Colon between the hour and minute is flashing

Symptoms
All or some of the symptoms may be present.
The colon between the clock hour and minute is flashing.
l
The clock's time may not be accurate.
l
Problem
The clock has not received a signal from a Transmitter for more than 3 days.
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.
Analyze
1. Identify scope of clocks experiencing issue - single clock or all clocks/clocks in specific area.
Single clock
a. Reset the clock to initiate a manual signal search: press and immediately release the button located in its setting panel.
Levo Series - 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.
All clocks/clocks in specific area: verify the Transmitter(s) is not in an error state. If multiple Transmitters on site, start
with the Master Transmitter and then proceed by verifying the other units.
i. Is the Transmitter's red LED flashing and/or is information displayed on its front display not correct? If yes, the
Transmitter is an error state that may result in the clocks not receiving a broadcasting signal. Resolve the issue by
completing the troubleshooting topics for the Transmitter model. Once the Transmitter is in a normal state and
broadcasting, clocks correct at their next scheduled update.
2. If a clock(s) continue not to set its time, it may be due to the signal coverage at the install location or area.
Perform a signal check. Take the clock with the issue to a known good signal area with clocks that are set to the correct time
with a solid colon. Apply power to the clock experiencing the issue. Press and release the clock's reset button in its setting
panel. A reset causes the clock to scan for a broadcasting Transmitter frequency. If the clock sets to the correct time, it's a
signal issue at its original installation location.
3. If a clock(s) in a specific area continues not set its time, it may be due to interference preventing a clock from receiving a
broadcasting signal.
