[. . . ] Do not use organic solvents, such as thinners, alcohol or benzine to remove stains from the lens. [. . . ] After reading this Operating Instructions, keep it for future reference. For your safety on use of a lens Before operating, pay special attention to the following remarks. When images are too dark, too bright or there is no image, make the adjustment according to the following table. LEVEL may not be lowered in some cases due to backlight compensation and AGC features of the camera being switched on. ⷠWhen the AGC of the camera is switched on, there are some instances where the level does not alter and the image quality deteriorates, even when the "LEVEL" adjustment variable resistor is turned all the way to "L" side. Turn the "LEVEL" variable resistor towards "H" until the image quality improves. If the lens emits smoke, smells of smoke or gives off heat, discontinue use immediately. The lenses having CE marking on their bodies are conformity with the standards EN50130-4 and EN55022 related to EMC directives by EU.
