Step 1: Before you begin registration, make sure the headset is out of the charger.
Step 2: Press and hold FIND HS button on the telephone base for about four seconds and it shows Registering... Please wait. Release /FIND HS.
Step 3: Place the headset back to the charger. The telephone base will beep as an indication that the registration is successful.

A:AnswerDon't know about that - - I have a vtech system and wanted this to replace the (wearing out) headset I already have. Was unable to get the new one to
"register" (apparently need to "unregister" the old one first? But no info anywhere on how to do so...) so I just returned it, unused. I guess I'm going to get a whole new one-phone/one-headset system as I am very, very happy with the headset.
