The LCD screen surface is specially treated to reduce the reflection of light.
Incorrect maintenance may impair the performance of the LCD screen, so take care with respect to the following:

• Wipe the LCD screen gently with a soft cloth such as a cleaning cloth or glasses cloth.
• Stubborn stains may be removed with a soft cloth such as a cleaning cloth or glasses cloth slightly dampened with water.
• Never use a solvent such as alcohol, benzene or thinner, or acid, alkaline or abrasive detergent, or chemical cleaning cloth, as they will damage the LCD screen surface.
