The protected area is over 120 square metres of unobstructed space. The Sonic Cat Repeller detects animals moving into this area and triggers a burst of continuously variable ultrasound, which sweeps a frequency range of 18,000Hz - 24,000Hz to repel them. Simultaneously, the LED indicator on the front of the unit signals that it is now activated.
The Sonic Cat Repeller is powered by two 9V alkaline batteries (not provided). Battery power is conserved by the PIR detection system, which allows the unit to remain on stand-by between activation periods, so maximising battery life.
The use of battery power enables the Sonic Cat Repeller to be easily installed in areas of your garden without mains electricity. Where mains power is available, and heavy dog or cat activity is anticipated, it is advisable to power the unit with the 5 metre Mains Adaptor.
The push on/off Test Button on the face of the unit will drop the sonic frequency to an audible range. This enables you to check that the unit is functioning properly, and to hear the swept frequency.
Position the unit using the integral mounting stake, or alternatively, mount it to a wall or building using the mounting hole at the rear of the unit.
The unit is weather-resistant.
