If hazardous diving or ascending is continued even after the permanent error warning function has been activated, a permanent error results, "ERROR" appears on the display and the entire display flashes.

When a permanent error has occurred, the next dive cannot be made for 24 hours. (The water depth measurement function does not operate

for 24 hours. In addition, "ERROR" is displayed when the watch is

switched to the dive plan mode, and the no-decompression limit time is

 

not displayed.)

PO2 Limit Warning

PO2 flashes to warn that the PO2 limit is approaching at the depth where PO2 (body partial pressure of oxygen) reaches 1.4 during diving in the NITROX setting.

The alarm stops when you ascend to a shallow depth and PO2 falls below 1.4.

PO2 limit Error

An alarm sounds for 15 seconds every minute in addition to PO2 flashing display when PO2 exceeds the limit of 1.6 as a result of not ascending to a shallow depth even after the PO2 limit warning has been activated.

The error is canceled and the display returns to the PO2 limit warning display when you ascend to a shallow depth and PO2 falls below 1.6.

Oxygen Toxication Time Warning

When the amount of time remaining until the oxygen toxication time (OTT) decreases to less than 10 minutes during diving in the NITROX setting, the display in the upper right corner of the display changes from no-decompression limit time (NDL) to remaining OTT time (flashing). In the case of decompression diving, remaining OTT time flashes instead of the total ascent time in the upper right corner of the display.

The warning stops if you ascend to a shallow depth and the remaining OTT time returns to 10 minutes or more.

Oxygen Toxication Time Error

If the remaining OTT time reaches 0 minutes as a result of not ascending to a shallow depth even after the oxygen toxication time warning has been activated, an oxygen toxication error occurs, and in addition to “0’ ” flashing for the remaining OTT time, the alarm sounds for 15 seconds every minute.

The error is canceled and the display returns to the oxygen toxication time warning state when you ascend to a shallow depth and the remaining OTT time increases.
