  • Page 10 It is extremely important that you read this Operating anual in sequence and understand it completely before attempting to use the anta as a dive computer. It is equally important that you read the AERIS Dive Computer Safety and Refer- ence anual (Doc. No. 12-7203) provided with your anta. It contains informa- tion that you must become familiar with prior to diving with your anta.

  • Page 32 BAR GRAPH The anta features one shared Bar Graph that represents either nitrogen loading, or when accessed, oxygen accumula- tion. By default, the Bar Graph (Fig. 23a), referred to as the Nitrogen Bar Graph (NIBG), represents your relative no decompression or decompression status. As your Depth and Elapsed Dive Time increase, segments will add to the NIBG, and as you ascend to shallower depths, the segments of the NIBG will begin to recede, indicating that...
  • Page 33 Displays associated with oxygen and the O2 Bar Graph will be displayed if FO2 has been set at a value other than 'Air' (e.g., a numerical value) and the Alternate screen that displays oxygen related data is accessed. When the oxygen data screen is accessed during a NOR dive, the Bar Graph will show the maximum of either per dive accumulated oxygen or 24 hour period accumulated oxygen.
  • Page 34 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. Within the available NOR ode parameters that can be set (described later) are a NIBG Alarm and a Conservative Factor which if set ON reduces No Decompression times allowed.
