Helen Zhao Subject: FW: RE: RE: Action Star Enterprise Co., Ltd., FCC ID: RX4AT-111B-U, Assessment NO.: AN07T6426, Notice#1- revised 1/25/2007 Dear Helen, Sorry to trouble you and please erase all previous reply. Instead, please refer to below for the answer for addressing 5Qs. Question #1: This device is subject to FCC permit-but-ask procedure. It is required to include "the answer to 7 questions" into all FM transmitter filings. Please refer the attachment for details. Please submit this document asap. Ans.: Please see attached for "the answer to 7 questions." Question #2: Please indicate what kind of antenna in "The answer to 7 questions". Ans: Done. Please see attached "the answer to 7 questions." Question #3: The test report shows 26dB bandwidth test was done at 88.3MHz only. Please provide the plots at 98MHz and 107.7 MHz. Ans: Please see the revised test report. Question #4: The test configuration shown in section 7.1 of the test report is not a correct setup. The EUT can not be tested as stand alone in bandwidth test. FCC permit-but-ask procedure specifies "Was the bandwidth properly tested with maximum audio input? Use a typical audio file from a typical device. e.g. do not use a 1 kHz signal from a signal generator. " Please redo bandwidth test with correct setting and with maximum audio input. Ans: Please see the revised test report. Question #5: FCC permit-but-ask procedure specifies "Was the tuning range properly verified? The test lab shouldindicate in the report that the tuning controls were manually adjusted to verify maximum tuning range." Please manually verify the tuning range and put a statement into the test report. Ans: Please see the revised test report page 4.
