What is the impact when the set Authenticate feature is set to true?

If you set authenticate to true, then only the keypads registered and within the keypad range are authorized to connect to the base. All keypads must be previously connected to the base station (when set “Authenticate” is set to false), to be able to connect again after set “Authenticate” is set to true.
