DORO NeoBio 10 Cordless Phone

I've gone through the registration process, no change. Help!!

The hand sets probably need to go through the 'registration' process with the base station. Look up the steps on how to do this in your manual.

One thing that the manual sometimes does not highlight clearly is that first you need to press and hold down a button on the main base station for a while until it beeps. Then you can go through the menu on the hand set to complete the registration process.
