January 31, 2007 RE: Enping Ding Li Acoustics Technological Co., Ltd. FCC ID: RW5UH101 Below words with blue is my reply, Confirmed with the manufacturer again that they needn’t confidentiality. Please see revised report. Please see revised P8 and P9 of the report. The highest emission was found when microphone’s antenna aim at receive antenna. The set-up photo is only for reference. Understand! Be careful in the future.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 January 31, 2007 RE: ENPING DING LI ACOUSTICS TECHNOLOGICAL CO., LTD FCC ID: RW5UH101 I have a few comments on this Application. Depending on your responses, kindly understand there may be additional comments. 1.) Kindly confirm in writing if Confidentiality will not apply to any Exhibits in this filing. 2.) Kindly remove all references to ANSI C63.4 from this filing. The correct reference for any Licensed transmitter is EIA/TIA 603. ANSI C63.4 is specifically for Unlicensed low power transmitters and Unintentional radiators 3.) Refer to your radiated power test on page 8 of the Test Report. Kindly provide all details on the substitution method including cable loss, ACF, and signal generator levels. 4.) During testing for both Tx radiated power, and Tx radiated spurious emissions, was the EUT rotated across three orthogonal planes? 5.) FYI: All Licensed transmitters should never use QP or CISPR bandwidths for any radiated measurements. Use of QP and CISPR bandwidths is primarily designed for IT equipment. For this case, it probably will not mater in the suitability of this device for Certification, but it still should not be used. William H.

Product Operation Description This product UH-101 is a handheld wireless microphone, which has one switching key for power on/ off. The product UH-101 equipped two indicators on the switching keys: one would light when the power switching keys were on, the other would light when the power is low. The main function of UH-101 is transferring audio signal to electric signal via micro, the input electric signal were deal with frequency modulated, amplified and transmitted the radio signal to relative receiver. The RF signal of transmitter is generate by the Voltage Controlled Oscillator(VCO), after the RF-Power Amp circuit ,the power of the RF signal can be amplified , and then it can be transmitted by the antenna. The VCO is controlled by the PLL (Phase Locked Loop) circuit via the Low Pass Filter(LPF). The Reference Oscillator circuit (Reference OSC) generate the reference frequency single (fr single), and the frequency depend on the crystal. A part of the VCO output RF signal is feedback to the PLL, the RF signal frequency will be divided to the low frequency single(fp single). And the divid ratio can be programmable via the MCU. The fp single compare with the fr single in PLL circuit, PLL output the voltage signal to control the VCO to adjust the RF single frequency, till the frequency for fr signal and fp signal are equal. So the VCO can output variable frequency RF signal via set the divide ratio in PLL. Correspond the wanted channel RF frequency, the divide ratio is preset in MCU memory. When the user set channel with DIP Switch (Channel Selector), the MCU will obtain the corresponding divide ratio and send to the PLL. Then the PLL control the VCO to work in the channel frequency. The audio after compress is summing with the Tone Code signal ,input to the VCO circuit. It will be modulate by the RF signal via a Variable Capacitance Diode within the VCO circuit.

Tune Up information for Wireless Microphone UH-101 The frequency change is only through trimming of discrete components (capacitorsC50, C82, C84, C56, VC2), which is relating to frequency and within the circuit. -------By the manufacturer to change the frequency band. Turn the frequency agile rotary DIP switch to select one of the sixteen channels. --------By the user to select frequency channel, follow the manual. The user can not tune the transmitter outside the allowable US frequency ranges of 730.05MHz to 759.95MHz, 760.05MHz to 789.95MHz and 790.05MHz to 805.95MHz.

Band III: 790.05-805.95MHz All the 3 versions are technically identical except the following items:
3 different programmed frequency ranges
PCB. The boards are similar. On the PCB, the values of some capacitors are different. To find out the worst case channel, the radiated field strength and the spurious emissions have been tested. All other remaining tests have been performed on the worst case channel. The reason for this was, that there was no influence recognizable measurement of frequency error and channel bandwidth over each band. Summarizing: The complete measurement have been performed on the following 3 versions:
