Radio-controlled Atomic Timekeeping
|
| Your watch receives a time calibration signal and updates | |
|
| its time setting accordingly. | |
|
| time | • This watch is designed to receive the time calibration |
|
| calibration | signal transmitted from Shangqiu City, Henan Province, |
|
| signal | |
|
| China (Call Sign: BPC, Frequency: 68.5 kHz). | |
|
|
| • Your watch will be able to receive the signal whenever |
|
|
| |
|
|
| |
|
|
| Beijing (UTC+8) is selected as its Home Time Zone, and |
|
|
| the watch is within range of the transmitter. The initial |
|
|
| factory Home Time Zone setting of the watch is Beijing |
|
|
| (UTC+8), so you will not need to change the setting if |
Transmitter | you are in the same time zone (UTC+8) as Beijing. | ||
|
|
| • As of January 2008, China does not use Daylight Saving |
|
|
| Time (DST). If China does go to the Daylight Saving |
|
| Watch | Time system in the future, some functions of this watch |
|
|
| may no longer operate correctly. |
•See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.
Chinese Time Calibration Signal
The Chinese time calibration signal (BPC) is maintained by the National Time Service Center (http://www.ntsc.ac.cn/) of the Chinese Academy of Sciences, and is transmitted from a transmitter (68.5 kHz) located in Shangqiu. The time data of the Chinese time calibration signal is maintained by the National Time Service Center.
•Note that transmission of the calibration signal may be interrupted occasionally due to maintenance, lightning, etc.
Current Time Setting
This watch adjusts its time setting automatically in accordance with a time calibration signal. You also can perform a manual procedure to set the time and date, when necessary.
•Whenever you need to travel outside of the time zone where Beijing is located (UTC+8), use the procedure under “To select your Home Time Zone” to change the watch’s Home Time Zone setting as required.
•When using the watch outside the range of the time calibration signal transmitter, you have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.
•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.
•The actual level at which some functions are disabled depends on the watch model.
•Be sure to read “Power Supply” for important information you need to know when exposing the watch to bright light.
If the analog hands aren’t moving...
If the analog hands aren’t moving, it means that the power saving mode has stopped them to save battery power.
•See “Power Saving” for more information.
•The hands also stop when the watch’s battery runs down.

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 five 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.
