[. . . ] Residual nitrogen, no-decompression limits for the next dive and other data are calculated taking into account the current altitude. As you move across altitude ranks, the watch re-calculates residual nitrogen on the spot. SELECTION OF MEASUREMENT UNITS The measurement units of depth and temperature can be selected from "meters (m) and centigrade (° C)" and "feet (ft) and Fahrenheit (° F)". HOW TO SET THE DEPTH & TEMPERATURE UNITS A Press to show DIVE PLAN display. B Depth unit Altitude rank indicator Altitude rank Indicator 0 1 2 3 Measurement error A Press for 4 to 5 seconds to change over the depth and temperature units. * With each press of the button, the units of depth and temperature change over alternately between "meters and centigrade" and "feet and Fahrenheit". B Nil (Flashing) Altitude above sea level 0 ~ 900 m 0 ~ 3000 ft 600 ~ 1700 1300 ~ 2500 2200 ~ 6000 m m m 2000 ~ 5500 4300 ~ 8200 7200 ~ 19700 ft ft ft 6001 m and higher 19700 ft and higher Note: Once the units of depth and temperature are set in the DIVE PLAN display, those in the DIVE LOG display and the DIVE mode will also be set accordingly. 14 Notes: 1. The altitude range in the above table provides general guideline of altitude only, and the altitude rank indication does not indicate a specific altitude. If the watch senses an altitude change across altitude ranks, the residual nitrogen indicator may appear even while you are on the surface. This is not a malfunction. HOW TO USE DIVE COMPUTER FUNCTIONS English DIVE PLAN FUNCTION WARNING Before using the dive plan function, be sure to check the gas mixture of your scuba tank, set FO2 accordingly and set the unit of depth as required. No-decompression limits corresponding to each of the 14 ranks of depth of water are displayed. Depth rank : In meters : 9 m, 12 m, 15 m, 18 m, 21 m, 24 m, 27 m, 30 m, 33 m, 36 m, 39 m, 42 m, 45 m and 48 m. In feet : 30 ft, 40 ft, 50 ft, 60 ft, 70 ft, 80 ft, 90 ft, 100 ft, 110 ft, 120 ft, 130 ft, 140 ft, 150 ft and 160 ft. No-decompression limits are calculated according to FO2 you have set, current altitude rank and residual nitrogen during surface interval. HOW TO USE THE DIVE PLAN FUNCTION A Press to show DIVE PLAN display. No-decompression limit FO2 you have set * With each press of buttons C and D, the depth rank advances and moves back by one rank, respectively. * As you select a depth rank, the watch calculates and displays a corresponding no-decompression limit. The display cannot be changed over to the DIVE PLAN for 10 minutes after a dive. Please note that it may take some time to calculate nodecompression limits. During surface interval: While the watch counts down the desaturation time during surface interval, surface time and desaturation time are also shown in the DIVE PLAN display. When planning a dive with nitrox: Depending on the FO2 setting, "­ ­" appears in place of nodecompression limit for a depth rank. It indicates that the selected depth rank exceeds the maximum depth to which you can descend with the gas mixture you have set. Depth rank · "9 m" / "30 ft" is displayed first. A C or D Press to select the desired depth rank. C · "+" and "­" appear near buttons C and D, respectively. D 15 English HOW TO USE DIVE COMPUTER FUNCTIONS DIVE FUNCTION The auto switch (water contact sensor) senses water and automatically activates the DIVE FUNCTION, showing the DIVE display. There is no need to change the displays manually. As you descend to 1. 5 m (5 ft) underwater, the watch starts showing the current depth and measuring the diving time. During a dive, the watch automatically measures depth, water temperature and dive time, and provides the information necessary for diving including warnings on hazards. WARNING Before making a dive, be sure to check the function of your watch, following the instructions set forth in "BEFORE DIVING" in "PRECAUTIONS FOR DIVING" on page 4. Also, be sure to set FO2 according to the gas mixture of your scuba tank. Select the measurement units of depth and temperature as you require. They cannot be selected while you are underwater. DISPLAY WHILE DIVING During no-decompression diving Residual nitrogen indicator No-decompression limit Dive time Oxygen limit indicator FO2 you have set C Current depth Current time D Maximum depth Water temperature Partial pressure of oxygen (PO2) D 16 Press to illuminate the display for 2 to 3 seconds. * The illuminating light will not stay lit if the button is kept pressed. C Press and hold to display current time, partial pressure of oxygen (PO2) and data. * The display is illuminated for 2 to 3 seconds. HOW TO USE DIVE COMPUTER FUNCTIONS English After no-decompression limit reaches "0" (during decompression diving): WARNING Do not make a decompression stop at a depth shallower than the decompression stop depth the watch indicates. It is in violation of the decompression stop warning, and the watch will not count down the decompression stop time and total ascent time even if you make a stop during ascent. Even after the watch has given a decompression stop violation warning, it will resume calculation of nodecompression diving if you return to the indicated decompression stop depth and make a decompression stop as indicated by the watch. If you continue ascending and surface, defying the warning, the watch cannot be used for diving for 48 hours. [. . . ] It is so adjusted that it operates with stable accuracy when used on the wrist within a temperature range between 5° C and 35° C (41° F and 95° F). Solution Take the watch to the retailer from whom it was purchased immediately for battery replacement. The number of residual nitrogen indicator bars on the display increased while on the surface. The number of residual nitrogen indicator bars on the display increased during flight. [. . . ]
