  • Page 8: Introduction

    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.

  • Page 9: Bar Graphs

    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.

  • Page 10: Oxygen Bar Graph (O2Bg)

    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.

  • Page 11: Alpha / Numeric Displays

    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 Fig.

  • Page 12: Time Displays

    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).

  • Page 13: Power Supply

    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.
