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 and keep it on hand for later reference when necessary.

Keep the watch exposed to bright light

		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
l	l	l	l	l l	l l l	l	l	it is not exposed to light causes the battery to run down.
								Make sure the watch is exposed to light as much as possible.

Solar cell	• 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 only partially covered.

• 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 cause 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.

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

•Frequent display illumination can quickly run down the battery 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 50 minutes exposure to indoor fluorescent lighting

•Be sure to read “Power Supply” 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” for more information.
