FEATURES and DISPLAYS

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 used to enter settings.

Be a - RESPONSIBLE DIVER at all times.

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 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.

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

Fig. 2 - O2BG and VARI

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).

Deeper than 60 FT (18 M)

Segments Ascent Rate = Displayed FPM MPM 0 0-20 0 - 6 1 21-50 6. 5-15 2 51-60 15.5-18 3 >60 >18

Segments Ascent Rate = Displayed FPM MPM 0 0-10 0 - 3 1 11-25 3.5-7.5 2 26-30 8-9 3>30>9

VARI

The segments of the Variable Ascent Rate Indicator 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 feet per minute (18 meters per minute). At depths of 60 FT (18 M) and shallower, ascent rates should not exceed 30 feet per minute (9 meters per minute).

ALPHA / NUMERIC DISPLAYS

Each numeric and graphic display represents a unique piece of information. It is imperative that you understand the formats, ranges, and values of the information represented to avoid any possible mis- understanding that could result in error.

Depth Displays

During a dive, the

Current Depth

display (Fig. 3a), indicates

depths from 0 to 330 FT (99.9 M) in 1 FT (0.1 M) increments.

By accessing alternate Main Dive Displays, the

Depth

reached during that dive will be displayed in the center/

Maximum

left portion of the display (Fig. 4a).

During a Decompression Dive, the required

Depth

is displayed in the center of the screen. Maximum Depth

Ceiling Stop

can then be viewed by pressing the button.

Fig. 3 - CURRENT DEPTH

Fig. 4 - MAX DEPTH

Fig. 5 - TIME

Time 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.

Fig. 6 - TEMPERATURE

Temperature Display

Ambient Temperature

is displayed in the center/left portion of the screen (Fig. 6a) while in the Surface Mode and Log Mode, and can be viewed as part of an Alternate Display when the button is pressed while in a dive mode.

NOTE: The Informational Displays are described in detail as the various operating modes they appear in are presented throughout this manual.

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.

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. 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 re- placed prior to conducting any further dives.

Fig. 7 - BATTERY ICON

Fig. 8 - LOW BATTERY

 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 into Surface Mode.

FO2 MODE

After Activation, the Veo 100Nx will operate as an AIR com- puter 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 subse- quent 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 reacti- vated.

Setting FO2 is described on Page 21.

Fig. 9 - FO2 Set for AIR

Fig. 10 - FO2 Set for 21%

FO2 50% DEFAULT

Fig. 11 - FO2 Default ON

Fig. 12 - FO2 Default OFF

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 automati- cally 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 nitro- gen 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.

ACTIVATION and SETUP

ACTIVATION

WARNING: If the unit is activated at elevations higher than 14,000 feet (4,270 meters), it will perform a diagnostic check and immediately shutdown.

To Activate the Veo 100Nx, press and release the Button.

Fig. 13 - DIAGNOSTIC MODE

Fig. 14 - SERIAL NUMBER

 Upon manual activation, the unit will enter Diagnostic

Mode (Fig. 13), 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 button is held depressed and the Diagnostic

countdown reaches 00, a Serial Number screen appears displaying the units Serial Number and firmware code Revision Number as long as the button is held depressed (Fig. 14). 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 at that higher Alti- tude.

Wet Contact Activation (only if Wet Activation is set ON)

The Veo 100Nx will also automatically activate by Wet Contact. This is accomplished by bridging the gap between contacts located on the Button's stem and back of the 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 and display the H2O graphic.

SURFACE SEQUENCE

While on the surface, the unit will automatically scroll through a Sequence of displays including -

 Surface Mode  Fly Mode  DeSat Mode  Plan Mode

As the Surface Sequence is scrolling, you can use the button to access Log Mode and Set Mode.

SURFACE MODE

Surface Mode, identified by the Surface Time icon (Fig. 15a), follows Diagnostic Mode after Activation. Information includes Dive Number (0 if no dive made yet), Temperature (and icon), Time of Day (with icon), the Battery Indicator, and Surface Time (with flashing colon).

Fig. 15 - SURFACE MODE

(module is dry)

If the wet contacts are bridged, the graphic H2O will appear in place of the dive number 0 (Fig. 16). After the unit is rinsed and dried, 0 will replace H2O.

While the Surface Sequence is scrolling -

 press/release the button (< 2 seconds) to access Log Mode.  depress the button for 2 seconds to access Set Mode.

After gaining access to Set Mode, settings can be made in sequence one after the other, or you can access a specific item that you want to set, bypassing others.

Set Mode Access/Timing

To access Set Mode while the Surface Sequence is scrolling, press/release the button momentarily (< 2 seconds).

 Upon entry into Set Mode, the Set FO2 screen will be

displayed with the Set Point flashing (Fig. 17).

 If the button is not pressed during a 2 minute period while in

the Set Mode, the unit will revert to Surface Mode and resume the Surface Sequence scroll.

TO SET - FO2

Each time the unit is activated, FO2 will be automatically set for a default value of AIR which can then be changed to values between 21 and 50% in increments of 1%.

 While the Surface Sequence is scrolling, depress the button

for 2 seconds.

 Release the button when the FO2 screen appears with the

Set Point flashing (Fig. 18).

 Press/release the button repeatedly to increase the FO2

value from 21 to 50% in increments of 1%, then display AIR again.

 For each FO2 value that appears, the display indicates the

Maximum Depth that can be achieved for a PO2 of 1.60 ATA (Fig. 19a), or the PO2 Alarm Set Point. If FO2 is set for AIR, no Depth value will be displayed.

 Depress the button for 2 seconds to accept the FO2 Set Point

displayed and advance to the Set Wet Activation screen.
