USER’S GUIDE 2556

General Precautions

•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.

•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.

•Reception is best when the antenna built into the 12 o'clock edge of the watch is facing in the general direction of the signal transmitter. Note, however, that moving the watch while the time calibration signal receive operation is taking place will make stable reception impossible.

•Think of the watch as acting like a TV or radio when it is receiving the calibration signal. When receiving indoors, move to a location as near as possible to a window.

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

Near TVs, refrigerators, computers, or other household appliances

Far away from broadcasting stations among ferro-concrete structures or near mountains

Underground, in tunnels or in ferro-concrete buildings

Near high-tension wires, neon signs, or radio stations with interfering frequencies Near railroads, highways or airports

In trains or cars

•Radio interference can make signal reception impossible.

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

Auto Summer Time (DST) Switching

The time calibration signal transmitted from Fort Collins, Colorado includes both standard time and summer time (Daylight Saving Time) data. When auto summer time (DST) switching is turned on, the watch switches between standard time and summer time (DST) automatically in accordance with the Fort Collins signal.

•Daylight Saving Time (DST) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time.

•When using the watch in the Continental United States, select Auto DST for the auto summer time setting.

•The default auto summer time settings is Auto DST whenever you select one of the following city codes as your Home City code: NYC, CHI, DEN, LAX, ANC, or HNL.

•If you experience problems receiving the time calibration signal in your area, it is probably best to turn off auto time switching.

To select the auto summer time setting

1.In the Timekeeping Mode, hold down A until the current auto receive on/off setting to flash, which indicates the setting screen.

2.Press Cthree times until the summer time (DST) setting screen appears.

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

Timekeeping

•The day of the week is automatically displayed in accordance with the date (year, month, and day) settings.

•The year can be set in the range of 2000 to 2039.

•The watch’s built-in full automatic calendar automatically 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.

•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 the your Home City time setting.

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

(UTC*) data.

*The letters “UTC” stands for “Universal Time Coordinated,” which is the world-wide scientific standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks that keep accurate 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 (except for the World Time Mode and Time Recorder Mode).

•With the 12-hour format, the P (PM) indicator appears on the display for times in the range of noon to 11:59 p.m. and the 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, with 24 indicator.

•The Word Time Mode and Time Recorder Mode always display times using 24-hour format, regardless of the 12-hour/24-hour format setting in the Timekeeping Mode.

•In all modes besides the Timekeeping Mode, the current Home City time in the upper left corner of the display is always displayed using 24-hour format.

Backlight Precautions

The backlight uses an EL (electro-luminescent) panel that causes the entire display to glow for easy reading in the dark.

In any mode, press Bto illuminate the display for about one second.

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

•The illumination provided by the backlight 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.

•The backlight automatically turns off whenever an alarm sounds.

•Frequent use of the backlight shortens the battery life.
