Note

: The default preview image is set to a grey scale. To change the preview image to a color mode,

press the “Color” button once, and the preview image will turn to a color image and the “Color button”

will change to bright blue. Regardless of which preview mode is selected, grey or color, grey images

will be used for calculating the cell number displayed in the cell counting result screen.
