You can verify that a clock is receiving a signal at its install location. This is completed by initiating a manual signal search locally at the clock, which resets the clock.
Before you begin, verify the main Transmitter is transmitting (broadcasting) and is not in an error state. This allows the clock to receive a signal, either directly from the main or a repeater Transmitter.
From the back of the clock, press and release the red button. You can also remove and reinsert its batteries.
The clock emits a double-beep and the clock begins to search for a signal from the Transmitter. The clock emits subsequent beeps to indicate its signal strength as described below. Also, when a signal is received the clock will reset its time.
