2.2 Attaching the Neck Strap
Thread the ends of the neck strap through the strap lugs on each side of the binocular body. Secure the strap by feeding it back through the buckle, ensuring it is firmly attached and adjusted to a comfortable length for carrying.
2.3 Adjusting Interpupillary Distance
Hold the binoculars up to your eyes and look through them. Adjust the distance between the left and right barrels by moving them closer together or further apart until you see a single, circular field of view without any dark edges. This ensures both eyes are aligned with the optical axis.
2.4 Adjusting Eyecups
The MONARCH M7 features twist-and-slide rubber eyecups for comfortable viewing with or without eyeglasses.
- For Eyeglass Wearers: Twist the eyecups down to their lowest position to achieve the full field of view.
- For Non-Eyeglass Wearers: Twist the eyecups up to a comfortable position that allows you to see the full field of view without vignetting.

2.5 Diopter Adjustment and Focusing
The diopter adjustment compensates for differences in vision between your left and right eyes, while the central focus knob brings your subject into sharp focus.
- Close your right eye or cover the right objective lens.
- Look through the left eyepiece and rotate the central focus knob until the image is sharp.
- Close your left eye or cover the left objective lens.
- Look through the right eyepiece and rotate the diopter adjustment ring (located on the right eyepiece) until the image is sharp. The MONARCH M7 features a locking diopter to prevent accidental changes.
- Once both eyes are individually focused, use only the central focus knob for general focusing on different subjects.

3. Operating Instructions
With your binoculars properly set up, you are ready to enjoy clear and detailed observations.
3.1 General Viewing
Hold the binoculars steady and bring them to your eyes. Use the central focus knob to bring your desired subject into sharp focus. The wide field of view (up to 435 ft at 1000 yds for the 8x42 model) makes it easier to locate and track moving subjects like birds or wildlife.

3.2 Low-Light Performance

4. Maintenance
Proper care and maintenance will prolong the life and performance of your Nikon MONARCH M7 Binocular.
4.1 Cleaning Lenses
The lenses feature oil- and water-repellent coatings, which resist smudges and fingerprints. To clean, gently brush off any dust or debris with a soft lens brush. Then, use a clean microfiber lens cloth and a small amount of lens cleaning fluid (if necessary) to wipe the lenses in a circular motion. Avoid using harsh chemicals or abrasive materials.

4.2 Cleaning Body
The rubber-armored body can be cleaned with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used, followed by wiping with a clean, damp cloth. Ensure the binoculars are completely dry before storage.
4.3 Waterproof and Fogproof Design
Your MONARCH M7 binoculars are nitrogen-filled and O-ring sealed, making them waterproof up to 1 meter for 10 minutes and fogproof. This allows for reliable use in wet or humid conditions without internal fogging. While designed to withstand the elements, avoid unnecessary submersion.

4.4 Storage
When not in use, store your binoculars in their soft case in a cool, dry place away from direct sunlight and extreme temperatures. Ensure all lens caps are in place to protect the optics from dust and scratches.
5. Troubleshooting
If you encounter any issues with your Nikon MONARCH M7 Binocular, refer to the following common solutions:
- Blurry Image: Re-adjust the central focus knob. If one side remains blurry, re-perform the diopter adjustment (Section 2.5). Ensure eyecups are correctly positioned for your viewing preference (Section 2.4).
- Dark Edges in View (Vignetting): Adjust the interpupillary distance (Section 2.3) until a single, circular field of view is achieved. Also, ensure eyecups are correctly adjusted.
- Internal Fogging: The binoculars are nitrogen-purged to prevent internal fogging. If fogging occurs, it may be external condensation. Allow the binoculars to accustom to the ambient temperature, or gently wipe external surfaces with a clean, dry cloth.
- Difficulty Focusing: Check that the diopter adjustment is not locked in an incorrect position. Ensure the central focus knob turns smoothly.
If problems persist, please contact Nikon customer support for further assistance.
