To use the Foger Switch Pro vape, follow these steps: 1. Power On: Press the power button five times in quick succession to turn the device on. The LED light will flash to indicate it's powered on. 2. Adjust Settings: If the device has adjustable wattage or temperature, use the buttons (usually located on the side) to select your preferred settings. 3. Fill the Tank: If you're using a refillable tank, remove the top cap and fill it with your desired e-liquid. Be sure not to overfill. 4. Prime the Coil: If you're using a new coil, let the e-liquid sit for a few minutes to ensure the coil is fully saturated and avoid dry hits. 5. Inhale: Press and hold the fire button while inhaling through the mouthpiece. Release the button when you're done. 6. Turn Off: To turn off the device, press the power button five times quickly again.
