INTRODUCTION
Welcome to Oceanic and thank you for choosing the Veo 200 or Veo 250 !
It is extremely important that you read this Operating Manual in sequence and understand
it completely before attempting to use the Veo 200/250. It is equally important that you
read the Oceanic Dive Computer Safety and Reference Manual (Doc. No. 12-2262)
provided with your Veo 200/250. It contains information that you must become familiar
with prior to diving with your Veo 200/250.
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 200 and 250 are configured with the same features and functions. The differ-
ence between them is the location of the 2 Control Buttons (page 8). The Veo 200 is
designed for mounting in a Console Boot and has both Buttons on the front. The Veo 250
is designed to wear on the wrist and has 1 button on the front and 1 on the right side.
INTERACTIVE CONTROL CONSOLE
The Control Buttons, referred to as the Interactive Control Console allow you to select
display options and access specific information when you want to see it. They are also
used to enter settings, activate the Backlight, and acknowledge the Audible Alarm.
The Left button of the Veo 200 and Front button of the Veo 250 are referred to as the
Advance
referred to as the Select button. The terms used in this manual are Left/Front (Advance)
and Right/Side (Select) referring to the Veo 200/250.

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 decom-
pression 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 green No Decompres-
sion (normal) zone, a yellow Caution zone (also No Decompres-
sion), 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.
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).
Oxygen Accumulation Bar Graph (O2BG)
The O2 Bar Graph (Fig. 2a) represents oxygen loading, show-
ing the maximum of either per dive accumulated oxygen, or 24
hour period accumulated oxygen.
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
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).
Green is a 'normal' rate, yellow a 'caution' rate, and red is 'Too
Fast'.
The segments of the Variable Ascent Rate Indicator 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 feet per
minute (18 meters per minute). At depths of 60 feet
(18 meters) and shallower, ascent rates should not
exceed 30 feet per minute (9 meters per minute).

Ceiling Stop
can be viewed by pressing the Left/Front (Advance) button.
Time and Date 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 (Fig. 5a) and a
display is located in the lower portion of the
second time display
(Fig. 5b) is
located in the center/right. Both displays are identified by a
clock icon.
Time of Day can be set for 12 hour format (Am/Pm) or 24
hour format.
Date
(Month and Day) is displayed in the center/left portion of
the screen (Fig. 6a) only to identify dive data while it is viewed
in the Log Mode. Year is only displayed when setting the Date.
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.

AUDIBLE ALARM
LED Warning Light
A red LED Warning Light is synchronized with the Audible Alarm
and will flash when the Alarm emits a tone. They will turn OFF
when the Alarm is acknowledged, or Set OFF (a user setting).
When warning situations activate the Alarm, the unit will emit a
beeping tone for several seconds until it times out, or until the
situation is corrected, or it is acknowledged by pressing the
Left/Front (Advance) button for 2 seconds. The Alarm will sound
again upon reentry into the warning situation, or entry into
another type of warning situation.
Situations that will sound the Alarm, if it is turned ON (a user setting), include -
Entry into Decompression Mode
PO2 => than the Max PO2 Alarm (a user setting), or => 1.60 ATA.
Descent deeper than the Max Depth Alarm (a user setting).
Nitrogen Bar Graph Alarm (a user setting).
Dive Time Remaining Alarm (a use setting).
Elapsed Dive Time Alarm (a use setting).
O2 Accumulation => allowable per dive limit, or limit for a 24 hour period.
Ascending above a required Decompression stop depth for less than 5 minutes (Condi-
tional Violation).
Ascent rate exceeds 60 feet/minute (18 meters/minute) if greater than 60 feet (18
meters), or 30 feet/minute (9 meters/minute) at 60 feet (18 meters) and shallower.
During the following situations, the beeping tone will be followed by a second
beeping tone that will not turn off when acknowledged, even if it was user Set OFF
-
Ascending above a required Decompression stop depth for more than 5 minutes
(Delayed Violation).
Decompression requires a ceiling stop depth of 70 feet/21 meters or deeper.

BACKLIGHT
To activate the Backlight - press the Right/Side (Select) button.
While on the surface or during a dive, the Smart Glo®
feature senses the intensity of natural light present. If a low
level of light is present, the Backlight will activate and
illuminate the display for 5 seconds, or the Duration time (a
user setting).
The Backlight does not operate during a Low Battery condi-
tion.
Press the button again to activate as desired.
POWER SUPPLY
The Veo 200/250 utilizes one (1) type CR 2450 Lithium 3 volt
cell that should provide 300 hours of continuous, or 50 activa-
tion periods, of operation. If you conduct 1 dive each time the
unit is activated, you should obtain approximately 50 dives. If
you conduct 3 dives each time the unit is activated, you should
obtain approximately 150 dives.
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. 8a). The Indicator
a
will not be displayed during Dive Mode(s).
Low Battery Condition
Voltage level is checked upon activation and every 10 minutes
during operation.
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 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 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 (Fig. 9) 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 past 4 feet (1.2
meters). 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 appear after the dive in Surface Mode.
Fig. 9 -Low Battery Condition
17
FO2 MODE
After Activation, the Veo 200/250 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 %).
Fig. 10 - FO2 set for Air
Fig. 11 - FO2 set for 21%
18
When set with an
FO2 value of 'Air'
(Fig. 10), the Veo 200/
250 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,
warnings, and the O2 Bar Graph will not appear on the display
for that dive, or subsequent dives, unless FO2 is set for a numeri-
cal value (21 - 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. 11), 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 reacti-
vated.
Setting FO2 is described on Page 25.
FO2 50% Default
If the Default is set to ON
(Fig. 12) and FO2 is set to a
value 'greater than 21%', the FO2 set point value will auto-
matically 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.
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. 13), the FO2 value for
repetitive dives remains the same as previously set until the set
point is manually changed.

NOTICE
WET ACTIVATION
The Veo 200/250 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.
20
WARNING: Prior to diving with the Veo 200/250,
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.

ACTIVATION
WARNING: If the unit is activated at elevations
higher than 14,000 feet (4,267 meters), it will perform a diagnostic check and immediately shutdown.
To Activate the Veo 200/250, press and release the Left/Front
(Advance) Button.
Upon manual activation, the unit will enter Diagnostic
Mode (Fig. 14), 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.
When the Right/Side (Select) button is held depressed
when the Diagnostic countdown reaches 00, an External
Access request is initiated. A Serial Number screen ap-
pears displaying the units Serial Number and firmware
code Revision Number as long as the button is held de-
pressed (Fig. 15). Upon releasing the button, the unit shuts
Off.
After manual activation, 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 recalibrate itself to measure depth in feet of fresh water
instead of feet of sea water.
Backup Activation (only if Water Activation is set ON)
As a backup, the Veo 200/250 will also automatically activate
by water contact. This is accomplished by bridging the gap
between contacts located on the Button stems and back of the
case. The graphic H2O that will be displayed as an indication
is described later.
If no dive is made within 2 hours after initial activation, the unit
will automatically deactivate. If the wet contacts are still
bridged, the unit will reactivate and display the H2O graphic.
SURFACE MODE
Surface Mode (Fig. 16A), identified by the Surface Time icon,
follows Diagnostic Mode after Activation. Information includes
Dive Number '0' (no dive made yet), Temperature (and icon),
Time of Day (with icon), the Battery Consumption Indicator, and
Surface Time (with flashing colon).
If the wet contacts are bridged, the graphic 'H2O' will appear in
place of the dive number '0' (Fig. 16B). After the unit is rinsed
and dried, '0' will replace 'H2O'.
Press the Left/Front (Advance) button to access a sequence
that includes Plan, Fly, DeSaturate, and Log Modes.
Press the Right/Side (Select) button momentarily (less than 2
seconds) to activate the Backlight.

SET MODES
To help simplify the operations you might perform at the dive
site, settings are divided into 2 categories. Set Mode #1 in-
cludes several settings that you would change more often and
Set Mode #2 includes those items not likely to change once you
set them. Set Mode 2 can be accessed by first entering settings
in Set Mode 1, or by bypassing Set Mode 1.
After gaining access to Set Mode 1 or Set Mode 2, settings can
be made in sequence one after the other, or you can access a
specific item that you want to set, bypassing others.
