Sure, we’re here to help. Firstly, let’s try some basic troubleshooting steps. Check the power supply to ensure it’s functioning properly. Make sure all connections are secure and there are no loose wires. Next, examine the display for any error messages or unusual indicators. If there are any, note them down. Additionally, verify that all peripheral devices, such as detectors and pull stations, are properly connected and operational. If these steps don’t resolve the issue, it might be a more complex problem with the circuit board itself, in which case, it’s best to contact a certified technician for further assistance.
