User manual SUUNTO VYTEC POCKET 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. [. . . ] When the PLAN button is pressed during the dive: A special mark, bookmark is written in the profile memory. The Dive Timer shown in the center window is stopped, reset and started again. 34 Tank pressure and ascent rate indicator are also displayed during the dive (Fig. Remaining Air Time, temperature and current time are shown in the alternative display when the TIME button is pressed. If you dive with the Gauge mode, it is not possible to change between the modes within 48 hours. bar m MAX DIVE TIME 3. 6. Surface Interval An ascent to any depth shallower than 1. 2 m [4 ft] will cause the DIVING display to be replaced by the SURFACE display, giving the following information (Fig. 3. 29. ): maximum depth of last dive in meters [ft] present depth in meters [ft] no-flying warning indicated by an airplane icon (Table 3. 3) Altitude Adjustment setting Personal Adjustment setting Diver attention symbol indicates attenuated RGBM model has been set Flashing Diver attention symbol indicates surface interval time should be prolonged (Table 3. 3) STOP label for 5 min, if the Mandatory Safety Stop was violated Er, if the decompression ceiling was violated (= Error Mode) (Fig. 3. 32, Table 3. 3) Cylinder pressure in bars [psi] (if on, if off temperature is shown) dive time of last dive in minutes, shown as DIVE TIME. Fig. Current dive time is 30 minutes 21 seconds. m MAX NO bar DIVE TIME Fig. You have surfaced from a 18 minute dive, which maximum depth was 20. 0 m [66 ft]. The present depth is 0. 0 m [0 ft]. Airplane symbol indicates that you should not fly and blinking Diver Attention Symbol indicates that you should prolong your surface interval time because of excess micro-bubbles. 35 Or when the TIME button is pressed once or twice: the current time, shown as TIME instead of the DIVE TIME the current temperature with °C for Centigrade [or °F for Fahrenheit] the surface time in hours and minutes (separated by a colon), telling the duration of the present surface Fig 3. 30. Pressing the desaturation/no-flying time in TIME button once will show hours and minutes is shown next to surface time display. 3. 31. ). m MAX NO SURF TIME °C TIME m MAX NO °C TIME Fig. Pressing TIME button twice will show no-flying time, indicated by an airplane symbol. If set to Nitrox mode, the following information will also be shown: the oxygen percentage labeled with O2% is shown on the left side of the center window the current oxygen toxicity exposure shown with an Oxygen Limit Fraction (OLF) bar graph along the left side of the display. 3. 6. 2. Dive Numbering Several repetitive dives are considered to belong to the same repetitive dive series when the dive computer has not counted the no-flying time to zero. 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 with less than 5 minutes of surface interval time, the dive computer interprets this as a continuation of the previous dive and the dives are considered to be 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. Er symbol indicates that you have violated the ceiling for more than three minutes. You must not dive again for at least 48 hours. 36 displayed in the Planning Mode will increment to the next higher number if another dive is made. TABLE 3. 3. Flying After Diving The no-flying time is shown in the center window next to the airplane image. Flying or travelling to a higher altitude should be avoided at any time the computer counts down the no-flying time. [. . . ] Any of a variety of maladies resulting either directly or indirectly from the formation of nitrogen bubbles in tissues or body fluids, as a result of inadequately controlled decompression. 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. Delta P, describing the Cylinder Pressure drop during the dive; difference in cylinder pressure between beginning and end of dive. [. . . ]
