NOTICE
Close unused connectors
Note that the readers only have the specified degree of protection when all connectors are
in use or when unused connectors are closed with the protective caps.
CAUTION
Emitted radiation
The transmitter complies with the requirements of Health Canada and the FCC limit values
for subjecting persons to HF radiation, provided that a minimum spacing of 26 cm exists
between antenna and person. When the antennas are installed, you must therefore ensure
that a minimum spacing of 26 cm is maintained between personnel and antennas.
Mounting/installing the device
You can mount the reader in the following ways:
●
directly on a flat surface using the VESA 100 mounting system (torque
≃
1.5 Nm).
The positions of the mounting holes for the device are shown in the section Dimension
