Optima XM panel - tamper deactivation?
I'm annoyed as I've done this before and can't remember what I did! I want to open up my Optima XM panel to check how wires are routed behind it, before carrying out some drilling work nearby.
Is it just a case of entering the security code, before unfastening the screw on the right hand side of the panel, or are there panel buttons to press also?
thanks in advance!
