● When the no-decompression limit reaches “0” while
diving, all the residual nitrogen indicators are displayed
to indicate that the watch has shifted to decompression
diving mode.
● After you make decompression stops as indicated by the
watch, it will resume calculation of no-decompression
diving.
★
★ Total ascent time refers to the minimum time required to
stay underwater before surfacing, including the
decompression stop time at the indicated decompression
stop depths.
● Do not make a decompression stop at a depth
shallower than the decompression stop depth the
watch indicates. It is in violation of the decompression
stop warning, and the watch will not count down the
decompression stop time and total ascent time even
if you make a stop during ascent.
● Even after the watch has given a decompression stop
violation warning, it will resume calculation of no-
decompression diving if you return to the indicated
decompression stop depth and make a decompression
stop as indicated by the watch. If you continue
ascending and surface, defying the warning, the
watch cannot be used for diving for 48 hours. During
that time period, the watch is not set to calculate
decompression diving, and only the surface interval
and dive log displays are shown. If the aquatic
environment permits, it is recommended that you
make a decompression stop at a depth 1 to 2 m (3 to
7 ft) deeper than the indicated decompression stop
depth. In that case, take care that you should stay at
the depth for a longer time period than the
decompression stop time that the watch indicates.
