This system consists of a Stand alone- type of receicer(SRx) with corresponding a RKE transmitter. SRx has implemented on board with RF generic receiver device The described system is a radio-frequency remote control for central doors locking / unlocking, trunk release and Panic activity of an automotive vehicle. This system will be a part of the equipment of the KMC GH F/L vehicles. The system is composed of the following ones: - transmitter with 4 buttons (doors locking, door unlocking, panic, and trunk release) System Operation: To serve a remote keyless entry system for the KMC GH F/L RKE system. Remote keyless entry function is provided by the RF system of the SRx and the RKE transmitter. The operation of these functions are as follows: Remote keyless Entry: The RKE transmitter transmits at 315MHz for NA an FSK modulated data signal to the SRx. The RF system of SRx receives this encrypted RF signal. The SRx send the signal to corresponding the host Body Control Module through single wired K-line bus then the host module broadcasts the requested remote commands to the appropriate control modules in the vehicle through CAN –communication line .

Test Procedure The test procedures are performed following the test stands ANSI C.63.4-2000, if applicable. 3.1 Conducted Emission Testing was performed according ANSI C.63.4-2000 in a shielded room with peripherals placed on a table, 0.8 m high over a metal floor. It was located more than required distance away from the shield room wall. 3.2 Radiated Emission Testing was performed according ANSI C.63.4-2000 at open field test site. The EUT was placed in a 0.8 m high table along with the peripherals. The turn-table was separated from the antenna distance 3 meters. Cables were placed in a position to produce maximum emissions as determined by experimentation and operation mode was selected for maximum. The frequencies and amplitudes of maximum emission were measured at vary azimuths, antenna heights and antenna polarities. Reported are maximized emission levels. Report File No. : STROR-06-015 Date of Issue : 2006-02- 06 Page : 4. Test Condition 4.1 Test Configuration The device was configured for testing in a typical fashion (as a customer would normally use it). During the tests, the EUT and the supported equipments were installed to meet FCC requirement and operated in a manner, which tends to maximize its emission level in a typical application. Conducted Emission Test It needs not to test requirement, because the EUT supplies from a DC battery. Radiated Emission Test Preliminary radiated emission tests were conducted using the procedure in ANSI C63.4-2000 clause 8.3.1.1. to determine the worst operating condition. Final radiated emission tests were measured at 3 meter open field test site. To complete the test configuration required by the FCC, the EUT was tested in all three orthogonal planes. 4.2 EUT Operation EUT was tested according to the following operation modes provided by the specifications given by the manufacturer, and reported the worst emissions. 4.3 Peripherals / Support Equipment Used Following peripheral devices and interf…
