Subject: Re: FW: Response to Inquiry to FCC (Track ing Number 734370) 12/25/2006 Bill, I am sorry for hindering you on the Christmas day. I had checked the test data again. And ensure that the field strength level of test report is the actual emission level of worst case of product. By the way , when can I receive the grant of RRDT10571-DRIVER. Merry Christmas!

They are questioning if the signals are properly searched for worst case. Please review your data, and recheck your field strength emissions results. FCC does not believe that the field strength values presented to be sufficient to work with a typical automotive FM receiver Best Regards, Bill From: Generic Office of Engineering Technology [mailto:[email protected]] Sent: Wednesday, December 20, 2006 11:13 PM To: [email protected] Subject: Response to Inquiry to FCC (Tracking Number 734370) Inquiry: Gentlemen, AmericanTCB requests guidance for FCC ID: RRDT10571-DRIVER under the “Permit-But-Ask” procedure. This device is a 15.239 12V IPOD transmitter designed to broadcast an audio signal to a car FM broadcast band receiver. The device can be manually tuned across the entire 88.1 to 107.9 MHz band. There are no external inputs available for connecting to an external analog audio source. The antenna is part of a PCB trace. Best Regards, Bill Response: The field strength levels are very low. Please request the test lab to verify that the unit tested actually works in a typical car. Do not reply to this message.

If you require more information kindly let us know at your first available opportunity. 1) How does this device operate? This device is a 12VDC IPOD transmitter. 2) Provide information on the device and its antenna. The antenna in internal and integral with this device 3) How is it installed? The device is attached to the IPOD transmitter and plugged into a cigarette lighter socket 4) What test procedure was used? ANSI C63.4: 2003 5) If tested in a car, how was it configured/tested? At the present time, FM transmitters (subject to 15.239) tested in vehicles must also be tested on a test table. Provide both sets of data. All data must be compliant The device was tested on a 3M OATS 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. The tuning is done digitally using up/down push buttons. The end user can only select 88.1 to 107.9 MHz 7) 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. The device was tested with a normal signal from the IPOD. There are no additional audio inputs. 8) Provide the test report. 2 The test report is provided.
