What is the pupose of the push switch on the machine?
As the Ultrasonic pest repellers are unaudible to human beings , it is at any given point impossible to know weather the machine is working properly or not, therefore we have this switch which when you will press will emit a light screetching kind of sound and you can be know that the machine is working perfectly fine.
What is the pupose of the Regulator (nob) on the machine?
The nob is often mistaken for a volume nob. It is actually a frequency nob. Set at starting level after a month move the nob slightly , next month move slightly more.. till it reaches end then start again. Basically the Rats get used to one particualr sound frequency and eventually do not run away after sometime even is the machine is On continuesly, Therefore once you change the frequency it disturbs them and they start running away.
Note: The ultrasonic pest repellers are not for repelling fly, mosquetos, cats, dogs , cattlesetc.
