What to do if the AP&T AP-AB1208 high voltage alarm is on?

If the panel indicator red light is on, indicating a high voltage alarm in your AP&T Power Supply, it could be due to electromagnetic interference. Try turning off the power switch or unplugging the power cable and then restarting the ion bar. It could also be due to abnormal discharge, so confirm the installation location and ensure it is away from surrounding conductors. If these steps don't resolve the issue, the high voltage module may have no power supply or is damaged, requiring you to return it to the factory for maintenance.
