INSTALLATION AND EXTERNAL CONNECTION
PRECAUTIONS ON INSTALLATION
IF INSTALLING ON A METAL WALL
If you install the reader on a metal wall, the read range may be reduced.
To avoid this problem, it is recommended to insert the spacer between the metal wall and the reader as shown
below.
IF INSTALLING MORE THAN ONE READER SIDE BY SIDE OR
FRONT AND BACK
If you install more than one reader side by side or front and back, the read range may be reduced. In this case, if
you present a card to one reader, the other reader may recognize the same card, meaning both readers read the
same card simultaneously.
To avoid this problem
, keep at least 20 cm of space between the two readers.
