I just bought a Mark II, having had a Mark I working fine for several years. I managed to register the Mark II with my pyramid base, but when I try to use it to dial out or pickup an incoming call, the display shows "Line is Busy" and I hear a series of beeps in the earpiece.
I've checked the wiring to the base - it works fine with the old Mark I - I can send and receive calls OK using the Mark I on the same base.
I spoke to the dealer and they say the message means my phone line is at fault, but that doesn't explain why the Mark I works fine.
Can anyone help shed light on this?
Thanks
