1. To avoid possible problems, we can choose passive protection and active protection, try to keep the items that may cause damage to the metal signs away from the screen, and wipe the screen as gently as possible to minimize the possibility of damage.
2. Cleaning
For metal signs, the product itself is easy to wear and scratch without special treatment or adding hardener. Therefore, for general dust treatment, you can wash it with chicken feather duster or clean water, and then wipe it with soft cloth. If the oil stain on the surface is disposed, add water with soft detergent and scrub it with soft cloth.
3. Metal signs shall be placed in a low dust environment as far as possible. A large amount of dust will affect the display effect, and too much dust will damage the circuit. In case of water inflow for various reasons, please cut off the power immediately and contact the maintenance personnel until the display panel in the screen is dry.
4. Metal signs have the closest relationship with our users, so it is very necessary to do a good job of cleaning and maintenance. Exposed to the wind, sun and dust in the outdoor environment for a long time, there must be a piece of dust on the screen after a period of time, which needs to be cleaned in time to prevent the dust from wrapping the surface for a long time and affecting the viewing effect.
