- Insert Fuel Cartridge: Remove the cap from the fuel cartridge. Insert the fuel cartridge into the opening at the bottom of the repeller and twist until it clicks into place.
- Activate Device: Slide the ON/OFF switch to the 'ON' position. Press the 'START' button 2-3 times quickly.

4. Operation
Once activated, the Thermacell Mosquito Portable Repeller will begin to create its protection zone. For optimal performance:
- Placement: Place the repeller in the center of the area you wish to protect.
- Zone Formation: Allow approximately 15 minutes for the 15-foot protection zone to fully form.
- Windy Conditions: On windy days, place the repeller upwind of your location so the repellent is carried towards you.

6. Troubleshooting
If your Thermacell Repeller is not performing as expected, consider the following:
- No Orange Glow: If the view window does not show an orange glow after pressing the 'START' button multiple times, ensure the fuel cartridge is properly inserted and has fuel. The igniter might also need to be pressed more firmly or repeatedly.
- Mosquitoes Present: Ensure the repellent mat is not white (indicating it's used up) and that the fuel cartridge is not empty. Check if the device has been on for at least 15 minutes for the zone to form. Strong winds can also reduce effectiveness; try placing the unit upwind.
- Device Not Heating: Confirm the orange glow is present. If the device is lit but not heating the mat, the internal heating element may be obstructed or faulty.
