NiTek X Dive Computer User Manual v1.1 6
Warnings
This information has been developed for your safety. Please read and
understand this manual completely before using your NiTek X dive
computer.
Important safety information:
• Before using your NiTek X, it is extremely important that you read
the following points—as well as similar warning and caution
notices that appear throughout this manual. Failure to do so could
result in damage to or loss of equipment, serious personal injury,
or death.
• The NiTek X is designed for use by certified divers who have
maintained a sufficient level of knowledge and skill proficiency
through a combination of formal training, ongoing study, and
experience. It is not intended for use by persons who lack these
qualifications and thus, may not be able to identify, assess, and
manage the risks scuba diving entails. Use of the NiTek X in
conjunction with Enriched Air Nitrox (EANx) or Trimix requires
that divers be trained and certified for Nitrox or Trimix diving.
• The NiTek X is not intended for use by commercial or military
divers whose activities may take them beyond the commonly
accepted depth limits for recreational or technical diving.
• Although the NiTek X is capable of calculating decompression
stop requirements, users must remember that dives requiring
mandatory stage decompression carry substantially greater risk
than dives made well within no-decompression limits.
• The NiTek X is designed for use by one diver at a time. Divers
should not share a single NiTek X—or any other dive computer—
on the same dive. Additionally, no diver should lend their NiTek X
to anyone else until it calculates that no measurable residual
nitrogen remains after previous dives and no longer displays the
“desaturation time” indicator while in time mode. Further, no diver
should use their NiTek X for repetitive dives—unless that same
properly functioning NiTek X has accompanied them on all
previous dives in the same repetitive dive series and is thus,
accurately monitoring the diver’s total exposure to oxygen, helium,
and nitrogen.
• Neither the NiTek X—nor any other dive computer—physically
measures the amount of nitrogen present in body tissues or the rate
at which nitrogen is being absorbed or released. The NiTek X
monitors depth and time, and uses this data to work a mathematical
formula designed to emulate how individuals in good general
health and whose physical characteristics do not place them among
