Important! • Normally, your watch should show the correct time as soon as you select your Home Time Zone. 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. • The watch will receive the time calibration signal automatically from the applicable transmitter (in the middle of the night) and update its settings accordingly. For information about the relationship between time zones and transmitters, see “Home Time Zones and Transmitters”. • Under factory default settings, auto receive is turned off for all of the following time zones : UTC +8, UTC –10, and UTC –9. For details about turning on auto receive for these time zones, see “To turn auto receive on and off”. • You can disable time signal reception, if you want. See “To turn auto receive on and off” for more information. • 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 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 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”. 1 III I I III Operation Guide 4709 4713 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. This watch is designed to receive a time calibration signal late at night. Because of this, you should place the watch near a window as shown in the illustration when you take it off at night. 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 Time Zone, and whether standard time or Daylight Saving Time is selected for your Home Time Zone. Your Home Time Zone 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 a vehicle Near household appliances, office equipment, or a mobile phone Near a construction site, airport, or other sources of electrical noise Near hightension power lines Among or behind mountains • 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 Time Zone 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.

Reception is not performed if a calibration time is reached while you are configuring settings. • 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. • The watch receives the calibration signal for two to 14 minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Avoid performing 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 current time 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 displayed time actually is the correct time.

When you change the digital time setting manually When the digital time setting is changed by time calibration signal reception When you change the Home Time Zone and/or DST setting • If the analog time does not match the digital time for any reason, use the procedure described under “To adjust the analog time” to match the analog setting to the digital setting. • Whenever you need to adjust both the digital and the analog time settings manually, make sure you adjust the digital setting first. • Depending on how much the hands have to move in order to adjust to the digital time, it may take some time before they stop moving. To adjust the analog time II III III I IIII 1. In the Timekeeping Mode, press B five times to enter the Hand Setting Mode. 2. Hold down A until the current digital time starts to flash, which indicates the setting screen. 3. Use C to adjust the analog setting as described below. III I I III When you want to do this: Move the hand setting forward 10 seconds Move the hand setting a short way forward at high speed Move the hand setting a long way forward at high speed Perform this button operation: • Press C. • Hold down C. • Release C when the hands reach the setting you want. • While holding down C to move the hands at high-speed, press B to lock the high-speed hand movement. • To stop the hand movement, press any button. • Hand movement stops automatically if the hour hand makes one full (12-hour) revolution. 4. Press A to exit the setting screen. • The minute hand will be adjusted slightly to match the seconds when you exit the setting screen. • To return to the Timekeeping Mode, press B. Scrolling C is used in various modes and setting screens to scroll through data. In most cases, holding down C during a scroll operation scrolls through the data at high speed. Initial Screens When you enter the Dual Time or Alarm Mode, the data you were viewing when you last exited the mode appears first. 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 a 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 with the precision noted in “Specifications”. • If you have problems with proper time calibration signal reception or if the time setting is wrong after signal reception, check your current time zone, DST (summer time), and auto receive settings. 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 5. • The times for the Timekeeping Mode and all the time zones of the Dual Time Mode are calculated in accordance with each time zones UTC differential. • The UTC differential is a value that indicates the time difference between a reference point in Greenwich, England and the time zone. • The letters “UTC” is the abbreviation for “Universal Time Coordinated”, which 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. 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 • 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.

It also contains important precautions and notes about the various features and functions of this watch. Power Saving Function 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. Approximate Period Functions in sleep state 4 to 7 days • LCD off • Alarm, hourly time signal, analog timekeeping and auto receive enabled 8 days or more • LCD off, alarm and hourly time signal disabled • Analog timekeeping stopped at 12 o’clock • Auto receive disabled The sleep state is indicated by a blank screen. • Wearing the watch inside the sleeve of clothing can cause it to enter 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. Auto Return Features • If you leave the watch in the Alarm Mode or Hand Setting Mode, or with the Battery Level indicator displayed for two or three minutes without performing any operation, it returns to the Timekeeping Mode automatically. • If you leave the watch with the Last signal screen displayed for one or two minutes without performing any operation, it returns to the Timekeeping Mode automatically. • If you leave the watch with a flashing setting on the display for two or three minutes without performing any operation, the watch exits the setting screen automatically.
