You should be able to press both +/- buttons, simultaneously for 2 seconds, and get resistance, battery V, puffs and last user setting. If you hit one a bit sooner than the other or don't go the full 2 secs (as I see you've discovered ;-) ), you get the info from which ever button you hit first, or nothing. Have fun with it... they're a terrific unit.Just wanted to say I am loving my chameleon iTaste VV! It really is a gorgeous device, love the square shape and especially that it can be charged with a micro USB, since I have those everywhere around the house for charging my phone and tablet. It makes it very convenient. It has a nice solid feel and is similar in size to the 1100mah Smoktech Winder (Twist/Spinner style). The voltage +/- buttons seem a little finicky however... not sure if I'm suppose to double press the buttons to get the display to read, sometimes it doesn't respond until I press it 3 times or several times. Nevertheless, it does work and doesn't bother me too terribly since I don't need to change my voltage very often.
Edit: Nvm... looks like all I need to do is a longer press. All is good!
