•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.

•The time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below.

•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.

Your City Code			Auto Receive Start Times
		1	2	3	4	5	6
TYO (GMT +9)	Standard Time	Midnight	1:00 am	2:00 am	3:00 am	4:00 am	5:00 am

Note

•Auto receive is supported in all modes except while a stopwatch elapsed time operation is in progress.

•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 two to 14 minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Do not perform any button operation within ten 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.

To perform manual receive

		1. Place the watch on a stable surface so its 12 o’clock
		side is facing towards a window.
		2. In the Timekeeping Mode, hold down Afor about two
		seconds until the watch beeps.
		3. The stopwatch second hand will move to READY to
		indicate that the watch is setting up for time calibration
		reception.

		• If reception is successful, the second hand will move to
		Y (YES). 10 seconds later, the hands will move to the
	N (NO)	correct time.

Note

•To interrupt a receive operation and return to the Timekeeping Mode, press any button.

•If reception is not successful, the stopwatch second hand will move to N (NO).

5 second later, the stopwatch second hand will resume normal operation, without any adjustment of the hand setting.

•If the stopwatch second hand is pointing to Y (YES) or N (NO), you can return to the Timekeeping Mode by pressing any button.

Viewing the Latest Signal Reception Results

You can use the Receive Result Mode to check if signal reception was performed correctly.

To check the latest signal reception results1. In the Timekeeping Mode, press A.• If the watch was able to perform a successful signalreceive operation since midnight, the stopwatch secondhand will move to Y (YES). If the watch has been unableto receive any signal successfully, the second hand willmove to N (NO). • The watch will return to the Timekeeping Mode after fiveseconds or when you press A.

• The current receive result is cleared when the first auto receive operation is performed on the following day. This means Y (YES) indicates successful signal reception since the start of the current day.

•Y (YES) continues to be indicated even if an attempt at manual receive fails after auto receive is successful.

•If you adjust the time or date setting manually, the second hand will move to N (NO).

World Time

The World Time Mode shows you the current time in 27 cities (29 time zones) around the world.

• If the current time shown for a city is wrong, check your Home City settings and make the necessary changes.

• All of the operations in this section are performed in the World Time Mode.

Standard Time is indicated if the second hand moves to 6 o’clock, while Daylight Saving Time is indicated if it moves to 12 o’clock.

• The second hand will return to normal timekeeping after about two or three seconds.
