bright light.

Leave the watch under
fluorescent lighting, near a
window, etc.
• When wearing the watch, try to keep your sleeve from blocking its
face (solar cell).
Charging efficiency is reduced
significantly even if the face of the
watch is covered only partially by
your sleeve.
Keep your watch exposed to light!
