Rinse the display face with generous amounts of cold water under low pressure. A
spot-free rinse agent can be used to reduce water spots.

Use soft, dry terrycloth to dry and remove any excess water. Take care not to
damage LEDs by catching the cloth on them.
7.
Allow the display to completely air-dry for 12 hours before applying power to the
display.
Dry Cleaning Process
1.
Turn off power to the display.
2.
Rub a dry, soft terrycloth towel horizontally across each row of LEDs.
3.
Make four passes per row of LEDs before moving to the next row of LEDs. Work from
top to bottom safely within reach from a lift or a stage. Take care not to damage
LEDs or the plastic louvers by catching the cloth on them.
Annual Inspection
A yearly inspection of the display should be completed to maintain safe and
dependable operation. The display will need to be opened to visually inspect the
cabinet interior and the components. Refer to the
Accessing the Internal Components
section for directions to access the interior.
• Tighten or replace any loose fasteners.
• Vacuum or carefully wipe away dust and debris around the fans and inside the
cabinet.
• Check for water intrusion or stains and replace weather stripping, tighten module
latches, place silicone sealant around areas where water might enter, and
replace damaged electronic components as necessary.
• Check the paint for cracking and peeling and touch up with rust resistant enamel
as necessary.
• Inspect the footings, tie points, and ground rods for corrosion and make sure the
structural integrity and grounding connections are intact.
A log is provided after the glossary
to track maintenance and help determine a
maintenance schedule specific to the individual display.
