Toavoid signal confusion on the two Indicators it is necessary to show onlyleft-right signals on the Trainers oscilloscope and up-down signals on thePointers oscilloscope. This is accomplished by means of cam operatedcontacts in the lobe switcher which blank the indicators during the required FIRE-CONTROL RADARS FOR NAVAL VESSELS 41 intervals. Other contacts on this assembly provide left-right and up-down image
