YHEP2798FM TRANSMITTER

1. How does the device Operate? Answer: Power DC 3V is provided by battery. Frequencies are selected by a UP/DOWN button on the EUT. Set the adjust frequency, and then the music can be transmitted out. The frequency range from 88.1MHz to 107.9MHz. 2. Provide information on the device and its antenna. Answer: The antenna is a built-in trace on the circuit board. (Please see the attached: user manual and circuit) 3. How is it installed? Answer: Plug the audio terminal, then input the audio signal. No other installation is required. 4. What test procedure was used? Answer: ANSI C63.4-2003. 5. If tested in a car, how was it configured? Answer: It was not tested in an automobile. It was tested in an 3 meter chamber as shown in the Test Set-Up photographs. 6. Was the tuning range properly verified? The test lab should indicate in the report that the tuning controls were manually adjusted to verify maximum tuning range. Answer: The maximum tuning range is 88.1MHz to 107.9MHz. Test is selected with Lowest(88.1MHz), Middle(98.1MHz), and High(107.9MHz) channel. Please see the test report (Page 3 of 17 and the data showed) and Usermanual. 7. Was the bandwidth properly tested with maximum audio input? Answer: We played a song from audio signal with the maximum audio input. 8. Provide the test report. Answer: Please refer to the attachment.
