Note: To adjust the R1 or R2 potentiometer, turn the dial clockwise until it reaches a
mechanical stop. Note the position of the arrow at the end of the slot; this is the full-
clockwise position. The dial is now ready to be adjusted. To do so, turn the dial
counterclockwise by the number of position markers specified in the appropriate table.
