Before you plug in your unit,it is important to understand sonic and ultrasonic signals
The sonic siganl is the alarm/harrassment sounda humans can hear. combining this sound with ultrasonic may give you better results for startling and repelling intruders and animals from your yard.
however,if the sonic sound bothers your neighbourhood,you can turn this off using the"sonic volume"dial,just turn the volume dial to zero.
The ultrsonic signal is the high-pitched frequency that only animals can hear,this sound will be emitted whenever your device is on(plugged in or on battery power).You can adjust the frequency using the frequency dial,but you won't urn it off by adjusting the sonic volume or frequency dial.
