Notes 
The four operating modes are as follows: 
•  Controller Only — Buzzer sounds only when a token is shown to the controller 
reader. 
•  Reader Only — Buzzer sounds only when access is granted / denied. 
•  Silent Mode On — Buzzer is silent. 
•  Silent Mode Off — Buzzer sounds when access is granted / denied and when a 
token is shown to the controller reader. 
Resetting the controller defaults it to Controller Only mode.
