Catch-A-Call ID will ring in response to the change.
If Catch-A-Call ID rings in error when no one calls, decrease the sensitivity by picking up the phone and dialing # # # 3. Catch-A-Call ID will ring in response to the change.
The standard sensitivity (factory default) is restored by dialing # # # 2 on the phone attached to the Catch-A-Call ID phone port. Catch-A-Call ID will ring in response to the change.
