Good evening everyone.
Merry Christmas to us all.
Please, am having a little challenge.
Panasonic Kx-Tem824 when powered on, almost all the lines has busy tones and can't make calls while others have no tone at all.
What do I do?
Make System data clear so everything should work OK, but when you turn off the power all the lines will be busy.
Disconect PBX from main power and check the lithium battery on the main board, if it is 0 V then a new one should be replaced.
There are no stupid questions, there are only stupid answers!
