[. . . ] NOTE With Deep Stops on, the Recommended Safety Stops will still be activated at the end of the dive. 25 6. DIVING This section contains instructions on how to operate the dive computer and interpret its displays. Each display shows only the data relevant to that specific diving mode. Diving in AIR mode (DIVEair) In this section, we look at how to make the most of the dive computer when diving with standard air. Accessing DIVE mode. DIVE HAS JUST BEGUN AND AVAILABLE NO-DECOMPRESSION TIME IS OVER 99 MINUTES SO NO VALUE IS DISPLAYED. NOTE The dive computer will remain in the Surface mode at depths less than 1. 2 m/4 ft. At depths greater than 1. 2 m/4 ft the instrument will go into the DIVE mode automatically. However, it is recommended that you activate the DIVE Mode manually in order to perform the necessary dive pre-checks. 6. 1. 1. Basic dive data During a No-decompression dive, the following information is displayed: · your present depth in meters/feet · the available no-decompression time in minutes as NO DEC TIME · the ascent rate presented as a bar graph on the right side · the Diver Attention Symbol if surface interval should be prolonged (see Table 7. 1, Alarms) DIVE DISPLAY - PRESENT DEPTH IS 15 M, NO-DECOMPRESSION STOP TIME LIMIT IS 38 MIN. ELAPSED DIVE TIME IS 13 MIN. Alternative displays, by pressing the UP/DOWN buttons, show: · the elapsed dive time in minutes, shown as DIVE TIME · the water temperature in °C/°F · the maximum depth during this dive in meters/feet, indicated as MAX · the current time, shown as TIME DOWN BUTTON TOGGLES BETWEEN MAXIMUM DEPTH AND CURRENT TIME. 26 UP BUTTON TOGGLES BETWEEN DIVE TIME AND WATER TEMPERATURE. 6. 1. 2. Bookmark It is possible to record bookmarks in the profile memory during a dive. 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). 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. Ascent rate indicator The ascent rate is show 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. When Recommended Deep Stop is enabled, the length is indicated in seconds. 6. 1. 4. [. . . ] 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. [. . . ]
