So just just picked up 2 from a mcdonalds service call ..replace battery 12v 4ah battery ..connect to ac...hold down power and mute button till systems beeps ...continue to hold to so see all icons on the screen then release. ...it worked for me
I dont think so... if there is no button in the middle of the back, then your S.O.L. their may be a hard wired fuse on the PCB...
Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/lisa_52daba487e5b4d53

Is there a factory reset button, switch or something that can reset a breaker in the unit? 16 hours before the two units failed, both were showing fully charged with no low battery indicator.
