 Stable Operation
When the Reader/Writer communicates with an RF Tag, it diagnoses the communications leeway and
reports the result. You can check the communications leeway to appropriately install the Reader/Writer
and RF Tags to achieve stable operation of your OMRON RFID System.
For details, refer to Using Communication Diagnostic and the RF Analyzer in Section 6 Functions .
p.118
If you use the RFID System under installation conditions that provide a high communications leeway,
you can reduce communications troubles during system operation and achieve stable line operation.
