Frequently Asked Questions
How do I know if the clock is receiving data?
Perform Diagnostic 2. See the section labeled “Diagnostic Test #2 - Comprehensive Test”. The result should
correspond to your system’s synchronization settings.
Example 1: The two-wire digital system should result in the clock recieving communication within the
last hour.
Example 2: Once-a-day sync systems may return a result of 11 hours or more, depending on when you
conduct the test. In this case, the test should be conducted less than nine hours after the synchronization
signal is sent.
What size utility/gang box is needed?
A standard single gang box is required for wall mounting a clock. However, if you are installing a double
mount or flag-mount clock, then a standard double gang box is required.
Do I need to power up all the clocks at the same time?
No. Clocks that are added to the system after power up will begin running and wait for correction signals
from the master clock. Sync-wire systems may take up to 24 hours to receive a correction signal.
Do I have to reset the clock if it suffers a power outage?
No. The clock will resume operation after the power outage, and will adjust to the correct time as soon as
it receives a signal from the master clock.
What happens if I power the Valcom Wired Clock before connecting the master clock?
The clock will begin to run, but the time displayed will be incorrect. As soon as signal wires from the
master clock are connected and a synchronization signal is sent, the Valcom Wired Clock will correct itself
to display the correct time.
Can I manually set the time on the clock?
No. Furthermore, attempting to open the front crystal or moving the hands manually will damage the clock
and void your warranty.
