So I have a G07 Electrohome monitor and I am getting horizontal snow lines. I know there are pots that can adjust the vertical hold/horizontal hold, but I'm leery about adjusting them with the thing on. I tried using an insulated screwdriver to turn the pots, but that didn't fit correctly. I do have a allen wrench tool. I do have a folding hex key tool with different sized bits. I'm just not sure if that would be safe to use since it's just plastic and metal. Any suggestions would be appreciated or anything to watch out for when working on it.
