Solar cell

The electricity generated by the solar cell of the watch is stored by a rechargeable 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.

•The watch continues to operate, even when it is not exposed to light. Leaving the watch in the dark can cause the battery to run down, which will result in some watch functions to be disabled. If the battery goes dead, you will have to re-configure watch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

Battery charges in the light.

•The actual level at which some functions are disabled depends on the watch model.

•Frequent display illumination can run down the battery quickly and require charging. The following guidelines give an idea of the charging time required to recover from a single illumination operation.

Approximately 5 minutes exposure to bright sunlight coming in through a window Approximately 8 hours exposure to indoor fluorescent lighting

•Be sure to read “Power Supply” (page E-39) for important information you need to know when exposing the watch to bright light.

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-51) for more information.
