Reader Power Up

When the power supply is connected, the reader starts an internal

initialization sequence. This sequence momentarily lights the

LEDs as follows:

1. Transmit on

2. Sense on

3. Power on

4. Fault on

5. All four on

6. Beeper on

If the Fault LED flashes on at the beginning of the sequence, the

reader has detected a software load fault. Restart the reader to

clear the fault.
