SETTINGS s Iris function setting 1 This should normally be set to the down (AI) position. Use a manual or fixed iris lens and set the lens aperture to the shortest F stop. Set the switch 1 to the up (EI) position. EI AI Note: Please refer to the specifications for dynamic range of the electronic iris. CAUTION: • The electronic iris is suitable for normal indoor use. When the switch 1 is set to the up (EI) position, do not use an auto-iris lens. • If used under fluorescent light, the image may flicker. In such a case, change to incandescent lighting or set the switch 1 to the down (AI) position and use an auto-iris lens. • When shooting bright subjects, pay attention to the light angle in order to avoid or minimize the smear phenomenon effect. When using an auto-iris lens (for indoor/ outdoor use) Set the switch 1 to the down (AI) position. CAUTION: If conditions are outside the electronic iris operation range or more than the maximum illumination, it will cause saturation of the CCD. In that case, use a manual iris lens. s Gain up setting 2 Switch 2 should normally be set to "NORM". If the monitoring location is dark and you would like to increase the luminance (brightness), set switch 2 to "HI". Note: If switch 2 is set to "HI", the images from the monitoring location will become brighter, but interference may become more noticeable. HI NORM 10 English
