[. . . ] These bookmarks are displayed when scrolling the profile memory on the display. The bookmarks will also be shown as annotations in the downloadable Suunto Dive Manager PC software. The bookmark logs the depth, time, and water temperature, as well as compass heading (if the compass has been enabled) 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. A BOOKMARK IS PLACED IN THE PROFILE MEMORY DURING A DIVE BY PRESSING THE SELECT BUTTON. 6. 1. 3. Tank pressure data The pressure of your scuba cylinder in bars (or psi) is shown digitally in the lower left corner of the alternative display. 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. In this way, an over optimistic air time estimation, caused by a temporary drop in air consumption, is avoided. 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 of pressure left in your cylinder, depending on your air consumption rate. With a high consumption rate, the limit will be closer to 50 bar/725 psi and with a low rate closer to 35 bar/500 psi. 30 NOTE NOTE Filling your BC affects 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. 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. Ascent rate indicator The ascent rate is shown graphically along the right hand side. When the maximum allowed ascent rate is exceeded, the lower segments start to blink with the top segment staying solid, indicating that the maximum ascent rate has been exceeded continuously or that the current ascent rate is significantly above the allowed rate. ACTIVATED BACKLIGHT, ALARM AND A BLINKING ASCENT RATE BAR GRAPH INDICATE YOU ARE ASCENDING FASTER THAN 10 M/MIN. YOU ARE ADVISED TO MAKE A MANDATORY SAFETY STOP WHEN YOU REACH A DEPTH OF 6 M. NORMAL ASCENT RATE. WARNING DO NOT EXCEED THE MAXIMUM ASCENT RATE!You should always make the Mandatory and Recommended Safety Stops after you have exceeded the maximum recommended ascent rate. If this Mandatory Safety Stop is not completed, the decompression model will penalize your next dive(s). Continuous ascent rate violations will result in Mandatory Safety Stops. [. . . ] Standard mixes are EAN32 (NOAA Nitrox I = NN I) and EAN36 (NOAA Nitrox II = NN II). The deepest depth during a decompression stop dive at which decompression takes place. 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. 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. [. . . ]
