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.
