1 MO0812-EB Getting Acquainted Congratuations upon your seection of this CASIO watch. To get the most out of your purchase, be sure to read this manua carefuy. This watch does not have a Time Zone that corresponds to the Greenwich Mean Time differentia of 3.5 hours. Because of this, the radio-controed atomic timekeeping function wi not dispay the correct time for Newfoundand, Canada. Your watch switches automaticay between Standard Time and Dayight Saving Time (summer time). Note, however, that switching cannot be performed correcty if the watch is not abe to receive the time caibration signa. If you notice that the current time is not dispayed propery, use the procedure under To perform manua receive or To set the time and date manuay to correct it. Keep the watch exposed to bright ight The eectricity generated by the soar ce of the watch is Bright ight stored by a buit-in battery. Leaving or using the watch where it is not exposed to ight causes the battery to run down. Make sure the watch is exposed to ight as much as possibe. When you are not wearing the watch on your wrist, Soar ce position the face so it is pointed at a source of bright ight. You shoud try to keep the watch outside of your seeve as much as possibe. Even if the face of the watch is bocked ony partiay from ight, charging wi be reduced significanty. The watch continues to operate, even when it is not exposed to ight. Leaving the watch in the dark can cause the battery to run down, which wi resut in some watch functions to be disabed. If the battery goes dead, you wi have to re-configure watch settings after recharging. To ensure norma watch operation, be sure to keep it exposed to ight as much as possibe. Battery charges in the ight. Battery discharges in the dark. Soar ce (Converts ight to Bright ight Some functions disabed. eectrica power.)

Mode Hand Setting Mode Dua Time Mode Aarm Mode Radio-controed Atomic Timekeeping This watch receives a time caibration signa and updates its time setting accordingy. The time caibration signa incudes both Standard Time and Dayight Saving Time (summer time) data. This watch is designed to pick up the time caibration signa transmitted in the United States (Fort Coins, Coorado) and the time caibration signas transmitted in Japan. The U.S. time caibration signa can be picked up by the watch whie in North America*. * The term North America in this manua refers to the area that consists of Canada, the continenta United States, and Mexico. See the information under Signa Reception Troubeshooting if you experience probems with time caibration signa reception. Current Time Setting This watch adjusts its time setting automaticay in accordance with a time caibration signa. You aso can perform a manua procedure to set the time and date, when necessary. The first thing you shoud do after purchasing this watch is to specify your Home Time Zone, which is the time zone where you normay wi use the watch. For more information, see To specify your Home Time Zone beow. When using the watch outside the range of the time signa transmitter, you have to adjust the current time setting manuay as required. See Timekeeping for more information about manua time settings. To specify your Home Time Zone DST indicator 1. In the Timekeeping Mode, hod down A unti the GMT differentia vaue starts to fash, which indicates the setting screen. The GMT differentia vaue indicates the time difference in hours between Greenwich Mean Time and the currenty seected time zone. The second hand wi move at high speed to the 12 o cock position, where it wi stop. The DST indicator indicates that Dayight Saving Time (summer time) is turned on for the currenty seected time zone. GMT differentia vaue Minus sign 2. Use B (+) to seect the time zone you want to use as your Home Time Zone. 5.0 (DST 4.0): New York, Miami, Toronto, Montrea, Detroit, Boston, Panama City, Havana, Lima, Bogota 6.0 (DST 5.0): Chicago, Mexico City, Winnipeg, Houston, Daas/Fort Worth, New Oreans 7.0 (DST 6.0): Denver, Edmonton, E Paso 8.0 (DST 7.0): Los Angees, Vancouver, San Francisco, Las Vegas, Seatte/Tacoma, Dawson City 9.0 (DST 8.0): Anchorage, Nome 10.0 (DST 9.0): Honouu, Papeete 8.0 (DST 9.0): Hong Kong, Singapore, Kuaa Lumpur, Beijing, Taipei, Mania, Perth, Uaanbaatar 9.0 (DST 10.0): Tokyo, Seou, Pyongyang 3. Press A to exit the setting screen. The second hand wi advance at high speed to the correct position and resume norma movement from there. Normay, your watch shoud show the correct time as soon as you specify your Home Time Zone. If it does not, it shoud adjust automaticay after the next auto receive operation (in the midde of the night). You aso can perform manua receive or you can set the time manuay. Seecting 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 8.0, or 9.0 ( 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 9.0, or 10.0 whie DST is turned on) as your Home Time Zone turns on auto receive automaticay. When auto receive is turned on and you are within the reception range, the watch wi receive the time caibration signa from the appicabe transmitter automaticay (in the midde of the night) and update its settings accordingy. For information about the reationship between time zones (GMT differentia vaues) and transmitters, see Home Time Zones and Transmitters. See the maps under Approximate Reception Ranges for information about the reception ranges of the watch. If you are in an area that does not use Dayight Saving Time (summer time), turn off the DST setting. Even if the time caibration signa is received correcty, there are some times when the anaog 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. 1

2 Time Caibration Signa Reception There are two different methods you can use to receive the time caibration signa: auto receive and manua receive. Auto Receive With auto receive, the watch receives the time caibration signa automaticay up to six times a day. When any auto receive is successfu, the remaining auto receive operations are not performed. For more information, see About Auto Receive. Manua Receive Manua receive ets you start a time caibration receive operation with the press of a button. For more information, see To perform manua receive. Important! When getting ready to receive the time caibration signa, position the watch as shown in the nearby iustration, with its 12 o cock side facing towards a window. This watch is designed to receive a time caibration signa ate at night. Because of this, you shoud pace the watch near a window as shown in the iustration when you take it off at night. Make sure there are no meta objects nearby. 12 o cock Make sure the watch is facing the right way. Proper signa reception can be difficut or even impossibe under the conditions isted beow. Inside or among buidings Inside a vehice Near househod appiances, office equipment, or a mobie phone or Near a construction site, airport, or other sources of eectrica noise Near hightension power ines Among or behind mountains Signa reception normay is better at night than during the day. Time caibration signa reception takes from two to seven minutes, but in some cases it can take as ong as 14 minutes. Take care that you do not perform any button operations or move the watch during this time. The time caibration signa the watch wi attempt to pick up depends on its current Home Time Zone setting as shown beow. If you use the watch in Japan (which has two different transmitter ocations), it wi try to receive the time caibration signa from one of the transmitters in your current ocation. If it cannot receive the signa, it wi then try to receive the time caibration signa from the other transmitter.

Note, however, that auto receive is not performed if a caibration time is reached in the foowing cases: Whie an aarm is sounding Whie a button is depressed Auto receive of the caibration signa is designed to be performed eary in the morning, whie you seep (provided that the Timekeeping Mode time is set correcty). Before going to bed for the night, remove the watch from your wrist, and put it in a ocation where it can receive the signa easiy. The watch receives the caibration signa for two to 14 minutes every day when the time in the Timekeeping Mode reaches each of the caibration times. Avoid performing any button operation within 14 minutes before or after any one of the caibration times. Doing so can interfere with correct caibration. Remember that reception of the caibration signa depends on the current time in the Timekeeping Mode. To perform manua receive 1. Pace the watch on a stabe surface so its 12 o cock side is facing towards a window. 2. In the Timekeeping Mode, hod down A for about two seconds unti the watch beeps. 3. The second hand wi move to R (READY) to indicate that the watch is setting up for time caibration reception. R (READY) W (WORK) Y (YES) N (NO) The second hand wi move to W (WORK) and stay there whie actua reception is in progress. The hour and minute hands continue to keep time normay. Time caibration signa reception takes from two to seven minutes, but in some cases it can take up to 14 minutes. Take care that you do not perform any button operations or move the watch during this time. If reception is successfu, the second hand wi move to Y (YES). Five seconds ater, the hands wi move to the correct time. Note To interrupt a receive operation and return to the Timekeeping Mode, press any button. If reception is not successfu, the second hand wi move to N (NO). Five seconds ater, the second hand wi resume norma operation, without any adjustment of the hand setting. If the second hand is pointing to Y (YES) or N (NO), you can return to the Timekeeping Mode by pressing any button. Viewing the Latest Signa Reception Resuts You can use the procedure beow to check whether or not the ast signa receive was successfu. To check the atest signa reception resuts In the Timekeeping Mode, press A. If the watch was abe to perform a successfu signa receive operation since midnight, the second hand wi move to Y (YES). If the watch has been unabe to receive any signa successfuy, the second hand wi move to N (NO). The watch wi return to the Timekeeping Mode after five seconds. The current receive resut is ceared when the first auto receive operation is performed on the foowing day. This means Y (YES) indicates successfu signa reception since the start of the current day. If you adjust the time or date setting manuay, the second hand wi move to N (NO). Signa Reception Troubeshooting Check the foowing points whenever you experience probems with signa reception. Probem The second hand is pointing at N (NO). Time setting is incorrect foowing signa reception. Probabe Cause You changed the time setting manuay. You performed some button operation during the auto receive operation. Signa reception resuts are reset when the first auto receive operation of the day is performed. The Home Time Zone setting is not correct for the area where you are using the watch. The home position of the hands is off. What you shoud do Perform manua signa receive or wait unti the next auto signa receive operation is performed. Check to make sure the watch is in a ocation where it can receive the signa. Seect the correct Home Time Zone. Enter the Hand Setting Mode and adjust the home position.

The watch s auto ight switch turns on iumination automaticay when you ange the watch towards your face. The auto ight switch must be turned on for it to operate. See Iumination Precautions for other important information. To iuminate the face of the watch In the Timekeeping Mode (except when a setting screen is on the dispay), press B to iuminate the face of the watch for about one second. The above operation turns on iumination regardess of the current auto ight switch setting. About the Auto Light Switch Turning on the auto ight switch causes the face to iuminate, whenever you position your wrist as described beow in any mode. Note that this watch features a Fu Auto LED Light, so the auto ight switch operates ony when avaiabe ight is beow a certain eve. It does not iuminate the dispay under bright ight. The auto ight switch is aways disabed, regardess of its on/off setting, when any one of the foowing conditions exists. When an aarm is sounding Whie an auto receive operation is in progress Whie a button is depressed Moving the watch to a position that is parae to the ground and then titing it towards you at more than 40 degrees causes iumination to turn on. Wear the watch on the outside of your wrist. Parae to ground More than 40 Warning! Aways make sure you are in a safe pace whenever you are reading the face of watch using the auto ight switch. Be especiay carefu when running or engaged in any other activity that can resut in accident or injury. Aso take care that sudden iumination by the auto ight switch does not starte or distract others around you. When you are wearing the watch, make sure that its auto ight switch is turned off before riding on a bicyce, or operating a motorcyce or any other motor vehice. Sudden and unintended operation of the auto ight switch can create a distraction, which can resut in a traffic accident and serious persona injury. To turn the auto ight switch on and off In the Timekeeping Mode (except when a setting screen is on the dispay), hod down B for about three seconds to togge the auto ight switch on and off. Turning on the auto ight switch wi cause the watch to beep. The ON indicator (ON) wi appear and the ight wi turn on for 1.5 seconds. Turning off the auto ight switch wi cause the watch to beep. The OFF indicator (OF) wi appear for 1.5 seconds. The ight wi not turn on. Power Suppy This watch is equipped with a soar ce and a specia rechargeabe battery (secondary battery) that is charged by the eectrica power produced by the soar ce. The iustration shown beow shows how you shoud position the watch for charging. Exampe: Orient the watch so its face is Soar ce pointing at a ight source. The iustration shows how to position a watch with a resin band. Note that charging efficiency drops when any part of the soar ce is bocked by cothing, etc. You shoud try to keep the watch outside of your seeve as much as possibe. Even if the face of the watch is bocked from ight ony partiay, charging wi be reduced significanty. 3

4 Important! Storing the watch for ong periods in an area where there is no ight or wearing it in such a way that it is bocked from exposure to ight can cause rechargeabe battery power to run down. Make sure that the watch is exposed to bright ight whenever possibe. This watch uses a specia rechargeabe battery to store power produced by the soar ce, so reguar battery repacement is not required. However, after very ong use, the rechargeabe battery may ose its abiity to achieve a fu charge. If you experience probems getting the specia rechargeabe battery to charge fuy, contact your deaer or CASIO distributor about having it repaced. Never try to remove or repace the watch s specia battery yoursef. Use of the wrong type of battery can damage the watch. The current time and a other settings return to their initia factory defauts whenever battery power drops to Leve 3 and when you have the battery repaced. Keep the watch in an area normay exposed to bright ight when storing it for ong periods. This heps to keep the rechargeabe battery from going dead. Battery Power Leves Battery power eve is indicated by hand movement and a dispay indicator. Jumps 2 seconds Hand Movement/ Leve Dispay Indicator 1 Norma 2 jumps every two seconds. LO dispayed. 3 A hands stopped. Dispay is bank. Function Status A functions enabed. Iumination, aarm and signa reception disabed. A functions disabed. Battery eve is very ow when the second hand jumps every two seconds and the dispay shows LO. Expose the watch to ight and charge the battery as soon as possibe. When battery power is at Leve 2, time caibration signa reception is disabed. Aarm operation can cause hand movement to stop due to the sudden temporary drop in battery power. This does not indicate mafunction, and norma operation wi resume when the watch is exposed to ight. Though hand movement stops, timekeeping continues internay, and the hands wi be adjusted to the correct setting when norma operation returns. At Leve 3, a functions are disabed and settings return to their initia factory defauts. Functions are enabed once again after the rechargeabe battery is charged, but you need to set the time and date, after the battery reaches Leve 1 from Leve 3. The watch s Home Time Zone setting wi change automaticay to 9.0 whenever the battery drops to Leve 3. With this Home Time Zone setting, the watch is configured to receive the time caibration signas of Japan. If you are using the watch in North America, you wi need to change the Home Time Zone setting to match your ocation whenever the battery drops to Leve 3. Leaving the watch in direct sunight or some other very strong ight source can cause the battery power indication to show a reading that momentariy is higher than the actua battery eve. The correct battery power indication shoud appear after a few minutes. Charging Precautions Certain charging conditions can cause the watch to become very hot. Avoid eaving the watch in the areas described beow whenever charging its rechargeabe battery. Warning! Leaving the watch in bright ight to charge its rechargeabe battery can cause it to become quite hot. Take care when handing the watch to avoid burn injury. The watch can become particuary hot when exposed to the foowing conditions for ong periods.

5 Reference This section contains more detaied and technica information about watch operation. It aso contains important precautions and notes about the various features and functions of this watch. Power Saving Power Saving enters a seep state automaticay whenever the watch is eft for a certain period in an area where it is dark. The tabe beow shows how watch functions are affected by Power Saving. There actuay are two seep state eves: second hand seep and function seep. Eapsed Time in Dark Operation 60 to 70 minutes is stopped and dispay is bank. A other (second hand seep) functions are enabed. 6 or 7 days A functions, incuding anaog timekeeping, disabed (function seep) Interna timekeeping maintained Wearing the watch inside the seeve of cothing can cause it to enter the seep state. The watch wi not enter the seep state between 6:00 AM and 9:59 PM. If the watch is aready in the seep state when 6:00 AM arrives, however, it wi remain in the seep state. To recover from the seep state Perform any one of the foowing operations. Move the watch to a we-it area. Press any button. Auto Return Features If you eave the watch in the Aarm or Hand Setting Mode for two or three minutes without performing any operation, it returns to the Timekeeping Mode automaticay. If you do not perform any operation for about two or three minutes whie a setting mode is seected, the watch wi exit the setting mode automaticay. Scroing The B button is used to change the hand setting in various setting modes. In most cases, hoding down this button wi start high-speed movement of the appicabe hand(s). High-speed movement of hands wi continue unti you press any button, or unti the moving hand(s) finishes one compete cyce. - One compete cyce for the hands is one revoution (360 degrees) or 24 hours. Under certain conditions, iumination may not turn on unti about one second after you turn the face of the watch towards you. This does not necessariy indicate mafunction of the auto ight switch. You may notice a very faint cicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanica operation of the auto ight switch, and does not indicate a probem with the watch. Tachymeter Tachymeter beze If your watch has a tachymeter beze, you can perform the steps beow to cacuate average speed after using the 60 Mode to measure the amount of time that it takes to trave one kiometer (or one mie). Never try to perform stopwatch operations whie you are driving an automobie, riding a bicyce, or operating any type of vehice. Doing so is very dangerous and can resut in accident. 1 In the Mode, start an eapsed time operation at any point you ike. 2 Stop the eapsed time operation after you trave one kiometer or one mie. 3 Your average speed wi be the vaue that the second hand is pointing to on the tachymeter beze. The iustration shows an exampe where it took 50 seconds to trave one kiometer by car. The second hand is pointing at 70, which indicates that the average speed is 70 kiometers per hour. See for detais about using the stopwatch. The tachymeter can be used ony when you are traveing by car or some other means that can cover one kiometer or one mie within 60 seconds TACHYMETER Radio-controed Atomic Timekeeping Precautions Strong eectrostatic charge can resut in the wrong time being set. The time caibration signa bounces off the ionosphere. Because of this, such factors as changes in the refectivity of the ionosphere, as we as movement of the ionosphere to higher atitudes due to seasona atmospheric changes or the time of day may change the reception range of the signa and make reception temporariy impossibe. Even if the time caibration signa is received propery, certain conditions can cause the time setting to be off by up to one second. The current time setting in accordance with the time caibration signa takes priority over any time settings you make manuay. The watch is designed to update the date and day of the week automaticay for the period January 1, 2000 to December 31, Setting of the date by the time caibration signa wi not be performed starting from January 1, This watch can receive signas that differentiate between eap years and non-eap years. Though this watch is designed to receive both time data (hour, minutes, seconds) and date data (year, month, day), certain signa conditions can imit reception to time data ony. If you are in an area where proper time caibration signa reception is impossibe, the watch keeps time within ±20 seconds a month at norma temperature. If you have probems with proper time caibration signa reception or if the time setting is wrong after signa reception, check your current Home Time Zone, and DST (summer time). Timekeeping The year can be set in the range of 2000 to The watch s buit-in fu automatic caendar makes aowances for different month engths and eap years. Once you set the date, there shoud be no reason to change it except when battery power drops to Leve 3. The date wi change automaticay when the current time reaches midnight. The date change at the end of the month may take more time than norma. The current time for a time zones in the Timekeeping Mode and Dua Time Mode is cacuated in accordance with the Greenwich Mean Time (GMT) differentia of each zone, based on your Home Time Zone time setting. GMT differentia is cacuated by this watch based on Universa Time Coordinated (UTC*) data. * UTC is the word-wide scientific standard of timekeeping. It is based upon carefuy maintained atomic (cesium) cocks that keep time accuratey 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, Engand. Iumination Precautions The iumination provided by the ight may be hard to see when viewed under direct sunight. Iumination turns off automaticay whenever an aarm sounds. Frequent use of iumination shortens the battery operating time. Auto ight switch precautions 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 ight switch and iuminate the face of the watch. To avoid running down the battery, turn off the auto ight switch whenever engaging in activities that might cause frequent iumination of the face. Note that wearing the watch under your seeve whie the auto ight switch is turned on can cause frequent iumination of the face and can run down the battery. More than 15 degrees too high Iumination may not turn on if the face of the watch is more than 15 degrees above or beow parae. Make sure that the back of your hand is parae to the ground. Iumination turns off in about one second, even if you keep the watch pointed towards your face. Static eectricity or magnetic force can interfere with proper operation of the auto ight switch. If iumination does not turn on, try moving the watch back to the starting position (parae with the ground) and then tit it back towards your face again. If this does not work, drop your arm a the way down so it hangs at your side, and then bring it back up again. 5
