Setting the Attenuation
Reduces the strength of the RF Field emitted by the printer’s antenna.
The higher the value, the greater the reduction in the power of the RF
Field.
If the attenuation is set too low (too much power), you may affect the data
that was programmed into adjacent RFID tags. If the attenuation is set
too high (too little power), you may not be able to program the RFID tags
in the RF Field.
Caution: Use extreme caution when decreasing the attenuation
because the RFID tags may become non-functional!
