[. . . ] 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. 27): · · · · · · · · MAX °C DIVE TIME Fig. You have surfaced from a 18 minute dive, which maximum depth was 20. 0 m [66 ft]. The airplane symbol indicates that you should not fly and the dive attention symbol indicates that you should prolong your surface interval time. m NO SURF TIME · TIME °C · the maximum depth in meters [ft] the present depth in meters [ft] the no-flying warning indicated by an airplane icon the Altitude Adjustment setting the Personal Adjustment setting the dive attention symbol indicates that you should prolong your surface interval time the STOP label for 5 min, if the Mandatory Safety Stop was violated Er in the center window, if the decompression ceiling was violated (= Error Mode) (Fig. 3. 30) the current temperature with °C for Centigrade [or °F for Fahrenheit] the dive time in minutes, i. e. the total duration of the most recent dive, shown as DIVE TIME. Fig 3. 28 Surface interval, Surface time display. Pressing the TIME button will show the surface time display. Or when the TIME button is pressed once or twice: · · the current time, shown as TIME instead of the DIVE TIME the surface time in hours and minutes (separated by a colon), telling the duration of the present surface interval (Fig. 3. 28) the no-flying time in hours and minutes is shown next to the airplane in the center window of the display (Fig. 3. 29). · 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 (instead of the CBT). m MAX NO · °C TIME 3. 5. 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 in less than 5 minutes at the surface, the dive computer interprets this as a continuation of the previous dive and the dives are considered to be one and the same. 3. 32 Preset dive time alarm is activated. · BEE P BEE EEP P · B m MAX NO DEC TIME C B T °C DIVE TIME Fig. 3. 33 Preset maximum depth alarm is activated. 35 You are able to set alarms before the actual dive. The preset user programmable alarms can be set for time, dive time and maximum depth. The alarms activate when: · The preset alarm time is reached (Fig. 3. 31) - the current time is shown - continuous beep series for 24 seconds or until any button is pressed - the current time blinks for one minute, if no button is pressed. 3. 32) - continuous beep series for 24 seconds or until any button is pressed - the dive time blinks for one minute, if no button is pressed. 3. 33) - 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. · · OXYGEN WARNINGS IN THE NITROX MODE Three double beeps and the backlight for 5 seconds activate when: the OLF bar graph reaches 80%. The blinking of the segments exceeding 80% will stop, when the OLF is not loading anymore. Continuous beeps for 3 minutes and the backlight for 5 seconds, occur when: · the set oxygen partial pressure and equivalent depth limit is exceeded. · 36 WARNING! WHEN THE OXYGEN EXPOSURE WARNING (OLF) 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. WARNING! CASIO STRONGLY RECOMMENDS THAT SPORT DIVERS LIMIT THEIR MAXIMUM DEPTH TO 40 M [130 FT] OR TO THE DEPTH CALCULATED BY THE COMPUTER BASED ON THE ENTERED O2 AND PO2 OF 1. 4 BAR SETTINGS.
