I believe the factory reset will work if the procedure is followed correctly.

A continuous rated plug in power supply with d/c output might indeed be the answer. Soldered or a mini jack type plug - as an E/Eng you most likely could do that - but would it work?

If it helps :- Always use alkaline batteries Never use rechargeable batteries Left column both batteries + pointing down Right column both batteries + pointing up "Batteries low" sign means 1 month battery power left (Dry solder joints) - re soldering the batteries spring connection terminals...
