FCC MODULAR APPROVAL INFORMATION EXAMPLES for Manual 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. (2) This device must accept any interference received, including interference that may cause undesired operation. -
Page 16: Upgrade Firmware
Validity of using the module certification: In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization for this module in combination with the host equipment is no longer considered valid and the FCC ID of the module cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. - Page 17 FCC MODULAR APPROVAL INFORMATION EXAMPLES for Manual 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. (2) This device must accept any interference received, including interference that may cause undesired operation. CAUTION: Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
- Page 18 End product labelling The label for end product must include “Contains FCC ID: A3LWCB731M, Contains IC: 649E-WCB731M”. “ CAUTION: Exposure to Radio Frequency Radiation. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance of 20cm between the radiator and your body.
- Page 19 Requirement per KDB996369 D03 2.2 List of applicable FCC rules List the FCC rules that are applicable to the modular transmitter. These are the rules that specifically establish the bands of operation, the power, spurious emissions, and operating fundamental frequencies. DO NOT list compliance to unintentional- radiator rules (Part 15 Subpart B) since that is not a condition of a module grant that is extended to a host manufacturer.
