INTRODUCTION

Welcome to Oceanic and thank you for choosing the Veo 180Nx !

It is extremely important that you read this Operating Manual in sequence and understand it completely before attempting to use the Veo 180Nx.

It is equally important that you read the Oceanic Dive Computer Safety and Reference Manual (Doc. No. 12-2262) provided with your Veo 180Nx. It contains information that you must become familiar with prior to diving with your Veo 180Nx.

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 and activate the Backlight.

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 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).

Variable Ascent Rate Indicator

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

Page 11

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 feet (99.9 meters) in 1 foot (.1 meter) increments.

Fig. 3 - Current Depth

By pressing the button, the

Maximum Depth

reached during that dive will be displayed in the center/left portion of the display (Fig. 4a).

 When the unit is set to operate as a digital depth gauge/

timer (referred to as User Set Gauge Mode), the Depth Display range is 'extended' to 399 feet (120 meters). At depths greater than 99.9 meters it will indicate metric values in increments of 1 meter.

During a Decompression Dive, the required

Depth

is displayed in the center of the screen. Maximum Depth

Ceiling Stop

Fig. 4 - Maximum Depth

Page 12

Fig. 5 - Time Displays

Fig. 6 - Date Display

can be viewed by pressing the 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.

Page 13

Temperature Display

Ambient Temperature

is displayed in the center/left portion

of the screen (Fig. 7a) 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.

AUDIBLE ALARM

When warning situations activate the Alarm, the unit will emit a beeping tone for 10 seconds. The Alarm will sound again upon reentry into the warning situation, or entry into another type of warning situation. A red LED Warning Light is synchronized with the Audible Alarm and will flash when the Alarm emits a tone.

Situations that will activate the Alarm include -

 Entry into Decompression Mode  PO2 => than the Max PO2 Alarm or => 1.60 ATA.  Depth => 330 feet/99.9 meters.  O2 Accumulation => 300 OTU.  Ascending above a required Decompression stop depth.  Ascent rate exceeds the allowed limit.  Decompression requires a stop depth=> 70 feet/21 meters.  Being on the surface for 5 minutes after a Conditional Viola-

tion (Permanent Violation).

Fig. 7 - Temperature Display

Page 14

Fig. 8 - Battery Indicator

BACKLIGHT

To activate the Backlight while on the surface, press and release the button momentarily (less than 2 seconds). During a dive depress the button for 2 seconds

 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 illumi- nate the display for 10 seconds.

 The Backlight does not operate during a Low Battery condi-

tion.

 Press/release the button again to activate as desired.

POWER SUPPLY

The Veo 180Nx 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. 8a). The Indicator

Page 15

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. 9) as a warning that the Battery is to be re- placed 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 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

Page 16

FO2 MODE

After Activation, the Veo 180Nx 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 %).

Fig. 10 - FO2 set for Air

Fig. 11 - FO2 set for 21%

When set with an

FO2 value of 'Air'

(Fig. 10), the Veo 180Nx 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 23.

Page 17

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.

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.

Fig. 14 - Diagnostic Mode

Fig. 15 - Serial Number

To Activate the Veo 180Nx, press and release the 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 button is held depressed when the Diagnostic

countdown reaches 00, an External Access request is initiated. 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. 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.

Page 21

Backup Activation (only if Water Activation is set ON)

As a backup, the Veo 180Nx will also automatically activate by water contact. This is accomplished by bridging the gap be- tween contacts located on the Button 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. 16a), follows Diagnostic Mode after Activation. Information includes Dive Number '0' (no dive made yet), Temperature (and icon), Time of Day (with icon), the Battery Indicator, and Surface Time (with flashing colon).

PRE DIVE PLANNING SEQUENCE

The Pre Dive Planning Sequence (PDPS), which appears after Surface Mode prior to the first dive of a new activation period, provides a sequence of theoretical dive times available for depths ranging from 30 feet (9 meters) to 190 feet (57 meters) in 10 foot (3 meter) increments.

Depth NDL feet (meters) hours:mins 30 (9) 4:20 (4:43) 40 (12) 2:17 (2:24) 50 (15) 1:21 (1:25) 60 (18) :57 (:59) 70 (21) :40 (:41) 80 (24) :30 (:32) 90 (27) :24 (:25) 100 (30) :19 (:20) 110 (33) :16 (:17) 120 (36) :13 (:14) 130 (39) :11 (:11) 140 (42) :09 (:09) 150 (45) :08 (:08) 160 (48) :07 (:07) 170 (51) :07 (:06) 180 (54) :06 (:06) 190 (57) :05 (:05)

NDLs at Sea Level

for an Air Dive

(no dive made yet)

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 decompres- sion 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.

Page 35

 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 con- trolled), or predicted oxygen tolerance limits (OTLs) based upon either a single dive exposure or your 24 hour accumu- lation 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. 30), that

next dive is calculated to be controlled by nitrogen loading.

 If the O2BG and O2 symbol are displayed (Fig. 31), it is

calculated to be controlled by oxygen loading.

NOTE: The Veo 180Nx 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 segments of the O2BG will be displayed flashing .

Depth/Time values will not appear until the O2BG recedes into the green (normal) zone (i.e., your daily O2 dosage decreases an amount equivalent to the amount accumulated during the latest dive completed).

Fig. 33 - Ascent Too Fast

TISSUE LOADING BAR GRAPH (TLBG) (Fig. 32a)

As your Depth and Elapsed Dive Time increase, the Tissue Loading Bar Graph (TLBG) will add segments (green toward red) to represent the absorption of nitrogen.

While ascending to shallower depths, the number of segments displayed will begin to recede, offering a graphic representation of your multilevel diving capability.

OXYGEN ACCUMULATION BAR GRAPH (O2BG) (Fig. 32b)

If FO2 was set for a numerical value (nitrox), the Oxygen Accu- mulation Bar Graph (O2BG) will add segments (green toward red) to represent oxygen accumulation for that dive, or 24 hour period, whichever amount is greater.

VARIABLE ASCENT RATE INDICATOR (Fig. 32c)

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), it will enter the red (Too Fast) zone (Fig. 33) and you will be alerted by the graphic TOO FAST Fig. 33a), all segments of the bar graph flashing, an Audible alarm and the red LED Warning Indicator. The warnings will stop when your Ascent Rate is slowed.

Page 37

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 dis- played (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 automatically revert to the Main Display after 3 seconds.

To activate the Backlight, press the button for 2 seconds.

 The display will be illuminated 10 seconds.  The Backlight will not activate during a Low Battery Condi-

tion.

NO DECOMPRESSION DIVE MODE

The Veo 180Nx will enter the No Decompression Dive Mode when you descend deeper than 4 feet (1.2 meters).

Mode

The Safety Stop will be displayed until the countdown times out, or the a descent is made below 30 feet (10 meters), or the diver surfaces. There is no Penalty if the diver surfaces prior to com- pleting the Safety Stop.

Information includes Current Depth, Stop Depth (15 feet or 4.5 meters), Stop Bar icon, Countdown Timer, Dive Time Remaining, and applicable bar graphs.

DECOMPRESSION DIVE MODE

The Veo 180Nx is designed to help you by providing a repre- sentation of how close you are to entering decompression. Decompression Dive Mode (Fig. 39) activates when theoretical No Decompression time/depth limits are exceeded.

Upon entering Decompression Mode, the Mode icon will change from No Deco to Deco, the Audible Alarm will sound and the red LED Warning Indicator will flash for 10 seconds.

Page 41

 The UP Arrow and Deco Bar will flash if you are greater than

10 feet (3 meters) deeper than the Required Stop Depth.

 Once you are within 10 feet (3 meters) of, and below, the

required Stop Depth, both Arrows and the Bar appear solid.

Total Ascent Time

Total Ascent Time (Fig. 40a) includes Stop Times required at all required decompression ceilings and vertical Ascent Time calculated at 60 feet (18 meters) per minute for depths deeper than 60 feet (18 meters), and 30 feet (9 meters) per minute for depths of 60 feet (18 meters) and shallower.

Managing Decompression Stops

To fulfill your decompression obligation, you should make a safe controlled ascent to a depth slightly deeper than, or equal to, the Required Ceiling Stop Depth indicated (Fig. 40b) and decom- press for the Stop Time indicated (Fig. 40c).

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. 40d) than the Required Stop Depth indicated until the next shallower Stop Depth appears. Then, you can slowly ascend to, but not shal- lower than that indicated ceiling Stop Depth.

Conditional Violation Mode

f you ascend shallower (Fig. 45a) than a Required

Decompression Ceiling Stop Depth

displayed (Fig. 45b), the Down Arrow, Deco Bar, and Total Ascent Time will flash until you descend below the Required Stop Depth. Also displayed will be Current Depth and applicable bar graphs.

The Audible Alarm will sound and the red LED will flash as a warning for 10 seconds.

If you descend below the required decompression ceiling before 5 minutes have elapsed, the Veo 180Nx will continue to function in Decompression Dive Mode. In this case, no off-gassing Credit will be given, and for each minute above the ceiling 11/ minutes of

Penalty Time

will be added to Required Stop Time.

Fig. 45 - Conditional

Violation

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 decompression Stop Depths and Time will decrease toward zero, then the Tissue Loading Bar Graph will recede into the yellow Caution Zone and the Veo 180Nx will revert to the No Decompression Dive Mode.

Page 45

NOTE: Upon entry into Violation Modes, the red LED will flash and the Audible Alarm will sound.

Delayed Violation Mode #1 (Fig. 46)

If you remain above the Required Ceiling Stop Depth for 'more than 5 minutes',

the TLBG and Total Ascent Time will flash until you descend below the Required Stop Depth. This is a continuation of a Conditional Violation.

Delayed Violation Mode #2 (Fig. 47)

The Veo 180Nx cannot calculate decompression times for Stop Depths much greater than 60 feet (18 meters) and offers no indication of how much time spent underwater would result in the need for a greater Stop Depth.

If your Decompression obligation requires a Ceiling Stop Depth 'between' 60 feet (18 m) and 70 feet (21 m),

the 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 feet (18 meters) 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. 48)

If you descend deeper than 330 feet (99.9 meters),

the TLBG segments will flash, and the Current Depth and Max Depth displays will only indicate 3 dashes ( - - -).

Fig. 48 - Delayed Viola #3

Fig. 49 - Viola Gauge Mode

Upon ascending above 330 feet (99.9 meters), 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 Mode and Gauge Mode

During a Dive, if a ceiling much greater than 60 feet (18 meters) is required, an

Immediate Violation Mode

will be entered. This situation would be preceded by entering Delayed Violation Mode #2.

The Veo 180Nx would then operate with limited functions in

a Delayed Violation occurred.

On the surface,

Gauge Mode

displays the Dive Number, Temperature, Time of Day, Surface Interval, and bar graphs flashing (Fig. 50). 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 180Nx operation can resume with full features and functions.

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 yellow Caution Zone of 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 red O2 (Danger) Zone (Fig. 53). The red LED will flash, the Audible Alarm will sound), and the UP Arrow and the full O2 Bar Graph will flash as a warning until the level of oxygen decreases below the limit.

UNEXPECTED LOSS OF DISPLAYED INFORMATION

If your Veo 180Nx 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 pushing the No Decompression and Oxygen Accumulation Limits, and a critical reason to avoid entering Decompres- sion.

POST DIVE SURFACE MODE

When you ascend to 3 feet (1 meter) or shallower, the Veo 180Nx will enter Surface Mode and begin counting your surface interval.

TRANSITION PERIOD

The first 10 minutes is, in affect, a Transition Period during which time the following information is displayed (Fig. 56):

 Number of that dive (during that activation period)  Temperature (ambient)  Time of Day and icon  Battery Consumption Indicator  Surface Interval time (colon flashing) and icon (flashing)  TLBG indicating current nitrogen loading  O2BG indicating current oxygen accumulation (if nitrox)

During the Transition Period, Log Mode can be accessed. No other modes (e.g., PDPS, Fly, Desat, Set, PC) are accessible.

To view the Log for that dive (Fig. 57), press and 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.

Page 53

Press and release the button momentarily (< 2 seconds) to activate the Backlight.

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 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 (Fig. 58) indicat- ing that the Dive and Transition Period are completed, and a subsequent descent will be considered a new dive.

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 have full access to Log and Set modes.).

Press and release the button momentarily (< 2 seconds) to activate the Backlight.

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. 59) always begins at 23:50 (hr:min) and the Desat countdown (Fig. 60) at 23:50 (maximum).

Fig. 59 - Time to Fly

Fig. 60 - Time to Desaturate

If a Violation occurred during the dive a single dash ( - ) will appear instead of the letters FLY. DeSat time will not be dis- played.

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.

Page 55

Pre Dive Planning Sequence (PDPS)

After a dive, the PDPS provides 'adjusted' No Decompression Limits (Fig. 61) based on residual nitrogen calculated to be remaining from that dive and previous dives in the same series.

Log Mode

The Veo 180Nx will store up to 24 dives in its Log for viewing.

Each dive has 3 Log screens - Dive Identifier (Preview), Dive Data, and O2 Data (if a Nitrox dive).

Once the Log is full (24 dives), each subsequent dive will then overwrite the oldest dive stored in the Log. It is therefore sug- gested that you transfer the Log's data to your log book at the end of each day of diving, or Download it to the OceanLog PC program files.

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.

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.

NOTE: The procedures that follow must be closely adhered to. Damage due to improper battery replacement is not covered by the unit's 2 year warranty.

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 pres- sure from underneath, working it out slowly.

CAUTION: The procedure that follows must be closely adhered to. Damage due to improper Battery replacement is not covered by the limited 2 year

warranty.

Page 65

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 calculations and settings, will be retained for repetitive dives.

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. 71) 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. 71 - Ring Removal

Page 66

Battery Removal

 Remove the Retaining Bar located across the lower portion of

the Battery (Fig. 72a).  Remove the Hatch O-ring. DO NOT use tools  Using care not to damage the Battery Contacts (Fig. 72b/c),

slide the Battery up and out of the Battery Compartment.

Inspection

 Closely check all of the sealing surfaces for any signs of

damage that might impair proper sealing.  Inspect the Button, Lens, and Housing to ensure they are not

cracked or damaged.  If it is necessary to clean the Battery Compartment, flush it

and all components with a solution of 50% white vinegar

and 50% fresh water. Rinse with fresh water, and allow to

dry overnight, or blow dry with a hair dryer (set at 'no heat').

WARNING: If damage or corrosion is found, return your Veo 180Nx 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. 73).

 Orient the Retaining Bar across the lower portion of the

Battery and carefully push it down into position (Fig. 74).

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.

 Lightly lubricate the new Hatch O-ring with silicone grease

and place it on the inner rim of the Battery Hatch (Fig.

75). Ensure that it is evenly seated.

 Slide the Hatch Retaining Ring, top portion first (small

opening), onto your thumb.

 Carefully place the Battery Hatch (with O-ring) into posi-

tion on the rim of the Battery Compartment, then press it 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.

grees until the tabs engage (Fig. 76), then tighten it 5 more

degrees by turning it counter clockwise using the Battery

Hatch Tool (Fig. 77).  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. 77a)

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 180Nx to an Authorized Oceanic Dealer for a complete evaluation before attempting to use it.

Page 69

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,

watching the alignment, until it snaps into place.

Page 70

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 180Nx automatically compensates for decreased ambient pressures for Altitudes between 2,000 (610 meters) and 14,000 feet (4,267 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 180Nx 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 Alti- tudes, 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 180Nx 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 (4,267 meters), it will perform a diagnostic check followed by immediate shutdown.
