3.0 Operation
When power is first applied to the reader, it performs internal power up diagnostics. If it is functioning
properly, the reader will flash the LED and beep twice. After the power up diagnostics are completed and
the reader is in a READY status mode you may present a standard or option card to the reader.
3.1 Startup Diagnostic
The readers have an internal diagnostic routine to assure reader operation at start-up, as well as a means to
test the integrity of the data lines. When power is first applied to a reader, it will beep and flash twice to
let the installer know that it has performed an internal check and is functioning properly. If the reader
start-up routine determines one of the critical memory devices inside the reader has failed, the reader will
alternately flash the LED red and green.
