Model: Levo and Classic Digital Clocks & Timers
All or some of the symptoms may be present.
The colon between the clock hour and minute is flashing.
The clock's time may not be accurate.
Identify scope of clocks experiencing issue - single clock or all clocks/clocks in specific area.
Reset the clock to initiate a manual signal search. Press and release the button located in its setting panel.
Setting panel Levo Series (current model): From its backside, remove the small rectangular access panel.
Setting panel Classic Series (discontinued): From its front side, remove the small rectangular access panel located in the upper center. A small screw driver can be used to gently pry the center top edge of the panel forward.
All clocks in a specific area:
Is the Transmitter red LED flashing and/or is the information displayed on the front LCD not correct? If yes, the Transmitter is in an error state that may result in the clocks not receiving a time signal. Resolve the Transmitter error state. Once the Transmitter is in a normal state, the clocks will receive and synchronize their time at their next scheduled signal search.
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.
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.
When certain types of electronic light ballasts become defective they may radiate broadband noise, which can interfere with wireless devices. While interference issues are unlikely with the Primex system, high levels of noise present in the 72-76MHz range could potentially cause clocks which are located far from the Transmitter and also within the close proximity of these ballasts to not receive a signal. Very limited instances have occurred in the past, which has only been found to happen when ballasts become defective.
Determine if Transmitter broadcast schedule or clock signal search frequency is cause of clock not updating its time.
Single clock: reset clock to search for signal.
All clocks/clocks in specific area: check Transmitter status and resolve any issues.
Verify signal coverage at install location or area.
Verify no interference at install location or area - defective ballast.
If the issue cannot be resolved, additional troubleshooting is required.
