Usage of the anti barking device:
1. Switch button (double click the bark box power button twice, long press 2 seconds to shut down).
2. Test gear: Press the test switch. The device will emit 1-3 levels of ultrasonic waves in sequence. If there is no sound after pressing test mode, check that the product is fully charged.
3. The dog bark deterrent devices have a mounting hole on the back. You can make a small hole in the fence or a tree (refer to the size of the screw and expansion screw), put the expansion screw in the drilled hole, and then screw the screw into the expansion screw. Then the expansion screw will expand and get stuck in the hole. Hang up the anti barking device for dogs and it'll be stable.

Matters needing attention:
1. If the dog is deaf or hearing impaired, it may not react to the dog deterrent devices.
2. If you have used another anti barking device on your dog, it may have been adapted to ultrasound, but it may not react to a barking dog deterrent.
3. The unit is designed with provisions for hanging and should be positioned at a height of no more than 10ft(3M).
4. Anti barking devices occasionally change the position, high sensitivity, and frequency to prevent the dog from adapting; It is best not to have a large barrier between the dog barking stopper and the dog.
5. Some dogs have a two-week adaptation period, please wait patiently for two weeks to observe the dog's reaction.
6. Anti barking device can be used for about 15 days at full charge. Please charge it in time without power. Please do not use it while charging!
