Isotronic M640 battery-powered high-frequency repeller

High-Frequency Battery-Powered Repeller Isotronic M640

A universal repeller for rodents and other unwanted animals. The device emits high-frequency sounds at 60-second intervals. Simultaneously, at night and dusk, it automatically emits a light sequence (flashes several times), serving as a natural permanent barrier. Animals active at night typically avoid this area. The M640 is ideal as a preventive deterrent for protecting gardens and crops or for protecting cables in the vehicle’s engine compartment. The device requires no complicated wiring as it is battery-powered (included). A built-in vibration sensor detects when the engine is started and automatically turns off, extending the operational time.

Note

This device is microprocessor-controlled and works perfectly until the power supply voltage drops to approx. 3.9 V. If the power supply voltage falls to about 3.9 V, a continuous sound/pulse tone may occur. If the ultra-high sound is clearly audible or changes to a continuous tone, check the inserted batteries' voltage and replace them if necessary.
