7 Clean the sensor. Remove any dust and lint from the sensor with a blower. Do not use a blower-brush, as the bristles could damage the sensor. Dirt that can not be removed with a blower can only be removed by Nikon-authorized service personnel. Under no circumstances should you touch or wipe the sensor. 8 Turn the camera off. The mirror will return to the down position and the shutter curtain will close. Replace the lens or body cap. A Use a Reliable Power Source The shutter curtain is delicate and easily damaged. If the camera powers off while the mirror is raised, the curtain will close automatically. To prevent damage to the curtain, observe the following precautions: • Do not turn the camera off or remove or disconnect the power source while the mirror is raised. • If the battery runs low while the mirror is raised, a beep will sound and the self-timer lamp will flash to warn that the shutter curtain will close and the mirror will be lowered after about two minutes. End cleaning or inspection immediately. 294
