1. It is critical that the top strap of the head basket be adjusted to
allow the rear section of the head basket to fit below the occipital lobe.
2. Position the v900L on your head, ensuring that the front of the
headband sits comfortably above your eyebrows and the rear of the
headband sits at the base of the occipital lobe. If the head basket sits
too high or too low on your head, repeat step 1.
3. Adjust the position of the Visi-Shield by gently raising and lowering
the support arm, using forefinger and thumb, up or down and the
Visi-Shield in or out. When properly positioned, the magnifying lens
should be in your normal line of sight. See Figure 5 on page 15.
