CAUTION
• The table of no decompression limits is provided for one-time diving.
• Since the no decompression limits differ depending on the diver's physical
condition and varies among individuals, use this table as a guideline only.
• In case of diving that requires the diver to take a rest for decompression
before ascending to the surface, always follow a reliable manual exclusively
compiled for diving.

D. No Decompression Limits
The range within which the diver can rise to the surface without rest for
decompression is determined by the depth and elapsed time of the dive. The
ranges are called "No Decompression Limits".
A table of "No Decompression Limits" compiled according to the U.S. Navy
Diving Manual (1993 edition) is printed on the watchband of this watch (there
are some models that do not have this table on the watchband).
Example: Read the
table as follows.
In case the maximum
dive depth is 21m
and the elapsed time
is 50 minutes or
shorter, the diver is
not required to take a
rest for decompres-
sion while ascending
to the surface.
