Cleaning ED lens
Do not use an aerosol-type lens cleaner for cleaning the Binocular's objective lenses. The quick freezing
effect of liquefied gas may break the lens. If an aerosol-type lens cleaner is used, carefully clean the
lenses by holding the can upright at least 30 cm from the lens surface while moving the can to avoid
focusing the vaporized liquid gas on one point.
• Specifications and design are subject to change without notice.
• No reproduction in any form of this "Instruction Manual," in whole or in part (except for brief quotation in
critical articles or reviews), may be made without written authorization from NIKON VISION CO., LTD.
