If tested in a car, how was it configured/tested? <Answer> It was not tested in a car, but it was tested in OATS and chamber, because the device does not have external antenna input port. 5.

Please refer to the statement and test data on page 12 and 13 of the test report. 6. Was the bandwidth properly tested with maximum audio input? <Answer> The device does not have audio input port, so internal 1 kHz was used for the testing and the EUT was transmitted with maximum audio level.
