Cautions Regarding Use During Diving
WARNING
This watch cannot be used as a primary instrument for diving.
When using the watch during diving, always make sure to receive the proper
diving instruction and training and use the watch while obeying all rules.
• Inspect the watch to make sure that all functions operate properly before diving.
• It is recommended to only use this watch for recreational diving down to a depth of about
18 m (60 ft). Do not attempt to dive below the limit depth of 40 m (131 ft) during
recreational diving.
• Always make sure to allow an ample margin for no-decompression time.
• Perform adequate safety stops and decompression stops. Even in the case of no-
decompression diving, always make a safety stop at 5 m (15 ft) to ensure safety. In
addition, in the case the decompression stop display appears, try to stop for a period
longer than that indicated on the display.
• Allow for a sufficient rest period after diving in accordance with safety rules. Boarding an
airplane or moving to a high altitude without allowing for a sufficient rest period after
diving results in the risk of decompression sickness.
PROHIBITED
Prohibited Use During Diving
Never attempt to use this watch for diving under the following circumstances.
• When diving is prohibited in the system monitor mode:
··· The watch will not switch to the dive mode when [ ] has changed to NG.
• When the watch has stopped running or an error has occurred (be careful not to bump
the watch against hard objects such as equipment or rocks when diving).
• When measuring depth outside the guaranteed water temperature range or at high
altitudes:
··· The temperature range in which the water depth measurement accuracy of this watch
is guaranteed is +10 to +40°C (50°F to 104°F).
··· This watch is not compatible with diving at high altitudes. Never use this watch when
diving at high altitudes (300 m (1000 ft) or more above sea level).
• When engaged in dangerous behavior or when a situation is judged to be dangerous:
··· This watch is not built to function as a preventive or emergency instrument such as for
use during marine accidents.
• When using in a helium gas atmosphere (saturation diving, etc.):
··· Use under these conditions can cause a malfunction or damage to the watch.
• Use for nitrox diving:
··· This watch cannot be used for diving using a mixed gas other than that of air tanks for
ordinary air diving.
WARNING
Cautions Regarding Use During Diving
• Sufficiently charge the watch and confirm that the watch is reliably charged and that the
watch can be used for diving by referring to the system monitor mode. If the watch is not
sufficiently charged, the watch will not switch to the dive mode even if diving is started.
In addition, try to start a dive after first sufficiently charging the watch before diving to
avoid having the watch become insufficiently charged while diving.
