Maintenance
General Precautions
• The LED lights used in the modules are susceptible to ESD (Electrostatic
discharge). To prevent damage to the LED lights, do not touch them with bare
hands or with conductive materials when handling.
• It is recommended to regularly inspect all installed components.
•
Do not bring objects close to the ventilation holes of the display. Burns or
personal injuries may occur if any body parts are brought too close.
• Be sure to power off and disconnect all cables before moving the display. Moving
the display with its cables attached may damage the cables and thus cause fire
or electric shock.
• Power off and disconnect the power plug from the wall outlet as a safety
precaution before performing any type of cleaning or maintenance.
Initial Operation
• If a new screen has been stowed for less than three (3) months, it can be used at
normal brightness during its first use.
• If a new screen has been stowed for more than three (3) months, the brightness
should be set at 30% for its first use and allowed to operate for two (2) hours
continuously. After two (2) hours of use, power off for 30 minutes. The new
screen is now ready for normal brightness usage.
Front Panel Cleaning Instructions

cannot be removed, the LED module should be replaced.

abrasive object.
• Do not use volatile substances such as sprays, solvents, or thinners.
Cabinet Cleaning Instructions
• Do not allow water or detergent to come into contact with the surface of the
display. If water or moisture gets inside the unit, a system malfunction or
electrical shock may occur.
• Do not scratch and do not put pressure on the cabinet with any abrasive objects
of any kind.
• Do not use volatile substances such as sprays, solvents, or thinners on the
cabinet.
• Do not place anything made from rubber or PVC near the cabinet for any
