  • Page 8 It is extremely important that you read this Operating Manual in sequence and understand it completely before attempting to use the Versa Pro. It is equally important that you read the Oceanic Dive Computer Safety and Reference Manual provided with your Versa Pro. It contains information that you must become familiar with prior to diving with your Versa Pro.
  • Page 9 The Tissue Loading Bar Graph (Fig. 2a) represents tissue loading of nitrogen, showing your relative no decompression or decompression 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 The O2 Bar Graph (Fig. 3a) 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 decreases, it will begin to recede, indicating that additional exposure is allowed for that dive and 24 hour period.
  • Page 11 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 misunderstanding that could result in error. During a dive, the Current Depth display (Fig. 4a), indicates depths from 0 to 330 feet (99.9 meters) in 1 foot (.1 meter) increments.
  • Page 12 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 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 Advance (Front) button is pressed while in a dive mode. If the Temperature exceeds a value of '99', two dashes ( - - ) will be displayed on the screen until the unit's temperature decreases to '99'.
