Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to read this manual carefully.

Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss suffered by you or any third party arising through the use of this product or its malfunction.

Keep the watch exposed to bright light

Bright Light

Solar cell

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.

ξWhen you are not wearing the watch on your wrist, position the face so it is pointed at a source of bright light.

ξYou should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly if the face is even only partially covered.

ξThe 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.

Rechargeable battery

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

ξFrequent 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 about 8 hours exposure to indoor fluorescent lighting

ξBe sure to read “Power Supply” (page E-36) for important information you need to know when exposing the watch to bright light.
