Important!
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 operation (in the middle of the night). You can also perform manual receive or you can set the time manually.
The watch will receive the time calibration signal automatically from the applicable transmitter (in the middle of the night) and update its settings accordingly. For information about the relationship between city codes and transmitters, see “Home City Codes and Transmitters”.
Under factory default settings, auto receive is turned off for all of the following city codes: MOW (Moscow), HKG (Hong Kong), BJS (Beijing), HNL (Honolulu), and ANC (Anchorage). For details about turning on auto receive for these city codes, see “To turn auto receive on and off”.
You can disable time signal reception, if you want. See “To turn auto receive on and off” for more information.
See the maps under “Approximate Reception Ranges” for information about the reception ranges of the watch.
If you are in an area that does not use Daylight Saving Time (summertime), turn off the DST setting.
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 receive operation 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. 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.

Operation Guide 3107
Proper signal reception can be difficult or even impossible under the conditions listed below.
Inside or among buildings
Signal reception normally is 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.
The time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below. If you use the watch in Japan or Europe (each of which has two different transmitter locations), it will try to receive the time calibration signal from one of the transmitters in your current location. If it cannot receive the signal, it will then try to receive the time calibration signal from the other transmitter.
Inside a vehicle
Near household appliances, office equipment, or a mobile phone
Near a construction site, airport, or other sources of electrical noise
Near high­tension power lines
Among or behind mountains

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
When a calibration time is reached, the watch will receive the calibration signal only if it is in either the Timekeeping Mode or World Time Mode. Reception is not performed if a calibration time is reached while you are configuring settings.
Auto receive 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 receive the signal easily.
Remember that reception of the calibration signal depends on the current time in the Timekeeping Mode. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time actually is the correct time.
Calibration signal reception is disabled while a countdown timer operation is
in progress.
About the Signal Strength Indicator
The signal strength 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. The signal strength indicator is displayed while an auto or manual receive operation is in progress.
Settings updated indicator
Weak
(Level 0)
Signal strength 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 signal strength 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 settings updated indicator will remain on the display in all modes. The settings updated indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.
The settings updated indicator is displayed only when the watch is able to receive both time and date data successfully. It does not appear when only time data is received.
The settings updated indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the settings updated indicator disappears from the display each day when the first auto receive operation of the day is performed.
