What is the different between the "beep keypad" and the "beep keypad ranged" features?

1. Setting beep keypad to true will make all connected keypads beep continuously. You can use this function to make sure that all keypads are connected to the right base 2．If you set Beep Keypads Ranged to true, and then all keypads that are connected to the base, but have moved out of the RF range, will beep continuously. This function is useful for checking if all keypads are within range and are able to send and receive information from the base.
