Noise Monitor View
You can check the graphed noise level (one second intervals) around the Reader/Writer.
Select from the screen, the type of the RF tag you want to use, because the communication
performance will be changed by the combination of the type of the RF tag to be used.
The "Normal area", "Precaution area" and "Warning area" will be appeared on the screen according to
the type of the RF tag to be used.
Normal area Means the noise level that communications range can be reduced to about less than 20%
Precaution area Means the noise level that communications range can be reduced to about 20% to 50%.
Warning area Means the noise level that communications range can be reduced to about 50% or more.
When the Reader/Writer is running in safe mode, this screen can not be operated. Run the Reader/Writer in RUN
mode.
About the relationship between the Reader/Writer communication performance and the noise level, refer to Noise Measurement
in Section 6 Functions.
