Warning!
•The measurement functions built into this watch are not intended for
taking measurements that require professional or industrial precision.

Keep the watch exposed to bright light
The electricity generated by the solar cell of the
watch is stored by a built-in battery. Leaving or
using the watch where it is not exposed to light
causes the battery to run down. Make sure the
watch is exposed to light as much as possible.
•When you are not wearing the watch on your
wrist, position the face so it is pointed at a
source of bright light.
•You should try to keep the watch outside of
your sleeve as much as possible. Charging is
reduced significantly if the face is covered only
partially.
