interval time, depth, dive time, start date
a
and time, lowest temperature, sampling rate, Set Points, TLBG,
and VARI.
*
FREE Dive information is only available using the PC Interface system.
The VEO checks for the presence of an interface device connection to the Data Port once every second* while in Surface mode.
*
Checks are not made if the Wet Activation contacts are wet.

CARE AND CLEANING
Protect your VEO from shock, excessive temperatures, exposure
to chemicals, and tampering. Protect the lens against scratches
with a Instrument Lens Protector. Small scratches will naturally
disappear underwater.
• Soak and rinse the VEO in fresh water at the end of each
day of diving, and check to ensure that the areas around
the Low Pressure (Depth) Sensor (Fig. 108a), PC Interface
Data Port (Fig. 108b), and buttons are free of debris or
obstructions.
• To dissolve salt crystals, use lukewarm water or a slightly
acidic bath (50% white vinegar/50% fresh water). After
removal from the bath, place the VEO under gently running
fresh water and towel dry before storing.
• Transport your VEO cool, dry, and protected.
b

MODULE REMOVAL FROM BOOT
If the module is in a console, bend the rubber console boot back to expose the edge of
the module. If the boot is flexible enough to permit, you may bend it back far enough to
scoop the module out with your finger. Otherwise, it may be necessary to insert a blunt
screwdriver until the tip rests just underneath the module.
DO NOT pry the module from the console! Slowly increase the pressure under the module
by releasing the tension on the rubber boot. The module will slide up the screwdriver and
exit the console.
If the module is in a wrist boot, it will be necessary to peel the lips of the boot downward
off the module while applying pressure from underneath, working it out slowly.
When the battery is removed, settings and calculations for repetitive dives
are retained in the unit's memory while a new battery is installed.
BATTERY REPLACEMENT
The battery compartment should only be opened in a dry and clean environment with
extreme care taken to prevent the entrance of moisture or dust.
To prevent formation of moisture in the battery compartment, it is recommended that the
battery be changed in an environment equivalent to the local outdoor temperature and
humidity (e.g., do not change the battery in an air conditioned environment, then take it
outside during a hot sunny day).

Battery Cover Removal
• Turn the module over to expose the Battery Cover.
• While applying steady inward pressure on the center of
the Battery Cover, rotate the Retaining Ring 10 degrees
clockwise by pressing against the upper tab of the Ring
with a small blade screwdriver (Fig. 109).
• Lift the Ring up and away from the Housing, or turn the
Module over to allow the Ring to drop out into your hand.
• Remove the Battery Cover.
Battery Removal
• Remove the Retaining Bar located across the lower portion
of the Battery (Fig. 110a).
• Remove the Cover O-ring. DO NOT use tools.

ALTITUDE SENSING AND ADJUSTMENT
Altitude (i.e., ambient pressure) is measured upon activation and every 15 minutes until a
dive is made.
> Measurements are only taken when the unit is dry.
> Two readings are taken, the second reading 5 seconds after the first. The readings
must be within 1 foot (30 cm) of each other to record that ambient pressure as the
current Altitude.
> No adjustments are made during any time that the Wet Contacts are bridged.
> When diving in high altitude waters from 3,001 to 14,000 feet (916 to 4,270
meters), the VEO automatically adjusts to these conditions providing corrected Depth,
and reduced No Deco and O2 Times at intervals of 1,000 feet (305 meters).
> When the Conservative Factor is set On, NDLs are calculated based upon the next
higher 3,000 foot (915 meter) Altitude.
> At Sea Level, calculations are based upon an Altitude of 6,000 feet.
> All adjustments for Altitudes greater than 11,000 feet (3,355 meters) are then made
to allowable dive times for 14,000 feet (4,270 meters).
> The VEO will not function as a Dive Computer above 14,000 feet (4,270 meters).
