INTENDED USE

The RFID modules of the TWN4 MultiTech Nano family allow users to read and write RFID media in
the 125 kHz (LF) and 13.56 MHz (HF) frequency bands for identification purposes. In addition, some
devices also support the BLE (2.4 GHz) technology. The modules are intended to be integrated into a
host device. All devices must be used in environmental conditions according to the respective
product data sheets and installation instructions related to the products.
Any use other than the intended use described in this section, as well as any failure to comply with
the safety information given in this document, is considered improper use. ELATEC excludes any
liability in case of improper use or faulty product installation.
