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				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.
						••When you are not wearing the watch on your wrist, position the face so it is
			Solar cell			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.

Time Calibration Signal Reception

There are two different methods you can use to receive the time calibration signal: auto receive and manual receive.

••Auto Receive

With auto receive, the watch receives the time calibration signal automatically up to six times a day (five times for the China signal). When any auto receive is successful, remaining auto receive operations are not performed. For more information, see “About Auto Receive”.

••Manual Receive

Manual receive lets you start a time calibration receive operation with the press of a button. For more information, see “To perform manual receive”.

Important!

••When getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 12 o’clock side pointing towards a window. This watch is designed to receive a time calibration signal late at night. Because of this, you should place the watch near a window as shown in the illustration when you take it off at night. Make sure there are no metal objects nearby.
