A:Answer Hi - The VTech CS6949 supports a maximum of five devices. The cordless handset compatible with the telephone base is the model VTech CS6909. Here's how you can register a cordless handset to the telephone base.
Step 1. On the telephone base, press and hold FIND HANDSET for about 4 seconds until the IN USE light turns on, display shows Registering......
Step 2. On the cordless handset, press QUIET#. Display shows Registered and you will hear a confirmation tone.
Thank you,
-VTech Support
