SYSTEM OVERVIEW The RF remote control system consists of a RF transmitter and a RF receiver. The RF transmitter is mechanically integrated in the head of the key. This transmitter is used to transmit information for locking or unlocking the vehicle as also Trunk Lid/Approach Light/Panic/comfort open/Comfort Close operations by an unidirectional RF transmission line for normal remote operation by pressing a button. The information will be transmitted on the first channel and afterwards also on the second channel. 2. POWER SUPPLY The transmitter is provided with 1 Lithium battery (CR 2430) that gives a tension of feeding of +3V. The battery inversion is protected mechanically. 3. BUTTONS All buttons are on the top side of the key housing. They are arranged in the following way.
