• When you attach or remove the body cap and lens from the camera, keep the lens
mount on the camera pointed downward This helps prevent dust and other foreign
matter from getting inside the camera
• Do not remove the body cap or attach the lens in dusty places
• Do not point the lens attached to the camera toward the sun This may cause the
camera to malfunction or even ignite due to the magnifying effect of sunlight
focusing through the lens
• Be careful not to lose the body cap and rear cap
• Attach the body cap to the camera to prevent dust from getting inside when no lens
is attached
