Change the control timing so that communications start when there is an RF Tag in
the communications field of the Reader/Writer.
Measure the noise and implement noise countermeasures.
Check the influence of surrounding metal and make sure there is sufficient
communications range.
RF Tag communications
error
2002 hex
Change the control timing so that communications start when there is an RF Tag in
the communications field of the Reader/Writer.

communications range.
UID mismatch error
2003 hex
Perform communications when the RF Tag for which data is to be restored is in the
communications field of the Reader/Writer.
