The power threshold 60/f(GHz) = 60/0.190903 = 314.3 mW. The EUT output power is 43.651mW which is less than it, then no SAR test required. 2. Revised label provided. The statement have been removed. 3. Revised operation description provided. 4. These two models share the identical circuit design and the only difference is the model name and trade name. 5. The neck tie microphone is the antenna of the transmitter. Please refer to the external photo exhibit. 6. Revised circuit diagram and block diagram provided. The RX portion have been removed. 7. The test data of frequency stability vs. supplied voltage have been provided. 8. The label of receiver provided. 9. The test report has been corrected accordingly. 10. The emission mask plot and bandwidth plot have been revised with a modulated carrier signal. Please refer to revised test report. Please kindly have a review soon. Thank you in advance.

The following items need to be resolved before the > review can be continued: > > 1. Please address RF Exposure issues for the Body-worn transmitter. > If SAR does not apply to this device, please provide a justification. > > 2. The device being approved is a licensed, Part 74 Wireless > Microphone transmitter body pack. The label contains the FCC Part 15 > two-part statement, but this transmitter device is not subject to Part > 15. Please either justify having that part 15 statements on the label > or provide a replacement label with that statement removed. > > 3. The Operational Description exhibit does not provide any technical > description of the operation of this transmitter. The operational > Description exhibit typically includes the information required by FCC > 2.1033 (6) through (10): > (6) Range of operating power values or specific operating power > levels, and description of any means provided for variation of operating power. > (7) Maximum power rating as defined in the applicable part(s) of the > rules. > (8) The dc voltages applied to and dc currents into the several > elements of the final radio frequency amplifying device for normal > operation over the power range. > (9) Tune-up procedure over the power range, or at specific operating > power levels. > (10) A schematic diagram and a description of all circuitry and > devices provided for determining and stabilizing frequency, for > suppression of spurious radiation, for limiting modulation, and for limiting power. > > 4.

Please explain the difference between the 2 models. > > 5. Please provide an antenna location, description and specification > for this device. > > 6. The schematic Diagram exhibit seems to include the Transmitter > Circuit, but also the circuit for a Receiver.
