ABOUT RECEPTION OF RADIO SIGNAL

The BHM-612A is designed to automatically synchronize its
current time and date when within range of the U.S. Atomic
Clock.

When the unit is within range, its radio-control mechanism will
override all manual settings. The benefit of a RF controlled
clock is sustained accuracy without the need of manual adjustment.
