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. [. . . ] The segments exceeding the 80% limit start to blink (Fig. 3. 23. ) 33 - the OLF bar graph reaches 100%. The blinking of the segments exceeding 80% will stop, when the OLF is not loading anymore. At that point the PO2 is less than 0. 5 bar. Continuous beeps for 3 minutes occur, when: the set oxygen partial pressure limit is exceeded. The maximum depth is replaced with a current blinking PO2 value. You should immediately ascend above the PO2 depth limit (Fig. 3. 23. ). WARNING! WHEN THE OXYGEN LIMIT FRACTION INDICATES THAT THE MAXIMUM LIMIT IS REACHED, YOU MUST IMMEDIATELY ASCEND UNTIL THE WARNING STOPS BLINKING!Failure to take action to reduce oxygen exposure after the warning is given can rapidly increase the risk of oxygen toxicity and the risk of injury or death. 3. 7. 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. 7. 1. Altitude Adjustment When programming the instrument for the correct altitude, you need to select the correct Altitude Mode according to Table 3. 4. The dive computer will adjust its mathematical model according to the entered altitude mode, giving shorter nodecompression times at higher altitudes (see Section 6. 1. "Operating Principles", Table 6. 1. The entered Altitude Adjustment Mode is indicated by mountain symbols (A0, A1 TABLE 3. 4. ALTITUDE ADJUSTMENT RANGES Altitude mode A0 A1 A2 Symbol on display Altitude range 0 - 300 m [0 - 1000 ft] 300 - 1500 m [1000 - 5000 ft] 1500 - 3000 m [5000 - 10000] = one mountain, or A2 = two mountains). " Personal Adjustments" describes how the Altitude Mode is adjusted. Traveling to a higher elevation can temporarily cause a change in the equilibrium 34 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. 3. 7. 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 ++). [. . . ] OLF Abbreviation for Oxygen Limit Fraction. OTU Abbreviation for Oxygen Tolerance Unit. Oxygen Tolerance Unit Is used to measure the Whole-Body-Toxicity. Dive series 63 Oxygen Limit Fraction A term used by SUUNTO for the values displayed in the Oxygen Toxicity bargraph. The value is either the CNS% or the OTU%. [. . . ]
