How an ultrasonic repeller works and precautions

The ZF-851 Original portable pocket size machine is recommended for outdoor use or in a large room. In elevators, storerooms do not turn on!

Its purpose is to protect a person from aggressive dogs.

The operating principle is based on radiationNo ultrasonic vibrations, the power of which exceeds the sound level of a conventional burglar alarm 120 dB. The frequency range is practically not perceived by the human ear. Dogs and some other animals easily pick up the ultrasonic wave. This causes them a state of disorientation, fear and makes them retreat.

At the same time, they do not experience pain, nothing threatens their health.

Keep in mind! If the dog is sick or has hearing problems, the device may not work.It is also ineffective in relation to animals that have undergone special training.

By the way, about training - remembering the dog's sign and voice commands of the owner. An ultrasonic repeller can also help in this matter. You just need to reduce the power of the emitter and use it at a greater distance than 12 m.

Do not test the device solely out of curiosity on your pets. This may cause a negative attitude towards you. Also don't disturb animals on the street that don't provide eel.ram. Ultrasound can provoke an unexpected reaction.

Ultrasonic Dog Chaser works in three modes:

1. Flashlight: Lock the switch in the "Light" position, and then press "ON". The light will be powerful enough to illuminate the road at night. Do not point a flashlight into a person's eyes.
2. Training: switch in "Train" position, "ON" button. Activate the device for 1-3 seconds, accompanying its operation by issuing a command.
3. Repeller: Chaser position and buttonYes "ON".

It has been noted that the device, which simultaneously emits ultrasound and light, gives a stronger effect. It is advisable to point it at a dog that is facing you. To increase the effect, slightly change the direction of the device.

-

Four prohibitions to follow:

1. Do not point the included repeller at a person's ear at close range, as this is fraught with the appearance of "ringing" in the ears and headache.
2. Do not disassemble the structure, trybefore modifying the machine.
3. Make sure that the emitter is not covered by your hand or clothing.
4. The device is not resistant to shock and water, so handle it with care.
