CONFIDENTIAL DISTRIBUTED UNDER LICENSE 7 Regulatory Agency Approvals Modular approval allows end users to place the OSDI module inside a finished product without the need for regulatory testing, provided no changes or modifications are made to the module circuitry. Changes or modifications could void the user’s authority to operate the equipment. The end user must comply with all of the instructions provided by the grantee, which indicate installation and/or operating conditions necessary for compliance.
CONFIDENTIAL DISTRIBUTED UNDER LICENSE 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.
CONFIDENTIAL DISTRIBUTED UNDER LICENSE 7.2.1 RF Human Exposure All transmitters regulated by Industry Canada must comply with RF exposure requirements. RSS-102, Radio Frequency (RF) Exposure Compliance of Radiocommunication Apparatus (All Frequency Bands), sets out the requirements and measurement techniques used to evaluate radio frequency (RF) exposure compliance of radiocommunication apparatus designed to be used within the vicinity of the human body.
