@Vape360 ... uh oh! I've been following this thread since the beginning and don't remember running into this problem. I just opened a case on the Provape ZenDesk. Here's the issue.
There is a red LED constantly on (not the button 'lighting up' that can be seen 'through/above' the top of the fire button.
The Radius is still working other wise and fires the atomizer. The fire button and up/down light up as normal. The menu is accessible and useable. I removed the battery. Obviously the red LED went out. Re-insert the battery and the red LED comes back on. I tried shutting off the display/buttons. The red LED continues to shine. The battery gauge shows about 3/4 charge. The battery measured at 3.88 volts when checked. The firmware is Ver 18.
This is my wife's Cabernet Radius and she's upset but is quite confident it will all work out. Luckily even with the problem its usable. Now she wants her blue one to ship fast as she's not looking forward to being without a Radius and I'm not so sure I'm such a loving husband to give her my Onyx.
