Hi
I have Panasonic TDA600 Pabx And I installed kx-dt543 on it but it does not work probably
I got our TDA600 on v 5 (Which doesn't meets the requirement)
Yet the DT5xx Series PT not really working properly.. it still showing 0000 in the display, buttons are not working, no ring tone when called..BUT able to call!

Any possible reasons?
and it has a dlc 0172 card whitch has v7 only
thanks

The TDA600 (at least here in US) does not support the DT5xx phones, we just upgraded a TDA600 to TDE600 this being one of the reasons.

i have the same situation
just upgrade the card firmware to version 8 and it will work just fine
