They emit intensive sound at high audible and painful to pests but inaudible to humans. The pests will usually leave the area being protected by the ultrasound.They do not get killed.
The powerful sound waves generated by the transducers of RSCAT Repellents are within the hearing range of many pests and cause them pain and discomfort.
Sometimes they will leave the area being protected immediately, in other cases it will take as long as two to three weeks before significant reduction in infestation occurs.
RSCAT transducers are completely quiet. If you cannot hear do not thing that the unit is not working. You cannot hear ultrasound.
Aim the RSCAT unit to the wall so that the sound will ‘bounce around’ and will reflect from walls, ceiling, room contents and floor and will be present throughout the area. Since ultrasound usually does not penetrate walls, it is important that it bounces around corners to cover larger areas. Plug the R-Scat unit into a 230Volts standard wall outlet.
Extension cords may be used if necessary. The green LED will act as a breather; it will go on and off to indicate that the unit is working. Leave the RSCAT unit ON 24 hours a day.
RSCAT units are designed for indoor use. If used outdoors they should be protected from the weather. Outdoors, there are fewer possibilities for reflection of ultrasound and many things that will absorb or dampen sound, their use is limited.
RSCAT units are guaranteed for one year from the date of purchase by the user against defects in materials or workmanship.
