An Intractable Problem

We have received a call for assistance from reader Simon Bagg, who is experiencing some trouble with his trusted AOR AR7030. Following a recent filter calibration through the Configuration menu, the sequence failed to complete, and instead, the LCD readout just stated ‘CPU???’.

I have checked this on my own AR7030 and could not find a solution. Suggestions to the editor at the usual e-mail, please, I will pass them on to Simon.
