Operating Precautions The LCD panel and backlight have life expectancy. Due to the basic characteristics of the LCD panel, an afterimage or uneven display may occur. It is recommended that you change images occasionally, activate the power saving function, or often turn off the power to reduce the load on the LCD panel. Continuous operations of the LCD panel may accelerate the deterioration. Maintenance Screen To avoid irreparable change in appearance of the screen such as uneven color, discoloration, scratches, be careful about the following: ● Do not paste or stick anything using any glues or adhesive tapes. ● Do not write anything on the screen. ● Do not strike the screen with a hard object. ● Avoid condensation on the screen. ● Do not wipe the screen with any liquid such as water. In addition, wiping the screen with water-diluted neutral detergent or solvent such as alcohol, thinner, or benzine may affect the anti-reflection treatment of the screen. ● Do not wipe the screen forcefully. Wipe stains off the screen with a soft cloth. Ventilation openings Use a vacuum cleaner to get rid of the dust around the intakes (all the openings). If a vacuum cleaner is not available, use a cloth and wipe it off. Leaving the dust around the intakes may prevent proper temperature control and cause damage to the product. Cabinet To avoid the deterioration or damages of the cabinet such as its paint's peeling away, be careful about the following: ● Do not wipe the cabinet using solvent such as alcohol, thinner, or benzine. ● Do not expose the cabinet to any volatile substance such as insecticides. ● Do not allow any rubber or plastic in contact for a long time. ● Do not wipe the cabinet forcefully. Wipe stains off the cabinet with a soft cloth. If the cabinet gets heavily stained, wipe it with a soft cloth soaked in water-diluted neutral detergent and wrung well, then wipe with a soft dry cloth. Inserting the batteries Use two AAA dry cell batteries. Insert the batteries from the ⊖ end, making sure the ⊕ and ⊖ polarities are correct. • Follow the warnings printed on the batteries. • Battery life is about six months to one year, depending on how much you use the remote control. • The batteries we supply are only for setting up and testing your monitor, please replace them as soon as you need to. • If the remote control does not work properly, replace the batteries. • Batteries shall not be exposed to excessive heat such, as direct sunshine, fire or the like. - 7 -
