Power Supply Methods
The device offers three distinct power supply options:
- AA Battery Power: Open the battery cover on the back of the device and insert 4 AA batteries (not included). Ensure correct positive (+) and negative (-) polarity alignment.
- USB Power: Connect the device to a DC 5-12V USB adapter (not included) using the provided DC to USB cable.
- Vehicle Battery Power: Connect the device directly to a DC 5-12V vehicle power supply using the included cable. Attach the black wire to the negative terminal (-) and the red wire to the positive terminal (+) of the vehicle battery.
Note: When using USB or vehicle battery power, the device can operate without AA batteries installed.

Installation
For installation in vehicle engine compartments, securely attach the repellent using the provided zip ties. Position the device to maximize ultrasonic coverage and ensure it does not come into direct contact with hot engine components. For indoor use, place the device in an area where rodent activity is observed, ensuring the ultrasonic speakers are not obstructed.

Operating Instructions
Modes of Operation
The device features two primary operating modes:
- Car Mode: When installed in a vehicle and connected to the vehicle's power, the repellent automatically activates approximately 5 minutes after the vehicle is parked. It will automatically enter standby mode when the vehicle is in motion, conserving battery power.
- Indoor Mode: For use in indoor environments such as garages, attics, kitchens, or warehouses, you have the option to disable the LED strobe light function if desired, to suit the specific environment.

Ultrasonic and Strobe Functionality
The repellent emits variable frequency ultrasonic waves ranging from 9kHz to 65kHz, combined with bright LED strobe lights. These elements work synergistically to disorient and deter rodents. The ultrasonic frequencies are specifically chosen to be effective against pests while generally remaining imperceptible to humans.

Expected Results
Upon initial deployment, rodent activity may appear to increase as pests become agitated by the repellent. A noticeable decrease in rodent presence is typically observed within 1-2 weeks of continuous use, with significant reduction or complete disappearance expected within 3-4 weeks.

Maintenance
The JahyElec Rodent Repellent is designed for minimal maintenance. Periodically inspect the device to ensure there are no obstructions blocking the ultrasonic speakers or LED lights. If using AA batteries, replace them when the indicator light signals low power or when you notice a reduction in device performance. Keep the device clean and free from accumulated dust or debris to ensure optimal operation.
Troubleshooting
Device Not Activating
- Ensure the power source is correctly connected and functional.
- If using AA batteries, check their charge level and confirm they are inserted with the correct polarity.
- If connected to a vehicle battery, verify that all connections are secure and that the vehicle battery has sufficient charge.
Limited Effectiveness
- It is important to allow 3-4 weeks of continuous operation to observe significant results, as rodents require time to be fully deterred from an area.
- Ensure the device is placed in an optimal location, free from obstructions that could block the ultrasonic waves.
- For larger areas or severe infestations, consider deploying multiple units to enhance coverage and effectiveness.
Indicator Lights
Refer to the device's red/green indicator light for operational status. Consult the product diagram for the exact location and meaning of the indicator lights.
