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 you 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.

USER’S GUIDE 2709

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.

• 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.

• Time calibration signal reception is disabled while the analog hands are moving after

you change the digital time setting.

• 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.

2. In the Timekeeping Mode, hold down A for about two

seconds until the watch beeps.

• Release A and the message receiving 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, and the analog time of the watch is adjusted automatically.

Receive indicator

Note

• To interrupt a receive operation and return to the Timekeeping Mode, press A.

• If the receive operation is unsuccessful, the message ERROR! 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 ERROR! screen to the normal

timekeeping screen by pressing A.

About the Receive Indicator

The receive 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.

Weak

• 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 watch’s 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 digital 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, or while a silent alert operation is being performed.

• Auto receipt of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the digital 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.

• When auto receive is turned on, the watch receives the calibration signal for two to six minutes each day when the digital 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 shown on the digital display. The receive operation will be performed whenever the digital display shows 2:00 AM, 4:00 AM and 6:00 AM, regardless of whether or not the displayed 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 Digital 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.

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, Data Memory, or Hand Setting Mode for two or three minutes without performing any operation, it automatically changes to the Timekeeping Mode.

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

Data and Setting Scrolling

The A 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 or World Time Mode, the data you were viewing when you last exited the mode appears first.

Time Calibration Signal Reception

• This watch is designed to receive a time calibration signal originating from one of the three transmitters listed below.

Location

Call Sign

Fort Collins, Colorado

Fukushima, Japan

Fukuoka/Saga, Japan

• When you select one of the city codes shown below as your Home City code, the watch sets up automatically to receive from the applicable transmitter. Time calibration signal reception is not possible whenever any other city code is specified as the Home City code.

• When you select TYO as your Home City code, the watch automatically selects either the Fukushima signal (40kHz) or the Fukuoka/Saga signal (60kHz), depending on which is stronger.

Home City Code

LAX, DEN, CHI, NYC

TYO

• Note that when TYO (Japan) is selected as the Home City code, you can specify one of two different time signal transmitters.

1,200 miles

• Signal reception is possible within a radius of about 2,000 miles (3,000 kilometers) from the Fort Collins transmitter.

• At distances further than about 500 kilometers from the Fukushima and Fukuoka/ Saga transmitter, the signal may become weak and reception may be impossible under certain conditions.

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. Place the watch near a window in a location where there are no nearby

metal objects.

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

Inside or among buildings

• Do not move the watch or operate any of its buttons while signal reception is being performed.

• This watch automatically receives a time calibration signal in the middle of the night, when reception is best.

• Radio interference can make signal reception impossible.

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

• 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.

Troubleshooting

Check the following points whenever you experience problems with your watch.

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.

• The time calibration signals transmitted from the Fukushima and Fukuoka/Saga do not include summer time data.

• When using the watch in the Continental United States or in Japan, 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: HKG, TYO, SEL, 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.

1. In the Timekeeping Mode, press B. This causes the current auto receive on/off

setting (the receive indicator) 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.

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

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 batter y replaced.

• The current time for all city codes in the Timekeeping 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.

• 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.

Screen

• You can input Japanese phonetic characters (katakana), alpha characters, symbols, and numbers in the text area. For a complete list of characters you can input, see the “Character List”.

2. When the character you want is at the cursor position, press C to move the cursor

to the right.

3. Repeat steps 1 and 2 to input the rest of the characters you want.

Data Memory Management

Data memory can hold up to 315 characters total, while each record can contain up to 63 characters. This means that 40 records can be stored in data memor y when each record contains seven characters of text or less.

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 L 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.

1. When the cursor is on the display, use A and D to

cycle through the available letters, numbers and symbols, in the sequence shown below.

Press D.
