4.2.1 Safety warnings review the structure
Equipment for building-in. The requirements for fire enclosure must be evaluated in the end product
The clearance and creepage current distances required by the end product must be withheld when the
module is installed
The cooling of the end product shall not negatively be influenced by the installation of the module
Excessive sound pressure from earphones and headphones can cause hearing loss
No natural rubbers, no hygroscopic materials nor materials containing asbestos are employed
4.2.2 Declaration of conformity – United States only
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions:
this device may not cause harmful interference
this device must accept any interference received, including interference that may cause undesired operation
Radiofrequency radiation exposure Information: this equipment complies with FCC radiation
exposure limits prescribed for an uncontrolled environment for fixed and mobile use conditions.
This equipment should be installed and operated with a minimum distance of 20 cm between
the radiator and the body of the user or nearby persons. This transmitter must not be
co-located or operating in conjunction with any other antenna or transmitter except as
authorized in the certification of the product.

transmission line, connector, cable losses and radiating element gain) must not exceed 8.39 dBi
(850 MHz) and 3.11 dBi (1900 MHz) for mobile and fixed or mobile operating configurations.
The gain of the system antenna(s) used for SARA-U260 / SARA-U280 modules (i.e. the combined
transmission line, connector, cable losses and radiating element gain) must not exceed TBD dBi
(850 MHz) and TBD dBi (1900 MHz) for mobile and fixed or mobile operating configurations.
