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 sick-
ness, 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.

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 ashes as the Audible sounds. It will turn Off when the Alarm is silenced. The Au-
dible 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)**.

15
• Delayed Violation (a Deco Stop Depth greater than 60 FT/18 M is required)**.
• 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 Gas Switch would expose the diver to PO2 => 1.60 ATA**.
A single short beep (which cannot be disabled) sounds when -
• 5 minutes elapse on the surface after a 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).
• FREE Dive Depth Alarms 1, 2, 3 (set sequentially deeper) - each 3 beeps 3 times.
• FREE Dive TLBG Alarm (Caution zone, 4 segments) - 3 beeps 3 times.
• Entry into Deco during a FREE Dive (Violation) - 3 beeps 3 times.
• Free Dive Mode Countdown Timer reaches 0:00 - 3 beeps 3 times.
During the following NORM Dive situations, the 10 second continuous tone will be fol-
lowed 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.
• Upon Surfacing 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 92 for more details relating to Oceanlog and PC Interface.

NORM Mode >> for Air and Nitrox SCUBA activity with 1 or 2 Gases.
GAUG Mode >> for SCUBA activity with no nitrogen/oxygen calculations.
FREE Mode >> for breath hold diving activity with calculations based on 21% O2.
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 se-
lected 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 2 FT (0.6 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 ashing.
• A descent during the rst 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 acti-
vate 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.
NORM Surface Main/Menu, button action
• A (< 2 sec) >> step forward through Menu items.
• A (hold) >> scroll forward through Menu items.
• M (< 2 sec) >> step back through Menu items.
• S (press) >> activate the SmartGlo Backlight.
• M (2 sec) or 2 min (of no button action) >> revert to Main.
