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?
Well depends. If using modems then we use dial back and they call the office, either from a remote request or the customer pressing the relevant buttons. On the higher security stuff we use webways and the data is sent over an ssh tunnel.
