A:Answer Alicia - The Vtech CS6909 is an accessory handset designed to work with a CS6919, CS6929 and CS6949. Here's the procedure on how to register:
1. Place the new handset on the telephone base.
2. After about 10 seconds, the handset displays "Registering...". When the registration process completes, the handset displays "Registered" and you will hear a beep. The registration process can take up to 90 seconds to complete.
Hope this helps!
