Ultrasonic Car Repellent - Ultrasonic Frequency 12 kHz - 25 kHz - Connects to a 12V Car Battery - Protection against Martens - Animal Repellent - With 3 Flashing LEDs [Energy Class]

Product Information: Operating Principle: The changing intervals of the ultrasonic frequency conversion output reduce the mouse's hearing resistance, and the continuous flashing LED light repels the mouse and prevents rodents like mice from chewing the wire. Durable with variable ultrasonic waves, it protects against costly engine damage to the car. Operating Process: 1-15 seconds: The red light flashes 3 times, then a 12K 25 kHz ultrasonic wave is emitted, accompanied by a flashing white LED. 16-30 seconds: Ready to use. 31-50 seconds: Repeat the 1-15 second process. 51 seconds-1 minute 10 seconds: Ready to use. 1 minute 11 seconds, 1 minute 40 seconds: Repeat the 1-15 second process. Stop after the above steps for 1 minute. Repeat the above steps twice and maintain the process for 3 or 5 minutes. When the car starts, our device automatically enters standby mode and stops working. Five minutes after the car is turned off, the working 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 drops below 9.2V, the product will sound an alarm and stop working to prevent battery drain. When the battery voltage is restored, the alarm will automatically stop and the device will enter standby mode. Easy to install: During installation, simply connect the two plugs of the power cable to the positive and negative terminals of the car battery and secure them with the included cable ties. It also features reverse connection protection to prevent damage to the product from improper circuit connection.
