Frequently Asked Questions - MeoStar B1 12x50 Meopta

How to adjust the diopter correction on MeoStar B1 12x50 binoculars?

Close the right objective lens with the cap, focus on an object using the central knob. Then open the right objective and close the left one, then adjust the diopter correction knob (knob 5) until you get a sharp image. Do not touch the central knob.

Are the MeoStar B1 12x50 binoculars waterproof?

Yes, they are completely waterproof and dustproof, nitrogen-filled to prevent internal condensation. They can withstand temporary immersion.

How to use the twist-up eyecups?

Maintenance and Cleaning

Important!

1. Protect the binocular from falling and hard impact
2. Only clean the glass as recommended
3. Protect the glass with caps

All Meopta binoculars feature a robust dust-proof and water-proof design but, like any other opto-mechanical devices, they require careful handling and protection of the optical surfaces against damage. When a scope is not being used, its outer optical surfaces should be protected with the supplied caps. Dust deposited on the mechanical parts of the scope should be removed with a soft cloth; dust on the optical components should be blown off or wiped off gently with the antistatic cloth supplied with the scope. After using the binocular in the rain, thorough drying with a soft cloth is recommended.

Make sure to store the binocular in a dry, ventilated area. For storage in humid or tropical conditions we recommend to place the binocular in a case, together with a moisture absorbing agent such as silica gel.

Optical Cleaning Kit

A special Meopta cleaning kit can be purchased to clean your optical device. It contains a high-quality 2-in-1 brush, lens cloth, cleaning blower, and cleaning liquid.
