CAUTION
• When diving, obey the rules of the buddy system every time. (Buddy system means
that two divers pair with each other for safe diving.)
• For safety, it is advised that you enjoy sports diving in the depths around 20 m (60
ft).
• Before diving with this watch, fully charge the watch without fail. When the watch is
not sufficiently charged (the function hand points at "NG"), the depth meter function
cannot be used.
If charge of the watch becomes low considerably during diving, the depth meter
function to measure depth is discontinued.
• After diving, take a good rest following safety rules. If you take a plane or move to a
high place without a sufficient rest after diving, you may suffer from decompression
sickness (caisson disease).
