Permanent Error
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 PO
2 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.
