6-5. Installation Considerations
1. When installing a reader on a metal wall
The read range may get reduced if the reader is installed on a metal surface. To prevent such
a read range reduction, install a Spacer between the metal surface and the reader.
2. When installing more than two readers side-by-side or back-to-back
The read range may get reduced if more than two readers are installed side by side or back
to back. Also, when a card is presented to one of the readers, the other reader may wrongly
recognize the card as well. To prevent such interference, make sure the distance between
readers is at least 20cm.
