When I turn it on it says "power up failure, press menu key to continue". I
press the 3 keys of MEMORY DISPLAY ON/OFF part. In the past it went back to
working like a simple analog scope after a few key presses. But now I can't
get out of the acq_mode setup table.

Is there a trick to get rid of these menus and obtain a simple analog scope?
