You will notice that one of the batteries and the atomizer are pre-assembled along with an empty cartridge. Simply replace the empty
cartridge with a full one by placing it firmly onto the atomizer. To
make sure the cartridge is secure, twist it slightly.
There is no on or off switch. As you press Emerald Lux to your lips and inhale, the red LED light at the tip glows like a real cigarette to let you know it's working.
For optimal performance, it is recommended that you fully charge the batteries and Emerald Lux pack before using Emerald Lux.
To charge your battery, you must first remove the cartridge and atomizer. Once you have unscrewed the atomizer from the batter, you can now screw in the batter into the USB cable. Then, attach the USB end of the cable to the electric plug. Now you are ready to charge your battery. All you have to do is plug the unit into a wall outlet.
To charge the battery using the enclosed USB charger, you follow the same steps as above up until the third image above, which is you have already removed the atomizer, and have attached the battery to the USB cable. Instead of attaching the USB end to the electric plug, you connect the USB end of the cable to your computer's USB port.
