First, take your Hayati Pro Ultra out of the box and remove all packaging and protective stickers. Connect the included USB-C charging cable to an appropriate cable and charge the device. Although you can use it straight away, we recommend that for longevity, that the device is fully charged before use.
The Hayati Pro Ultra has tow pre-filled e-liquid tanks. Select between tanks by rotating the mouthpiece. The device is “draw activated” meaning all you have to do to activate your device is to inhale through the mouthpiece.
