Displays 13:15 and Not Updating to Correct Time

Symptom
Clock displays 13:15 and is not updating to the correct time.
Cause
13:15 is a Primex code that represents the number of digits and clock's firmware version. The cause of this issue is due the clock is
not seeing a signal from a Transmitter.
Solution
1. Check the status of the Transmitter(s) to be sure they have the correct information on its display and red LED is not flashing.
Once the Transmitter is broadcasting, clocks will correct at their next scheduled update.
Digital Clock/Timer signal search frequency: every 10 minutes on the 5's (5, 15, 25, 35, 45, 55 minutes) of the hour, a clock's
receiver turns on to search for a Transmitter signal to receive a time update.
2. Does Transmitter have an External Antenna? During troubleshooting, you can power-cycle a Transmitter with an External
Antenna to allow it to broadcast continuously for 8 hours.
Broadcast (Transmit) Schedule Transmitter with Internal Antenna: broadcasts its synchronized time continuously to the
system clocks and devices.
Broadcast (Transmit) Schedule Transmitter with External Antenna: broadcasts its synchronized time to the system clocks
and devices from the 39th to the 6th minute of the next hour and changes to a standby mode during the 7th to the 38th
minute of the hour (standard broadcast schedule). During initial power-up, the Transmitter broadcasts for 8 consecutive
hours. After the 8 hour power-up period, the Transmitter reverts to its timed broadcast schedule.
3. Reset the clock. A reset causes the clock to scan for a broadcasting Transmitter frequency.
From its setting panel, press and release the Reset button - from the back side of the clock remove the small rectangular
access panel. Setting changes can be made while the clock/timer is ON and changes will take effect within a few seconds.
4. There is also a potential the clock is experiencing interference and not allowing the clock to receive 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.

When certain types of electronic light ballasts become defective they may radiate broadband noise, which can
