Parts Overview
1. Foldable rubber eyecups
2. Diopter settings
3. Center focus wheel
How to adjust the eyecups:
If you wear sunglasses or eyeglasses, fold down the eyecups (1).
This will bring your eyes closer to the lenses thus providing an improved field of view.
How to clean:
1. Blow away any dust or debris on the lens (or use a soft lens brush).
2. To remove dirt or fingerprints, clean with a soft cotton cloth by rubbing in a circular motion.
Use of a coarse cloth or unnecessary rubbing may scratch the lens surfaces and eventually cause permanent
damage to the binoculars.
3. To thoroughly clean your binoculars, you may use a photographic - lens cleaning fluid. Always apply the fluid to the
cleaning cloth, never directly onto the lens.
Note: It is important to protect this device from dust and moisture. When using in high humidity conditions,
let the device acclimatize for a short period of time before storing so that residual moisture can dissipate.
