3) If the picture quality gets worse in step (2) above by increasing the L.O., the following procedure should be
implemented.
Move the lst and 2nd DIP switch to the UP position and the 3rd DIP switch to the DOWN position. This
moves the L.O. down by 0.25MHz. If the picture quality improves, try putting the lst position in the DOWN
position, leaving the 2nd switch in the UP position and the 3rd switch in the DOWN position. Determine which
position gives better quality and activate the AFC switch.
