To recover from the sleep state

Perform any one of the following operations.

•Move the watch to a well-lit area.

•Press any button.

On/Off status

Auto Return Features

•If you leave the watch in the Alarm Mode for two or three 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.

Scrolling

The B and D buttons are used in various modes and setting screens to scroll through data. 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 or Alarm 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.

•Even when the watch is within the reception range of the transmitter, signal reception is 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.

•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 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 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 within ±15 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. The following are the initial factory defaults for these settings.

Transmitters

This watch is designed to receive the time calibration signal transmitted from Rugby, England and the signal from Mainflingen, Germany. You can configure the watch to automatically select the transmitter that has the strongest signal.

Module 2972

In this case:

The watch does this:

The first signal auto search operation

1. Checks the Rugby signal first.

after factory default settings are in effect,

2. If the Rugby signal cannot be received,

or after the city code has been changed

checks the Mainflingen signal.

Any case other than the above.

1. Checks the last successfully received

 

signal first.

 

2. If the last successfully received signal

 

cannot be received, checks the other

 

signal.

 

 

Module 2973

 

 

 

In this case:

The watch does this:

The first signal auto search operation

1. Checks the Mainflingen signal first.

after factory default settings are in effect,

2. If the Mainflingen signal cannot be

or after the city code has been changed

received, checks the Rugby signal.

Any case other than the above.

1. Checks the last successfully received

 

signal first.

 

2. If the last successfully received signal

 

cannot be received, checks the other

 

signal.

 

 

•Auto receive is turned on whenever the transmitter mode is qvtA , DCF, or MSF, Auto receive is turned off when the transmitter mode setting is OFF.

•Note that you can change the transmitter mode setting when LON, PAR, BER, or ATH is selected as the Home City code.

•See “To select the transmitter mode” below.

To select the transmitter mode

 

 

 

1. In the Timekeeping Mode, press D to display the last

 

signal screen.

 

 

 

 

2. Hold down A until the transmitter mode setting starts

 

 

 

 

 

 

 

 

 

 

to flash, which indicates the setting screen.

 

 

 

 

 

 

 

 

 

• If holding down Adoes not display the setting

 

 

 

 

screen, check the current Home City code setting.

 

 

 

 

 

Press D to return to the Timekeeping Mode screen and then refer to “To set your Home City” for information about city codes that support signal reception.

3. Press Dto select the transmitter mode setting you want to use.

• The following are the available transmitter mode settings. qvtA: Automatic selection of the Mainflingen or Rugby signal DCF: Reception of the Mainflingen signal

MSF: Reception of the Rugby signal

OFF: Auto receive off

4. Press Ato exit the setting screen and return to the last signal screen.

•If you want to the return to the Timekeeping Mode screen, press D.

•Signal reception can take up to 12 minutes when the qvtA option is selected.

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 4.

•The current time for all city codes in the Timekeeping Mode and World Time Mode is calculated in accordance with the Greenwich Mean Time (GMT) differential for each city, based on your Home City time setting.

•GMT differential is calculated by this watch based on Universal Time Coordinated

(UTC*) data.

*UTC 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. The reference point for UTC is Greenwich, England.

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

•The electro-luminescent panel that provides illumination loses power after very long use.

•Illumination may be hard to see when viewed under direct sunlight.

•The watch may emit an audible sound whenever the display is illuminated. This is due to vibration of the EL panel used for illumination, and does not indicate malfunction.

•Illumination turns off automatically whenever an alarm sounds.

•Frequent use of illumination runs down the battery.
