Setup & Adjustment
Adjusting Eyecups
The twist-up eyecups allow for comfortable viewing with or without eyeglasses. Twist the eyecups up or down until you achieve a full field of view without any dark rings or shadows around the edges.

Twist-up eyecups provide customized eye relief.
Adjusting Interpupillary Distance (IPD)
The interpupillary distance (IPD) is the distance between the centers of your pupils. To adjust, hold the binoculars with both hands and bend the hinge until you see a single, clear circular field of view. The Razor UHD 10x42 has an IPD range of 56mm - 76mm.

Adjust the hinge to match your interpupillary distance.
Focusing
- Choose an object about 20 yards away.
- Cover the right objective lens with your hand.
- Look through the binoculars with your left eye and rotate the center focus wheel until the image is sharp.
- Cover the left objective lens with your hand.
- Look through the binoculars with your right eye and rotate the diopter adjustment ring (on the right eyepiece) until the image is sharp.
- Once the diopter is set, lock it in place if your model features a locking mechanism.
- From now on, you will only need to use the center focus wheel to adjust focus for different distances.

Use the center focus wheel for general focusing and the diopter for individual eye adjustment.
Using the GlassPak Pro Harness
The GlassPak Pro Binocular Harness provides a comfortable and secure way to carry your binoculars, keeping them protected and readily accessible. It includes a main compartment for the binoculars and a separate rangefinder pouch.

Care and Maintenance
Proper care of your binoculars will ensure long-lasting performance:
- Cleaning Lenses: Use the included lens cloth or a soft, lint-free cloth. For stubborn smudges, use a lens cleaning solution and a clean microfiber cloth. Avoid using harsh chemicals or abrasive materials.
- Cleaning Body: Wipe the rubber armor with a soft, damp cloth.
- Storage: Store binoculars in a cool, dry place. Avoid extreme temperatures. Keep lens caps on when not in use.
- Waterproof/Fogproof: While waterproof and fogproof, avoid unnecessary submersion or exposure to extreme conditions that could compromise seals over time.
Troubleshooting
If you encounter issues with your binoculars, consider the following:
- Blurred Image: Ensure the center focus wheel and diopter are correctly adjusted for your eyes and the viewing distance. Check for smudges on the lenses.
- Dark Rings/Shadows in View: Adjust the eyecups and interpupillary distance until you see a single, clear, circular field of view.
- Fogging: Internal fogging is rare due to argon purging. If it occurs, contact Vortex Optics support. External fogging can be wiped away.
