The device includes a head strap with a rear dial adjustment system and an adjustable top strap. For optimal comfort: 1. Loosen the rear dial by turning it counterclockwise 2. Place the headset on your face, centered over your eyes 3. Gradually tighten the dial by turning it clockwise until the headset is secure but comfortable 4. Adjust the upper strap to distribute the weight across the top of the head. 5. Loosen the strap if you experience excessive pressure on your face. 6. Tighten the strap to further stabilize the headset. 7. Final check: the headset should remain stable during head movements but must not cause excessive pressure. Tip: The correct position for the adjustment dial is just above the nape of the neck, not on the top of the head. This ensures optimal weight distribution and stability.
