WARNING
• Diving is a potentially dangerous sport. When using this watch for diving,
make sure to have a correct understanding of this watch as described in
this manual and strictly adhere to the procedures for its operation. The
watch may not function properly if handled in a manner not described in
this manual.
• This watch should not be used as a primary instrument for diving.
• Diving while using this watch is limited to recreational diving (no
decompression diving) in salt water at a water temperature of +10°C to
+40°C (50°F to 104°F). This watch cannot be used for decompression
diving, saturation diving using helium gas, diving at high altitudes (300 m
(1000 ft) or more above sea level) or diving outside the above temperature
range. In addition, this watch can not be used for nitrox diving (diving using
a mixed gas of oxygen and nitrogen in which the oxygen concentration is
richer than air tanks used for ordinary diving).
• Although this watch provides data for decompression diving in cases of
emergency, never attempt to use this watch for decompression diving since
this is potentially dangerous.
In addition, the watch does not display depth correctly when used in water
other than salt water (specific gravity: 1.025).
• Even recreational diving can be dangerous. Users are requested to obtain
the proper scuba diving training from a qualified instructor, acquire the
necessary experience and skills for safe diving and completely master the
handling and operation of this watch before using this watch as an auxiliary
instrument for diving. Insufficient or improper training may cause errors to
be made during diving that may lead to serious injury or death.
• Sudden atmospheric fluctuations and changes in water temperature may
have an effect on the display and performance of the watch. Since this
watch is not intended to be used as a specialized instrument, and is only
intended to display information to serve as a reference for minimizing
decompression sickness and other dangers, it is not designed to guarantee
the safety of the user. Always make sure to use this watch in combination
with other instruments (such as a diving table, residual pressure gauge and
water depth gauge). Never use it as a primary instrument for diving.
• This watch is designed on the premise of being used only by one person.
Never lend to or share this watch with another person while resting on the
surface (while the surface mode is activated). In addition, do not use the
data displayed by the watch as diver data for persons other than the user.
