Hello all friends
I have kx-ns500 with one expansion cabinet kx-ns520,and all other cards that connected to it.
Suddenly kx-ns500 and kx-ns520 with red flashing and no tone .
I brought a new pbx kx-ns500 and disconnected the connecting card from the first pbx and connected it to the new one and connected the kx-ns520 together with it until I was sure whether it was still working or not..It is surprising that the new central starts working with the yellow flashing and then turns to red, and it pulses six times and stops for seconds and returns with a pulse six times and stops five times and returns to yellow flashing and pulses several times and returns to red. Until after disconnect EXP-M card the new pbx has same problem .
So please anyone can explain to me what happen..?
