3.1 Front Door

The VCO/4K front door has a lock for security purposes. Two door frame latches at the top and
two studs at the bottom hold the door in place. The front door must remain on during
system operation for NEBS EMI compliance.
The inside of the door contains an air filter made of UL 94 HF-1 foam. The removable air filter
should be regularly vacuumed to remove any accumulated dust.
To remove the front door:
1. If necessary, unlock front door. The lock is located at the center of the door between the
door latches.
2. Flip up the two door latches located to the right and left of the lock. Hold the latches
and pull the door approximately three inches away from the system enclosure. Grasp
the sides of the door and lift it up and away to clear the studs located at the base of the
enclosure.
3. Carefully remove the door and place it in an area where it will not become damaged.
