③Adjust Focus regulating wheel and diopter regulating wheel until the objects clearly shown;

④Short press Palette button, after display screen goes black, press Palette button again to calibrate Shutter.

Note: Environment factors (such as Focal length, Emissivity, etc.) will affect the definition of images, you can repeat the above steps before taking photos every time.
