This machine should be installed 20~80 cm away from the ground, and it is required to be inserted into the power socket perpendicular to the ground; 2, the installation point should try to avoid carpets, curtains and other sound-absorbing materials to prevent the reduction of sound pressure to make the sound field smaller and affect the insect repellent effect; 3.
