Setting the Digital Time and Date Manually

Make sure you select your Home City code before you change the current time and date settings. World Time Mode times are all displayed in accordance with the Timekeeping Mode settings. Because of this, World Time Mode times will not be correct if you do not select the proper Home City code before setting the time and date in the Timekeeping Mode.

To set the current digital time and date manually

1.In the Timekeeping Mode, hold down Auntil the transmitter indicator starts to flash, which indicates the setting screen.

2.Use Aor C to move the flashing in the sequence shown below to select other settings.

4. Use A to exit the setting screen.

•If a Transmitter/City Setting screen is displayed, press A twice.

•If a Time/Date Setting screen is displayed, press Aonce.

•When you exit the setting screen, the analog hands are adjusted automatically to match the digital time. See “Analog Timekeeping” for more information.

Note

•See “Transmitters” for more information.

•Auto DST (A) can be selected only while BER, PAR, LON, or ATH 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.

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 Rugby and Mainflingen include 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 (A) whenever you select BER, PAR, LON, or ATH as your Home City code.

•If you experience problems receiving the time calibration signal in your area, it is probably 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 Auntil transmitter indicator starts to flash, which indicates the setting screen.

2.Press Ctwice and the DST setting screen appears.

3.Use D to cycle through the DST settings in the sequence shown below.

Auto DST (A) DST off (OFF) DST on (ON)

4. When the setting you want is selected, press Atwice to exit the setting screen.

Analog Timekeeping

The analog time of this watch is synchronized with the digital time. The analog time setting is adjusted automatically whenever you change the digital time.

Note

•The hands for the analog timepiece move to adjust to a new setting whenever any of the following occurs.

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 City code 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 the analog hands stop moving.

To adjust the analog time

1.In the Timekeeping Mode, press Csix times to enter the Hand Setting Mode.

2.Hold down Auntil the current digital time starts to flash, which indicates the setting screen.

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.

Auto return features

•If you leave the watch in the Alarm (except for the target alarm screen explained on “To set an alarm time”), Date Alert, or Hand Setting Mode for two or three minutes without performing any operation, it automatically changes to the Timekeeping Mode.

•If you leave the watch with a flashing setting or cursor on the display for two or three minutes without performing any operation, it automatically saves any settings you have made up to that point and exits the setting screen.

Scrolling

The Band 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, Alarm, or Date Alert Mode, the data you were viewing when you last exited the mode appears first.

Radio-controlled 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 automatically update the date and day of the week for the period January 1, 2000 to December 31, 2039. Setting of the date by the time calibration signal cannot be performed starting from January 1, 2040.

•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.
