Thread the neck strap or binocular harness through the strap lugs on the sides of the binocular body. Ensure it is securely fastened before use to prevent accidental drops.

The Monarch M5 features turn-and-slide rubber eyecups. Rotate the eyecups counter-clockwise to extend them for use without eyeglasses. Rotate clockwise to retract them for use with eyeglasses. Adjust until you can see the full field of view comfortably.

3. Adjusting Interpupillary Distance
Hold the binoculars with both hands and look through them. Adjust the distance between the two barrels by moving them closer together or further apart until you see a single, circular field of view. This matches the binoculars to the distance between your eyes.
Operating Instructions
1. Focusing
- Close your right eye and look through the left barrel with your left eye. Rotate the central focus wheel until the image is sharp.
- Close your left eye and look through the right barrel with your right eye. Rotate the diopter adjustment ring (usually on the right eyepiece) until the image is sharp.
- Now, with both eyes open, use only the central focus wheel to focus on objects at various distances. The diopter setting should only need to be adjusted once for your vision.

Care and Maintenance
Proper care will extend the life and performance of your Nikon Monarch M5 binoculars.
- Cleaning Lenses: Use the included Nikon Lenspen or a soft, clean optical cloth. First, gently brush away any dust or debris. Then, use the cleaning tip of the Lenspen or breathe lightly on the lens and wipe with the cloth in a circular motion. Avoid using harsh chemicals or abrasive materials.
- Cleaning Body: Wipe the binocular body with a soft, damp cloth. Do not use solvents.
- Storage: Store binoculars in a cool, dry place, preferably in their case, when not in use. Avoid prolonged exposure to direct sunlight or extreme temperatures.
- Waterproof Care: While waterproof, it is recommended to wipe off any moisture after exposure to rain or water before storing.
