MO0608-EA Operation Guide 2628 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 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. Keep the watch exposed to bright light 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. Charging is reduced significantly if the face is only partially covered. • The actual level at which some functions are disabled depends on the watch model. • Frequent display illumination can run down the battery quickly 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. If the display of the watch is blank... 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. About This Manual • 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.

Radio-controlled Atomic Timekeeping PM Day of week 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 from Fort Collins, Colorado (USA). Reception is possible within 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 normally will use the watch. For more information, see “To set your Home City” below. • When using the watch outside of the range of the transmitter in Fort Collins, 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 picks up the time calibration signal automatically five times a day at midnight, 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 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 lll lll l l ll ll l l lll E/C/M/P indicator 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(P (Pacific) indicator): Los Angeles, San Francisco, Las Vegas, Seattle, Vancouver, Tijuana DEN(M (Mountain) indicator): Denver, El Paso, Edmonton, Culiacan CHI(C (Central) indicator): Chicago, Houston, Dallas/Fort Worth, New Orleans, Winnipeg, Mexico City NYC(E (Eastern) indicator): New York, Detroit, Miami, Boston, Montreal • Note that this watch does not have a city code that corresponds to Newfoundland. 3. Press A twice to exit the setting screen. • The first press of A displays the 12/24-hour setting screen. Pressing A again exits the setting screen. 12 o’clock 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 or office equipment, or a mobile phone Near a Near highconstruction tension site, airport, or power lines other sources of electrical noise Among or behind mountains 1 Operation Guide 2628 • Signal reception normally is better at night than during the day. • Time calibration signal reception takes from two to six minutes. Take care that you do not perform any button operations or move the watch during this time. Reception Range 2,000 miles 600 miles To display the Last Signal screen In the Timekeeping Mode, press D to display the Last Signal screen (indicated by GET).

PM indicator Receive time Day of week ▲ ▲ Press D. Fort Collins • At distances further than about 600 miles (1,000 kilometers) from the transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception. • Even when the watch is within the reception range of the transmitter, signal reception is 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. • See the information under “Signal Receive Troubleshooting” if you experience problems with time calibration signal reception. About Auto Receive When auto receive is turned on, the watch starts to receive the time calibration signal automatically when the time in the Timekeeping Mode reaches midnight, 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will also perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled auto receives are successful. Note • The auto receive operation is performed only if the watch is in the Timekeeping Mode or World Time Mode when one of the calibration times is reached. It is not performed if a calibration time is reached while an alarm is sounding, or while you are configuring settings (while settings are flashing on the display). • Auto receive 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 six minutes everyday when the Timekeeping Mode time reaches each of the calibration times. Avoid performing any button operation within six 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 actually is the correct time. • When two, three, or four receptions are successful, the watch uses the data of the last reception for calibration. 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. Check the following points whenever you experience problems with calibration signal reception.

Power Supply 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. 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. Charging is reduced significantly if the face is only partially covered. 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 exposed to bright light when storing it for long periods. This helps to keep the rechargeable battery from going dead. Battery Power Indicator and Recover Indicator The battery power indicator shows you the current power level of the rechargeable battery.

The appearance of the LCD should become normal again when the watch returns to a lower temperature. / Press A. C City/Auto receive Settings Note • Auto DST (AUTO) can be selected only while HNL, ANC, LAX, DEN, CHI, or NYC is selected as the Home City code. For more information, see “Daylight Saving Time (DST)” below. • The auto receive setting is used for time calibration signal reception only. See “About Auto Receive” for details. • For details about power saving, see “Power Saving Function”. 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 default DST setting is Auto DST (AUTO) whenever you select ANC, LAX, DEN, CHI, or NYC 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. 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 (AUTO) DST off (OFF) DST on (ON) Receive time Day of week 4.

Auto Return Features • If you leave the watch in the Sunrise/Sunset Mode, Bearing Mode, Time Recorder Mode, or Alarm Mode for two or three minutes without performing any operation, it returns to the Timekeeping Mode automatically. • If you leave a screen with flashing digits on the display for two or three minutes without performing any operation, the watch saves anything you have input up to that point and exits the setting screen automatically. Scrolling The B and D buttons are used in various modes and setting screens to scroll through data on the display. In most cases, holding down these buttons during a scroll operation scrolls through the data at high speed. 5 Operation Guide 2628 ll 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. 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 as well as movement or vibration of your arm can cause the auto light switch to activate and illuminate the display. To avoid running down the battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination of the display. • 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. More than 15 degrees too high Initial Factory Default Setting City code (New York) DST (summer time) (Auto switching) Auto receive ll l l l • 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. lll Radio-controlled Atomic Timekeeping Precautions To turn Power Saving on and off 1. In the Timekeeping Mode, hold down A. This causes Power Saving on indicator the city code to flash, which indicates the setting screen. 2. Press A again. 3. Press C seven times until the Power Saving on/off screen appears. lll 4. Press D to toggle Power Saving on (ON) and off ll ll (OFF). 5. After the setting is the way you want, press A to exit the setting screen. • The Power Saving on indicator is on the display in all modes while the Power Saving is turned on. lll When you enter the Alarm or World Time Mode, the data you were viewing when you last exited the mode appears first. lllll Initial Screens (Auto receive) 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 the your Home City time setting. • GMT differential is calculated by this watch based on UTC* data. The letters “UTC” stands for “Universal Time Coordinated,” which is the world-wide scientific standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks that keep accurate 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 P (PM) indicator 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. Power Saving Function When turned on, the Power Saving function enters a sleep state automatically whenever the watch is left in an area where it is dark for a certain period. The table below shows how watch functions are affected by the Power Saving function. Display Power Saving on indicator Elapsed Time in Dark 60 to 70 minutes Blank, with the Power Saving on indicator flashing 6 or 7 days Blank, with the Power Saving on indicator not flashing Operation All functions enabled, except for the display Beeper tone, illumination, display, and auto receipt of the calibration signal are disabled. • 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 in about one second, 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.
