aquired in 22, practically unusable, I’m very dissatisfied, I can’t use the touch screen although it has an image; no buttons work, and the button lights don’t function, power on/off no signal. Technical assistance does not seem to understand what is going on. I am very sorry that I believed in the quality of this material.
I don’t fully understand your discription but could it be in “locked” mode? Is there a “locked” indicator in the upper right corner of the screen? Check page 14 of the manual for information. If not, you may want to try a global reset. If you can still control the unit from your computer, back up your presets and global settings first so you can reload everything after the reset. Otherwise, you’ll have to rebuild you presets from scratch.
