User's Manual

Present the card face-on to the reader until you hear a "bleep". Cards can be presented in rapid succession; there is no need, for
example, to wait for "GREEN LED’s" to disappear before presenting another.
If the reader has been enabled for user-code mode at the controller, you can gain access by pressing the O key, entering your
card number, then pressing the P key.
