Choose a range that best reects the type
of animal you are trying to repel. Insects
and large animals are repelled by lower
frequencies (counter-clockwise). Rodents
are repelled by higher frequencies (clock-
wise)
Ultrasonic signals travel in a forward
direction. You will need to point the device
towards the area where you are having
the pest problem. The signal will range
170 degrees horizontally and 60 degrees
vertically from the unit
Note: If you have a cat or a dog you may
have to turn the device off when they are
in the yard. This depends on the frequen-
cy you are using because cats and dogs
can have very different levels of hearing
depending on age or size. Other types
of pets such as rodents or insects may be
more sensitive. Ultrasonic waves cannot
penetrate surfaces, so put them in a box or
leave them behind and out of range of the
device
