[. . . ] In the Gauge mode the present depth, maximum depth, dive time, cylinder pressure, remaining air time and ascent rate indicator are displayed during the dive (Fig. In addition, temperature and current time are shown in the alternative display. If you dive with the Gauge mode, it is not possible to change between the modes within 48 hours. m MAX AIR TIME bar DIVE TIME Fig. 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. 28. ): · · · · · · · · maximum depth of last dive in meters [ft] present depth in meters [ft] no-flying warning indicated by an airplane icon Altitude Adjustment setting Personal Adjustment setting Diver attention symbol indicates if you should prolong your surface interval time STOP label for 5 min, if the Mandatory Safety Stop was violated Er, if the decompression ceiling was violated (= Error Mode) (Fig. 3. 31. ) Cylinder pressure in bars [psi] dive time of last dive in minutes, shown as DIVE TIME. NO bar DIVE TIME Fig. You have surfaced from a 18 minute dive, which maximum depth was 20. 0 m [66 ft]. Airplane symbol indicates that you should not fly and diver attention symbol indicates that you should prolong your surface interval time because of excess micro-bubbles. m MAX NO SURF · · TIME °C TIME Or when the TIME button is pressed once or twice: Fig 3. 29. Pressing TIME button once will show surface time display. · · · · 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 interval (Fig. 3. 29. ) the desaturation/no-flying time in hours and minutes is shown next to the airplane in the center window of the display (Fig. 3. 30. ). 32 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. NO m MAX °C TIME 3. 6. 2. when the dive computer automatically returns to the TIME mode. Three double beeps occur, when: · · · the cylinder pressure reaches 50 bar [725 psi]. 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. 3. 16. ). Continuous beeps and the backlight activated for 5 seconds occur, when: · · · the maximum allowed ascent rate, 10 m/min [33 ft/min], is exceeded. The instrument will otherwise enter a permanent Error Mode within three minutes, indicated by a permanent Er (Fig. 3. 19. ). 35 You are able to preset alarms before the actual dive. The user programmable alarms can be set for maximum depth, dive time and time. The alarms activate when: · The preset maximum depth is reached - continuous beep series for 24 seconds or until any button is pressed. - the maximum depth blinks as long as the present depth value exceeds the adjusted value. The preset dive time is reached - continuous beep series for 24 seconds or until any button is pressed. - continuous beep series for 24 seconds or until any button is pressed. [. . . ] CNS% Compartment DAN DCI Decompression Central Nervous System toxicity limit fraction. Time spent at a decompression stop or range before surfacing, to allow absorbed nitrogen to escape naturally from tissues. Altitude dive Ascent rate ASC RATE Ascent time ASC TIME Ceiling Ceiling Zone CNS Central Nervous System Toxicity Decompression range On a decompression stop dive the depth range, between the floor and ceiling, within which a diver must stop for some time during ascent. Decompression illness 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. 68 Dive series A group of repetitive dives between which the dive computer indicates some nitrogen loading is present.
