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" (page E-20).
• 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" (page E-25).
