etc
It is 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 a correct
wiring of the product. The product has to be supplied with a stabilized voltage source
and the wiring has to be conforming 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 of the functioning of the final product;
therefore, care has to be taken to the external components of the module, as well as
of any project or installation issue, because the risk of disturbing the GSM network or
external devices or having impact on the security. 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 with care in order to avoid any interference with
other electronic devices and has to guarantee a minimum distance from the body (20
cm). In case of this requirement cannot be satisfied, the system integrator has to
assess the final product against the SAR regulation EN 50360.
