The interpupillary distance (the distance between the centers of your pupils) must be set correctly to see a single, circular image.
- Tenez les jumelles près de vos yeux.

- Regardez à travers les jumelles avec votre œil gauche vers un objet éloigné.
- Rotate the central focus wheel until the image is sharp for your left eye.
- Fermez votre œil gauche ou couvrez l'objectif gauche.
- Look through the binoculars with your right eye at the same distant object.
- Adjust the diopter ring (usually on the right eyepiece) until the image is sharp for your right eye.
- The diopter setting is now calibrated for your eyes. You should only need to use the central focus wheel for subsequent observations.
4. Fonctionnement
4.1 Mise au point
