Summary of Contents for Oceanic Veo 200

  • Page 1 OCEANIC ® Veo 200/250 dive computers operating manual...
  • Page 2 Display (U.S. Patent no. 5,845,235) is owned by Suunto Oy (Finland). DECOMPRESSION MODEL The programs within the Veo 200/250 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.
  • Page 5 Pay special attention to items marked with this Warning symbol...

    FEATURES and DISPLAYS...
  • Page 9 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 button. The Right button of the Veo 200 and Side button of the Veo 250 are referred to as the Select button.
  • Page 10 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.
  • Page 11 The O2 Bar Graph (Fig. 2a) represents oxygen loading, showing 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 de- creases, it will begin to recede, indicating that additional expo- sure is allowed for that dive and 24 hour period.
  • Page 12 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 misun- derstanding that could result in error. 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.
  • Page 13 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).
  • Page 14 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 Left/ Front (Advance) button is pressed while in a dive mode. A red LED Warning Light is synchronized with the Audible Alarm and will flash when the Alarm emits a tone.

  • Page 16 • Press the button again to activate as desired. The Veo 200/250 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.
  • Page 17 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.
  • Page 18 (FO2) other than Air (a numerical value between 21 and 50 %). 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.
  • Page 19 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 Maxi- mum Depth that can be achieved with a PO2 of 1.60 ATA will also be displayed.

  • Page 46 (Fig. 42a) 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.
  • Page 47 (Fig. 43a) 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. (Fig. 44a) The Variable Ascent Rate Indicator (VARI) shows how fast you are ascending.

  • Page 51 The Veo 200/250 is designed to help you by providing a representation of how close you are to entering decompression. Decompression Dive Mode (Fig. 50) activates when theoretical No Decompression time/depth limits are exceeded. Upon entering Decompression Mode, the Audible Alarm will sound and the red LED Warning Indicator will flash for several seconds (unless set OFF), or until acknowledged.
  • Page 52 Then, you can slowly ascend to, but not shallower than that indicated ceiling Stop Depth. • While in Decompression Mode, the Veo 200/250 will automatically revert to the Main Display after 3 seconds unless the Left/Front (Advance) button is pressed to view another alternate display of information.

  • Page 55 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 200/250 will revert to the No Decom- pression Dive Mode.
  • Page 56 Required Stop Depth. This is a continuation of a Conditional Violation. (Fig. 57) The Veo 200/250 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.
  • Page 57 This situation would be preceded by entering Delayed Violation Mode #2. The Veo 200/250 would then operate with limited functions in Gauge Mode during the remainder of that dive and for 24 hours after surfacing. Gauge Mode turns the Veo 200/250 into a digital instrument without any decompression or oxygen monitoring functions.
  • Page 58 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 200/250 operation can resume with full features and functions.
  • Page 59 When partial pressure of oxygen (PO2) becomes equal to, or greater than, 1.40 ATA, or 0.2 ATA less than the PO2 Alarm set point (a user setting); the red LED warning will flash, the Audible Alarm will sound (unless set OFF), and the current PO2 value, PO2 symbol, O2 segment of the O2 Bar Graph, and UP Arrow will appear on the Main Display as a warning until PO2 decreases.
  • Page 60 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.
  • Page 61 When Digital Gauge Mode is set for ON, the Veo 200/250 will operate as a Digital Depth Gauge/Timer without performing nitrogen and oxygen calculations (Fig. 64A). While in this mode, the range of the Current and Maximum Depth displays are extended to 399 feet (120 meters) to accom- modate activities involving diving with advanced breathing gas mixtures or free diving beyond the normal depth limit of the unit.
  • Page 62 This dive computer is configured with a RESET feature that allows data to be cleared, including Nitrogen and Oxygen calculations, FO2 set point, and Log Mode entries. RESET PROCEDURE: • While in SURFACE MODE (new activation period or after a 10 minute post dive surface interval), press the Left/Front (Advance) button 1 time to access PLAN MODE.

  • Page 82 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.
  • Page 83 The Battery Compartment should only be opened in a dry and clean environment with extreme care taken to prevent the en- trance 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).
