According to ERC/REC70-03 a maximum duty cycle of 1% (i-Q- tags) is allowed in Europe. Due to the
protocol used on the RF link this means no restrictions for interactive operation. However in continuously
running applications the application programmer must ensure observance of these rules. For details please
see the documentation which comes with the development package.
To minimize spurious radiation consecutive scans must be separated by pauses with a length of at least
0.2 seconds. Again this is no restriction for interactive application as a scan is typically followed by manual
selection of a tag in a list which normally lasts longer than this required time.
