Sequence of works
1. Connect wires of sufficient length to the signal contacts, and connect the other ends to the positive and negative terminals of the battery.
2. If there is no signal, it is faulty.
3. If the signal sounds, although it did not sound in the installed state, the fault should be looked for in the circuit (fuse, power button).
4. The wheezing or dull sound of the signal can be adjusted by turning the adjustment screw on the back of the signal housing.
