Warning: 

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 

(1)

 

this device may not cause harmful interference, 

 

and 

 

(2)

 

this device must accept any interference received, including interference that may cause undesired operation.

 

 
 

The S4W contains a 2G/3G module certified under FCC ID: N7NHL8548. 
This equipment complies with the FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment 
should be installed and operated with a minimum distance of 20cm between the radiator and any part of your body.

 

 
This device was tested and found to comply with the limits of Class A digital devices, pursuant to Part 15 of the FCC Rules. 
These limits are designed to provide reasonable protection against harmful interference when the device is used in a 
commercial environment. This device generates, uses and can emit radiofrequency energy and, if not installed and used 
following the instruction manual, can cause harmful interference to radio communications. Operating this device in a 
residential zone is likely to cause harmful interference, in which case the user will be held responsible for correcting the 
interference at his/her own expense. 
 
Any modification made to this device that has not been explicitly approved by LACROIX Sofrel may cause harmful interference 
and voids the FCC authorisation to use this device.
