5. Notes to users Power supply Connect a 9V DC voltage (8.5 to 9.5V) from an external regulated DC power supply. Use a stable power supply without ripple and noise. Prior to turning on the power switch , check that the polarities of the power cable are correct , referring to the connection diagram (Page 11 , 12) To protect CCD (sensor) Do not touch the glass surface of the CCD sensor to avoid deterioration in picture quality due to dirt and scratches. If the glass surface of the senso

5. Notes to users Phenomena inherent to CCD imaging device Following are phenomena inherent to a CCD imaging device , and not defects. Smear and blooming When strong light (lamp , fluorescent lamp , reflected light , etc.) is shot , pale bands are displayed vertically above and below the light. In this case , change the angle of the camera so that such strong light does not enter the camera through the lens. Fixed pattern noise When the camera is operated in a high temperatur
