Keep the watch exposed to bright light
The electricity generated by the solar cell of the watch is stored by a built-in
Bright Light
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.
Solar cell
You should try to keep the watch outside of your sleeve as much as
possible. Charging is reduced signifi cantly if the face is even only partially
covered.
If the display of the watch is blank...
If the display of the watch is blank, it means that the watch's Power Saving function has turned off the
display to conserve power.
See "Power Saving Function" (page E-50) for more information.
