Thank you, Helen -----Original Message----- Sent: Monday, December 18, 2006 5:07 PM Subject: Gaon Int Co., Ltd., FCC ID: UP4GWT-102, Assessment NO.: AN06T6381, Notice#1 Question #1: Page 6 of the test report indicates "Occupied Bandwidth Measurement: This measurement is performed with the antenna located close enough to give a full-scale deflection of the modulated carrier on the spectrum analyzer. The EUT has audio input ports, so the input ports were connected to a Two Channel Synthesizer and audio signal was supplied with 1 kHz modulation and then the EUT was transmitted with maximum audio level." Above statement does not agree with the description in section 3.2 on page 5 of the test report: 3.2 EUT exercise Software -. The Model, GWT-100 is included a FM transmitter designed to operate on function in the 88.1 ~ 107.9 MHz. The EUT has an audio input port, so the input ports were connected to mp3 player and than the EUT was transmitted MP3 music files which was saved in MP3 player with maximum audio output level during the test. -. The EUT was tested with new internal battery and external battery condition, but the worst test data was recorded in this test report. Please explain which is the procedure that you followed to perform the bandwidth test. Please note FCC does not accept 1KHz tone to be used for this test. Best Regards, Helen 2 The items indicated above must be submitted before processing can continue on the above referenced application.
