2. Setup Instructions
2.1 Unpacking
Carefully remove the repeller units from their packaging. Each unit is individually wrapped to ensure protection during transit.
2.2 Placement Guidelines
For optimal performance, consider the following placement guidelines:
- Vertical Installation: Plug the repeller vertically into a standard electrical outlet.
- Height for Flying Pests: For pests like flies and mosquitoes, install the unit approximately 30 inches (76 cm) from the floor.
- Height for Crawling Pests: For pests like mice, rats, and cockroaches, install the unit approximately 10 inches (25 cm) from the floor.
- Obstruction-Free Zone: Ensure there are no large obstacles such as furniture (sofas, refrigerators) or thick curtains directly in front of the unit, as these can block the ultrasonic waves.
- Multiple Units: For areas with severe pest activity or larger rooms, it is recommended to install multiple units. One unit is effective for up to 1200 square feet.

3. Operating Instructions
The buzzkick F339 features three distinct operating modes, indicated by different LED colors, to optimize pest repelling based on your needs.
3.1 Mode Selection
Press the power button on the unit to cycle through the modes:
- Treble Mode (Red Light): Frequency range 10kHz-15kHz, cycle period 6.4s. This mode offers stronger penetration power, effective against mosquitoes and spiders, especially in environments with soundproof obstacles like walls. This mode may be audible to humans. Recommended for use when family members are away.
- Bass Mode (Yellow Light): Frequency range 15kHz-16kHz, cycle period 25s. This mode produces an audio band that some pests like ants and mice can hear. It may be slightly audible to humans. Recommended for use when going out, or if you can tolerate a faint sound.
- Ultrasonic Mute Mode (Blue Light): Frequency range 25kHz-67kHz, cycle period 150s. This mode is effective against most pests and is generally inaudible to humans. It is ideal for use during sleep or relaxation, as it does not disturb. The ultrasonic penetration is lower in this mode compared to the other two.

4. Maintenance
The buzzkick F339 Ultrasonic Pest Control Repeller requires minimal maintenance. It is a plug-and-forget device designed for continuous operation.
- Cleaning: To clean the unit, simply wipe it with a dry, soft cloth. Do not use water or any cleaning solutions directly on the device.
- No Consumables: The device does not require refills, batteries, or any other consumables.
- Continuous Use: For sustained effectiveness, it is recommended to keep the unit plugged in continuously.
5. Troubleshooting
5.1 Initial Increase in Pest Activity
It is normal to observe an initial increase in pest activity during the first 1-2 weeks of use. This indicates that the ultrasonic waves are irritating the pests, causing them to leave their hiding spots. Activity should significantly decrease within 2-3 weeks as pests are driven away.
5.2 No Visible Effect
- Check Placement: Ensure the unit is not obstructed by furniture, curtains, or other objects that could block the ultrasonic waves.
- Verify Power: Confirm the unit is properly plugged into a working electrical outlet and the LED indicator is lit.
- Adjust Mode: Experiment with different operating modes (Treble, Bass, Ultrasonic Mute) to find the most effective setting for the specific pests in your environment.
- Allow Time: Full results may take 3-4 weeks to manifest. Continuous use is recommended.
