Nikon NIKKOR Z 400mm f/4.5 VR S Lens - Manual (Page 29)

Precautions for Use
• Be sure to support the lens when holding the camera. Failure to observe this
precaution could damage the lens and camera mounts.
• Do not pick up or hold the lens or camera using only the lens caps or lens
hood.
• Keep the CPU contacts clean.
• Should the rubber lens-mount gasket be damaged, cease use immediately and
take the lens to a Nikon-authorized service center for repair.
• Reattach the lens caps when the lens is not in use.
• Do not leave the lens in humid locations or in locations in which it may be
exposed to moisture. Rusting of the internal mechanism can cause irreparable
damage.
