•
Ensure the buttons and battery compartment are secured
and intact before exposing the watch to excessive
water.
•
Avoid pressing the buttons while in the water or during
heavy rainstorms, as this may cause water to enter the
watch, leading to malfunction.
NOTE
Even if both the watch and the chest belt are
water resistant, as radio signals do not carry in water, signal
transmission between the watch and chest belt will still be
impossible in water.
