Safety Recommendations 

READ CAREFULLY 

Be sure that the use of this product is allowed in your country and in the environment 
required. The use of this product may be dangerous and must be avoided in the following 
areas: 

 

Where it can interfere with other electronic devices in environments such as 
hospitals, airports, aircrafts, etc. 

 

Where there is risk of explosion, such as gasoline stations, oil refineries, etc.  

It is the responsibility of the user to enforce the country regulations and the specific 
environment regulations. 

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 must be supplied with a stabilized voltage source and the wiring 
conform to the security and fire prevention regulations. 

The product must be handled with care, avoiding any contact with the pins because 
electrostatic discharges may damage the product itself. The same caution must be taken 
for the SIM, checking carefully the instructions 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, care 
must be taken of the external components of the module, as well as of any project or 
installation issue, because of the risk of disturbing the cellular network or external devices 
or having any impact on safety. Should there be any doubt, refer to the technical 
documentation and the regulations in force. 

Every module must be equipped with a proper antenna with the specified characteristics. 
The antenna must be installed with care to avoid any interference with other electronic 
devices and must be installed with the guarantee of a minimum 20 cm distance from a 
human body. If this requirement cannot be satisfied, the system integrator must assess 
the final product against the SAR regulation. 

The European Community provides some Directives for electronic equipment introduced 
on the market. All the relevant information is available on the European Community 
website: 

RE Directive (Directive 2014/53/EU) information.
