Operation :

  1. Plug into electrical source.
  2. Set the "SWEEP SPEED" dial at MIN~MAX. A red light indicates the power is on.
  3. Adjust the frequency "CONTROL" knob to "RODENTS / INSECTS" ranges, the sweeping frequencies are generated to eliminate these pests.
  4. Set the "CONTROL" knob to "BIRD" range, this sound effectively repels birds, deer, coyotes, raccoons and other large wild animals. Use of "BIRD" range should be restricted around people or in residential urban environments.
  5. Each week change the " SWEEP SPEED Knob " from MIN~MAX, the pests can not get used to the sounds.
  6. The sounds may cause a somewhat unpleasant reaction to some people. You should adjust the "CONTROL" dial to a higher setting which is not audible.




  1. It should be placed at least 1-2 foot or above the ground or floor for best results.
  2. Do not place it on carpeted surfaces, behind furniture, draperies or other soft objects as they will absorb the sound waves. Coverage can greatly improved if it is aimed towards sound reflecting objects (metal, glass, concrete, marble…etc.).
  3. Do not place it near to your ears before performing this check
  4. Do not place it near to your ears before water.
  5. Order extra units if your plant or establishment is broken up with thick wall partitions which can inhibit transmission of ultrasonic sound. Order extra units if your plant has an open dock entry or exit-way where pests can gain access to premises.
  6. Please keep the device turned on day and night




In just days, you will notice an absence of rodent activity. Even the strongest strain of rodent cannot endure. Pests quickly vacate the premises to escape the intolerable sound. Perhaps you will notice an increase in insect activity during this time due to the ultrasonic sound waves driving these pests from hiding. In a short time they'll be gone also. While the pests are being driven away, they are undoubtedly leaving their eggs and larvas behind which are not affected by the ultrasonic sound waves. Incubation will continue and they'll hatch as usual. At this point, It's ultrasonic output will begin to attack these hatchling's auditory and nervous systems, driving this new generation away. In 2 to 4 weeks the infestation should be over and you'll be free of pests.
