Annual Inspection
It is important to schedule annual maintenance visits on a digital billboard. During the
visit:
•
Replace ISP enclosure filters.
• Inspect for loose modules.
• Inspect the display for excess dust or debris.
• Use the Digital Billboard Maintenance Checklist (DD3059470) to record inspection

Note:
After performing service or completing connections, replace the display
door and ensure it is attached to the safety lanyard and secured with a
screw (#10-24 X0.625 hex head, Daktronics part number HC-1554) in the
provided location on the top-right side of each door. Refer to
replacement screws in a bag in the spare parts area.
