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.

•Be sure to keep all user documentation handy for future reference.

•This watch does not have a city code that corresponds to the UTC offset of –3.5 hours. Because of this, the radio-controlled atomic timekeeping function will not display the correct time for Newfoundland, Canada.

•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.

Keep the watch exposed to bright light

		Bright light								The electricity generated by the solar cell of the watch is

										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,
						Solar cell				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. Even if the face of the watch is
										blocked only partially from light, charging will be reduced
										significantly.
