Confidential
⚠ IMPORTANT: les fabricants d'applications portables contenant les modules de la SARA-R5 series
doivent faire certifier leur produit final et déposer directement leur candidature pour une
certification FCC ainsi que pour un certificat ISDE Canada délivré par l'organisme chargé de ce type
d'appareil portable. Ceci est obligatoire afin d'être en accord avec les exigences SAR pour les
appareils portables.
Tout changement ou modification non expressément approuvé par la partie responsable de la
certification peut annuler le droit d'utiliser l'équipement.
4.4 European Conformance
The SARA-R5 series modules have been evaluated against the essential requirements of the Radio
Equipment Directive 2014/53/EU (RED). In order to satisfy the essential requirements of the RED, the
modules are compliant with the following standards:
Radio Spectrum Efficiency (Article 3.2):
o EN 301 908-1
o EN 301 908-13
Electromagnetic Compatibility (Article 3.1b):
o EN 301 489-1
o EN 301 489-52
Health and Safety (Article 3.1a)
o EN 62368-1
o EN 62311
⚠ Radiofrequency radiation exposure Information: this equipment complies with 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.
⚠ The gain of the system antenna(s) used for SARA-R5 series modules (i.e. combined transmission
line, connector, cable losses and radiating element gain) must not exceed the values stated in the
Declaration of Conformity of the modules, for mobile and fixed or mobile operating configurations
The conformity assessment procedure for the SARA-R5 series modules, referred to in Article 17 and
detailed in Annex II of Directive 2014/53/EU, has been followed.
Thus, the following marking is included in the product:
