It communicates with the MIC-WRL-CHG-410 "Base" component. These two components operate as a pair and comprise the operational wireless microphone system. FCC ID: YJV-TRN420 The device contains the following radios: ISM Radio: 902-928 MHz Location of transmit antenna(s): Report No. WTVD0035.46/43 PRODUCT DESCRIPTION 2014-12-10 Testing Locations: For clarity, the sides of the EUT are referred to as front side, back side, LCD screen side, Mic port side, mode button side, and power button side. Per the manufacturer, the EUT can have two different clip accessories. Both of these clip accessories contain metal springs. The manufacturer specifies that the EUT should be used with a clip accessory, however the EUT is capable of transmitting without a clip accessory. Per the manufacturer, the EUT can also optionally use a microphone accessory. When no clip accessory is used, the EUT can have any orientation exposed to the human body. These orientations are tested with and without the microphone. Per the manufacturer, when a clip accessory is used, the EUT would be clipped to the human body and only the back of the EUT would be exposed to the human body. The back of the EUT was tested with both clip accessories both with and without a microphone accessory. There was no additional spacing added between the EUT and the phantom. Testing Objective: To demonstrate compliance of the 902-928 MHz ISM radio with the SAR requirements of FCC 2.1093:2020. Scaling: Max power Per FCC KDB 447498, the measured SAR values were scaled to the maximum tune-up tolerance limit. The results are referred to as the “Reported SAR” values. The following formula was used to calculate the linear SAR scaling factor: SAR scaling factor = ((Tune-up Tolerance Power (mW)) / (Measured Power (mW)) A summary of scaling factors is as follows: Band Tune-up Tolerance Powe…

The results of this test pertain only to the sample(s) tested. The specific description is noted in each of the individual sections of the test report supporting this certificate of test. This report reflects only those tests from the referenced standards shown in the certificate of test. It does not include inspection or verification of labels, identification, marking or user information. As indicated in the Statement of Work sent with the quotation, Element’s standard process is to always use the latest published version of the test methods even when earlier versions are cited in the test specification. Issuance of a purchase order was de facto acceptance of this approach. Otherwise, the client would have advised Element in writing of the specific version of the test methods they wanted applied to the subject testing.
