191.3. Error displaySee the following table for each "Error information" display and its explanation (status).Display order is q,w,e,r,t,y,u,i.Condition Status FL Display Trouble shootingqFirm CheckNGCompared with the destination settingon the board. This is displayed when themodel name or destination informationwritten into the firmware does not match.(b1)F I R M E R R O R• Please check thedestination-resistors(R2060/R2061, HDMIB'D).• Please write thefirmware of correctdestination.wGUI VersionNGError occurs in GUI version and Mainμ-com version.(b2) G U I V E R .
