Important!
•When getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 12 o’clock side facing towards a window. This watch is designed to receive a time calibration signal late at night. Because of this, you should place the watch near a window as shown in the illustration when you take it off at night. Make sure there are no metal objects nearby.

• Signal reception is normally better at night than during the day. |
• Time calibration signal reception takes from two to seven minutes, but in some |
cases it can take as long as 14 minutes. Take care that you do not perform any |
•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 reception.
•The Level 4 receiving indicator appears on the Timekeeping Mode’s Receiving Indicator and Seconds Count screen only. The Level 4 receiving indicator is not displayed if signal reception was unsuccessful or after manual adjustment of the current time setting.
•The Level 4 receiving indicator indicates that at least one of the five calibration signal reception was successful. Note, however, that the Level 4 receiving indicator is cleared from the display at 3:00 a.m. each day.
To perform manual receive
1. Place the watch on a stable surface so its top (12 o’clock side) is facing towards a window.

• Time calibration signal reception normally takes from two to seven minutes, but in some cases it can take as long as 14 minutes. Take care that you do not perform any button operations or move the watch during this time.
• After signal reception is complete, the display of the watch changes to the last signal screen.
Note
•To interrupt a reception and return to the Timekeeping Mode, press D.
•If the reception 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.

500 kilometers | range as of April 2007 |
•In April 2007, the U.K. signal transmitter was moved from Rugby to Anthorn, which resulted in a slight shift in the approximate reception range of the signal. The shift is so slight that there is virtually no change in the ability to receive the signal.
•Even when the watch is within the reception range of a transmitter, signal reception may be impossible at times due to the effects of geographic contours, structures, weather, the season of the year, the time of day, radio interference, etc. Note that the signal becomes weaker at distances of approximately 500 kilometers from the transmitter, which means that the influence of the conditions listed above becomes even greater.
•See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.
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 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will also perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled auto receive are successful.
Note
• Auto receive is performed only if the watch is in the Timekeeping Mode or World |
Time Mode when one of the calibration times is reached. It is not performed if a |
calibration time is reached while an alarm is sounding, or while you are configuring |
settings (while settings are flashing on the display). |
• When a reception starts, the second hand will move at high speed to the 12 o’clock |
position where it will stop until the reception is complete. |
• 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. |
• When auto receive is turned on, the watch receives the calibration signal for two to |
seven minutes everyday when the time in the Timekeeping Mode reaches each of |
the five calibration times. Do not perform any button operation within seven minutes |
before or after any of the five calibration times. Doing so can interfere with correct |
calibration. |
•The second hand will advance at high speed to the correct position in accordance with the digital time seconds count, and resume normal movement from there.
•For information about city codes that support signal reception, see “To set your Home City”.

• Remember that reception of the calibration signal depends on the time kept in the |
digital display. The reception will be performed whenever the display shows one of |
the five calibration times, regardless of whether or not the displayed time is actually |
the correct time. |
• When two, three, four, or five 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. |
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.

City Code
Current time in the selected city code
The World Time Mode digitally displays the current time in 30 cities (29 time zones) around the world.
•Pressing A in the World Time Mode causes the applicable city code to appear on the digital display for about two seconds.
•If the current time shown for a city is wrong, check your Home City time settings and make the necessary changes.
•The watch will perform a signal reception 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 Timekeeping Mode’s Home City time.
•All of the operations in this section are performed in the World Time Mode, which you enter by pressing C.
