How a Radio-controlled Watch Works What is a radio-controlled watch? A radio-controlled watch is designed to receive a time calibration signal that contains standard time data and adjust its current time setting accordingly. 4RANSMITTER #ESIUM ATOMIC CLOCK ,ONG WAVE TIME CALIBRATION SIGNAL 7ATCH After the watch receives the Standard Time signal, it performs internal calculations to determine the current time. Because of this, there may be an error of up to one second in the displayed time.
Calibration Signal •• The Japanese calibration signal (Call Sign: JJY) is maintained by the National Institute of Information and Communications Technology (NICT). It is transmitted 24 hours a day from Mt. Otakadoya (40 kHz) located in Tamura-gun, Fukushima Prefecture, and from Mt. Hagane (60 kHz) located on the border between Saga Prefecture and Fukuoka Prefecture. •• The Chinese time calibration signal (BPC) is maintained by National Time Service center (NTSC) of China and is transmitted from Shangqiu.
Note that transmission of the Japanese calibration signal may be interrupted occasionally due to maintenance, lightning, etc. For more information, visit the website of the Japan Standard Time Group of the National Institute of Information and Communications Technology (NICT) at the following URL. http://jjy.nict.go.jp •• Note that the above URL is subject to change.
Reception Ranges The table below shows the time calibration signal that the watch receives when a particular city code is selected as your Home City. •• For information about the Home City setting, see page 62. See page 56 for details on city codes.

Reception Time A receive operation can take anywhere from about two to seven minutes. •• Under certain conditions, a receive operation can take as long as 14 minutes. Positioning the Watch for Best Reception Remove the watch from your wrist and place it somewhere so its top (12 o’clock side, where the antenna is located) is facing approximately in the direction of the signal transmitter. Keep the watch away from metal objects.
Important! Reception is difficult and may even be impossible in the locations described below. Avoid such locations when performing signal reception. •• You should think of your watch as operating like a radio or TV when it is receiving the calibration signal.
Auto receive •• You will need to perform the operations described below before you can use Auto Receive. •• In the Timekeeping Mode, select a Home City that supports reception of your local time calibration signal. See pages 27 to 29, and page 62 for more information. •• Put the watch into the Timekeeping Mode or World Time Mode. See “Modes and Indicators” on page 16. •• During the Auto Receive times, position the watch correctly for best reception.
•• Calibration signal reception will start automatically whenever the current time in the Timekeeping mode (page 16) reaches one of the Auto Receive Start Times shown below. Auto receive can be performed up to six times a day, but any time a signal receive operation is successful, no more auto receive operations are performed that day. Note that the Auto Receive Start Times differ according to the current Home City setting and the summer time setting.
When reception is successful After a receive operation is complete, the watch will return to regular timekeeping, which will show the newly adjusted time. When reception fails This will cause the watch to return to regular timekeeping without adjusting the time setting. Using Manual Receive Hold down A for about two seconds in the Timekeeping Mode. •• You will need to perform the operations described below before you can perform Manual Receive.
While reception is in progress... •• The second hand will indicate the current reception status. READY (or R): Unstable reception WORK (or W): Stable reception •• Keep the watch in a location where reception is stable while a receive operation is in progress. •• Do not move the watch while signal reception is in progress (second hand 7/2+ OR 7 at “WORK”). •• Even under optimum reception conditions, it can take about 10 seconds for reception to stabilize.
When reception is complete... 9%3 OR 9 •• When signal reception is successful, the second hand will move to YES (Y for some models) and the current time setting will be adjusted according to the received information. Next, the watch will return to regular timekeeping. •• If signal reception is not successful, the second hand will move to NO (N for some models). Then after about five seconds the watch will return to regular timekeeping. ./ OR .

Operating Precautions ■■ Water Resistance •• The following applies to watches with WATER RESIST or WATER RESISTANT marked on the back cover.
•• A trained technician will know how to check your watch for proper water resistance whenever you have its battery replaced. Battery replacement requires the use of special tools. Always request battery replacement from your original retailer or from an authorized CASIO service center. •• Some water-resistant watches come with fashionable leather bands. Avoid swimming, washing, or any other activity that causes direct exposure of a leather band to water.
■■ Temperature •• Never leave the watch on the dashboard of a car, near a heater, or in any other location that is subject to very high temperatures. Do not leave the watch where it will be exposed to very low temperatures, either. Temperature extremes can cause the watch to lose or gain time, to stop, or otherwise malfunction. ■■ Impact •• Your watch is designed to withstand impact incurred during normal daily use and light activity such as playing catch, tennis, etc.
■■ Storage •• If you do not plan to use the watch for a long time, wipe it thoroughly free of all dirt, sweat, and moisture, and store it in a cool, dry place. ■■ Resin Components •• Allowing the watch to remain in contact with other items or storing it together with other items while it is wet for long periods can cause the color of the other items to transfer to the resin components of the watch.
•• Leaving a leather band where it is exposed to direct sunlight (ultraviolet rays) for long periods or failure to clean dirt from a leather band for long periods can cause it to become discolored. Important! •• Subjecting a natural leather or imitation leather band to rubbing or dirt can cause color transfer and discoloration. ■■ Metal Components •• Failure to clean dirt from a metal band can lead to formation of rust, even if the band is stainless steel or plated.
Battery •• The special rechargeable battery used by your watch is not intended to be removed or replaced by you. Use of a rechargeable battery other than the special one specified for this watch can damage the watch. •• The rechargeable battery is charged when the solar cell is exposed to light, and so regular periodic replacement is not required. However, charging and discharging of the battery over the years leads naturally to a loss in its ability to sustain a charge and shortens its operating time.
User Maintenance ■■ Caring for Your Watch •• A dirty or rusty case or band can soil the sleeve of your clothing, cause skin irritation, and even interfere with watch performance. Be sure to keep the case and band clean at all times. Rust tends to form easily after the watch is exposed to seawater and then left without cleaning. •• Sometimes a smudge like pattern may appear on the surface of a resin band. This will not have any affect on your skin or clothing. Wipe the band with a cloth to clean it.
■■ Dangers of Poor Watch Care Rust •• Though the stainless steel used for the watch is highly rust-resistant, rust can form if the watch is not cleaned after it becomes dirty. Failure of oxygen to come into contact with the metal because it is dirty causes breakdown of the oxidization layer on the metal surface, which leads to the formation of rust.
