Maintenance and Storage

Care and cleaning of the lens

  • Use a blower, can of air, or soft oil-free brush to remove dust from the lens surface.
  • Fingerprints and other substances left on the lens surface can cause mold growth. After removing dust, lightly wipe the lens with a soft lens cloth, gauze, or cleaning paper (available at a camera shop) dampened with a small amount of lens cleaner. Wipe the lens surface gently in a circular motion, starting from the center and working out to the edge. If the lens surface is still dirty repeat the process again, using a new piece of cleaning paper or an unused portion of the cloth. After this, use the moisture from your breath to fog the lens and wipe it clean, using a new piece of cleaning paper or cloth.
  • A commercial lens cleaner can leave behind a film on the lens surface so use as small a quantity as possible.

How to clean the body

  • Remove dust and debris with a blower or can of air and wipe with a clean soft cloth. Do not use solvents such as acetone, benzene, paint thinner, or products that contain these solvents to clean the body. These products can discolor or deform the outer surface of the body.
  • Carefully brush dirt and debris from the focus knob, sliding hood, and other moving parts.

Storage

  • Storing the spotting scope without cleaning can leave stains on the surface and promote mold growth. Cleaning is especially important after using the spotting scope in dusty or humid conditions, or after use in the rain or near the coast.
  • After cleaning, allow the spotting scope to dry thoroughly indoors at room temperature, replace all lens caps, and then store the spotting scope in a dry place. Place the spotting scope in an airtight container together with desiccant when storing for extended periods of time.

Safety Precautions

Warning!

  • Never look at the sun. Severe eye damage could occur up to the permanent loss of eyesight.
  • Make sure that small pieces and packaging such as eyepiece caps, covers, plastic bags etc. are out of the reach of children. If such an item is swallowed, serious injury, suffocation, or death could occur.

Caution!

  • Set the spotting scope correctly, otherwise it may fall, causing damage or injury.
  • Do not place the spotting scope in an unstable location. If it falls or tips over, injury may occur.
  • Do not leave the product in direct sunlight. Fire may occur.
  • Do not leave the product near open flames, inside a car, or in any place where extreme temperatures may occur. This can cause optical damage and lead to the failure of waterproofing.
  • Skin inflammation or irritation may occur by long term contact with rubber parts. If such a condition occurs, consult a physician.
  • When using the spotting scope in an urban setting, make sure that you do not disturb the privacy of others.
  • This product is waterproof which allows for use in the rain. However, immersion in water and use of the focus knob when wet should be avoided whenever possible.
  • Do not attempt to repair or open up the spotting scope body. This will void the warranty.
