To use your SERIES-S17 kit, firstly click the main button five times quickly. The lights around this button will flash to show that it's turned on.

Then, hold down this button whilst inhaling, and release when you finish.

Finally, click the button five times quickly again to turn the SERIES-S17 off, if it's going to be put into a bag or pocket or not used for a period of time.

If you get any gargling during use, hold the device by the battery like a fishing rod, and give it a couple of short, sharp flicks downward to clear the excess e-liquid. You will have to do this a few times with new coils as they bed in.
