vanced Settings
You can specify the transmission power for read communications and write communications. If you
adjust the transmission power according to the communications distance, you can suppress radio
wave interference and reduce reading non-target RF Tags.
*1. The communications distance is shorter when writing data to an RF Tag in comparison with reading data from
an RF Tag. The difference in the communications distance varies depending on the RF Tag.
You can use the channel setting to select the channel (i.e., the frequency band) to use for execution
of communications commands.
Use this setting to prevent mutual interference with nearby Reader/Writers and interference with
other wireless devices.
