Steps

1. If the bezel has a lock, insert the key that shipped with your enclosure into the lock, and turn the key to unlock the bezel.

2. Press the two latch buttons on the bezel surface to release the bezel from the cabinet.

3. Pull the bezel off the cabinet, and put it on a clean, static-free surface.
