MO0905-EB Operation Guide 4777 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. • This watch does not have a city code that corresponds to the Greenwich Mean Time differential of –3.5 hours. Because of this, the radio-controlled atomic timekeeping function will not display the correct time for Newfoundland, Canada. Bright light l l l l l l l l l l l Keep the watch exposed to bright light Solar cell 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 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. Battery charges in the light. Solar cell (Converts light to electrical power.) Battery discharges in the dark. Bright light LEVEL 2 If the analog hands aren’t moving, it means that the power saving mode has stopped them to save battery power. • See “Power Saving” for more information. • The hands also stop whenever the battery level reaches Level 3.

If you need to pass through the World Time Mode or the Alarm Mode to get to another mode, press C (mode change) to advance to the next mode before the hands start moving. Radio-controlled Atomic Timekeeping This watch receives a time calibration signal and updates its time setting accordingly. • Supported time calibration signals: Germany (Mainflingen), England (Anthorn), United States (Fort Collins), Japan (Fukushima or Fukuoka/Saga). • See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception. Current Time Setting This watch adjusts its time setting automatically in accordance with a time calibration signal. You also can perform a manual procedure to set the time and date, when necessary. • The first thing you should do after purchasing this watch is to specify your Home City, which is the city where you will normally use the watch. For more information, see “To specify your Home City”. • When using the watch outside the areas covered by the time calibration signal transmitters, you will have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings. • The U.S. time calibration signal can be picked up by the watch while in North America. The term “North America” in this manual refers to the area that consists of Canada, the continental United States, and Mexico. 3300 To specify your Home City 1. In the Timekeeping Mode, hold down A for about five seconds. The watch will beep once after about two seconds, and then twice after about three more seconds. • This indicates the watch is in the setting mode. • Entering the setting mode will cause the stopwatch second hand to move to the city code of the currently selected Home City. 2. Use D to change the Home City setting. • Each press of D causes the stopwatch second hand to advance clockwise to the next city code. • All hands (except for the second hand) and the date display will change automatically to the applicable settings for the currently selected city code. All button City code Stopwatch operations are disabled while the hands and date second hand display are changing. • Time calibration signal reception is supported when any one of the city codes shown in the table below is selected as your Home City. German/U.K. Signal City City Name Code LON London PAR Paris ATH Athens Japan Signal City City Name Code HKG Hong Kong TYO Tokyo City Code HNL ANC LAX U.S. Signal City Code Honolulu DEN Anchorage CHI Los Angeles NYC City Name City Name Denver Chicago New York • In addition to the above, you also can select city codes that are outside the ranges of the time calibration signal transmitters supported by this watch. • Note that this watch does not have a city code that corresponds to Newfoundland. 3. After the Home City setting is the way you want, press A to return to the Timekeeping Mode. • Normally, your watch should show the correct time as soon as you specify your Home City code. If it does not, it should adjust automatically after the next auto receive operation. You also can perform manual receive or you can set the time manually. • Even if the time calibration signal is received correctly, there are some times when the analog hands may not indicate the correct time. If this happens, use the procedures under “Adjusting the Home Positions” to check the home positions of the hands, and make adjustments as required. • You can also change the Home City setting by swapping the current Home City and the currently selected World Time City. For details, see “Swapping your Home City and World Time City”. Daylight Saving Time (DST) Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time. The time calibration signals transmitted from Mainflingen (Germany), Anthorn (England), or Fort Collins (the United States) include both Standard Time and DST data. When the Auto DST setting is turned on, the watch switches between Standard Time and DST (summer time) automatically in accordance with the signals. • Though the time calibration signal transmitted by the Fukushima and Fukuoka/Saga, Japan transmitters include summer time data, summer time currently is not implemented in Japan (as of 2007). • The default DST setting is Auto DST (AUTO/AT) whenever you select LON, PAR, ATH, ANC, LAX, DEN, CHI, NYC, or TYO as your Home City code. • If you experience problems receiving the time calibration signal in your area, it probably is best to switch between Standard Time and Daylight Saving Time (summer time) manually. For more information, see “To set the time and date manually”. 1 Operation Guide 4777 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. When any auto receive is successful, the 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 facing towards a window. Make sure there are no metal objects nearby. About Auto Receive The watch receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. The reception schedule (calibration times) depends on your currently selected Home City, and whether standard time or Daylight Saving Time is selected for your Home City. Your Home City LON PAR ATH 12 o’clock HKG, TYO HNL, ANC, LAX, DEN, CHI, NYC or • Make sure the watch is facing the right way. • Proper signal reception can be difficult or even impossible under the conditions listed below. Inside or among buildings Inside a vehicle Near household appliances, office equipment, or a mobile phone Near a construction site, airport, or other sources of electrical noise Among or behind mountains Near hightension power lines Home City Code HKG*, TYO HNL*, ANC*, LAX, DEN, CHI, NYC Transmitter Anthorn (England) Mainflingen (Germany) Fukushima (Japan) Fukuoka/Saga (Japan) Fort Collins, Colorado (the United States) Frequency 60.0 kHz 77.5 kHz 40.0 kHz 60.0 kHz 60.0 kHz * The areas covered by the HKG, HNL, and ANC city codes are quite far from the time calibration signal transmitters, and so certain conditions may cause problems with signal reception. U.S. Signal Reception Ranges U.K. and German Signals 1,500 kilometers 2,000 miles (3,000 kilometers) Mainflingen Anthorn 600 miles (1,000 kilometers) Fort Collins 500 kilometers 500 kilometers Note • Auto receive is supported in all modes except while a stopwatch elapsed time operation is in progress. • Auto receipt of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the Timekeeping Mode time is set correctly). Before going to bed for the night, remove the watch from your wrist, and put it in a location where it can receive the signal easily. • The watch receives the calibration signal for two to 14 minutes every day when the time in the Timekeeping Mode reaches each of the calibration times. Do not perform any button operation within 14 minutes before or after any one of the calibration times. Doing so can interfere with correct calibration. • Remember that reception of the calibration signal depends on the current time in the Timekeeping Mode. • Signal receive is cancelled if an alarm operation starts while it is being performed. To perform manual receive 1. Place the watch on a stable surface so its 12 o’clock side is facing towards a window. 2. In the Timekeeping Mode, hold down A for about two seconds until the watch beeps. 3. The stopwatch second hand will move to R (READY) to indicate that the watch is setting up for time calibration reception. • The stopwatch second hand will move to W (WORK) and stay there while actual reception is in progress. R (READY) • If signal reception is unstable during reception, the W (WORK) Y (YES) stopwatch second hand may move between W (WORK) and R (READY). • The hour, minute, and 24-hour hands all continue to keep time normally. • The second hand will stop at “0”.* * Some models show “60” instead of “0”. 30 LON, PAR, ATH Standard Time Midnight 1:00 am 2:00 am 3:00 am 4:00 am 5:00 am Daylight Saving Time 30 • Signal reception normally is better at night than during the day. • Time calibration signal reception takes from two to seven minutes, but in some cases it can take as long as 14 minutes. Take care that you do not perform any button operations or move the watch during this time. • The time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below. If you use the watch in Japan or Europe (each of which has two different transmitter locations), it will try to receive the time calibration signal from one of the transmitters in your current location. If it cannot receive the signal, it will then try to receive the time calibration signal from the other transmitter.

Take care that you do not perform any button operations or move the watch during this time. • After signal reception is successful, the watch adjusts its hour, minute, 24-hour hand, and second hand settings, and then returns to the Timekeeping Mode. Next, the stopwatch second hand moves to Y (YES) momentarily to indicate that signal reception was successful. After about five seconds, the stopwatch second hand moves to 12 o’clock. Note • To interrupt a receive operation and return to the Timekeeping Mode, press any button. • If signal reception fails for some reason, the watch returns to normal timekeeping without making any adjustments. Next, the stopwatch second hand moves to N (NO) momentarily to indicate that signal reception failed. After about five seconds, the stopwatch second hand moves to 12 o’clock. • If the stopwatch second hand is pointing to Y (YES) or N (NO), you can return to the Timekeeping Mode by pressing any button. 500 kilometers Viewing the Latest Signal Reception Results Fukushima You can use the procedure below to check whether or not the last signal receive operation was successful. Fukuoka/Saga 1,000 kilometers 1,000 kilometers Japan Signal 30 • Signal reception may not be possible at the distances noted below during certain times of the year or day. Radio interference may also cause problems with reception. Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles) Fort Collins (United States) transmitter: 600 miles (1,000 kilometers) Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles) • Even when the watch is within the reception range of the transmitter, signal reception will be impossible if the signal is blocked by mountains or other geological formations between the watch and signal source. • Signal reception is affected by weather, atmospheric conditions, and seasonal changes. To check the latest signal reception results In the Timekeeping Mode, press A. • If the watch was able to perform a successful signal receive operation during the last receive period, the stopwatch second hand will move to Y (YES). If the watch has been unable to receive any signal successfully, the stopwatch second hand will move to N (NO). • The watch will return to the Timekeeping Mode after five seconds or when you press A. • The current receive result is cleared when the first auto receive operation is performed on the following day. This means Y (YES) indicates successful signal reception since the start of the current day. • If you adjust the time or date setting manually, the stopwatch second hand will move to N (NO). 2 Operation Guide 4777 What you should do • Perform manual signal receive or wait until the next auto signal receive operation is performed. • Stop the stopwatch operation. • Check to make sure the watch is in a location where it can receive the signal. • Select the correct Home City. • Enter the Home Position Adjustment Mode and adjust the home position. • For further information, see “Important!” under “Time Calibration Signal Reception” and “Radio-controlled Atomic Timekeeping Precautions”. 30 Problem Probable Cause The • You changed the time setting stopwatch manually. second hand • You performed some button operation during the auto receive operation. is pointing at • The stopwatch is performing an N (NO). elapsed time measurement operation. • Signal reception results are reset at the first time of the next receive period.

Exposure Level (Brightness) Approximate Exposure Time Outdoor sunlight (50,000 lux) 8 minutes Sunlight through a window (10,000 lux) 30 minutes Daylight through a window on a cloudy day (5,000 lux) 48 minutes Indoor fluorescent lighting (500 lux) 8 hours • Since these are the specs, we can include all the technical details. • Watch is not exposed to light • Internal timekeeping • Analog hands operational 18 hours per day, sleep state 6 hours per day • 10 seconds of alarm operation per day • 1 time calibration reception per day • Stable operation is promoted by frequent charging. Recovery Times The table below shows the amount exposure that is required to take the battery from one level to the next. Exposure Level (Brightness) Level 3 Level 2 Solar cell Important! • Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is blocked from exposure to light can cause rechargeable battery power to run down. Make sure that the watch is exposed to bright light whenever possible. • This watch uses a special rechargeable battery to store power produced by the solar cell, so regular battery replacement is not required. However, after very long use, the rechargeable battery may lose its ability to achieve a full charge. If you experience problems getting the special rechargeable battery to charge fully, contact your dealer or CASIO distributor about having it replaced. • Never try to remove or replace the watch’s special battery yourself. Use of the wrong type of battery can damage the watch. • The current time and all other settings return to their initial factory defaults whenever battery power drops to Level 3 and when you have the battery replaced. • Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps to keep the rechargeable battery from going dead. Outdoor sunlight (50,000 lux) Sunlight through a window (10,000 lux) Daylight through a window on a cloudy day (5,000 lux) Indoor fluorescent lighting (500 lux) ▲ This watch is equipped with a solar cell and a special rechargeable battery (secondary battery) that is charged by the electrical power produced by the solar cell. The illustration shown below shows how you should position the watch for charging. Level 1 ▲ ▲ Power Supply Example: Orient the watch so its face is pointing at a light source. • The illustration shows how to position a watch with a resin band. • Note that charging efficiency drops when any part of the solar cell is blocked by clothing, etc. • You should try to keep the watch outside of your sleeve as much as possible. Even if the face of the watch is blocked from light only partially, charging will be reduced significantly. Approximate Exposure Time 1 hour 20 hours 2 hours 76 hours 4 hours ––– 37 hours ––– • The above exposure time values are all for reference only. Actual required exposure times depend on lighting conditions. Reference This section contains more detailed and technical information about watch operation. It also contains important precautions and notes about the various features and functions of this watch. Auto Return Features • If you leave the watch in the Alarm Mode for two or three minutes without performing any operation, it returns to the Timekeeping Mode automatically. • If you do not perform any operation for about two or three minutes while a setting mode is selected, the watch will exit the setting mode automatically. High-Speed Movement • The D and B buttons are used to change the hand setting in various setting modes. In most cases, holding down these buttons will start high-speed movement of the applicable hand(s) and day. • High-speed movement of the hands and day will continue until you press any button, or until the moving hand(s) and day finish one complete cycle. – One complete cycle for the hands is one revolution (360 degrees) or 24 hours. – One complete cycle for the day is 31 days. 4 Operation Guide 4777 Radio-controlled Atomic Timekeeping Precautions • Strong electrostatic charge can result in the wrong time being set. • The time calibration signal bounces off the ionosphere. Because of this, such factors as changes in the reflectivity of the ionosphere, as well as movement of the ionosphere to higher altitudes due to seasonal atmospheric changes or the time of day may change the reception range of the signal and make reception temporarily impossible. • Even if the time calibration signal is received properly, certain conditions can cause the time setting to be off by up to one second. • The current time setting in accordance with the time calibration signal takes priority over any time settings you make manually. • The watch is designed to update the date and day of the week automatically for the period January 1, 2001 to December 31, 2099. Setting of the date by the time calibration signal cannot be performed starting from January 1, 2100. • This watch can receive signals that differentiate between leap years and non-leap years. • Though this watch is designed to receive both time data (hour, minutes, seconds) and date data (year, month, day), certain signal conditions can limit reception to time data only. • If you are in an area where proper time calibration signal reception is impossible, the watch keeps time within ±20 seconds a month at normal temperature. Timekeeping • The year can be set in the range of 2001 to 2099. • The watch’s built-in full automatic calendar makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except after you have the watch’s battery replaced or when battery power drops to Level 3. • The date will change automatically when the current time reaches midnight. The date change at the end of the month may take more time than normal. • The current time for all city codes in the Timekeeping Mode is calculated in accordance with the Greenwich Mean Time (GMT) differential of each city, based on your Home City time setting. • GMT differential is calculated by this watch based on Universal Time Coordinated (UTC*) data. * UTC is the world-wide scientific standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks that keep time accurately to within microseconds. Leap seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation. The reference point for UTC is Greenwich, England. Power Saving Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving. • There actually are two sleep state levels: “second hand sleep” and “function sleep”. Elapsed Time in Dark Operation 60 to 70 minutes (second hand sleep) Second hand only is stopped, all other functions are enabled. 6 or 7 days (function sleep) • All functions, including analog timekeeping, disabled • Internal timekeeping maintained • Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state. • The watch will not enter the sleep state between 6:00 AM and 9:59 PM. If the watch is already in the sleep state when 6:00 AM arrives, however, it will remain in the sleep state. To recover from the sleep state Perform any one of the following operations. • Move the watch to a well-lit area. • Press any button.
