How To Use?

  • STEP1. Install Battery

    Open the battery cover and insert a CR2 battery, noting the positive and negative poles.
    If a low battery prompt (e.g., “LOW” or a flashing battery icon) appears on the screen after powering on, replace the battery promptly. Replace the CR2 battery at least once a year as recommended.

  • STEP2. Adjust Eyecups

    Without Eyeglasses: Fully twist up the eyecups to ensure a complete field of view.
    With Eyeglasses: Twist down the eyecups to reduce the distance between eyes and eyepieces, preventing view obstruction.

  • STEP3. Adjust Interpupillary Distance

    Hold both sides of the binoculars and move the barrels left/right to align the centers of the left/right eyepieces with your pupils.
    Complete the adjustment when a single, ghost-free image is seen (IPD should match your personal eye spacing).
