1. How does the device Operate? This device is operated from 88.1MHz to 107.9MHz for FM transm itting. It transmits the audio signal from an audio on the SD memory card. 2. Provide information on the device and its antenna. This device should use Cigar Jack by antenna. Any other ant ennas can not be attached to this device. 3. How is it installed? Power of this device is supplied from battery and cigar jack. Turn on the device. And after select FM transmitter . Adjust frequency with buttons on the touch screen. Set the enable button. Then this device transmits the audio signal. ( In the condition of the FM TX mode s p eaker and ear phone audio out are disabled.) 4. What test procedure was used? The power line conducted emission test was not performed bec ause this device is only powered by battery or cigar jack. The field strength of emissions was measured in accordance w ith FCC Part §15.239 and ANSI C The EUT was placed on a 0.8m high wooden table inside a shielded semi-anechoic chamber. An antenna was placed at 3m distance from EUT. 5. If tested in a car, how was it configured? The test was not performed in a car. The tests were performe d in a semi-anechoic chamber. 6. Was the tuning range properly verified? The test lab should indicate in the report that the tuning controls were manually adjusted to verify the maximum tuning range. The of this device mentions that the operating frequenc 88.1 ~ 107.9MHz. This operating frequencies were verified manually before the tests using frequency selecting button of the menu screen. 7. Was the bandwidth properly tested with the maximum audio inp ut? The test lab should describe the audio input signal (use a typical audio file fro m a typical device) - DO NOT use 1kHz tone from signal generator as specified under ETSI EN 30 1 357-1) The input audio signal was delivered internally from N4600. A nd the input audio signal level was maximum volume level of the N4600. A mp3(Rock Song) file was used for test. 8. Does the device operate in a vehicle? Please state that this was verified. Yes, this device is used in a car. This device can be powered by cigar jack and operated in a ve hicle.

AMOTECH MULTILAYER CHIP ANTENNA 1. Introduction Bluetooth chip antenna is a component which should be used with matching circuit composed of L or C. This means that you have to match the antenna with your main board to get the best performance. When you get a matching process with L or C, center frequency would be getting down to 2.45 GHz. We offer several models which have different size and center frequency, therefore you can choose the most proper one according to your board condition.
