FCC STATEMENT : 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, and (2) This device must accept any interference received, including interference that may cause undesired operation. Warning: Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: tenna. receiver is connected. FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body.
FCC INFORMATION (additional)OEM INTEGRATION INSTRUCTIONS:This device is intended only for OEM integrators under the following conditions: Themodule must be installed in the host equipment such that 20 cm is maintained betweenthe antenna and users, and the transmitter module may not be co-located with any othertransmitter or antenna. The module shall be only used with the internal antenna(s) thathas been originally tested and certified with this module. As long as 3 conditions aboveare met, further transmitter test will not be required. However, the OEM integrator is stillresponsible for testing their end-product for any additional compliance requirementsrequired with this module installed (for example, digital device emissions, PC peripheralrequirements, etc.).Validity of using the module certification:In the event that these conditions cannot be met (for example certain laptop configurationsor co-location with another transmitter), then the FCC authorization for this module incombination with the host equipment is no longer considered valid and the FCC ID of themodule cannot be used on the final product. In these circumstances, the OEM integratorwill be responsible for re-evaluating the end product (including the transmitter) andobtaining a separate FCC authorization.End product labeling:This transmitter module is authorized only for use in device where the antenna may beinstalled such that 20 cm may be maintained between the antenna and users. The finalend product must be labeled in a visible area with the following: “Contains FCC ID:2AJDA-USRGM3”.Information that must be placed in the end user manual:The OEM integrator has to be aware not to provide information to the end user regardinghow to install or remove this RF module in the user's manual of the end product whichintegrates this module. The end user manual shall include all required regulatoryinformation/warning as show in this manual.This device must be kept away from all persons by 20cm or more and installations usingless distance, or installations using antennas with gain greater than that with which thiswas Certified will require additional approvals.
