7 ECO Mode

Press ECO on the remote controller to enter the backlight mode page. Press ECO to switch

among ECO, Auto and Standard.

•In the ECO mode, the power output is reduced 50%.

•In the Auto mode, the screen automatically adjusts the screen brightness

according to the light in the environment. When the light is strong, the screen

brightens. When the light is weak, the screen darkens.

•In the Standard mode, the screen brightness keeps the same.

•

Please switch off the screen when it is not used, and enable the function of Audio Only when you do not need to watch the

display, helping to reduce power consumption and save energy.

•

On the premise of ensuring viewing effect, the energy consumption can be reduced by lowering display brightness.

•

To better save energy, the automatic power-off function is congured for the screen and the default duration is 10 minutes.

If no operation is performed in 10 minutes, the screen is switched automatically to sleep mode (the same as power off) for

reducing energy consumption.

•

Check whether the PC is connected correctly to the

interactive touch screen.

The following symptoms are not faults:

・

A very few of constantly bright or dark pixels, such as tiny red, blue, green or dark points,

may exist on the LED. This symptom is not a fault and does not affect running functions of

the screen.

・

Slight sound may occur due to the backlight adjustment or ventilation. This is a normal

symptom.

・

The image and sound are normal. However, you can sense static electricity when you

touch the LED and metal back cover. This is a normal symptom.

12 Care and Maintenance

・

Do not put or install the product near a heat source or under direct sunlight, or in

dusty or humid places, or somewhere the product may be hit or damaged by mechanical

vibration. To maximize the performance, it needs to be put away from equipment such

as grid, large metal objects and radar stations as far as possible.

・

Do not wipe the screen with any chemical reagent. Solvents may damage the enclosure

or paint. If the screen is stained by dust, cut off the power and then clean the screen

using a dried cloth with a little of warm water. Use a clean soft cloth to clean the LED of

the screen.

・

Do not frequently switch on and off the product, which may shorten the product service

life. After the screen is switched off, wait for three minutes before switching it on again

If the product is not to be used for a long period of time, please power off the product

and pull out the power plug.

・

Do not maximize the brightness and contrast of the LED for a long period of time, which

may shorten the LED service life.

・

Do not use a hard object to write on the touch screen, which may scratch the LED.

The interactive touch screen uses the horizontal and vertical infrared matrix to detect

and locate the user's touch. The screen is surrounded by an infrared tube (including the

infrared acceptor and emitter), which forms an infrared net covering on the screen surface.

When a user touches the screen, ngers or other opaque objects block the infrared rays

that cross the touch point, which helps the controller detect the coordinate position of the

touch point.

Dust is easily retained on the screen surface due to its long-term exposure in the air

and causes ineffective touch or inaccurate positioning. Therefore, you need to clean the

infrared tube around the screen regularly.
