The speed at which animals react to the disturbance from the deterrent varies. Depending on the species, this can take anywhere from a few days to a few weeks.

The solar ultrasonic animal deterrent is not always suitable for very small animals like mice and rats. They often move in hiding and may only be detected by the motion sensor at close range.

Birds cannot generally hear ultrasound and are not disturbed by it. To deter birds, operate the ultrasonic animal deterrent PRO in acoustic mode.

The sensor must be aimed at the area from which you want to deter animals. The range is 12m from the device, at a 120° radiation angle.

No! Ultrasound does not penetrate solid objects like walls, fences, trees, bushes, or garden furniture. Therefore, position the device to minimize obstacles.

To increase effectiveness, the deterrent should be positioned away from other noise sources, such as busy roads, playgrounds, etc.

Moving shadows, swaying branches, or blades of grass can trigger the motion sensor and may unnecessarily or too frequently activate the deterrent. If necessary, the sensitivity of the motion sensor can be reduced with the adjustment knob. Activation of the motion sensor is indicated by a green LED, allowing you to check the correct sensor setting.

In very rare cases, animals may become accustomed to the deterrents. Using multiple deterrents or occasionally moving the devices or alternating operation in ultrasonic or acoustic mode may help.

The ultrasonic animal deterrent PRO is a gentle method. It makes the presence in the treated area uncomfortable for the animals, but not impossible. Therefore, conditions that attract unwanted animals, such as food sources or burrows, should be eliminated. This device also has no effect on animals with impaired hearing. A 100% effectiveness guarantee cannot be given.

Do not use the deterrent in the immediate vicinity of people or pets like mice, rats, hamsters, desert mice, guinea pigs, rabbits, and ferrets.

Sensitive individuals may hear the ultrasonic waves emitted by the ultrasonic animal deterrent PRO and feel disturbed. This could also affect immediate neighbors or their pets. This should be clarified and discussed beforehand if there is any doubt.

The ultrasonic animal deterrent PRO has no effect on electronic devices such as pacemakers, garage door openers, remote controls, and similar devices

During the day, the solar cells convert sunlight into electricity and charge the batteries. Therefore, the ultrasonic animal deterrent PRO is only suitable for outdoor use and must be placed in a sunny location. Shady areas, such as under trees or in the shadow of a tall building, could lead to insufficient charging of the batteries and reduced operating time. If the sensor blinks red, it means that the sunlight has not been sufficient to charge the batteries. It is then necessary to remove the batteries and recharge them as described below.

It is best to charge the batteries in a standard battery charger before first use. If the device is not used for an extended period (for example, during winter), it preserves the batteries if they are removed from the device. Charge them before reinserting when you restart the device.

Do not use standard 1.5-volt batteries. This can cause damage to the electronics and, in the worst case, lead to battery fires.

There are repeated claims in internet forums about the alleged harmfulness of ultrasound or ultrasonic animal deterrents. These statements are false. The power of the devices is far from sufficient to cause health damage to humans or animals. Of course, the SWISSINNO ultrasonic animal deterrent PRO meets all legal limits for ultrasound sources.
