Time Calibration Signal Reception
This watch is designed to pick up a time calibration signal and update its time setting in accordance with the signal. There are two different methods you can use to receive the signal: Auto Receive and Manual Receive. With Auto Receive, the watch automatically receives the calibration signal three times each day and makes appropriate adjustments. With Manual Receive, you perform a specific button operation to receive the calibration signal. Before performing a signal receive operation, remove the watch from your wrist and position it as shown in the illustrations below.
If your watch has a resin band, pass the end of the band through the band loop and place the watch on a stable surface.
Note
If you are using the time calibration signal to set the time for this watch, be sure to correctly set your Home City. Otherwise, there is the chance that the watch will not set the correct time. See Setting the Time and Date Manually” for details.
Note that signal reception is possible only when the watch is within range of a time calibration signal transmitter, and a city code that supports signal reception is selected as the Home City code.
The current time setting in accordance with the time calibration signal takes priority over any time settings you make.
Auto receive is turned on when the watch is shipped from the factory.
See the information under Time Calibration Signal Reception if you experience
problems with time calibration signal reception.
To perform manual time calibration signal reception
1. Place the watch on a stable surface so its top (12 o'clock side) is facing in the
general direction of the signal transmitter.
Note that signal reception is poor if the watch is on its back or side.
Receive indicator
Note
To interrupt a receive operation and return to the Timekeeping Mode, press D.
If the receive operation is unsuccessful, the message ERR appears on the display
for about one or two minutes. After that, the watch returns to the Timekeeping Mode.
You can also change from the Last Signal or ERR screen to the normal timekeeping screen by pressing D.

Pass through band loop.
2. In the Timekeeping Mode, hold down D for about two
seconds until the watch beeps.
Release D and the message RC! appears to indicate
that signal reception has started.
Time calibration signal reception takes from two to six minutes. Take care that you do not move the watch during this time.
After signal reception is complete, the display of the watch changes to the Last Signal screen.
The receive indicator indicates that the time calibration reception attempt was successful.

Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receive indicator to indicate signal strength.
Use the receive indicator as a guide for checking signal strength and for finding the best location for the watch during signal receive operations.
The receive indicator remains on the display in all modes following reception of the time calibration signal and calibration of the watchs time setting. The receive indicator does not appear if signal reception was unsuccessful or after manual adjustment of the current time setting.
About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time calibration signal when the time in the Timekeeping Mode reaches 2:00 AM, 4:00 AM and 6:00 AM each day (calibration times).
Note
The auto receive operation is performed only if the watch is in the Timekeeping or World Time Mode when one of the calibration times is reached. It is not performed if a calibration time is reached while you are making settings (while settings are flashing on the display), while an alarm is sounding.
Auto receipt 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 easily receive the signal.
The receive indicator indicates that either the 2:00 AM, 4:00 AM, or 6:00 AM calibration signal reception was successful. Note, however, that the receive indicator is cleared from the display at 3:00 AM each day.
If you do not see the receive indicator except for the above reason, it means there was some problem with the calibration reception operation. Either perform reception manually, or make sure the watch is set up properly to receive the time calibration signal for the next automatic reception time.
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.
The receive indicator ( receive both time and date data. It does not appear when only time data is received. When time and date data is received: Receive indicator ( When time data only is received: Receive indicator (
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 date as kept in the Timekeeping Mode at the time of signal reception.
When auto receive is turned on, the watch receives the calibration signal for two to six minutes each day when the Timekeeping Mode time reaches 2:00 AM, 4:00 AM and 6:00 AM. Do not operate any of the watch’s buttons within six minutes prior to or following the calibration times. Doing so can interfere with correct calibration.
Remember that reception of the calibration signal depends on the time kept in the Timekeeping Mode. The receive operation will be performed whenever the display shows 2:00 AM, 4:00 AM and 6:00 AM, regardless of whether or not the Timekeeping Mode time is actually the correct time.
When two or three receptions are successful, the watch uses the data of the last reception for calibration. When only one reception is successful, the watch uses the data of the successful reception.
To turn auto receive on and off
Setting the Time and Date Manually
Make sure you select your Home City code (the city code whose time and date you are setting) before 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.

The A, 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 Alarm, Date Alert, or World Time Mode, the data you were viewing when you last exited the mode appears first.
Time Calibration Signal Reception
1,200 miles
2,000 miles
This watch is able to receive the time calibration signal transmitted from Fort Collins, Colorado. Signal reception is possible within a radius of about 2,000 miles (3,000 kilometers) from the Fort Collins transmitter.
Fort Collins

USERS 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.
Troubleshooting
Check the following points whenever you experience problems with your watch.
Problem
Cannot perform manual receive.
Auto receive is turned on, but the receive indicator does not appear on the display.
Time setting is incorrect following signal reception.
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 C three times until the summer time (DST) setting screen appears.
3. Use D to cycle through the summer time settings in the sequence shown below.
Auto DST( ) DST off( ) DST on( )
Probable Cause
The watch is not in the Timekeeping Mode.
You do not select one of the following City Codes as your Home City Code: NYC, CHI, DEN, or LAX.
You changed the time setting manually.
The watch was not in the Timekeeping
or World Time Mode, or you were performing some button operation during the auto signal receive operation was performed.
Even if receive is successful, the receive indicator disappears every day at 3am.
Time data (hour, minutes, seconds) only was received during the last receive operation. The receive indicator appears only when time data and date data (year, month, day) are both received.
If the time is one hour off, the DST setting may be incorrect.
The Home City Code setting is not correct for the area where you are using the watch.
What you should do
Enter the Timekeeping Mode and try again.
Select the correct Home City Code.
Perform manual signal receive or wait until the next auto signal receive operation is performed.
Check to make sure the watch is in a location where it can receive the signal.
Put the watch in a location that is suitable for good reception.
Change the DST setting to Auto DST.
Select the correct Home City Code.
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 B to 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.

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 watchs 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.
