increasing the NN value until the read zone matches the desired read zone.
When the desired read zone is established, test the read zone with simulated and real
traffic by performing the following procedures.
To test the read zone
1. Ensure that the MPRX is in data mode.
2. With the MPRX operating, place one tag behind your back while you hold another
tag in the new read zone. If a valid read, the data from the tag held in the read zone
displays on the host device screen.
3. Switch tags, placing the other tag behind your back and holding the first tag in the read
zone. If a valid read, the data from this tag held in the read zone displays on the host
device screen.
4. If both tags are read, you have successfully adjusted the read range. If one or both tags
did not read, follow the suggestions in “Verifying Tag Read Capability” on page 8–8 .
