     (4) Always check the generator output voltage. Voltage is too high will burn horn contact, low voltage (below the speaker's rated voltage) speakers will emit abnormal sounds.
     (5) Wash, rinse water can not be directly megaphone to avoid leaving water into the speakers do not sound the horn.
     (6) in the maintenance of the speaker, should pay attention to the position of each metal pad and insulation pads, non-installed wrong.

     4, if the speaker does not sound completely, first check to see if the fuse blows, then unplug the speaker plug, measured with a multimeter here when the horn switch has power. If there is no power, check the speaker wiring harness and horn relay; If there is power, it is the speaker itself is the problem, then you can try to adjust the adjusting nut on the horn to see if sound, if you still do not ring, you need to replace the speaker.
     5, if the horn chirp boring, there is likely to be the speaker's own fault, then just knocked speakers, most of them can be improved. Other reasons are poor contact, especially around the steering wheel lines, the use of frequent, easily lead to wear and tear.
     6, Mifengbuyan easy to damp, although the internal speakers is closed, but if Mifengbuyan went to the car wash, easy access to the interior space of airborne mist or water vapor, water vapor will likely cause damp contacts does not work .
     7, the work of the speaker in the car low, and the work on the battery, if the battery's energy is reduced, then the sound of the horn is also reduced, to check the battery charge capacity is normal.
     Daily use of car horns note:
     1 Remember when washing to prevent the speakers get wet, dry as soon as the water found in the horn with air gun.
     2 Try not always long honk the horn contacts so easily lead to premature ablation.
     3 speaker fails try to seek professional help repair technician, do not blindly replace the speaker, likely to cause unnecessary waste.
