Chapter1 Safety and notes

1-1 Installation notes

(1) Please don't beat or rub, scratch the surface of the LED screen heavily, don’t touch it with your hand

casually.

(2) When the screen is dirty, please clean it with absorbent cotton or cotton cloth slightly.

(3) Please clean it timely when water or other viscosity pollution fall, which may make the LED face or

color change.

(4) Please don’t make the LED screen shaked by strong external force.

1-2 Attention points of operation and using

(1) Please unplug the power cable before moving the LED screen.

(2) Please don’t change the original setting of the mainboard’s, if not, the brightness and white balance

etc. may not meet the specification.

(3) The radiation of a long time using in the room temperature is larger than the low temperature.

(4) Please note that the long displaying image may remain at the top when shutdown the machine.

(5) Please avoid the impact from the mobile phone to protect your TV.

1-3 Storage notes

(1)When stored for a long time, please keep the temperature between 0℃to 40℃,don’t expose the TV to

the strong sunlight, the humidity should be less than 85％RH.

(2)Please don’t put your TV under high humidity and high temperature environment, for example, the

temperature: 60℃, and the humidity: 85%RH.

(3)Please don’t put your TV under low temperature environment, for example, the temperature lower

than -25℃.

1-4 Dismantling notes

(1)As LED screen is easy to be damaged, while dismantle, please attention to protect.

(2)Please attention the position of each screw when dismantle, in case to beat the wrong position when

install, if not, it may lead to crack or slide of the face frame.

(3) If you need to dismantle the power board or the mainboard, please attention the position and

direction of each line, especially the direction of the screen line, in case of causing accident when install.

Before dismantle, we can take some photos of the line route for the comparison of installing.

(4)After check and maintenance, please assure that there is no foreign body in the machine when install.

1-5 High-voltage warning

The high-voltage of the LED screen is generated by the power supply board, without attention to

exposure to the high voltage, one may meet a serious electricity shock.
