WARNING
Always make sure to inspect all functions of the watch prior to each dive to
prevent malfunction of the watch and accidents caused by use of the watch
at improper settings. (Refer to the section entitled, “Cautions Regarding
Use During Diving” (p. 17), for information on the inspection procedure.) In
particular, always make sure to check whether the watch is sufficiently
charged, whether the oxygen concentration (O
2%) is set correctly, and
whether there are warnings being displayed.
WARNING
Diving when using this watch is limited to recreational diving at a water
temperature from +10°C to +40°C (50°F to 104°F).
Do not use this watch for saturation diving using helium gas, diving at a water
temperature outside the above temperature range or high-altitude diving at 3,000 m
(10,000 ft) above sea level or higher since this can prevent the watch from functioning
properly or lead to an accident resulting in danger. In addition, this watch does not
display depth properly when used in water other than seawater (specific gravity of
1.025).
WARNING
In order to ensure safe diving, dive while allowing an adequate margin of
safety relative to the displayed no-decompression limit time.
WARNING
If decompression diving should happen to occur, immediately start to
ascend while observing an ascent rate of no more than 18 m (60 ft)/min.
Since decompression diving is associated with a high risk of decompression sickness,
observe the following matters at all times.
• 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.
• 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.
