After 5 minutes the ceiling for on the surface, subsequent dives are, by defimore than three minutes. You must not dive again nition, repetitive. The dive counter displayed °C DIVE TIME for at least 48 hours. 36 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. The airplane symbol is not shown on the stand-by display. You should always activate the dive computer and check that the airplane symbol is not displayed prior to flying. The no-flying time is always at least 12 hours or equivalent to the socalled desaturation time (if longer than 12 hours). You should immediately descend to, or below, the ceiling. The instrument will otherwise enter a permanent Error Mode within three minutes, indicated by a permanent Er (Fig. 3. 19. ). 38 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. · the dive time blinks for one minute, if no button is pressed. · The preset alarm time is reached · 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. OXYGEN ALARMS IN NITROX MODE Three double beeps and the backlight activated for 5 seconds occur, when: · the OLF bar graph reaches 80%.

Standard mixes are EAN32 (NOAA Nitrox I = NN I) and EAN36 (NOAA Nitrox II = NN II). Nitrogen partial pressure equivalent table. [. . . ]
