- Line up the two round fields of view in the eyepieces until they merge into one.
- Once the target is in view, turn the eyepiece ring left or right.
- Use the ± scale on the ring to bring each eye into sharp focus.

Mount the binoculars on the dedicated-head tripod. When moving or storing them, keep the body under the protective cover.
