[techbrain1]

Hello,
Please am trying to connect panasonic digital phone kx-dt543 to panasonic tda 100 pbx.But it is not working, it shows zeros on the screen.
Please I need someone to help me make this work.I guess is because the file system is not compactible with the phone.
Please help me out.

Firmware on the TDA is not compatible with the 500 series phones

You can upgrade the system firmware to v5.010 and upgrade the vard to v8 to work with v5xx phones

Hello obtsystems,
Per the challenge I was facing,I finally got a bin file with the name pdhlc v080.
I put the digital card in the Panasonic TDA 100 out of service.Went to utility and tried sending the file from my PC to the SD card but got an error file.
Anyway, I will be happy if u can as well outline the procedure to make the Panasonic kx-dt543 work with the Panasonic TDA 100.
Attached is snap shot of the error I got.
