Open the sliding cover and insert an EVO tobacco stick with the filter facing up and the ventilation holes aligned with the top of the device. To start the heating-up process, press and hold the button until you feel the vibration feedback. Release the button after the first vibration for Quick heating, or after the second vibration for Intense heating. The LED display shows the heat up progress - when all LEDs are lit and the device vibrates again, you may start using the device. When the heating cycle is almost finished, the device will give a short vibration. When the session is complete, the device will give a long vibration and the LEDs will extinguish. The used EVO tobacco stick may be hot immediately after use - remove it and put it in a stick tray until it cools down.
