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.

Keep the watch exposed to bright light

		Bright Light					The electricity generated by the solar cell of the watch is
l						l	stored by a built-in battery. Leaving or using the watch
	l	l l l	l	l l l	l		where it is not exposed to light causes the battery to run
							down. Make sure the watch is exposed to light as much as
Solar cell							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 even 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 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.
