The remote control includes a casing (1) with four displays (2) and a push-button (3). A linear potentiometer (5) with a cursor (6) controls the power supply of the unit and the code display. The code can be selected by moving the cursor of the potentiometer. When the push-button is pressed the code displayed is transmitted to the car alarm by an IR diode. The remote control includes a twelve-bit analog digital converter connected to an EPROM (10) which generates the coded signal transmitted to a coder (12). The coder controls the diode operation. |
