3.1.3. RF Exposure 

All transmitters regulated by FCC must comply with RF exposure requirements. OET Bulletin 65 
“Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency 
Electromagnetic Fields” provides assistance in determining whether proposed or existing 
transmitting facilities, operations or devices comply with limits for human exposure to Radio 
Frequency (RF) fields adopted by the Federal Communications Commission (FCC). The bulletin 
offers guidelines and suggestions for evaluating compliance. 

If appropriate, compliance with exposure guidelines for mobile and unlicensed devices can be 
accomplished by the use of warning labels and by providing users with information concerning 
minimum separation distances from transmitting structures and proper installation of antennas. 

The following statement must be included as a CAUTION statement in manuals and OEM 
products to alert users of FCC RF Exposure compliance: 

To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a 
separation distance of 20 cm or more should be maintained between the antenna of this device 
and persons during operation. To ensure compliance, operation at closer than this distance is 
not recommended. The antenna(s) used for this transmitter must not be co-located or operating 
in conjunction with any other antenna or transmitter. 

If the A8520E24A91 module is used in a portable application (antenna is less than 20 cm from 
persons during operation), the integrator/OEM is responsible for performing Specific Absorption 
Rate (SAR) testing in accordance with FCC rules 2.1093. 

 

3.2. Canada 

(Industry Canada, IC) 

The A8520E24A91 modules has been certified for use in Canada under Industry Canada (IC) 
Radio Standards Specification (RSS) RSS-210 and RSS-Gen. 

Host devices which contain separately certified modules do not need to be recertified, provided 
that they meet the following conditions: 

a) The host device, as a stand-alone unit without any separately certified modules, complies 
with all applicable Radio Standards Specifications. 

b) The host device and all the separately certified modules it contains jointly meet the RF 
exposure compliance requirements of RSS-102, if applicable. 

c) The host device complies with the certification labeling requirements of each of the modules it 
contains. 

Note: Compliance of a module in its final configuration is the responsibility of the applicant. A 
host device will not be considered certified if the instructions regarding antenna configuration
