Anytime, in case the reader goes abnormally, user can use another way to let reader go into boot mode and 

re-download firmware. Power off reader, set the switch S1-2 on, and then power on the reader to force reader gets 

into boot mode. As soon as f/w download done, user have to power off the reader and turn switch S1-2 off.   

The reader cannot do normal operation while switch S1-2 is on.
