The first thing you should do after purchasing this watch is to set your Home City, which is the city where you will use the watch normally. For more information, see “To set your Home City” below.
When using the watch outside of the range of the transmitter in Fort Collins, you need to adjust the time manually as required. See “Timekeeping” for information about manual settings.

City code
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.
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 from Fort Collins, Colorado (USA). Reception is possible within North America*.
The term “North America” in this User’s Guide refers to the
*
area that consists of Canada, the continental United States, and Mexico.
Current Time Setting
This watch adjusts its time setting automatically in accordance with a time calibration signal. You can also perform a manual procedure to set the time and date, when necessary.
1. In the Timekeeping Mode, hold down A until the city
code starts to flash, which indicates the setting screen.
2. Use D(east) and B(west) to select the city code you
want to use as your Home City.
The following are the city codes for major cities in

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 automatically picks up the time calibration signal three times a day at midnight, 1:00 a.m., and 2:00 a.m. 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. 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
Inside a vehicle
Near household appliances or 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

Signal reception is normally better at night than during the day.
Time calibration signal reception takes from two to six minutes. Take care that you
do not perform any button operations or move the watch during this time.
600 miles
Under good reception conditions, 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 600 miles (1,000 kilometers) from the transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception.
See the information under “Signal Receive Troubleshooting if you experience problems with time calibration signal reception.
About Auto Receive
When auto receive is turned on, the watch starts to receive the time calibration signal automatically when the time in the Timekeeping Mode reaches midnight, 1:00 a.m. and 2:00 a.m. (calibration times). If both the 1 oclock and 2 oclock signal receptions are not successful, the watch will try to receive the signal again at the top of each hour up until 5:00 a.m. or until one more reception is successful.
Note
Auto receive works only while the watch is in the Timekeeping Mode or World Time Mode. Auto receive is not performed if an auto receive time is reached while an alarm is sounding, while a countdown timer operation is in progress, or if a setting screen (a screen with a flashing setting) is 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 receive the signal easily.
When auto receive is turned on, the watch receives the calibration signal for two to six minutes everyday when the Timekeeping Mode time reaches each of the calibration times. Do not perform any button operation within six minutes before or after any one of 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 any one of the calibration times, regardless of whether or not the Timekeeping Mode time is actually the correct time.
If more than one auto receive is successful, the watch uses the data from the last successful receive to adjust settings. 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.
Receiving indicator
Weak
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.
The Level 4 receiving 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 Level 4 receiving indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 4 receiving indicator is cleared from the display at 1:00 a.m. each day.
