# Adjusting the Size of the NavVis VLX

Adjust the size of the NavVis VLX manually to fit the operator. Size adjustment is a manual process — there is no automatic belt size selection mechanism. The device supports five sizes: XS, S, M, L, and XL. Only adjust the size if needed; skip this step if the current size already fits.

1. **Remove the screws**

With the NavVis VLX in the box, remove the two screws with the torque wrench provided.

2. **Adjust the size**

Slide the belt hook to the correct size. The device can be adjusted to the following height sizes: XS (Extra Small), S (Small), M (Medium), L (Large), and XL (Extra Large).
