Be sure the use of this product is allowed in the country and in the environment required. The use of 
this product may be dangerous and has to 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’s regulations and the specific environmental 
regulation. 

Do  not  disassemble  the  product;  any  evidence  of  tampering  will  compromise  the  warranty  validity.  
Follow 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 conform to the security and 
fire  prevention  regulations.  The  product  has  to  be  handled  with  care,  avoiding  any  contact  with  the 
pads because electrostatic discharges may damage the product itself.  
The system integrator is responsible for the functioning of the final product; therefore, care has to be 
taken  with  the  external  components  of  the  module  as  well  as  of  any  project  or  installation  issue 
because of the risk of disturbing the CDMA network or external devices or having impact on 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  this requirement cannot  be satisfied, 
the system integrator has to assess the final product against SAR regulations.
