I have a Magix 4424LD+ Telephone Set. I have it hooked up to a 412 TDL LS-ID Card, the phone works fine just cant get the display to come up. This is happening on all the sets. Any info would be helpful.
Thanks for that reply.. Does the 4400D also require a power supply to run the display. It's an analog phone right, so why would this require a power supply. Thanks again.
