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. [. . . ] The first dive of the series will be numbered as DIVE 1, the second as DIVE 2, the third as DIVE 3, etc. If you start a new dive in less than 5 minutes at the surface, the dive computer interprets this as a continuation of the previous dive and the dives are considered to be one and the same. The diving display will return, the dive number will remain unchanged, and the dive time will begin where it left off. After 5 minutes on the surface, subsequent dives are by definition repetitive. The dive counter displayed in the Planning Mode will progress to the next higher number if another dive is made. Fig. Pressing the TIME button twice will show the no-flying time, indicated by an airplane symbol. m MAX NO °C DIVE TIME Fig. The Er symbol indicates that you have violated the ceiling for more than three minutes. You must not dive again for at least 48 hours. Dive Attention Symbol Violated Decompression Ceiling NO Do Not Fly Symbol 33 3. 5. 3. Flying After Diving The no-flying time is shown in the center window next to the airplane image. Flying or traveling to a higher altitude should be avoided at any time the computer counts down the no-flying time. You should always activate the dive computer and check that the airplane symbol is not displayed prior to flying. The no-flying time is always at least 12 hours or equivalent to the so-called desaturation time (if longer than 12 hours). In the permanent Error Mode and GAUGE Mode the no-flying time is 48 hours. Flying or traveling to a higher altitude after a dive may significantly increase the risk of decompression sickness. WARNING! YOU ARE ADVISED TO AVOID FLYING ANY TIME THE COMPUTER COUNTS DOWN THE NO-FLYING TIME!Further, the Divers Alert Network (DAN) advises as follows: - A minimum surface interval of 12 hours would be required in order to be reasonably assured a diver will remain symptom free upon ascent to altitude in a commercial jetliner (altitude up to 2400 m [8000 ft]). - Divers who plan to make daily, multiple dives for several days, or make dives that require decompression stops, should take special precautions and wait for an extended interval beyond 12 hours before flight. Further, the Undersea and Hyperbaric Medical Society (UHMS) suggests divers using standard air tanks and exhibiting no symptoms of decompression sickness wait 24 hours after their last dive to fly in an aircraft with cabin pressure up to 2400 m [8000 ft]. The only two exceptions to this recommendation are: - If a diver had less than 2 hours total accumulated dive time in the last 48 hours, then a 12 hour surface interval before flying is recommended. - Following any dive that required a decompression stop, flying should be delayed for at least 24 hours, and if possible, for 48 hours. SUUNTO recommends that flying is avoided until all the DAN and UHMS guidelines and the dive computer wait to fly conditions are satisfied. WARNING! THERE CAN NEVER BE A FLYING AFTER DIVING RULE THAT IS GUARANTEED TO PREVENT DECOMPRESSION SICKNESS COMPLETELY! 34 3. 6. AUDIBLE AND VISUAL ALARMS The dive computer features audible and visual alarms to advise when important limits are approached or to acknowledge preset alarms. C B T m MAX NO DEC TIME A short single beep occurs, when: · · the dive computer is activated when the dive computer automatically returns to the TIME Mode. °C TIME BEE BEE EEP P P B Fig. 3. 31 Preset time alarm is activated. Three single beeps with a two second interval and the backlight activated for 5 seconds occur, when: · the no-decompression dive turns into a decompression dive. [. . . ] Time spent at a decompression stop or range before surfacing, to allow absorbed nitrogen to escape naturally from tissues. On a decompression dive the depth range, between the floor and ceiling, within which a diver must stop for some time during ascent. Decompression range 71 Decompression sickness Any of a variety of maladies resulting either primarily or secondary from the formation of nitrogen bubbles in tissues or body fluids, as a result of inadequately controlled decompression. Dive series A group of repetitive dives between which the dive computer indicates some nitrogen loading is present. Elapsed time between leaving the surface to descend, and returning to the surface at the end of a dive. [. . . ]
