AL Tech, Inc. 1F Haesung Bldg. 747-2 Yoksam-Dong, Kanganm-Gu, Seoul, 135-080, Korea www.airlinktek.com / [email protected] Page : NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits and designed to pro-vide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio of television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of more of the following measures: - Reorient of relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer of an experiences radio/TV technician for help. CAUTION: Changes of modifications not expressly approved by the manufacturer responsible for compliance could void the user’s authority to operate the equipment.

If you possible, please send me TCB Approval sheet in today. I'm sorry. Best Regards. ----- Original Message ----- From: ldy To: Mike Kuo Sent: Tuesday, February 24, 2004 9:55 AM Subject: Re: AL TECH, INC. FCC ID:PM8CARMP3AC100, AN04T3653 Dear Mr. Mike Kuo Thank you for your cooperation. I am sorry for my mistake. Question #1: Please know that USB connector cannot be connected to personal computer. USB connector of this MP3 device is connected to USB storage only. If the USB connector is connected to personal computer, if will not operate. I just think FCC Part 15 Subpart C is sufficient to be applied. If you still insist FCC Part 15 Subpart B, it needs FCC Verification not be TCB of DOC. Question #2~6: Please check the attached report file. Question #7: This MP device is not the hand-held equipment. It is installed in car before using this device. The battery you meant is the battery from cigar jack of car. Question #8: We connected test using "1KHz modulated MP3 file". Please check the attached MP3 file. If you have any question, please let me know asap.
