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.
When faulted, the reader can not accept a card read. Check wiring for faults or replace reader.
The reader is now working correctly.
