There is not that much to fiddle with the vamo, tbh
Press the big button five time to switch it on, keep the little left button pressed, it will show the battery charge and, if you keep it pressed long enough NO2 or NO1. You want it to show NO2, as the other modality output too much even at lower settings.
Pressing both little buttons for a while will switch between variable wattage and variable voltage, while resetting to the minimum output.
I rarely use it in other than variable wattage.
Just vape and up voltage or wattage until you like vapour, heat and taste, but not so high that you get bad taste.
It's really very much up to you and in any case the ideal output depends on the attie.
Vivi will not take kindly a very high voltage typically, expecially if the head is still new, so start low and back off if you taste napalm
A good alternative to the vivi is the evod.
Have fun
