5 Application program rules
Due to national restrictions not all parameter values are valid in each version of the i-CARD CF-350.
Programmers of application software are strongly recommended to read the documentation which
comes with the development package.
Note
When trying to set an operation mode or output power which is not allowed in the national version
the i-CARD CF returns with an error code. Please refer to the library manual.
According to ERC/REC70-03 a maximum duty cycle of 1 % (i-Q350 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.
