Add and register a doorbell
You can add another new doorbell ( IS741, purchased separately) to your IS7121
telephone system. This telephone system accommodates up to two doorbells.
Each new doorbell must be paired to the telephone base before use.
Make sure the doorbell is powered on before pairing it to the telephone base.
Press and hold /FIND HANDSET on the telephone base for about four seconds
until the IN USE light turns on.
Press and hold /DOORBELL on the doorbell about 10 seconds until the
doorbell light flashes slowly. The doorbell light turns on steadily and you hear a
confirmation tone from the doorbell when the registration is successful. It takes
about 60 seconds to complete the registration process.
For details on installing the doorbell, refer to the Installation guide that comes with
your package.
