PO2 is low. Descend or switch to higher O2 gas. | Your PO2 value is below 0.18 bar. | If you are within the first two minutes of your dive, your PO2 value flashes yellow. Otherwise, your PO2 value flashes red. The alert appears every 30 seconds until you descend to a safe level or switch gases. |
Approaching Deco Stop | You are within one stop interval (3 m or 9.8 ft.) of the decompression stop depth. | None |
Descend below deco ceiling. | You are more than 0.6 m (2 ft.) above the decompression ceiling. | The current depth and stop depth flash red. If you remain above the decompression ceiling for more than three minutes, the decompression lockout feature goes into effect. |

CNS toxicity at 80%. | Your central nervous system (CNS) oxygen toxicity is at 80% of the safe limit. | The alert appears during a dive and on the dive pre-check screen for your next dive. |
CNS toxicity at %1%. End your dive now. | Your CNS oxygen toxicity is too high. During a dive, "%1" is replaced with your current CNS percentage. | The alert appears every two minutes until you end the dive. |
250 OTU accumulated. | Your oxygen toxicity units (OTU) are at 80% of the safe limit (250 units). | None |
%1 OTU accumulated. End your dive now. | Your oxygen toxicity units are above the safe limit. During a dive, "%1" is replaced with the number of units accumulated. | The alert appears every two minutes until you end the dive. |
NDL exceeded. Decompression now required. | You have exceeded your no decompression limit (NDL) time. | None |
Approaching NDL | You are at 80% of your tissue load. | None |
Battery is low. | Less than 20% battery power remains. | The alert appears when the device is below 20% battery power and on the dive pre-check screen. |
Battery critically low. End your dive now. | Less than 10% battery power remains. | The alert appears when the device is below 10% battery power and on the dive pre-check screen. |
