RF Power (Read/Write Settings)
Use the RF Power menu to set the Read and Write power settings. The
Read and Write Power settings increase the strength of the RF Field
emitted by the printer’s antenna. The higher the value, the greater the
power of the RF Field.
If either the Read or Write Power settings are too high or too low, you
may not be able to read the tags or you may change the data that was
programmed in to adjacent RFID tags.
When using the read-only EM4122 protocol, the settings for Write Power
and Signal Adjust are ignored.
CAUTION: Use extreme caution when increasing or decreasing the
Read and Write Powers because the RFID tags may become
non-functional!
To change the settings, from the Main Menu, select Setup, then RFID.
Then follow these steps.
