Critical

What to do

Why this happens

Possible causes include an under-voltage or over-voltage condition at the power supply, use of a plug receptacle leading to voltage drop, connecting wire length causing a momentary drop (e.g., 1m can reduce up to 10V), or a fault in the main PBA.

How to fix it

Make sure the power cord is firmly plugged in and the breaker is on. If the error persists, you may have a wiring issue — have an electrician check the outlet.
