Sequence of work
1. Connect a sufficient length of wire to the signal terminals, the other ends of which are connected to the positive and negative terminals of the battery.
2. If there is no signal, it is defective.
3. If the signal sounds, although it did not sound in the installed state, the fault should be sought in the circuit (fuse, power button).
4. Rattling or dull sound of the alarm can be adjusted by turning the adjusting screw on the back of the alarm housing.
