2. Setup and Installation
The T3-R Ultra Rodent Repeller is designed for simple plug-and-play operation. Follow these steps for optimal performance:
- Unpack: Remove the T3-R Ultra unit and the 6-foot power cord from the packaging.
- Connect Power: Insert the small end of the 6-foot power cord into the DC input port on the back of the T3-R Ultra unit.
- Plug In: Plug the larger end of the power cord into a standard US 120-volt electrical outlet. The device is non-polarized, allowing it to be plugged in either orientation.
- Placement: Position the unit in an area where rodent activity is observed or suspected. Ensure the speakers are not obstructed by furniture, curtains, or other large objects, as this can reduce the effectiveness of the ultrasonic waves. For outdoor use, place the unit in a sheltered location to protect it from rain and water.

3. Operating Instructions
The T3-R Ultra features three operating modes to address different rodent situations. Use the mode switch located on the unit to select your desired setting:
- TRANS Mode (Green Light): This mode utilizes a single speaker to emit a "Thundering Fog Horn" sound, which is an ultra-quiet frequency designed to directly impact rodents. This mode is generally quieter for human hearing.
- ULTRA Mode (Red Light): This mode activates both large speakers to rotate through loud and aggressive ultrasonic sounds, effectively blasting and repelling rodents away.
- DUO Mode (Red & Green Lights): This combines both TRANS and ULTRA functions, providing comprehensive, rodent-repelling coverage with both types of ultrasonic sounds.
Upon plugging in the device, an indicator light will illuminate, confirming it is powered on and operating. You may hear a slight clicking or winding sound, especially in test mode, but the primary ultrasonic frequencies are generally inaudible to humans and non-rodent pets.


4. Maintenance
To ensure the longevity and effective operation of your T3-R Ultra Rodent Repeller, follow these simple maintenance guidelines:
- Cleaning: Gently wipe the exterior of the unit with a soft, dry cloth. Do not use harsh chemicals, abrasive cleaners, or immerse the unit in water.
- Placement: Regularly check that the unit's speakers are free from obstructions (e.g., dust, debris, furniture). Ensure it remains in a sheltered location if used outdoors to prevent exposure to moisture.
- Power Cord: Inspect the power cord periodically for any signs of damage. If the cord is damaged, discontinue use and contact customer support.
5. Troubleshooting
If you experience issues with your T3-R Ultra Rodent Repeller, refer to the following common troubleshooting tips:
- No Indicator Light: Ensure the unit is securely plugged into a working electrical outlet. Try plugging another device into the same outlet to confirm power supply. Check the power cord for any visible damage.
- Initial Increase in Rodent Activity: It is normal for rodent activity to temporarily increase during the first few days or weeks of use. This indicates that the ultrasonic waves are disturbing the pests, causing them to become more active as they seek to leave the area. Full results typically appear within 3-4 weeks.
- Reduced Effectiveness: Verify that the speakers are free from any objects. Ensure the unit is placed in an open area for maximum sound dispersion. Consider switching between the different operating modes (TRANS, ULTRA, DUO) to find the most effective setting for your specific pest problem.
- Outdoor Use: Confirm the unit is adequately sheltered from direct rain, snow, or excessive moisture.
