Ultrasonic Repeller for Car - Ultrasonic frequency 12 kHz - 25 kHz - Connection to a 12 V car battery - Protection against martens - Animal repellent - With 3 flash LEDs [Class ene

Working Principle: Changing the intervals of the ultrasonic frequency conversion output reduces the hearing resistance of the mouse, and the LED light keeps flashing to expel the mouse and prevent rodents like mice from biting the wire. Durable with variable ultrasound and thus protects against costly engine damage on the car.Operation process: 1-15 seconds, the red light flashes 3 times, then the 12K 25kHz ultrasonic wave is emitted, accompanied by the white LED flashes. 16-30s, ready to use. 31-50s, repeat process for 1-15s. 51s-1min 10s, ready to use. 1 min 11 sec 1 min 40 sec, repeat 1 to 15 seconds.

When the car starts, our device will automatically enter sleep mode and stop working.5 minutes after the car stops, the work mode is activated to protect the car from pests such as mice. Low voltage battery detection function: The product detects the battery voltage during operation. If the battery voltage is lower than 9.2V, the product will alarm and stop working to avoid battery power failure. When the battery voltage is restored, the alarm will automatically stop and go to sleep.Easy to install: When installing, simply connect the two plugs of the power cable to the positive and negative poles of the car battery and secure it with the cable ties provided.
