Using the Reader

Present the proximity card face-on to the reader until you hear a "bleep". The maximum read range
is typically 4" ( 10cm). If the green indicator is lit, the card has been accepted and the door is
unlocked. If the red indicator is lit, either the card has not been accepted, or you do not have
access through the door.
