i must differ then pal, ive never delved into anything like playing films etc when i was engineering. The best i found was 1930's newspapers under the floor.
Did you power it back up with the flat battery connected. A completely drained battery will be damaged. If its now took charge have you powered it down and back up cleanly
I do agree, 3rd party certification of product should be mandatory for 3rd party certificated companies.
I wonder if our own insurance we carry would have a lower premium based on approval level and all products in use carrying a 3rd party approved cert?
agreed, all it prevents is resetting. Granted its not perfect but id say your work on rf integrity and ats etc is far more valuable. But I guess this is what interested you?
