Remove the cap from the oil container by rotating it counterclockwise.
Hold the oil container right side up and push the top into the hole in the plug-in device. Do not screw in the oil container, just gently push it in until you can hear a click, which means it has locked into place.
Plug the device into any outlet. If the outlet's natural position will cause the oil container to tip over, rotate the plug on the device to match.
Adjust the fragrance's intensity level using the dial on the device. The least strong setting is one, while five creates the strongest aroma.
Press the "X" button on top of the oil warming device to produce an extra surge of aroma whenever you'd like. Pressing the button will create a 10-minute cycle of extra fragrance.
