From: willyauo [[email protected]] Sent: Monday, August 05, 2002 7:17 AM To: Mike Kuo Subject: Re: WA GOL INDUSTRIAL CO., LTD., FCC ID:JEBQT-20, AN02T2112 Hi Mike, Regarding your questions, please see the following reply and explanation. FCC ID JEBQT-20 Question# 1 Reply: We have modified the limit to 50mW. Please see the attachment test report. Question# 2 Reply: The tune-up procedure 10mW is wrong. Our assistant engineer typed wrong. We have corrected this. Please see the attachment tune-up procedure. Question# 3 Reply: Please see the attachment for update frequency response data in the test report. Question# 4 Reply: Please see the attachment for emission mask plots. Question# 5 Reply: The emission designator is 161KF3E. The calculation is (2M+2DK) K=1 and (2 x 32.768 + 2x 48) = 161.5kHz , so the emission designator is 161KF3E F means the Frequency modulation , 3 means a single channel containing quantized or digital information and E means Telephony(including sound broadcasting) The fourth and fifth symbols don't use. If you have any question, please advise us. We will submit the document as your request. Thank you very much.

The EUT is a frequency modulation Transmitter / Wireless Microphone with following features : Operation Frequency Range: 174MHz to 216MHz. Type of emission is 180KF3E for headset. 1. To adjust GT/MT Switch, and Gain Control, Simply push down both snap locks on the sides of battery cover and flip it backwards to expose the adjustment panel. 2. Before power on, ascertain if same channel was set up for both receiver and microphone. If not adjust to same channel accordingly. 3. The LED indicator flashes briefly when power on indicating normal battery status. If not flash occurs it has either no battery, the battery is drained or installed incorrectly. Change accordingly. 4. Plug the microphone connector into the input jack and tighten the connector screw by clockwise direction.
