The
IQ-600
is designed for use by divers breathing either
normal compressed air or Enriched Air Nitrox (EANx)
mixtures whose fraction of oxygen (FO
2
) falls within a
range of from 22 to 50 percent.
Although the
IQ-600
is capable of calculating decompression
stop requirements, this ability is provided as a safety feature
only, should recreational divers accidentally exceed the
No-Decompression Limits (NDLs). Dives requiring man-
datory stage decompression carry substantially greater risk
than dives made well within no-decompression limits. Divers
should not use the
IQ-600
to plan or execute dives that
will intentionally exceed no-decompression limits.
The
IQ-600
is designed to be used by only one diver at a
time. Divers should not share a single
IQ-600
—or any other
dive computer—on the same dive. Additionally, no diver
should lend his or her
IQ-600
to anyone else until it calcu-
lates that no measurable residual nitrogen remains after
previous dives, and displays neither the “Desaturation
Time” nor “No Fly” indicators while in Surface Mode.
Further, no diver should use his or her
IQ-600
for repetitive
dives—unless that same
IQ-600
has accompanied him or her
on all previous dives in the same repetitive dive series.
