Three classifications are used to separate these references by their order of importance. WARNING CAUTION NOTE is used in connection with a procedure or situation that may result in serious injury or death. is used in connection with a procedure or situation that will result in damage to the product. [. . . ] Current tank pressure is 168bar and remaining air time is 19min. Alternative displays by pressing the UP/DOWN buttons: - Fig. An annotation, Bookmark, is placed in the profile memory during a dive by pressing SELECT button. In addition with the optional wireless transmission enabled: 6. 1. 2. BOOKMARK It is possible to make special marks in the profile memory during a dive. These Bookmarks will be displayed when scrolling the profile memory on the computer display. The Bookmarks will also be shown as annotations in the PC-software, Suun- 55 to Dive Manager. The bookmark logs the depth, time and water temperature as well as compass heading and tank pressure when available. To make a bookmark in the profile memory during a dive press the SELECT button. A brief confirmation will be given (Fig. Pressure has dropped below 50 bar [725 psi]. Pressure display is blinking and there is an audible alarm. When using the optional wireless pressure transmitter the pressure of your scuba cylinder in bars [psi] will be shown digitally in the lower left corner of the alternative display (Fig. Anytime you enter into a dive, the remaining air time calculation begins. After 30 - 60 seconds (sometimes more, depending on your air consumption), the first estimation of remaining air time will be shown in the left center window of the display. The calculation is always based on the actual pressure drop in your cylinder and will automatically adapt to your cylinder size and current air consumption. The change in your air consumption will be based on constant one second interval pressure measurements over 30 - 60 second periods. An increase in air consumption will influence the remaining air time rapidly, while a drop in air consumption will increase the air time slowly. Thus a too optimistic air time estimation, caused by a temporary drop in air consumption, is avoided. 56 The remaining air time calculation includes a 35 bar [500 psi] safety reserve. This means that when the instrument shows the air time to be zero, there is still about 35 bar [500 psi] pressure left in your cylinder depending on your air consumption rate. With a high consumption rate the limit will be close to 50 bar [725 psi] and with a low rate close to 35 bar [500 psi]. Filling your BC will affect the air time calculation, due to the temporary increase in air consumption. A change of temperature will affect the cylinder pressure and consequently the air time calculation. Low Air Pressure Warnings The dive computer will warn you with three audible double beeps and a blinking pressure display when the cylinder pressure reaches 50 bar [725 psi] (Fig. Three double beeps are also heard when the cylinder pressure goes down to the user selected alarm pressure and when the remaining air time reaches zero. Fig. [. . . ] After a change in ambient pressure, the amount of time required for the partial pressure of nitrogen in a theoretical compartment to go half-way from its previous value to saturation at the new ambient pressure. Dive time P EAD EAN Enriched Air Nitrox Equivalent Air Depth Floor Half-time 112 HP Multi-level dive Abbreviation for high pressure (= cylinder pressure). A single or repetitive dive that includes time spent at various depths and whose no-decompression limits are therefore not determined solely by the maximum depth attained. In sports diving refers to any mix with a higher fraction of oxygen than standard air. United States National Oceanic and Atmospheric Administration. [. . . ]
