Receiving indicator

Operation Guide 2607 2637 2687

To perform manual time calibration signal reception

1. Place the watch on a stable surface so its top (12 o'clock side) is facing towards a window.

2. In the Timekeeping Mode, hold down Dfor 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 Level 4 receiving indicator indicates that the time calibration reception attempt was successful.

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.

About the Receiving Indicator

The receiving 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.

Strong

(Level 1)

(Level 4)

•Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receiving indicator to indicate signal strength.

•Use the receiving indicator as a guide for checking signal strength and for finding the best location for the watch during signal receive operations.

•Following reception of the time calibration signal and calibration of the watch’s time setting, the Level 4 receiving indicator will remain on the display in all modes. The Level 4 receiving indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

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, 3:00 AM, 4:00 AM, and 5:00 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) or 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 Level 4 receiving indicator indicates that either the 2:00 AM, 3:00 AM, 4:00 AM or

5:00 AM calibration signal reception was successful. Note, however, that the Level 4

receiving indicator is cleared from the display at 3:00 AM each day.

•The auto receive setting is used for time calibration signal reception only. See “About Auto Receive” for details.

•See “City Code Table” for a complete list of available city codes.

•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.

World Time

• If you do not see the Level 4 receiving 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 Level 4 receiving indicator is displayed only when the watch is able to

successfully receive both time and date data. It does not appear when only time data

is received.

• 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.

• When auto receive is turned on, the watch receives the calibration signal for two to

World Time shows the current time in 30 cities (29 time zones) around the world.

•For full information on city codes, see the “City Code Table”.

•The current time for all city codes in the 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.

4:00 AM, and 5:00 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, 3:00 AM, 4:00 AM, and 5:00 AM, regardless of whether or not the

Timekeeping Mode time is actually the correct time.

• When two, three, or four 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

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

2. Press C twice to move the flashing to the auto receive on/off setting.

3. Press Dto toggle auto receive on (ON) and off (OFF).

• If the current Home City setting is a city code that does not support signal receive, “xx” appears in place of the on/off indicator. This means you cannot turn auto receive on or off.

4. Press Atwice to exit the setting screen.

•For information about city codes that support signal receive, see “To set up the watch for use in Western Europe”.

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.

2.Hold down Ato toggle Daylight Saving Time (DST

indicator displayed) and Standard Time (DST indicator not displayed).

•The DST indicator is on the display whenever you display a city code for which Daylight Saving Time is turned on.

•Note that the DST/Standard Time setting affects only the currently displayed city code. Other city codes are not affected.

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

•The watch will perform a signal receive operation even if it is in the World Time Mode when a calibration time is reached. If this happens, the World Time Mode time settings will be adjusted in accordance with the Home City time.
