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 also can 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 city codes and transmitters, see “Home City Codes and Transmitters”.

• Under factory default settings, auto receive is turned off for all of the following city codes: MOW (Moscow), HKG (Hong Kong), BJS (Beijing), and HNL (Honolulu). For details about turning on auto receive for these city codes, 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 (summertime), turn off the DST setting.

This watch receives a time calibration signal and updates its time setting accordingly.

• Supported time calibration signals: Germany (Mainflingen), England (Anthorn), United States (Fort Collins), Japan.

Current Time Setting

This watch adjusts its time setting automatically in accordance with a time calibration signal. You also can perform a manual procedure to set the time and date, when necessary.

• The first thing you should do after purchasing this watch is to specify your Home City (the city where you normally will use the watch). For more information, see “To specify your Home City”.

1. In the Timekeeping Mode, hold down A until the city

code starts to flash. This is the setting screen.

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”.

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.

• Make sure the watch is facing the right way.

• Proper signal reception can be difficult or even impossible under the conditions

described below.

Inside or among buildings

• 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 City code 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.

• Even when the watch is within the reception range of the transmitter, signal reception will be 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 Reception Troubleshooting” if you experience problems with time calibration signal reception.

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 City, and whether standard time or Daylight Saving Time is selected for your Home City.

• The display of the watch is blank while an auto receive operation is in progress.

Note

• When a calibration time is reached, the watch will receive the calibration signal only if it is in either the Timekeeping Mode or World Time Mode. 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 seven minutes every day when the time in the Timekeeping Mode reaches each of the calibration times. Avoid performing any button operation within seven 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.

• Calibration signal reception is disabled while a countdown timer operation is

in progress.

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.

• Use the receiving indicator as a guide for checking signal strength and for finding the best location for the watch during signal receive operations.

• Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receiving indicator to indicate signal strength.

Auto Return Features

• If you leave the watch in the Alarm or Hand Setting Mode for two or three minutes without performing any operation, it will return 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 will exit 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.

Initial Screens

When you enter the World Time Mode, the data you were viewing when you last exited the mode will appear first.

Radio-controlled Atomic Timekeeping Precautions

• Strong electrostatic charge can result in the wrong time being set.

• The time calibration signal bounces 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 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.

• 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 will show 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 ±30 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.
