Model: Personal Series Clock
Initiated validating its signal by pressing the button on the back of the clock and clock it not emitting the expected beeps.
Pushing and IMMEDIATELY releasing the button located on the back of the clock initiates the clock to validate its signal. The clock scans all channels looking for a Transmitter signal. Once the clock finds a channel with a Transmitter signal, it emits a series of beeps. The clock beeps each time a valid time signal is received, which should be once per second. The beeping continues for one minute.
This may be due to the clock is not receiving a signal from a Transmitter or the batteries are defective.
Is the Transmitter a 1 Watt with an External Antenna or a 5 Watt or 30 Watt Transmitter? If yes, was the clock installed between the 7th and 38th minute of the hour? It should set at the 39th minute of the hour. You can also power the down the Transmitter, wait 30 seconds, and power back on. A power on, power down forces the Transmitter to broadcast for eight consecutive hours.
A Transmitter with an Internal Antenna continuously broadcasts is signal.
Replace the 4 Cell batteries using fresh superior-quality alkaline with an expiration date with an expiration date at least 5 years past the installation Date. Another option is to replace with batteries from a clock that is operating correctly, which would validate if cause is not the batteries.
Verify the Transmitter(s) is not in an error state. The time not being correct on multiple clocks is normally due to a Transmitter has lost it time source connection (GPS or NTP). After the error state is resolved, the Transmitter should be powered down and powered back on to allow it to resynchronize with its time source. Refer to the Transmitter model Troubleshooting topics.
If the Transmitter is not in an error state, there is also a potential the clock is experiencing interference and not allowing the clock from receiving a broadcasting signal. Move the clock to an area where other clocks are set to the correct time. This task should isolate the issue to either a defective clock or signal issue.
