Scope of supply:
- Unit with about 25cm cable protected with fine-wire fuse and provided with an E-Approved !!
- Two sufficiently long cable ties
- Three cable clamps for Batteriepolmontage
Function:
The unit comes with Hochfreuenztönen of 12kHz +/- 10% and developed a sound pressure level of 85dB. The beam angle is 160 degrees and the sth power consumption according to the prospectus about 7 mA. But since I have rather been measured before, after three days of non-use, the battery is all. I came to 4mA!
The test set-up brought to light that the sound of people is heard quite. For me, all subjects have him wargenommen. Ultrasound is only going from 16kHz, so is therefore not surprising that we see not merely on the basis of the lamp, that the device is working.
The device works in a rhythm about 30 seconds to, from 15s.
Because "non-ultrasound" There are half a point deduction.
Installation:
Due to the cable tie that goes quite simple, one must search a suitable location in the vehicle. I have done this on the motor back (wall interior of the vehicle) and directed the unit to the speakers down. Since the engine is front with many vehicles from the bottom with a tub, can not come from the front anyway.
Unfortunately, it was necessary to that cable to extend about 2 m to reach the front built battery. Therefore, there is also another half-point deduction. The lengthening of the cable but you do the best before installation into the car in the warmer cellar. Solder wire, isolate (heat shrink tubing), battery terminals and connect angrimpen.
I also still hang two pictures above for installation with tuned, possibly is helpful.
Test:
The device is clearly heard even above, however, when the hood is on, despite downward opening of me. I sink from this is, above rest. I go to the ear down toward wheel arches, I hear a sound on both sides of the vehicle.
Conclusion:
I did not just so equipped my Marder injured but cars equipped additional fragrance weapons in the form of peppermint scent cloth and now hope for peace. With peppermint smell in the engine compartment I had great success with the last car.
Parallel to the newly purchased device I have installed at another location a Kemo M100N. The work with real ultrasound of about 23kHz, making it really completely inaudible. Two different but are better than one, and I sit there on the two-part success of the different frequencies. ;)
I'll keep you up to date if necessary and hope the best for the car. Should it appear that contrary, I will revise the recession. This is the second car, which I display fittings with this set, the first vehicle has been 1.5 years Marder free (knock on wood).
Good luck to the little pearly whites.
