WARNING
In order to ensure safe diving, dive while allowing an adequate margin of safety
relative to the displayed no-decompression limit time.
WARNING
Never dive in a manner that requires a decompression stop (decompression diving).
If decompression diving should happen to occur, immediately start to ascend while
observing an ascent rate of no more than 18 m/min. Make a decompression stop
while ascending in accordance with decompression stop instructions.
When making a decompression stop, never ascend to a depth less than the instructed
depth. In addition, since it is difficult to maintain a constant depth when there are high
waves and so forth, make decompression stops at depths a little deeper than the
instructed depth to prevent decompression sickness.
* A permanent error (ERROR) occurs when continuing to dive while ignoring decompression
stop instructions during the course of decompression diving, and the watch will not switch to
the dive mode for 24 hours after that time.
WARNING
Avoid traveling in an aircraft while the surface mode is activated. Traveling in an
aircraft without allowing sufficient time to rest after diving results in the risk of
decompression sickness. It is recommended to avoid traveling in an aircraft for at
least 24 hours after diving whenever possible even if the surface mode is no longer
displayed. There are no rules for completely preventing decompression sickness
caused by flying in an aircraft after diving.
CAUTION
Skin diving after scuba diving is not recommended. It is recommended to avoid skin
diving for at least two hours after scuba diving and not to exceed a depth of 5 m.
Data Storage
• The various data recorded in the watch may be lost when subjected to incorrect use
or the effects of strong electricity and electrical noise as well as during a malfunction
and repair. Always make sure to keep a separate record of important data recorded
in the watch. Diving data in particular should be transferred to your PC or recorded
in a log book as quickly as possible.

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. This watch cannot be used for decompression diving, saturation
diving using helium gas, diving at high altitudes (300 m 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.
