Not Subject to NDA
•
it can interfere with other electronic devices, particularly in environments such as
hospitals, airports, aircrafts, etc.
•
there is a risk of explosion such as gasoline stations, oil refineries, etc. It is the
responsibility of the user to enforce the country regulation and the specific
environment regulation.
Do not disassemble the product; any mark of tampering will compromise the warranty
validity. We recommend following the instructions of the hardware user guides for correct
wiring of the product. The product has to be supplied with a stabilized voltage source and
the wiring has to be conformed to the security and fire prevention regulations. The product
has to be handled with care, avoiding any contact with the pins because electrostatic
discharges may damage the product itself. Same cautions have to be taken for the SIM,
checking carefully the instruction for its use. Do not insert or remove the SIM when the
product is in power saving mode.
The system integrator is responsible for the functioning of the final product. Therefore, the
external components of the module, as well as any project or installation issue, have to be
handled with care. Any interference may cause the risk of disturbing the GSM network or
external devices or having an impact on the security system. Should there be any doubt,
please refer to the technical documentation and the regulations in force. Every module has
to be equipped with a proper antenna with specific characteristics. The antenna has to be
installed carefully in order to avoid any interference with other electronic devices and has
to guarantee a minimum distance from the body (20 cm). In case this requirement cannot
be satisfied, the system integrator has to assess the final product against the SAR
regulation.
The equipment is intended to be installed in a restricted area location.
The equipment must be supplied by an external specific limited power source in
compliance with the standard EN 62368-1:2014.
The European Community provides some Directives for the electronic equipment
introduced on the market. All of the relevant information is available on the European
