Cautions Regarding Use of this Watch
DANGER
Do not use this watch during decompression diving, especially during
NITROX diving.
Although this watch will provide data on decompression diving in an emergency,
using this watch for decompression diving entails risks. Since decompression diving
during NITROX diving in particular is very dangerous, never use this watch under
these conditions. Decompression diving during NITROX diving can lead to an
accident causing death or serious injury. (The DCIEM algorithm generates a
particularly hard error in the case of decompression diving during NITROX diving.)
DANGER
Never loan or share the watch with another person when resting on the
surface (while the watch is operating in the surface mode). In addition, do
not use the data displayed by the watch as the data for a person other than
the user.
This watch is designed on the premise of use by a single user.
Since calculations made by the dive computer based on previous diving are continued
to be used during operation in the surface mode, use of the watch by another person
can prevent the dive computer from making calculations suitable for the user,
resulting in the risk of an accident causing death or serious injury.
DANGER
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.
WARNING
In the case of using this watch for diving, always make sure to also use
other backup equipment (including a DCIEM dive table, divers watch,
residual pressure gauge and water depth gauge).
Sudden fluctuations in the atmosphere and changes in water temperature may have
an effect on the display and performance of the watch. Always make sure to use this
watch in combination with other backup instruments in case the watch should happen
to malfunction. The dive computer functions of this watch are not intended to
completely protect you from decompression sickness and oxygen toxication. Since
the watch is only intended to display information to serve as a reference for
minimizing the risk of decompression sickness and so forth, it is not intended to
completely ensure the safety of the user.
