LJL011113TTire Pressure Monitor

FCC ID: LJL011113T Dear Sir, This is to request confidentiality on information submitted for above application. We would like to request confidentiality on some exhibits we submitted for above application for the reason of trade secret. If those exhibits are available for public inspection, any person who once gets the information contained in those exhibits will be able to design and to make the same products very easily. This is a very serious problem and huge loss for us, because we did invest so much on it. Please be not made the Exhibit Types listed below routinely available for public inspection: Block Diagram and Schematics. Best regards, C.F. Huang President

Mike, Please find our explanation below: 1. Attached please find the correctted ID label. 2. There is ASIC (U1) to process the timing of transmitting. When the tire pressure is in normal range (normal mode), the interval between two transmissions is about 54.6 seconds. And when the tire pressure is over the specific range ( in alart mode, may cause dengrous situation with the car), the transmitting timing is 10ms transmission per 10 seconds and after 280 seconds will automatically reset to normal mode. 3. Attached please find the correctted test report. If you have any further questions, please let me know. Regards, K. C.
