[. . . ] EN SUUNTO VYTEC DS INSTRUCTION MANUAL QUICK REFERENCE GUIDE DEFINITION OF WARNINGS, CAUTIONS AND NOTES Throughout this manual, special references are made when deemed important. Three classifications are used to separate these references by their order of importance. WARNING - is used in connection with a procedure or situation that may result in serious injury or death. CAUTION NOTE - is used in connection with a procedure or situation that will result in damage to the product. [. . . ] The no-flying time is always at least 12 hours or equivalent to the socalled desaturation time (if longer than 12 hours). In the permanent Error mode and Gauge mode the no-flying time is 48 hours. Divers Alert Network (DAN) recommends the following on no-flying times: · 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 cylinders and exhibiting no symptoms of decompression illness 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: 37 · · · 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. 3. 7. AUDIBLE AND VISUAL ALARMS The dive computer features audible and visual alarms to advise when important limits are approached or to acknowledge preset alarms. A short single beep occurs, when: · the dive computer is activated. · when the dive computer automatically returns to the TIME mode. Three double beeps occur, when: · the cylinder pressure reaches 50 bar [725 psi]. The cylinder pressure display will start to blink (Fig. · the cylinder pressure reaches the selected alarm pressure. · the calculated remaining air time reaches zero. 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 stop dive. An arrow pointing upwards and the blinking ascent warning ASC TIME will appear (Fig. · Gas change is prompted Continuous beeps and the backlight activated for 5 seconds occur, when: · the maximum allowed ascent rate, 10 m/min [33 ft/min], is exceeded. SLOW and STOP warnings will appear (Fig. · the Mandatory Safety Stop ceiling is exceeded. A downward pointing arrow will appear (Fig. · the decompression ceiling depth is exceeded. [. . . ] The deepest depth during a decompression stop dive at which decompression takes place. Decompression range Decompression illness Dive series Dive time DP EAD EAN Enriched Air Nitrox Equivalent Air Depth Floor 76 Half-time 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. 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. [. . . ]
