E-49 Power Supply This watch is equipped with a solar panel and a special rechargeable battery (secondary battery) that is charged by the electrical power produced by the solar panel. The illustration shown below shows how you should position the watch for charging. 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 effi ciency drops when any part of the solar panel is blocked by clothing, etc. • You should try to keep the watch outside of your sleeve as much as possible. Charging is reduced signifi cantly if the face is even only partially covered. Solar panel

E-50 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. Be 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 panel, 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 5 (CHG) (page E-51) and when you have the battery replaced. • Turn on the watch’s Power Saving function (page E-68) 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. E-51 Battery Power Indicator and Power Recovery Mode indicator The battery power indicator indicates you the current status of the rechargeable battery’s power. Battery Power indicator Level Battery Power Indicator Function Status 1 (H) All functions enabled 2 (M) All functions enabled 3 (L) (Charge Soon Alert) Auto and manual receive, illumination, and beeper disabled 4 (CHG) Except for timekeeping, all functions and display indicators disabled 5 (CHG) All functions disabled E-52 • The fl ashing LOW indicator at Level 3 (L) tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible. • At Level 5 (CHG), all functions are disabled and settings return to their initial factory defaults. Once the battery reaches Level 2 (M) after falling to Level 5 (CHG), reconfi gure the current time, date, and other settings. • Display indicators reappear as soon as the battery is charged from Level 5 (CHG) to Level 2 (M). • The watch’s Home City code setting will change automatically to TYO (Tokyo) whenever the battery drops to Level 5 (CHG). With this Home City code setting, the watch is confi gured to receive the time calibration signals of Japan. If you are using the watch in North America or Europe, or China you will need to change the Home City code setting to match your location whenever the battery drops to Level 5 (CHG). • Leaving the watch exposed to direct sunlight or some other very strong light source can cause the battery power indicator to show a reading temporarily that is higher than the actual battery level. The correct battery level should be indicated after a few minutes. E-53 • Overuse of display illumination or the beeper can cause the R (Recover) indicator to appear in the upper display, which indicates that the watch is in the battery power recovery mode. Face illumination, the alarm, the countdown timer alarm, time signals, and all hand operations are disabled in the power recovery mode. The watch continues to keep time internally, so regular timekeeping and function will resume as soon as battery power recovers to normal levels, which is indicated when the R indicator disappears. • If R appears frequently, it probably means that remaining battery power is low. Leave the watch in bright light for some time to allow it to charge. Power recovery mode indicator E-54 Charging Precautions Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable battery. Also note that allowing the watch to become very hot can cause its liquid crystal display to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature. Warning! Leaving the watch in bright light to charge its rechargeable battery can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods. • On the dashboard of a car parked in direct sunlight • Too close to an incandescent lamp • Under direct sunlight E-55 Charging Guide After a full charge, timekeeping remains enabled for up to about six months. • The following table shows the amount of time the watch needs to be exposed to light each day in order to generate enough power for normal daily operations. 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 fl uorescent lighting (500 lux) 8 hours • For details about the battery operating time and daily operating conditions, see the “Power Supply” section of the Specifi cations (page E-77). • Stable operation is promoted by frequent exposure to light.

For information about Power Saving, see “To turn Power Saving on and off” (page E-68). • Auto DST (AUTO) can be selected only while LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW, TPE, SEL, TYO, HNL, ANC, YVR, LAX, YEA, DEN, MEX, CHI, MIA, YTO, NYC, YHZ, or YYT is selected as the Home City code. For more information, see “Daylight Saving Time (DST)” below. E-61 • The day of the week is displayed automatically in accordance with the date (year, month, and day) settings. 12-hour and 24-hour timekeeping • With the 12-hour format, the PM indicator appears to the left of the hour digits 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. • The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is applied in all other modes. E-62 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 Mainfl ingen (Germany), Anthorn (England), and 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 (Daylight Saving Time) automatically in accordance with the signals. • Though the time calibration signals transmitted by the Fukushima and Fukuoka/ Saga, Japan transmitters include summer time data, summer time currently is not implemented in Japan (as of 2013). • The default DST setting is Auto DST (AUTO) whenever you select LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW, TYO, ANC, YVR, LAX, YEA, DEN, MEX, CHI, MIA, YTO, NYC, YHZ, or YYT 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. E-63 To change the Daylight Saving Time (summer time) setting 1. In the Timekeeping Mode, hold down A for about fi ve seconds, until the watch beeps twice and the city code fl ashes on the upper display. This is the setting mode. 2. Press C.

After everything is the way you want, press A to return to the Timekeeping Mode. • After you complete the home position adjustment procedure, place the watch in a location that allows for good time calibration signal reception, and then perform a manual receive operation. See “To perform manual receive” (page E-24) for more information. Correct hour and minute hand positions E-66 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. Power Saving Function When turned on, the Power Saving function enters a sleep state automatically whenever the watch is left in an area for a certain period where it is dark. The table below shows how watch functions are affected by the Power Saving function. E-67 Elapsed Time in Dark Hands and Display Operation 60 to 70 minutes Left dial hand: PS; Other hands: Normal; Display: Blank All functions enabled, except for displays 6 or 7 days Left dial hand: PS; Other hands: Stopped at 12 o’clock; Display: Blank Auto receive, beeper tone, illumination, and display disabled. • 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. • Angle the watch towards your face for reading (page E-47). E-68 To turn Power Saving on and off 1. In the Timekeeping Mode, hold down A for about fi ve seconds, until the watch beeps twice and the city code fl ashes on the upper display. This is the setting mode. 2. Press C nine times until PS appears in the upper display and a fl ashing or appears in the lower display. This is the Power Saving on/off screen. 3. Press D to toggle Power Saving on ( ) and off ( ). 4. Press A to exit the setting mode. On/Off status E-69 Radio-controlled Atomic Timekeeping Precautions • Strong electrostatic charge can cause the time setting to be thrown off. • The time calibration signal bounces off the ionosphere. Because of this, such factors as changes in the refl ectivity 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, 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.

E-70 • If you are in an area where proper time calibration signal reception is impossible, the watch keeps the time with the precision noted in “Specifi cations”. • 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, and DST (Daylight Saving Time) settings (page E-58). • The Home City setting reverts to the initial default of TYO (Tokyo) whenever the battery power drops to Level 5 (CHG) or when you have the rechargeable battery replaced. If this happens, change the Home City to the setting you want (page E-12). Transmitters The time calibration signal received by this watch depends on the currently selected Home City (page E-12). • When a U.S. time zone is selected, the watch receives the time calibration signal transmitted from the United States (Fort Collins). • When a Japanese time zone is selected, the watch receives the time calibration signals transmitted from Japan (Fukushima and Fukuoka/Saga). • When a European time zone is selected, the watch receives the time calibration signals transmitted from Germany (Mainfl ingen) and England (Anthorn). E-71 • When a China time zone is selected, the watch receives the time calibration signal transmitted from China (Shangqiu City). • When your Home City is LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW (which can receive both the Anthorn and Mainfl ingen signals), the watch fi rst tries to pick up the signal it last received successfully. If that fails, it tries the other signal. For the fi rst receive after you select your Home City, the watch tries the nearest signal fi rst (Anthorn for LIS, LON, Mainfl ingen for MAD, PAR, ROM, BER, STO, ATH, and MOW). Auto Return Features • If you leave the watch with a fl ashing setting on the display for two or three minutes without performing any operation, the watch will exit the setting mode automatically. • The watch will return to the Timekeeping Mode automatically if you do not perform any operation for two or three minutes in the Alarm Mode. 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). E-72 Initial Screens When you enter the World Time Mode or Alarm Mode, the data you were viewing when you last exited the screen will appear fi rst. Timekeeping • Resetting the seconds to 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 without changing the minutes. • 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 when battery power drops to Level 5 (CHG) (page E-51). • The current time for all city codes in the Timekeeping Mode and World Time Mode is calculated in accordance with the Coordinated Universal Time (UTC) for each city, based on your Home City time setting. E-73 Illumination Precautions • Illumination may be hard to see when viewed under direct sunlight. • 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 4 (CHG) (page E-51). • Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light switch to operate when it is not needed, which shortens battery life. If you want to wear the watch on the inside of your wrist, turn off the auto light switch feature. • 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. More than 15 degrees too high E-74 • 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 toward 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.
