1. How does this device operate? Answer: Power is provided by DC 3V by 2*AAA battery or DC 12V by adapter power source. Frequencies are selected by a remote controller of the EUT external device. 2. Provide information on the device and its antenna. Answer: The antenna is a built-in trace on the circuit board. (Please see the user’s manual and circuit). 3. How is it installed? Answer: Plug-in connecter is inserted into the DC 3V by 2*AAA battery or DC 12V by adapter power source. 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/tested? Answer: It is not tested in an automobile. It was tested in a 3-meter test site as shown in the Test Setup Photo. 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: Only the frequency bands (88.1-107.9 MHz, channel spacing: 200 KHz) are available. Please check Page 4 of 20 the test report. 7. Was the bandwidth properly tested with maximum audio input? The test lab should describe the audio input signal (use a typical audio file from a typical device) - DO NOT use 1kHz tone from signal generator as specified under ETSI EN 301 357-1) Answer: We play the inside MP3 files of the product with the maximum audio input. 8. Provide the test report. Answer: Please check the supplied test report document.
