Current Time Setting
This watch automatically adjusts its time setting in accordance with a time calibration signal. You can also perform a manual procedure to set the time and date, when necessary.
• The first thing you should do after purchasing this watch is to set your Home City, which is the city where you will normally use the watch. For more information, see “To set your Home City” below.
• When using the watch outside the ranges of the time signal transmitter, you have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time setting.
• The analog time of this watch is synchronized with the digital time. Because of this, the analog time setting is automatically adjusted whenever you change the digital setting. See “Analog Timekeeping” for more information.
To set your Home City
3. Press A to exit the setting screen.
• Normally, your watch should show the correct time as soon as you select your Home City Code. If it does not, it should adjust automatically after the next auto receive (in the middle of the night). You can also perform manual receive or you can set the time manually.
• If you are in an area that does not use Daylight Saving Time (summer time), turn off the DST setting.
This watch receives a time calibration signal and updates its time setting accordingly. The time calibration signal includes both Standard Time and Daylight Saving Time (summer time) data.
• This watch is designed to pick up the time calibration signal transmitted in the United States (Fort Collins, Colorado) and the time calibration signals transmitted in Japan.
• The U.S. time calibration signal can be picked up by the watch while in North America
The term “North America” in this manual refers to the
*
area that consists of Canada, the continental United States, and Mexico.

Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal: auto receive and manual receive.
• Auto Receive
With auto receive, the watch receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. For more information, see “About Auto Receive”.
• Manual Receive
Manual receive lets you start a time calibration signal reception with the press of a button. For more information, see “To perform manual receive”.
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. Make sure there are no metal objects nearby.
• The watch should not be on its side or facing the wrong way.
• Proper signal reception can be difficult or even impossible under the conditions listed
below.
Inside or among buildings
• 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 button operations or move the watch during this time.

• At distances further than about 600 miles (1,000 kilometers) from the Fort Collins (the United States) transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception.
• At distances further than about 500 kilometers (310 miles) from the Fukushima and Fukuoka/ Saga (Japan) transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception.
• Even when the watch is within the reception range of the transmitter, signal reception will be 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
• See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.
About Auto Receive
The watch receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. The reception schedule (calibration times) depends on your currently selected Home City, and whether standard time or Daylight Saving Time is selected for your Home City.

Note
• The display of the watch is blank while an auto receive operation is in progress.
• 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).
• 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 six calibration times. Do not perform any button operation within seven minutes before or after any of the six calibration times. Doing so can interfere with correct calibration
• Remember that reception of the calibration signal depends on the time kept in the digital display. Reception will be performed whenever the display shows one of the six correct time.
•
Calibration signal reception is disabled while a countdown timer operation is in progress
To perform manual receive
• Time calibration signal reception normally takes from two to seven 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 reception is unsuccessful, the message

About the Receiving Indicator (Manual receive)
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.
Weak
(Level 0)
Receiving indicator
• 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 3 receiving indicator remains on the display in all modes following reception of the time calibration signal and calibration of the watch’s time setting. The Level 3 receiving indicator is not displayed if signal reception was unsuccessful or after manual adjustment of the current time setting.
• The Level 3 receiving indicator indicates that at least one of the six calibration signal receive operations was successful. Note, however, that the Level 3 receiving indicator is cleared from the display at 0:00 a.m. each day.
