Wilson Loke ES-HKG From: Generic Office of Engineering Technology [[email protected]] Sent: 2007 年 7 月 24 日星期二 3:36 To: [email protected] Subject: Response to Inquiry to FCC (Tracking Number 300743) 2007-7-24 Inquiry: FCC ID:AAO120313 The EUT is a FM transmitter under 15.239 from 88.1MHz to 107.9MHz. Since its operating frequency is from 88.1MHz to 107.9MHz within the band of 88MHz to 108MHz with fundamential field strength less than 48dBuV/m at 3m, it is considered fall in the scope of Category 1-15.239 FM transmitter. The test procedure plan is listed in the following: i) Radiated Emission ii) Bandwidth test 1) How does this device operate? The device is operated as 88.1MHz to 107.9MHz FM transmitter and powered by 12Vdc through cigarette adaptor. It transmit the audio signal from a external audio source such as MP3 player by a FM transmitter tuned from 88.1MHz to 107.9MHz and the audio signal can be received by a common FM Broadcasting Radio which is tuned to same transmitted frequency of the FM transmitter and regenerate the transmitted signal through the FM Broadcasting Radio. 2) Provide information on the device and its antenna. The device is a simple audio FM transmitter tuned from 88.1MHz to 107.9MHz to transmit an audio source, for example, MP3 player, to a FM Broadcasting Radio. The block diagram and circuit diagram are attached for your reference. The antenna is an integral long wire antenna accompancy with the audio input cable. 3) How is it installed? It is very easy to install. It is powered by 12Vdc thru the cigarette adaptor . Before active the device, it is connected the audio input socket to the external audio source such as MP3 player. And then, switching on the device and the FM Broadcasting Radio. And then, playing the audio from the external audio source (MP3 player) Tuning the FM broadcasting radio to the frequencies which do not occupied by other FM broadcasted channel. After that, tuning the FM transmitter to that freqnency, the audio signal from the external audio source will be heard. 4) What test procedure was used? ANCI C63.4:2003. 5) If tested in a car, how was it configured/tested? We connected the cigarette adaptor and the 12V car battery and then put the EUT on a 0.8m height turntable 3m from antenna. The adaptor, MP3 player and EUT with 10cm separated distance. The test configuration photo is attached for your reference. 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. Yes. The tuning range is from 88.1MHz to 107.9MHz. The tuning controls were manually adjusted. 7) Was the bandwidth properly tested with maximum audio input? The maximum output Level of the typical device, mp3 player is used. 8) Use a typical audio file from typical device A Typical audio file (pop music) from a typical device (mp3 player) are used 9) Provide the test report Provided. Response: Based on the test report, this device is acceptable for FCC Certification. Do not reply to this message.
