Re: My Smart-1 4 line looses programming
I looked at mine and can't find a battery or a supercap. Perhaps it is corrupt NVM that causes the processor to do a hard reset?
The only other thing is a "long star @ power-up" reset being performed, however unlikely.
Even when these were new, it could be a challenge to find a phone that sent continuous DTMF.
