Doxmand wild animal alarms have been developed primarily for agricultural use and for disrupting wild animals. Devices generate variable ultrasound.
The key to successful wildlife alarm lies in the correct placement. It is very important that the wild animal alarm should be placed in the area to be
protected according to the characteristics of the area and the arrival direction of wild animals.
The Doxmand wild animal alarm does not guarantee that animals will not attempt to penetrate the area but will be forced to go to other areas where
they will feel better due to the annoying sound frequency, which reduces the amount of damages caused by wild animals. The sound of our product is
largely within the ultrasound range, but it can also produce lower frequencies (21 kHz to 28 kHz). Due to the sophisticated hearing of the bigger wild
animals, the sounds in this frequency range have a disturbing effect on them. In order to achieve the best efficiency, we recommend that you should
use the wild animal alarm for prevention! Alarming more than one bigger wild animal at a time is harder and more tiring than keeping a device for
prevention!
DID YOU KNOW? - What is Ultrasound?
Ultrasound is the frequency of more than 20 kHz. The average person does
not detect this range. At a younger age we hear the best, so children can
hear the high frequency. Ultrasound is used in many areas of life,
especially in medical technology (e.g., tooth scale removal, ultrasound
diagnostics) or in other fields, e.g. measurement tests, disinfection. Many
animals are able to hear this frequency, some of them are even
communicating or orientating with it.
1.1
IMPORTANT INFORMATION ON THE METHOD OF EFFECT AND APPLICATION
The Doxmand wild animal alarm does not cause the death of animals and does not cause any harm to them, unlike other wild animal alarm methods!
When the animals hear the ultrasound, they will be frightened or they will find it unpleasant, thus they will rather leave the area. If the animals notice
that the unpleasant sound is persistent, they move to another area. Until this effect prevails, it may take several days. The device must work
permanently to avoid interrupting the effect.
2. APPLICATION INSTRUCTIONS
2.1. PLACEMENT GUIDE
If you know the area and wild animal habits, you won't have to cover the entire area you want to protect.
Recommended Layouts:
Agricultural arable lands
Place it on the center of the land. You should point the speaker outward in the direction where the arrival of wild animals is most likely. If you
want to protect a wider area, you need to install more alarms. The height of the device depends on the height of the crop; it is important to place
it at least 50 cm above the crop, not to prevent the sound from spreading. FOR BETTER RESULTS, it is advisable to place 1-2 m above the crops.
Vineyards, orchards protection
Making sure that the solar cell receives sufficient sunlight and the spread of ultrasound is ensured. It is sufficient to place the device at a height
of 1-1.5 m from the ground. Note that the range is approximately 100 m, so it is advisable to place the next device within 200 m and thus continue
the installation. Of course, it has to be taken into account that ultrasound can be reflected from the trunk of trees, from vines, and they can be
diverted thus their effect can be reduced.
IMPORTANT! For both methods, the spread of sound in the air should be ensured, and do not collide with any obstacles! Since the alarm is powered by
solar energy, make sure that the solar cell is always exposed to sunlight! The sound generated by the device spreads at an angle of approximately 120
degrees from the speaker, and its intensity decreases with the distance travelled in the medium.
Of course, other successful layout methods than the above may exist due to the different features of the areas. Therefore, if the first attempt would

2.2. INSTALLATION:
To use the Doxmand VR4 wild animal alarm, follow these steps below:
1.
Survey of the area: Examination of the area to be protected, determination of the expected arrival/characteristic movement direction
of the wild animals.
2.
Positioning the device: 2.1. As described in the placement guide! Placement can be done on a grounded column/stake, making sure
that the solar cell is not covered, always exposed to sunlight, and that the free spread of the sound is not obstructed. Use the
screwdriver and screws provided to secure the device to the desired location.
Turning on: The operation of the device can be verified as follows: After turning on, the device beeps 1-3 to indicate the battery charge level and then
starts emitting ultrasound.
USER MANUAL
IMPORTANT!
Different materials conduct and absorb ultrasound in varying degrees.
This property is the acoustic resistance of the material, which is largely
related to the water content. When ultrasound encounters a solid object,
it behaves like other waves, its energy decreases due to absorption and
the spreading direction changes, even breaks or can be reflected. That is
why it is important to place the Doxmand device properly!
be unfavorable, you should try another layout.
