Operation: The module is controlled by the Master Clock and will not operate on its own. When connected to a Master Clock as a main transmitter, it will transmit the time for 570 ms, as specified, once a minute. If used as a Repeater, it will receive time from a main transmitter or clock and re-transmit the time thereby increasing the coverage area, thus keeping all the slave clocks synchronized to the Master Clock. FCC Statement: This device complies with part 15 of the FCC Rules.
