Radio-controlled Atomic Timekeeping

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).
The U.S. time calibration signal can be picked up by the watch while in North America*. * The term “Nor th America” in this manual 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.
The first thing you should do after purchasing this watch is to specify your Home Time Zone, which is the time zone where you will normally use the watch. For more information, see “To specify your Home Time Zone” below.
When using the watch outside the range of the U.S. time signal transmitter, you have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.

3. Press A eight times to exit the setting mode.
The watch will also return to the Timekeeping Mode if you do not perform any operation for about two or three minutes.
Normally, your watch should show the correct time as soon as you specify your Home Time Zone. 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.
Even if the time calibration signal is received correctly, there are some times when the analog hands may not indicate the correct time. If this happens, use the procedures under “Adjusting the Home Positions” to check the home positions of the hands, and make adjustments as required.
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 9 o’clock side facing towards a window. Make sure there are no metal objects nearby.
The watch should not be facing the wrong way.

Operation Guide 3722
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 four 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.
Reception Ranges
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 Fort Collins 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 Reception Troubleshooting” if you experience problems with time calibration signal reception.
About Auto Receive
The watch automatically starts to receive the time calibration signal when the time in the Timekeeping Mode reaches 0:01 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 operations are successful. 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 Time Zone, and whether standard time or Daylight Saving Time is selected for your Home Time Zone.
Note
The auto receive operation is performed only if the watch is in the Timekeeping 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.
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.
The watch receives the calibration signal for four to seven minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Do not perform any button operation within seven 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 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 is actually the correct time.

Alarm

When the alarm is turned on, the alarm sounds when the alarm time is reached.
All of the operations in this section are performed in the
Alarm Mode, which you enter by pressing B.
When you enter the Alarm Mode, the second hand will move to either ON (alarm on) or OFF (alarm off), and the hands will move to the current alarm time setting.
To set an alarm time
1. In the Alarm Mode, hold down A for five seconds to
display the setting mode.
The second hand will move to AM or PM.
2. Use A and B to change the alarm time.
Press B to move the hands clockwise in one-minute
To move the hands back, press A. After that, each press of B will move the
hands counterclockwise in one-minute steps.
Once you use the above operation to change to counterclockwise hand
movement, pressing A will not change back to clockwise hand movement. Pressing A during counterclockwise hand movement will exit the setting mode. To use clockwise hand movement again, you will need to exit the setting mode and restart this procedure from step 1.
When setting the alarm time, take care to set AM and PM correctly. The second hand will move between AM and PM any time the hour hand moves past 12 o’clock while you are setting the alarm time.
3. After setting the alarm time, press A as many time as necessary to exit the setting
mode.
If you set the alarm time using clockwise hand movement only, press A twice to exit
the setting mode.
If you set the alarm time using counterclockwise hand movement, press A once to
exit the setting mode.
This will cause the hour and minute hands to move to the current time, and the second hand to move to ON (alarm on).
Setting the alarm time causes the alarm to turn on automatically.
