218 Technical Notes
Precautions for Use
• Do not pick up or hold the lens or camera using only the 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.
• Replace the front and rear lens caps when the lens is not in use.
• To protect the interior of the lens, store it out of direct sunlight.
• Keep the lens dry. Rusting of the internal mechanism can cause
irreparable damage.
• Leaving the lens in extremely hot locations could damage or
warp parts made from reinforced plastic.
• Rapid changes in temperature may cause damaging
condensation inside and outside the lens. Before taking the
lens from a warm to a cold environment or vice versa, place it in
its case or a plastic bag to slow the change in temperature.
