WARNING
Since the depth meter function of this watch is not approved as an official depth
gauge, be sure to use this function as an auxiliary means to know the
approximate depth.
Diving is a sport that involves risk. Before using this watch while diving, be sure
to receive diving instruction and training from a qualified instructor to acquire
the experience and skills that are required for safe diving. Always observe the
applicable rules.
• Diving with this watch must be limited to recreational diving (diving without
decompression). Do not use this watch for decompression diving, saturated diving
or diving in a high altitude. The depth meter function of this watch works normally in
seawater with temperatures of +10°C to +40°C (50°F to 104°F), however, depth
indication is incorrect in water other than seawater (specific gravity: 1.025).
• Rapid and sharp change of the atmosphere and/or seawater temperature
occasionally affects the indication and performance of the watch. Therefore, it is
recommended that this watch be used together with another depth gauge. Read the
indication of this watch as a rough guideline.
• Even recreational diving involves many risks. Before using this watch as an
auxiliary instrument for diving, be sure you receive right training in scuba diving by a
qualified instructor in order to acquire experience and technique necessary for safe
diving as well as to master the proper way to handle and operate this watch.
