INTRODUCTION
Welcome to Oceanic and thank you for choosing the Veo
100Nx !
It is extremely important that you read this Operating Manual in
sequence and understand it completely before attempting to use
the Veo 100Nx.
It is equally important that you read the Oceanic Dive Computer
Safety and Reference Manual (Doc. No. 12-2262) provided
with your Veo 100Nx. It contains information that you must
become familiar with prior to diving with your Veo 100Nx.
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

BAR GRAPHS
Tissue Loading Bar Graph (TLBG)
The Tissue Loading Bar Graph (Fig. 1a) represents tissue loading
of nitrogen, showing your relative no decompression or decompression status. 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.
The Tissue Loading Bar Graph monitors 12 different nitrogen
compartments simultaneously and displays the one that is in
control of your dive. It is divided into a No Decompression
(normal) zone, a Caution zone (also No Decompression), and a
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.
a
NOTE: Displays associated with oxygen and the O2
Bar Graph will only appear if FO2 has been set at a
value other than 'Air' (e.g., a numerical value).
Fig. 1 - TLBG

Oxygen Accumulation Bar Graph (O2BG)
b
The O2 Bar Graph (Fig. 2a) represents oxygen loading, showing the maximum of either per dive accumulated oxygen, or 24
hour period accumulated oxygen.
a
As your oxygen exposure (accumulation) increases during the
dive, segments will add to the Bar Graph, and as loading
decreases, it will begin to recede, indicating that additional
Fig. 2 - O2BG and VARI
exposure is allowed for that dive and 24 hour period.
Variable Ascent Rate Indicator (VARI)
The Variable Ascent Rate Indicator (Fig. 2b) provides a visual
representation of ascent speed (i.e., an ascent speedometer).

POWER SUPPLY
The Veo 100Nx utilizes one (1) type CR 2450 Lithium 3 volt cell
that should provide 300 hours of continuous, or 50 activation
periods, of operation.
If you conduct 1 dive each time the unit is activated, you should
obtain approximately 50 dives.
a
If you conduct 3 dives each time the unit is activated, you should
obtain approximately 150 dives.
Fig. 7 - BATTERY ICON
Battery Indicator
A Battery Indicator provides an indication of battery condition.
When power is sufficient for normal unit operation, the Indicator
will be displayed during Surface Mode (Fig. 7a). The Indicator
will not be displayed during Dive Mode(s).
Low Battery Condition
Voltage level is checked upon activation and every (1) minute
during operation on the surface.
 When 75 % of the Rated Power has been consumed, the
lower bar of the Battery Indicator (only segment) will be
displayed, and the outline of the Indicator will flash once per
second (Fig. 8) as a warning that the Battery is to be replaced prior to conducting any further dives.
Fig. 8 - LOW BATTERY
13
 Upon decreasing to a voltage level that will no longer sustain
proper operation, the Indicator will flash 5 times followed by
shutdown of the unit.
 If a Low Battery Condition exists when the unit is activated
(by pressing the button), the graphic bAT and the Battery
Indicator 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,
and a Low Battery Condition exists, the Battery Indicator will
appear flashing as a warning upon descent to 5 FT (1.5 M).
No other information will be displayed.
 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 Indicator will then appear after the dive upon entry

FO2 MODE
After Activation, the Veo 100Nx will operate as an AIR computer without displaying information associated with oxygen
calculations, unless it is set for a percentage of oxygen (FO2)
other than AIR (a numerical value between 21 and 50 %).
When set for an FO2 value of AIR (Fig. 9), the Veo 100Nx
will perform calculations the same as if FO2 were set for 21%
oxygen, internally accounting for oxygen loading for any subsequent Nitrox dives. However, oxygen related displays, warn-

ings, and the O2 Bar Graph will not appear on the display for
that dive, or subsequent dives, unless FO2 is set for a numerical
value (21 to 50).
Once a dive is made with the unit set as a nitrox computer (FO2
set for a numerical value), it cannot be programmed to operate
as an AIR computer until 24 hours after the last dive. AIR will
not be displayed as an option in the FO2 Mode. However, you
can set FO2 for 21% for use with AIR.
When FO2 is set at a value of 21% (Fig. 10), the unit will
remain set at 21% for subsequent nitrox dives until FO2 is set to
a higher value, or until it automatically turns Off and is reactivated.
Setting FO2 is described on Page 21.

FO2 50% DEFAULT
If the FO2 Default is set to ON (Fig. 11) and FO2 is set to
a value greater than 21%, the FO2 set point value will automatically revert to 50% 10 minutes after that dive. The Maximum
Depth that can be achieved with a PO2 of 1.60 ATA will also
be displayed.
Fig. 11 - FO2 Default ON
 FO2 must therefore be reset for each repetitive nitrox dive,
or the value will automatically Default to 50(%) and the dives
will be calculated based on 50% O2 (50% nitrogen) for
oxygen calculations and 21% O2 (79% nitrogen) for nitrogen calculations.
If the Default is set to OFF (Fig. 12), the FO2 value for
repetitive dives remains the same as previously set until the Set
Point is manually changed.

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 or oxygen exposure limits.
For repetitive dives, the PDPS indicates adjusted dive times that
are available for the next dive, based on residual nitrogen or
oxygen accumulation (whichever is in control) following the last
dive and surface interval. It appears after the SAT screen in the
scrolling Surface Sequence (SURF > FLY > SAT > PDPS).
WARNING: The available dive times provided are
only predictions, depending on cylinder size and air
consumption rate, you may have less time available
than indicated because of those and other factors.
 With each Depth displayed by the PDPS, you will see either
predicted no decompression limits (NDLs) based upon your
previous dive profiles (if calculated to be nitrogen controlled), or predicted oxygen tolerance limits (OTLs) based
upon either a single dive exposure or your 24 hour accumulation of oxygen (if calculated to be oxygen controlled).
 The Maximum Depth allowed for a PO2 level of 1.60 (ATA)
for the FO2 setting will also be displayed.
 Depths greater than the Maximum Depth that can be
achieved with a PO2 of 1.60 ATA will not be displayed.
 If the Tissue Loading Bar Graph is displayed (Fig. 26), that
Fig. 26 - NITROGEN IN
CONTROL
next dive is calculated to be controlled by nitrogen loading.
 If the O2BG and O2 symbol are displayed (Fig. 27), it is
calculated to be controlled by oxygen loading.
NOTE: The Veo 100Nx will store O2 accumulation
calculations for up to 10 dives conducted during a 24
hour period. If the maximum limit for oxygen loading
has been exceeded for that day (24 hour period), all
of the segments of the O2BG will be displayed flashing.
Depth/Time values will not appear until the O2BG
recedes into the normal zone (i.e., your daily O2
dosage decreases an amount equal to the amount
accumulated during the latest dive completed).

amount is greater.
VARI (VARIABLE ASCENT RATE INDICATOR) (Fig. 28c)
The Variable Ascent Rate Indicator (VARI) shows how fast you
are ascending. When you exceed the maximum recommended
ascent rate for the depth you are at (see page 10), the TOO
FAST icon will appear flashing and all segments of the VARI will
flash (Fig. 29). The flashing will stop and the TOO FAST icon
will be removed from the display when your Ascent Rate is
slowed below the alarm value.

CONTROL OF DISPLAYS
During No Decompression conditions, various displays of
information (up to 4) are available. Each provides Depth, Dive
Time Remaining, and additional information. The intent of this
feature is to allow the diver to select which information is on
display at any given time during the dive. The screens can be
changed from one display to another as often as desired by
pressing and releasing the button momentarily (< 2 seconds).
During conditions in which cautionary type information is displayed (e.g., Decompression, High PO2, High O2, etc.), there is
a Main Display of important information relevant to the specific
condition. Other screens of information can be accessed, which

The amount of decompression Credit Time that you receive is
dependent on Depth, with slightly less Credit given the deeper
you are. You should stay slightly deeper (Fig. 36d page 36)
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 ceiling Stop Depth.

Conditional Violation Mode
If you ascend shallower (Fig. 41a) than the Required Decompression Ceiling Stop Depth displayed (Fig. 41b), the Down Arrow,
Deco Bar, and Total Ascent Time will flash until you descend
below the Required Stop Depth. Current Depth and applicable
bar graphs will be displayed.

minutes of Penalty Time will be added to Required Stop Time.
The added Penalty (decompression) Time will have to be
'worked off' first, before obtaining 'off gassing' credit. Once the
Penalty Time is 'worked off', and 'off gassing' Credit begins,
required Deco Stop Depths and Time will decrease toward zero,
then the Veo 100Nx will revert to the No Deco Dive Mode.

a greater Stop Depth.
If your Decompression obligation requires a Ceiling Stop Depth
'between' 60 FT (18 M) and 70 FT (21 M), the full TLBG will
flash. Total Ascent Time will still be displayed.
You must ascend to just deeper than, and stay as close as
possible to, 60 FT (18 M) without causing the Total Ascent Time
display to flash.
When the Required Stop Depth indicates 50 FT (15 M), etc., you
can ascend to those depths and continue decompressing.

Delayed Violation Mode #3 (Fig. 44)
If you descend deeper than 330 FT (99.9 M), the loaded TLBG
segments will flash, and the Current Depth and Max Depth
displays will only indicate 3 dashes ( - - - ).
Upon ascending above 330 FT (99.9 M), the Current Depth
display will be restored, however, Max Depth will only display 3
dashes for the remainder of that dive. The Log for that dive will
display 3 dashes as the Max Depth achieved.
Immediate Violation and Violation Gauge Mode
Fig. 44 - DELAYED
VIOLATION #3
During a Dive, if a ceiling much greater than 60 FT (18 M) is
required, an Immediate Violation Mode will be entered. This
situation would be preceded by entering Delayed Violation
Mode #2.
The Veo 100Nx would then operate with limited functions in
Violation Gauge Mode during the remainder of that dive and for
24 hours after surfacing. Violation Gauge Mode turns the Veo
100Nx into a digital instrument without any decompression or
oxygen monitoring functions. Only Current Depth, Max Depth,
Elapsed Dive Time, and the Variable Ascent Rate Indicator will
be displayed (Fig. 45). The TLBG and O2BG will both flash as
a warning of this condition.
Fig. 45 - VIOLATION GAUGE
MODE
41
The Veo 100Nx will also enter an Immediate Violation Mode 5
minutes after reaching the surface from a dive in which a Delayed Violation occurred.
On the surface, Violation Gauge Mode displays the Dive Number, Temperature, Time of Day, Surface Interval, and TLBG and
O2BG flashing (Fig. 46). It does not provide the FO2, PDPS, or
Time to Fly and Desaturate features.
The countdown timer that appears when you try to access Time
to Fly does not represent 'Time to Fly'. It is only provided to
inform you of the time remaining before normal Veo 100Nx
operation can resume with full features and functions.
NOTE: This condition is a Permanent Violation, and
in the event that a dive is made during the 24 hour
period, a full 24 hour surface interval must then be
served before all functions are restored.

HIGH OXYGEN ACCUMULATION
The O2 Bar Graph displays either oxygen accumulated
during that nitrox dive, or during the repetitive nitrox dives
you conduct during that 24 hour period, whichever of the two
is greater at that time.
The O2 Bar Graph offers you a convenient way to consistently
monitor how close you are coming to the limits of oxygen
exposure. Use it as a visual reference to place a wider
margin of protection between you and the Limits.
If the theoretical amount of oxygen accumulated equals, or
exceeds, the limit for a single exposure, or the exposure limit
for a 24 hour period, Oxygen Dive Time Remaining becomes
zero (0:00) and the O2 Bar Graph will enter the O2 (Danger)
Zone (Fig. 49). The UP Arrow and the full O2 Bar Graph will
flash as a warning until the level of oxygen decreases below
the limit.

POST DIVE SURFACE MODE
When you ascend to 2 FT (0.6 M) or shallower, the Veo 100Nx
will enter Surface Mode and begin counting Surface Interval.
TRANSITION PERIOD
The first 10 minutes is, in affect, a Transition Period during which
time the following information is displayed (Fig. 50):

 Temperature (ambient)
 Time of Day and icon
 Battery icon
 Surface Interval time (colon flashing) and icon (flashing)
 Tissue Loading Bar Graph
 O2 Bar Graph (if set for Nitrox)
During the Transition Period, Log Mode can be accessed. No
other modes (e.g., PDPS, Fly, Desat, Set) are accessible.
To view the Log for that dive (Fig. 51), press/release the button
(less than 2 seconds).
Log Data will not be stored in the unit's memory until the 10
minute Transition Period on the surface is completed.
Fig. 51 - LOG MODE
(during Transition Period)
46
If you descend during the 10 minute Transition Period, time
underwater will be considered a continuation of that dive. The
time at the surface (if less than 10 minutes) will not be added as
Elapsed Dive Time.
AFTER THE TRANSITION PERIOD (THE FIRST 2 HOURS)
Once 10 minutes have elapsed, the Surface Mode icon and
Surface Interval time display colon stop flashing indicating that
the Dive and Transition Period are completed, and a subsequent
descent will be considered a new dive.
Fig. 52 - TIME TO FLY
For the remainder of the first 2 hours after surfacing, information
will continue to be displayed as the Surface Sequence, scrolling
through the Surface Mode > Fly > Sat > Plan screens. You will
also have full access to Log and Set modes.
Time to Fly/Desaturate
The Time to Fly and Desat Timers begin counting down 10
minutes after surfacing from a dive (after the Transition Period).
The FLY countdown (Fig. 52) always begins at 23:50 (hr:min)
and the Desat countdown (Fig. 53) at 23:50 (maximum).
If a Violation occurred during the dive a single dash ( - ) will
appear instead of the letters FLY. DeSat time will not be displayed.
Fig. 53 - DESAT TIME
47
The Time to Fly counter is provided to assist you with deciding
when enough surface time has elapsed to fly (or travel to higher
elevations).
 After a Surface Interval of 12 hours, you may choose to fly
(or travel to higher elevations), provided that your dive
profile(s) did not enter decompression.
 If your diving involved decompression or a repetitive multi
day profile, it is strongly recommended that you wait a full
24 hours after your last dive to add a greater degree of
protection.
Pre Dive Planning Sequence (PDPS)
After a dive, the PDPS provides 'adjusted' No Decompression
Limits (Fig. 54) based on residual nitrogen calculated to be
remaining from that dive and previous dives in the same series.
Fig. 54 - ADJUSTED NDLs

Log Mode
The Veo 100Nx will store up to 12 dives in its Log for viewing. Once the Log is full (12
dives), each subsequent dive will then overwrite the oldest dive stored in the Log. It is
therefore suggested that you transfer the Log's data to your log book at the end of each
day of diving.
Log data will not be lost when the battery is removed/replaced, however, factory service
and calibration will delete the data.
The first dive conducted each time the unit is Activated will be #1, therefore there may be
multiple #1 dives in the Log.
Each dive has 3 Log screens - Dive Identifier (Preview), Dive Data, and O2 Data (if a
Nitrox dive). Dives are displayed in a reverse sequence that starts with the dive most
recently recorded, back to the oldest one stored. The most recent dive will always be the
first shown in the sequence.

UNEXPECTED LOSS OF DISPLAYED INFORMATION
If your Veo 100Nx stops working for any reason, it is important that you have anticipated
this possibility and are prepared for it. This is an important reason for not push-
ing the No Decompression and Oxygen Accumulation Limits, and a critical
reason to avoid entering Decompression.

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.
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).
NOTE: If the old Battery can be removed and the new one inserted within 8
seconds, nitrogen and oxygen calculations and settings, will be retained for
repetitive dives.
58
Battery Hatch Removal
 Locate the Battery Compartment on the back of the Module.
 While applying steady inward pressure on the center of the
Battery Hatch, rotate the Hatch Retaining Ring 10 degrees
clockwise using a flat blade screwdriver (Fig. 64) or a
Battery Hatch Tool.
 Lift the Hatch 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 Hatch.
Fig. 64 - RING REMOVAL
Battery Removal
 Remove the Retaining Bar located across the lower portion of

WARNING: If damage or corrosion is found, return
your Veo 100Nx to an Authorized Oceanic Dealer, and
DO NOT attempt to use it until it has received factory
prescribed service.
Battery Installation
 Slide a new 3 volt type CR2450 Lithium Battery, negative (-)
side down into the Battery Cavity. Slide it in from the right
side and ensure that it slides under the contact clip on the left
rim of the cavity (Fig. 66).
 Orient the Retaining Bar across the lower portion of the
Battery and carefully push it down into position (Fig. 67).
Battery Hatch and Hatch Retaining Ring Installation
 Replace the Hatch O-ring with a new one which must be a
genuine Oceanic part that can be purchased from an Authorized Oceanic Dealer. Use of any other O-ring will void the
warranty.

evenly and completely down into place with your same
thumb.
 Maintain the Battery Hatch securely in place and, using
your other hand, slide the Retaining Ring down off your
thumb and into position around the Battery Compartment.
 The tabs on the Retaining Ring fit down into the two slots
located at the 2 and 8 o'clock positions.
 Using your fingers, turn the Ring counter clockwise 5
degrees until the tabs engage (Fig. 69), then tighten it 5
more degrees by turning it counter clockwise using the
Fig. 69 -ENGAGING the
RETAINING RING TABS
Battery Hatch Tool (Fig. 70).
 While tightening the Retaining Ring, exert continuous
inward pressure on it until it is secured in the proper
position. A small symbol located on the Ring should be
aligned with the Locked symbol located on the Housing
(Fig. 70a)

Inspection
 Activate the unit and watch carefully as it performs a full
diagnostic and battery check, and enters Surface Mode.
 Observe the LCD display to ensure it is consistently clear and
sharp in contrast throughout the screen.
WARNING: If there are any portions of the display
missing or appearing dim, or if a Low Battery condition is indicated, return your Veo 100Nx to an Authorized Oceanic Dealer for a complete evaluation before
attempting to use it.
RETURNING THE MODULE TO BOOT
 If the Boot was fitted with a Spacer and it was previously
removed, replace the Spacer into the Boot.
 Orient the Module over the opening in the Boot, and dip the
bottom edge into it while pressing the top edge with the palm
of your hand. Stop pressing when the bottom edge of the
Module has just entered the Boot.
 Correct the alignment of the Module as needed so that it is
straight.
 Press the Module completely into place with your thumbs,
Responsible

watching the alignment, until it snaps into place.
ALTITUDE COMPENSATION
Atmospheric pressure decreases as Altitude increases above sea level. Weather systems
and ambient temperature also affect barometric pressures. Consequently, depth reading
instruments that do not compensate for the decrease in ambient pressure indicate depth
readings shallower than the depth they are actually at.
The Veo 100Nx automatically compensates for decreased ambient pressures for Altitudes
between 2,000 (610 meters) and 14,000 feet (4,270 meters). Its program contains a
high altitude algorithm that reduces no decompression and oxygen exposure limits to add
a larger zone of caution.
The Veo 100Nx senses ambient pressure when it is activated, every 15 minutes while it is
activated, or every 30 minutes when it is not activated. At an Altitude of 2,000 feet (610
meters), it will automatically recalibrate itself to measure depth in feet of fresh water rather
than feet of sea water. It will then readjust the no decompression and oxygen limits at
additional intervals of 1,000 feet (305 meters). Therefore, when returning to lower Altitudes, diving should not be conducted until the unit automatically clears of any residual
nitrogen and oxygen loading and resets to operate at the new lower Altitude.
WARNING: The Veo 100Nx will not sense ambient pressures or provide
Altitude compensation when it is wet. DO NOT dive at any different Altitude
until the unit shuts off and is reactivated at the new Altitude.
If the unit is activated at elevations higher than 14,000 feet (4,270 meters), it
will perform a diagnostic check followed by immediate shutdown.
