MO0606-EA Operation Guide 2924 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. • The initial factory default Home City setting is TYO (Tokyo). This means that the watch is initially configured to receive the time calibration signals transmitted in Japan. If you are planning to use the watch in North America, be sure to change the Home City setting. “To set your Home City” for more information. • This watch does not have a time zone that corresponds to the Greenwich Mean Time differential of –3.5 hours. Because of this, the radio-controlled timekeeping and World Time functions will not display the correct time for Newfoundland, Canada. • The actual level at which some functions are disabled depends on the watch model. • Frequent display illumination can quickly run down the battery and require charging. The following guidelines give an idea of the charging time required to recover from a single illumination operation. Approximately five minutes exposure to bright sunlight coming in through a window Approximately 50 minutes exposure to indoor fluorescent lighting • Be sure to read “Power Supply” for important information you need to know when exposing the watch to bright light. Keep the watch exposed to bright light If the display of the watch is blank, it means that the watch’s Power Saving function has turned off the display to conserve power. • See “Power Saving Function” for more information. l l l l l l l l l l l 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 only partially blocked from light, charging will be reduced significantly. If the display of the watch is blank... About This Manual • Depending on the model of your watch, display text appears either as dark figures on a light background, or light figures on a dark background. All sample displays in this manual are shown using dark figures on a light background. • Button operations are indicated using the letters shown in the illustration. • Each section of this manual provides you with the information you need to perform operations in each mode. Further details and technical information can be found in the “Reference” section. • 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 cause 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.

Press C. ▲ Countdown Timer Mode ▲ ▲ Stopwatch Mode Radio-controlled Atomic Timekeeping PM indicator Month – Day Hour : Minutes Seconds This watch receives a time calibration signal and updates its time setting accordingly. The time calibration signal includes both Standard Time and Daylight Saving Time (summer time) data. • This watch is designed to pick up the time calibration signal transmitted in the United States (Fort Collins, Colorado) and the time calibration signals transmitted in Japan. • The U.S. time calibration signal can be picked up by the watch while in North America*. term “North America” in this User’s Guide refers to the * The area that consists of Canada, the continental United States, and Mexico. Current Time Setting This watch adjusts its time setting automatically in accordance with a time calibration signal. You can also perform a manual procedure to set the time and date, when necessary. • The first thing you should do after purchasing this watch is to set your Home City, which is the city where you will use the watch normally. For more information, see “To set your Home City” below. • When using the watch outside of the range of the U.S. and Japanese time signal transmitters, you need to adjust the time manually as required. See “Timekeeping” for information about manual settings. Important! • Normally, your watch should show the correct time as soon as you select your Home City code. If it does not, it should adjust automatically after the next auto receive operation (in the middle of the night). You can also perform manual receive or you can set the time manually. • If you are in an area that does not use Daylight Saving Time (summer time), turn off the DST setting. 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 automatically picks up the time calibration signal three times a day at midnight, 1:00 a.m., and 2:00 a.m. 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. To set your Home City City code ll ll ll l l l ll 1. In the Timekeeping Mode, hold down A until the city code starts to flash, which indicates the setting screen. 2. Use D(east) and B(west) to select the city code you want to use as your Home City. • The following are the city codes for major cities in North America. LAX: Los Angeles, San Francisco, Las Vegas, Seattle, Vancouver, Tijuana DEN: Denver, El Paso, Edmonton, Culiacan CHI: Chicago, Houston, Dallas/Fort Worth, New Orleans, Winnipeg, Mexico City NYC: New York, Detroit, Miami, Boston, Montreal • Note that this watch does not have a city code that corresponds to Newfoundland. 3.

If both the 1 o’clock and 2 o’clock signal receptions are not successful, the watch will try to receive the signal again at the top of each hour up until 5:00 a.m. or until one more reception is successful. Note • Auto receive works only while the watch is in the Timekeeping Mode or World Time Mode. Auto receive is not performed if an auto receive time is reached while an alarm is sounding, while a countdown timer operation is in progress, or if a setting screen (a screen with a flashing setting) is on the display. • 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. • When auto receive is turned on, the watch receives the calibration signal for two to five minutes everyday when the Timekeeping Mode time reaches each of the calibration times. Do not perform any button operation within five 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 time kept in the Timekeeping Mode. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the Timekeeping Mode time is actually the correct time. • If more than one auto receive is successful, the watch uses the data from the last successful receive to adjust settings. When only one reception is successful, the watch uses the data of the successful reception. About the Receiving Indicator The receiving indicator shows the strength of the calibration signal being received. For best reception, be sure to keep the watch in a location where signal strength is strongest. 3. Press D to toggle auto receive on (ON) and off (OFF). 4.

The illustration shown below shows how you should position the watch for charging. Solar cell 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 only partially blocked from light, charging will be reduced significantly. • Since these are the specs, we can include all the technical details. • Watch is not exposed to light • Display on 18 hours per day, sleep state 6 hours per day • 1 illumination operation (1.5 seconds) per day • 10 seconds of alarm operation per day • 15 minutes of signal reception per day • Stable operation is promoted by frequent charging. The battery power indicator shows you the current power level of the rechargeable battery. Level Battery Power Indicator Function Status ▲ Battery Power Indicator and Recover Indicator ▲ Outdoor Sunlight (50,000 lux) 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 4 and when you have the battery replaced. • Turn on the watch’s Power Saving function and keep it in an area normally exposed to bright light when storing it for long periods. This helps to keep the rechargeable battery from going dead. ▲ ▲ Recovery Times The table below shows the amount exposure that is required to take the battery from one level to the next.

For more information, see “Daylight Saving Time (DST)” below. • For information about setting other than the time and date, see the following. Power Saving: Power Saving Function 4. Press A to exit the setting screen. 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 signal transmitted from Fort Collins includes 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 received time signal. • The time calibration signals transmitted from Fukushima and Fukuoka/Saga do not include summer time data. • The default DST setting is Auto DST (A) whenever you select LAX, DEN, CHI, NYC, or TYO as your Home City code. • If you experience problems receiving the time calibration signal in your area, it is probably best to switch between Standard Time and Daylight Saving Time (summer time) manually. To change the Daylight Saving Time (summer time) setting 1. In the Timekeeping Mode, hold down A until the city code starts to flash, which indicates the setting screen. 2. Press C and the DST setting screen appears. 3. Use D to cycle through the DST settings in the sequence shown below. Auto DST (A) DST off (OF) DST on (ON) 4. When the setting you want is selected, press A to exit the setting screen. • The DST indicator appears to indicate that Daylight Saving Time is turned on. Radio-controlled Atomic Timekeeping Precautions • Strong electrostatic charge can result in the wrong time being set. • The time calibration signal is bounced 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. • The watch is designed to update the date and day of the week automatically for the period January 1, 2000 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. • Normally, the signal reception date shown by the Last Signal screen is the date data included in the received time calibration signal. When only time data is received, however, the Last Signal screen shows the date as kept in the Timekeeping Mode at the time of signal reception. • If you are in an area where proper time calibration signal reception is impossible, the watch keeps time within ±15 seconds a month at normal temperature. • If you have problems with proper time calibration signal reception or if the time setting is wrong after signal reception, check your current city code, DST (summer time), and auto receive settings. The following are the initial factory defaults for these settings. Setting Initial Factory Default City code TYO (Tokyo) DST (summer time) DST A (Auto switching) Auto receive (Auto receive) Reference To configure auto receive settings for Japan This section contains more detailed and technical information about watch operation.

The watch automatically selects the transmitter whose signal is strongest. Signal reception can take up to 12 minutes when this option is selected. : Auto receive on for reception of the Fukushima signal (40kHz). : Auto receive on for reception of the Fukuoka/Saga signal (60kHz). : Auto receive off. 4. Press A to exit the setting screen. • To return to the Timekeeping Mode from the last signal screen, press D. Timekeeping • Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes. • The day of the week is displayed automatically in accordance with the date (year, month, and day) settings. • The year can be set in the range of 2000 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 4. • The current time for all city codes in the Timekeeping Mode and World Time Mode is calculated in accordance with the Greenwich Mean Time (GMT) differential for 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. 12-hour/24-hour Timekeeping Formats The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also applied in all other modes. • With the 12-hour format, the PM indicator (P) appears on the display for times in the range of noon to 11:59 p.m. and no indicator appears for times in the range of midnight to 11:59 a.m. • With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without any indicator. Illumination Precautions • The electro-luminescent panel that provides illumination loses power after very long use. • Illumination may be hard to see when viewed under direct sunlight. • The watch may emit an audible sound whenever the display is illuminated. This is due to vibration of the EL panel used for illumination, and does not indicate malfunction. • Illumination turns off automatically whenever an alarm sounds. • Frequent use of illumination runs down the battery. 5 Operation Guide 2924 Auto light switch precautions • The auto light switch is turned off automatically whenever battery power is at Level 3. • Wearing the watch on the inside of your wrist, movement of your arm, or vibration of your arm can cause frequent activation of the auto light switch and illumination of the display. To avoid running down the battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination. • Note that wearing the watch under your sleeve while the auto light switch is turned on can cause frequent illumination of the display and can run down the battery. • Illumination may not turn on if the face of the watch is more than 15 degrees above or below parallel. Make sure that the back of your hand is parallel to the ground. • Illumination turns off after the preset illumination duration (see “To set the time and date”), even if you keep the watch pointed towards your face. • Static electricity or magnetic force can interfere with proper operation of the auto light switch. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards you again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again. • Under certain conditions, illumination may not turn on until about one second after you turn the face of the watch towards you. This does not necessarily indicate malfunction of the auto light switch. • You may notice a very faint clicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.
