BRIGHTNESS

Rotate clockwise to increase the brightness; counterclockwise reduces the brightness. It is to be used in conjunction with the contrast control since its movement will also have an effect on picture contrast.
NOTE: The brightness control setting for the picture shown in Figure 2 is set too high. Set the control below this level.FIG. 2

CONTRAST

Adjust the picture for best distinction between the black and white shading. Your own vision is the best judge in setting this control properly.
NOTE: The contrast control setting for the picture shown in Figure 3 is set too high. Set the control below this level.FIG. 3

HORIZONTAL HOLD CONTROL

If the picture appears to have a tendency to move across the screen, or if it assumes a broken streaked appearance, as indicated in Figure 4, it should be readjusted to a point where the pictures remain locked in properly on all channels.
