CHART POSITION WARNING LIGHTS LIT ACOUSTIC
SCHEMA AUDIBLE WARNING DEVICE:
When I'automobiliste opens the car door to get out of his car, the device emits an acoustic signal if the car's position lights are on leftovers.
Installation of the system is extremely easy, it suffices to connect point A has the switch
of the door by the diode 1) 1 and point B on any position light. It is important to know that
the device consumes only when the car door is open and the parking lights are switched on leftovers.
For its operation, connect, at the points specified in practical scheme, a small speaker
whose impedance is between 4 and 32 ohms. The TR1 trimmer can adjust the intensity of the sound.
For mounting of components, to refer to the scheme practical implementation.
