Hi,
pelase excuse my english, but there is no good Panasonic board in german, so I hope you can help me anyway.

I tried to install a DLC8 card (KX3172NE) on my KX-TDA15. I used slot 5 as it is said in the manual. I then initialized the TDA15 on power on. When I try to add the card in the maintenance console the card ist described as "pre-installed" but I can not change the status to OUS or INS. When I do so, i get the message that the device is not found.

Is the card damaged or do I have forgotten something?

Thanks for your help.
