Safety warnings and precautions

The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.

 

 

 

 

 

 

 

THIS EQUIPMENT MUST BE GROUNDED

 

To ensure safe operation, the three-pin plug must be inserted only into a standard three-pin power outlet which is effectively grounded through normal household wiring. Extension cords used with the equipment must have three cores and be correctly wired to provide connection to the ground. Wrongly wired extension cords are a major cause of fatalities.

 

The fact that the equipment operates satisfactorily does not imply that the power outlet is grounded or that the installation is completely safe. For safety, if you are in any doubt about the effective grounding of the power outlet, please consult a qualified electrician.

The mains plug of the power supply cord shall remain readily operable. The AC receptacle (mains socket outlet) shall be installed near the equipment and shall be easily accessible. To completely disconnect this equipment from the AC mains, disconnect the power cord plug from the AC receptacle.

  • Do not place this display on an uneven, sloping or unstable surface where it may fall and cause damage to itself or others.
  • Do not place this display near water, like a spa or pool, or in a position which will allow the splashing or spraying of water onto the display, like in front of an open window where rain water may enter.
  • Do not install this display in a confined space without proper ventilation and air circulation, such as in a closed cabinet. Allow proper space around the display for dissipating heat inside. Do not block any openings and vents on the display. Overheating may result in hazards and electric shock.
  • Installation of this display should only be performed by a qualified technician. Failure to install this display properly may cause injuries to the personnel and damages and the display itself. Check the installation regularly and maintain the display periodically to ensure the best working condition.
  • Use only the accessories approved or recommended by the manufacturer to mount this display. Using wrong or unsuitable accessories may cause the display to fall and result in serious personal injuries. Make sure that the surface and fixing points are strong enough to sustain the weight of the display.
  • To reduce the risk of electric shock, do not remove covers. There are no user serviceable parts inside. Refer the servicing to qualified service personnel.
  • To prevent injuries, mounting the display is required before use.

Important safety instructions

  1. Do not use the display near water.
  2. Do not block any ventilation openings.
  3. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
  4. Do not alter the polarized or grounding-type plug. A polarized plug has two blades, one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician to replace your obsolete outlet.
  5. Protect the power cord from being snagged, stepped on, or pinched, particularly near the plug and the point where they are connected to the display. 
  6. Only use attachments and accessories specified by the manufacturer.
  7. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the display. Use caution when moving the cart and display to prevent accidents and injuries.
  8. Unplug the display during lightning storms or when unused for long periods of time.
  9. Refer all servicing to qualified service personnel. Servicing is required when the display has been damaged in any way. These instances may include when:
    • The display is dropped or an object is dropped onto the display.
    • The display is exposed to liquid, rain, or excess moisture.
    • Its power supply cord or plug get damaged.
    • The display fails to operate normally.

Notes on the display

  • To prevent the risk of physical injuries, do not attempt to lift the display alone.
  • Make sure you have four or more people available to help lift the display or a flat cart to transport the display to its final location.
  • Keep the display horizontal as much as possible.
  • Clear a floor space before unpacking.

Notes on the LCD panel

  • The Liquid Crystal Display (LCD) panel of this display has a very thin protective layer of glass which is liable to marking, scratching, or cracking if struck or exposed to pressure. The liquid crystal substrate is also liable to damage under excessive force or extreme temperatures. Please handle with care.
  • The response time and brightness of the LCD panel may vary with the ambient temperature.
  • Avoid placing the display in direct sunlight or where direct sunlight or spot lighting will shine onto the LCD panel, as the heat may damage the panel and the external casing of the display, and the bright light will make viewing the display more difficult than necessary.
  • The LCD panel consists of individual pixels to display images and is manufactured according to the design specifications. While 99.9% of these pixels work normally, 0.01% of the pixels may remain constantly lit (in red, blue, or green) or unlit. This is a technical limitation of the LCD technology and is not a defect.
  • LCD screens, like plasma display panels (PDPs) and conventional cathode ray tube (CRT) screens, are also susceptible to screen burn-in or image retention, which can be found on the screen as visible fixed lines and shades. To avoid such damage to the screen, avoid displaying still images (like on-screen display menus, TV station logos, fixed/inactive text or icons) for more than 30 minutes. Change the aspect ratio from time to time. Fill the entire screen with the image and eliminate the black bars whenever possible. Avoid displaying images in 16:9 aspect ratio over a long period of time, otherwise there may be visible burn marks on the screen as two vertical lines.
  • Under certain circumstances, condensation may occur on the inner side of the cover glass, it’s a natural phenomenon and will not affect the operation of the display. This condensation will usually disappear after around two hours of normal operation.

Notes on cleaning the display

Clean the frame when there is sign of malfunction on the touchscreen.

Cleaning the display screen

1. Before cleaning the screen, make sure the display is powered off and the power cord is unplugged.

2. Remove dust or dirt from the screen with a dry lint-free cloth. Make sure to use minimal force.

Important

Do not use paper towels or any material that may leave streaks or lint on the screen.

3. Moisten a clean, soft, lint-free cloth with 70% isopropyl alcohol.

Warning

  • Do not use hazardous chemical or ammonia-based cleaners as this may damage the surface of the screen.
  • Do not spray alcohol directly on the screen.
  • Do not fully soak the cloth in liquid. If possible, spray the alcohol onto the cloth to distribute the moisture.

4. Gently wipe down the entire surface of the screen.

Safety notice for the remote control

  • Do not put the remote control in the direct heat and humidity.
  • Do not drop the remote control.
  • Do not expose the remote control to water or moisture.
  • When using the remote control, ensure that are no objects between the remote control and the remote sensor.
