Caller Id set allows you to specify if a telephone displays the Call Display information when a call is ringing on an external line(After the call is answered,Call Display information is allways shown at the telephone that answered the call).The Caller ID set for target lines is the same set that has apperance on that target line.Press CHANGE to select the setting.

Of course the telephone must be a ringing set,also while the set is ringing try the feature code for Caller ID to see if you are getting the translation from the carrier.

Good luck
