Environmental and Safety Protection
Ensure operating temperature and humidity remain within the ranges of -20°C to 40°C and 10% to 90% RH; install temperature control and dehumidification equipment if thresholds are exceeded.
Power off and cease operation during severe thunderstorms, heavy rain, or high winds to prevent safety incidents caused by lightning strikes or water ingress.
Do not place corrosive gases or flammable/explosive materials near the display unit, and keep it away from sources of strong electromagnetic interference.
Cleaning Procedures
Completely disconnect the power supply before cleaning and allow the display unit to cool down fully before proceeding.
Do not use highly corrosive solvents such as alcohol or gasoline; use only neutral cleaning agents with a soft, lint-free cloth for gentle wiping.
Do not wipe modules directly with a wet cloth to prevent liquid from seeping inside and causing short circuits.
Operational Restrictions
Avoid displaying high-brightness solid colors (such as pure white or pure red) for extended periods; limit continuous display of such images to no more than 30 minutes.
Non-professionals must not touch internal wiring to avoid electric shock or damage to precision components.
If the unit remains idle for more than 7 days in a high-humidity environment, preheat it at 30%–50% brightness for 4–8 hours before resuming normal operation.
