Professional acoustic repeller for moles and voles, 4400 mAh battery, IP65, Viano OK1

The OK-1 Mole and Vole Repeller is a state-of-the-art device designed from the ground up to effectively repel moles and voles. The repeller emits a 10-second sequence of loud sounds at 5-minute intervals in the 40–15,000 Hz range, which repels moles and voles. These animals have very sensitive hearing and therefore move out of range of the irritating noise, which causes them distress and interferes with their foraging.
Every 5 minutes, the device changes the sequence of 10-second signals to a different one so that the pests do not get used to a regular sound. The device’s electronic circuit includes a power amplifier that emits sounds through a 25W horn speaker. The device is powered by a 4400mAh (10.8V) Li-ion battery. The energy stored in the battery allows the device to operate for up to 4 weeks. After this time, the device should be charged for 24 hours using the charger included in the set. The unit is housed in a sealed enclosure with an IP65 rating.

Charging the device:
The absence of an audible signal indicates that the device is completely discharged.
You can check the repeller’s battery level (while it is in operation) by unscrewing the device’s head and checking the status of the LED indicator.
- A 1-second flash repeated every 10 seconds indicates that the device has approximately 30% of its charge remaining—the device can be recharged.
- A short flash (~100 ms) repeated every 5 seconds – indicates that the device has less than 10% of its energy remaining – the device should be recharged.
When the charger is plugged into the “CHARGE BATTERY” port, the LED will remain lit, indicating that charging is in progress. Once the battery is fully charged, the LED turns off. Unplug the power adapter (the maximum charging time for a completely discharged battery is 24 hours).
NOTE: The device should only be charged with the switch in the “I” (ON) position.

Simple installation:
1. Unscrew the top part of the repeller (the head) counterclockwise.
2. Turn on the device using the POWER switch—set to the “I” (ON) position. The device will then emit its first sound sequence.
3. Screw the head clockwise until you feel resistance.
4. For the initial installation, first make a vertical hole in the molehill using a stick or rod.
5. Carefully screw the device into the ground (Caution! Do not drive the device into the ground with a hammer or other objects!). After installation, the head should remain above ground level—the manufacturer recommends a 5 cm gap between the ground and the bottom of the head.
6. The device will operate continuously until you turn it off or the battery runs out. The absence of sound indicates that the device’s battery is depleted.
7. If the battery is discharged, connect the repeller to a 230V outlet using the charger included in the kit. Plug the charger into the ŁAD.AKU port located on the device’s head.

- A powerful acoustic transducer in the form of a 25W horn speaker emits time-varying sound sequences—once a sequence is played, the next one is different
- The device emits sounds that create an unpleasant, intolerable environment for pests, thereby preventing them from staying or settling near the protected area
- A powerful 4,400 mAh lithium-ion battery ensures the device operates for 4 weeks
- The professional, waterproof IP65-rated housing is exceptionally resistant to mechanical damage, sunlight, rain, frost, and wind
- The device is fully sealed to prevent any contaminants or water from entering the housing
- The device does not interfere with the operation of radios or electronic equipment
