1. Installation Requirement
Bearing
You can choose the portable or a wall-mounting method according to your needs. The wall
mounting can substantially save the space.
If you choose portable mounting, use the mounting rack or support. If you want to use a selfmade
mounting rack, the bearing capacity of the rack should be at last four times of the display weight.
The bearing capacity of the mounting support must be four times of the actual weight of the display to ensure steadiness of the interactive display.
When you choose wall mounted, the bearing capacity of the mounting surface must be at least
four times of the weight of the display. When the mounting surface is a wall or ceiling of a building, the wall must be built with solid ricks, concrete or materials of equal intensity. If you need to
mount the display on a loose surface such as an old brick wall, wood plank wall, solid wall, metal
or non-metal structure wall or a wall with a thick decoration layer, take necessary consolidating
measure to ensure that the display is steadily mounted.

Caution
• Please switch off the display 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 configured for the display and the default duration is 10 minutes. If no operation is performed in 10 minutes, the display is switched
automatically to sleep mode (the same as power off) for reducing energy consumption.
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%.

• Do not share the power socket of the display with the electric appliance
that causes interference.
• Change the batteries.
• Clean the signal emitter at the top of the remote controller. (Check
whether it is blocked.)

Solution
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 display.
• 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
Maintenance Tips
• 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 display with any chemical reagent. Solvents may damage the enclosure or paint.
If the display is stained by dust, cut off the power and then clean the display using a dried cloth
with a little of warm water. Use a clean soft cloth to clean the LED of the display.
• Do not frequently switch on and off the product, which may shorten the product service life. After
the display 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 display, which may scratch the LED.
Clean the Infrared Tube
The interactive display 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, fingers 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.
