Precautions for Correct Use
• The RUN indicator will light cyan during adjustment.
• For the adjustment, place the RF Tag at the farthest distance from the Reader/Writer that
would be normal in the actual application.
• Do not move the RF Tag during adjustment. Doing so will prevent determining the optimum
power.
• When you use this function, use the same RF Tag that you will use in actual operation. If you
change the type of RF Tag, the adjustment results will differ.
• When the write transmission power is automatically adjusted, data is actually written to the
RF Tag.
• Any RF Tag communications errors that are detected as a result of communications with RF
Tags during adjustments are recorded in the command error log.
• If you close the Web browser interface or disconnect the communications cable during the
adjustment, the test operation status (i.e., the RUN indicator lit in cyan) may continue. If that
occurs, cycle the power supply to the Reader/Writer to reset it.
