Residual oxygen level warning
CAUTION !!
During a NITROX dive, the effects of oxygen on the body varies according to the maximum
dive depth based on the oxygen mix ratio setting and the amount of dive time spent within the
maximum depth range.
Accordingly, when a partial pressure warning or residual oxygen level warning occurs, the
diver should rapidly move to a safe dive depth.
Remaining at the same depth after either of these warnings occurs is hazardous and definitely
should be avoided.
• Decompression stop violation warning
This display appears and an alarm is sounded (for three seconds) if the current depth is
shallower than the decompression stop depth.
This warning stops when the current depth is again deeper than the decompression
stop depth.
The warning continues if the current depth remains shallower than the decompression
stop depth. Five minutes after surfacing, this warning automatically stops and the
computer is not usable.
After 48 hours, the computer automatically switches to
surface mode .
This warning is recorded in the dive log .
CAUTION !!
Be sure to perform the decompression stops at the indicated depths.
Definitely avoid ascending to depths that are less than the indicated depths.
If underwater conditions prevent this, perform decompression stops at depths between 3 and 7
feet (1 and 2 meters).
The decompression stop times are longer at these shallower depths.
If a decompression stop violation warning is displayed, remember that the decompression stop
times and total ascent time are to be used as a
basic guide .
