RESET FOCUS

You can use a RESET FOCUS command to clear the target level information in the Reader/Writer for
all monitored RF Tags during operation in Focus Mode.
After the Reader/Writer completes reception of the RESET FOCUS command, it returns a response,
clears the information, and then starts monitoring for RF Tags again.
