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 programs within the VEO 1.0 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 1.0 dive computer
model is based upon the latest research and experiments in decompression theory. Still, using the VEO 1.0,
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.

CONTROL BUTTON
The Control Button allows you to select display options and ac-
cess specific information when you want to see it.
BAR GRAPHS
TLBG (Tissue Loading Bar Graph)
The TLBG (Fig. 1a) represents tissue loading of nitrogen, show-
ing your relative no decompression or decompression status. As
your depth and elapsed dive time increase, segments will add to
the TLBG, and as you ascend to shallower depths, the segments
will begin to recede, indicating that additional no decompres-
sion time is allowed for multilevel diving.
The TLBG monitors 12 different nitrogen compartments simultane-
ously and displays the one that is in control of your dive.
It is divided into a No Decompression zone (up to 3 segments
displayed), a Caution zone (4 segments displayed, also No
Deco), and a Decompression zone (all 5 segments displayed).
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.

VARI (Variable Ascent Rate Indicator)
The VARI (Fig. 2a) provides a visual representation of ascent
speed (i.e., an ascent speedometer).
The segments of the VARI represent two sets of speeds which
change at a reference depth of 60 FT (18 M). Refer to the chart
for segment values.
WARNING: At depths greater 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).

ALPHA / NUMERIC DISPLAYS
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.
Current Depth (Fig. 3a) and Max Depth (Fig. 3b) are both
displayed from 0 to 330 FT (100 M) in 1 FT (.1 M) increments
on the Main Dive screens.
During cautionary situations and while at Stops (Deep, Safety,
or Deco), Max Depth is replaced with more critical information
such as Stop Depth (Fig. 4a), and can be seen by temporarily
accessing an Alternate screen (Fig. 5a).
Time displays are shown in various formats.
• Minute only - Dive Time Remaining (Fig. 3c), Elapsed Dive
Time, Deco Stop.
• Minute:Second - Deep Stop, Safety Stop (Fig. 4b).
• Hour:Minute - Time of Day, Surface Interval.
To help differentiate between the formats used, min and sec
icons are displayed with applicable times.

Ambient Temperature (Fig. 6a) can be viewed by accessing an
Alternate screen while on the surface or during dives.
Altitude (Fig. 6b) is also displayed on the Alternate screen when
at elevations above 3,000 feet. Altitude is not displayed at Sea
level, which extends up to 3,000 feet elevation.
Altitude ranges displayed include -
EL2 - 3,001 to 5,000 feet (EL = Elevation Level)
EL3 - 5,001 to 7,000 feet
EL4 - 7,001 to 9,000 feet
EL5 - 9,001 to 11,000 feet
EL6 - 11,001 to 13,000 feet
EL7 - 13,001 feet and above
POWER SUPPLY
The VEO 1.0 utilizes one (1) type CR 2450 Lithium 3 volt cell.
Expected use life is approximately 100 hours if (1) 1 hour dive
per day is conducted each time the unit is activated, up to 300
hours if (3) 1 hour dives per day are conducted.

Low Battery
Voltage level is checked upon activation and every minute dur-
ing operation on the surface.
• When voltage decreases to the warning level (2.75 volts),
the icon is displayed solid on the Surface Main (Fig. 7a).
• Upon decreasing to a voltage level that will no longer sus-
tain proper operation (2.50 volts), the icon will flash 5 times
and the unit will shut off.
• If a low battery condition exists when the unit is activated
(by pressing the button), the graphic bAT and the icon will
appear flashing for 5 seconds and the unit will shut off.
• If the button is not pressed to activate the unit prior to a dive,
and a low battery condition exists, the icon will appear flash-
ing as a warning upon descent to 5 FT (1.5 M) and no other
information will be displayed.
• If a low battery condition occurs during a dive, there will
be sufficient battery power to maintain operation for the
remainder of that dive. The icon will appear, with the graph-
ics CHG and BAT alternating (Fig. 8), after the dive when
operation enters Surface Mode.

FO2 MODE
After Activation, the VEO 1.0 will operate as an Air computer
without displaying information associated with oxygen calcula-
tions, unless it is set for a percentage of oxygen (FO2) other than
Air (a numerical value between 21 and 50 %).
When set for Air (Fig. 9), the VEO 1.0 will perform calculations
the same as if FO2 were set for 21% oxygen, internally account-
ing for oxygen loading for any subsequent Nitrox dives. How-
ever, oxygen related displays and warnings 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 a set option, 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 re-
main set at 21% for subsequent nitrox dives until FO2 is set to a
higher value, or until it automatically turns off and is reactivated.

Fig.11-FO2DEFAULTOFF
FO2 50% Default
If the Default is turned On and FO2 is set to a value greater than
21%, the FO2 Set Point will automatically revert to 50(%) 10
minutes after that dive.
FO2 must therefore be reset for each repetitive Nitrox dive, or
the value will automatically keep defaulting 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. 11), the FO2 value for repetitive
dives remains the same as previously set until it is changed.

ACTIVATION
WARNING: If the unit is activated at elevations
higher than 14,000 feet (4,267 meters), it will per-
form a diagnostic check and immediately shutdown.
To Activate the VEO 1.0, press and release the Button.
• The unit will enter Diagnostic mode (Fig. 12), displaying all
segments of the LCD as 8's, followed by dashes (- -), then a
countdown from 9 to 0. The display and battery voltage to
ensure that everything is within tolerance and functioning
properly.
• After manual activation, it will also check the ambient baro-
metric pressure, and calibrate its present depth as zero.
Beginning at elevations of 3,001 feet (916 meters), it will
recalibrate depth and adjust calculations every 2,000 feet
(610 meters).
The VEO 1.0 will also automatically activate by water contact.
This is accomplished by bridging the gap between contacts
located on the button and case.
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.
