Hello there;
I have Panasonic KX-TES824 hybrid system 3 outside lines and 8 extensions. The electrical power system went off in my village lately so did my panasonic system and when power was retrieved my telephone line did not. i reseted it by switching Off\On my panasonic system serveral times with no avail. I still could not find what the problem was. Not to menthioned my door Intercom was off but it worked fine after I switched Off\Off several view times.
Best of Regards
