Safety Recommendations

 

Make sure the use of this product is allowed in your country and in the environment 
required. The use of this product may be dangerous and has to be avoided in areas where:   

 

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 
Community website:
