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.
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.
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 Fig.
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. Fig.
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).
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.
• 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.
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.
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 %).
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.

• 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 .
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.

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.
This situation would be preceded by entering Delayed Violation Mode #2. The Veo 180Nx 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 180Nx into a digital instrument without any decompression or oxygen monitoring functions.
