USER MANUAL
1. GENERAL INFORMATION
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.
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!
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
be unfavorable, you should try another layout.
For accurate placement planning, please visit the following website: www.doxmand.hu/designer!
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.

Beeps:
The states of charge indicator (first 1-3 beeps at power-on)
● 3 beeps Fully charged status.
● 2 beeps Medium charged status.
● 1 beep Low power, waiting for sunshine.
If the device is charging from an external unit, a higher frequency sound after the charge status indicator will indicate that the external charging unit is
connected.
● 3 beeps – For 12.3-14V outdoor unit
● 2 beeps – For 10.3-12.2V outdoor unit
● 1 beep – For 5-10.2V external unit
Light signals:
- When the LED is lit, the device is switched on.
- When the LED is off, the device is switched off.
IMPORTANT! The alarm is strongest with 3 beeps and weakens with 2 beeps. In the event of one beep, the device will no longer sound an alarm,
preventing the Li-ion battery cell from being discharged excessively, which would cause damage. It will reactivate after the next sunny period.
When charging externally from a 12V battery, the device protects the battery from discharging, so if the battery voltage drops below 10.2V, the device
automatically disconnects it, charging stops, thus protecting the battery from excessive discharge.
THE SOLAR PANEL CHARGES THE BATTERY ONLY WHEN IT IS TURNED ON!
If there is a protective film on the solar panel, it is advisable to remove it before using the product for the first time, as after a while the Sun may
burn it, which can make it difficult to remove and affect the proper energy consumption!
2.3 EXTERNAL SOLAR PANEL
There is a connector under the device which may connect the additional solar panel. This can be a solution for charging problems in the winter time.
When the number of sunny hours is lower or there is snow on the solar panel. Additional solar panels are not included, they are optional.
3. CLEANING AND MAINTENANCE
IMPORTANT! Do not immerse the device in water! Do not use a strong detergent, abrasive scrubber to clean the appliance! Clean the device with a
damp, soft cloth. Over time, the solar cell may become whitish and become scale-coated, affecting the power supply of the device. It is therefore advisable
to wipe it occasionally, for example by cleaning it with a recommended WD-40 or limescale cleaning agent.
4. STORAGE
IMPORTANT! When using the device periodically, please comply with the appropriate storage conditions for a longer lifetime! If the battery charge is too
low or too high, you can shorten the battery life. Its storage temperature is recommended between (-)20 and (+)25 °C. Always turn off the device when
not in use, store it in a closed environment!
Before putting it on the shelf, it is recommended to clean the device as described above. Check the battery charge! Turn it off and then on again to see
how many beeps you hear when you turn it back on. The device should be stored with a medium charged battery, so you should hear exactly 2 beeps
when you turn it back on. If you hear exactly two beeps, turn it off and you can put the device away.
If you hear 3 beeps, cover the solar panel while it is on and after a few hours try to turn it on and off again. Repeat until you hear 2 beeps when turning
on. If you only hear one beep, put it to the sun when it is turned on and let it charge. After a few hours try to turn it on and off again. Repeat until you
hear 2 beeps when turning on.
5. TROUBLESHOOTING
Before contacting a service center, please check the following options:
PROBLEM POSSIBLE CAUSE POSSIBLE SOLUTION
The effect of the alarm is weakened.
Low battery level (1 beep).
The solar cell is not exposed to sufficient
sunlight.
The battery is only charged when the device is
turned on!
It is recharged to the appropriate level with
sunlight, but if it still gives you only 1 signal,
contact our customer service.
