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 is used in connection with a procedure or situation that will result in damage to the product. [. . . ] Further, the Undersea and Hyperbaric Medical Society (UHMS) suggests divers using standard air tanks 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: 52 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. 2. 4. HIGH ALTITUDE DIVES AND PERSONAL ADJUSTMENT The dive computer can be adjusted both for diving at altitude and also to increase the conservatism of the mathematical nitrogen model. 3. 2. 4. 1. ALTITUDE ADJUSTMENT When programming the instrument for the correct altitude, you need to select the correct Altitude Mode according to Table 3. 3. The dive computer will adjust its mathematical model according to the entered altitude mode, giving shorter nodecompression times at higher altitudes (see chapter 7. 1. , Table 7. 1. ALTITUDE ADJUSTMENT RANGES $OWLWXGH PRGH $ $ $ 6\PERO RQ GLVSOD\ $OWLWXGH UDQJH P > IW@ P > IW@ P > @ The entered Altitude Adjustment Mode is indicated by mountain symbols (A0, A1 = one mountain, or A2 = two mountains). Also, the maximum altitudes are displayed for each Altitude group (see Table 3. 3. ). describes how the Altitude Mode is adjusted. Traveling to a higher elevation can temporarily cause a change in the equilibrium of dissolved nitrogen in the body. It is recommended that you acclimate to the new altitude by waiting at least three hours before making a dive. 54 3. 2. 4. 2. PERSONAL ADJUSTMENT There are adverse personal factors for DCI which divers can predict in advance and input into the decompression model. Factors that may affect susceptibility to decompression illness vary between divers and also for the same diver from one day to another. The three-step Personal Adjustment Mode is available, if a more conservative dive plan is desired. The personal factors which tend to increase the possibility of DCI include, but are not limited to: cold exposure - water temperature less than 20 °C [68 °F] the diver is below average physical fitness level diver fatigue diver dehydration previous history of DCI stress obesity The Personal Adjustment Mode is indicated by a diver symbol and plus signs (P0 = a diver, P1 = diver +, or P2 = diver ++). describes how the Personal Mode is adjusted. 55 This feature should be used to adjust the computer to be more conservative, according to personal preference, by entering the suitable Personal Adjustment Mode with the help of Table 3. 4. In ideal conditions, retain the default setting, P0. If conditions are more difficult or other mentioned factors which tend to increase the possibility of DCI exist, select P1 or even the most conservative P2. As a result the dive computer adjusts its mathematical model according to the entered Personal Adjustment Mode, giving shorter no-decompression times (see chapter 7. 1. , Table 7. 1.
