Cover the lens surface using a black sheet of paper, etc. so that light does not enter the lens. 3. Press and hold the SPOT CORRECTION button on the unit for more than 2 seconds. * White-spot correction will start. Correction may take several seconds for completion. Notes • Maximum correction: less than 16 to 32 spots • The white-spot correction feature of this unit does not guarantee the correction of all white spots. Depending on the characteristic of white spots, correction may not be possible. • When performing white-spot correction, accurate data may not be achieved in case of highly detailed pixels since correction is made using the information of surrounding pixels. • The result of white-spot correction is maintained until the next correction is performed. 26
