RFID Antenna Power in Hands-Free Mode

Parameter # F1h C8h

This parameter controls the antenna RF power when operated in hands-free mode. Table 3-6 lists the levels and

the associated range as a percent of the baseline range. The baseline range is the range that results when the

power level is set to the maximum level of 7, and can vary depending on the environment, tag sensitivity, and

orientation.
