should be used in Europe)
dispose according to state, local or federal law.
Do not bend, crimp or otherwise damage the power cord.
If glass is broken, handle with care.
Do not cover vent on monitor.
Do not use monitor in high temperature, humid, dusty, or
oily areas.
If monitor or glass is broken, do not come in contact with the
liquid crystal and handle with care.
Allow adequate ventilation around the monitor, so that heat
can properly dissipate. Do not block ventilated openings or place the monitor near a radiator or other heat sources. Do not put anything on top of the monitor.
The power cable connector is the primary means of detaching
the system from the power supply. The monitor should be installed close to a power outlet, which is easily accessible.
Handle with care when transporting. Save packaging for
transporting.
If using the cooling fan continuously, it is recommended to
wipe holes clean a minimum of once a month.
Please clean the holes of back cabinet to reject dirt and
dust at least once a year because of set reliability.
When using a LAN cable, do not connect to a peripheral
device with wiring that might have excessive voltage.
Connecting to a TV*
Cable distribution system should be grounded (earthed) in
accordance with ANSI/NFPA 70, the National Electrical Code (NEC), in particular Section 820.93, Grounding of Outer Conductive Shield of a Coaxial Cable.
The screen of the coaxial cable is intended to be connected
to earth in the building installation.
Immediately unplug your monitor from the wall outlet and refer servicing to qualified service personnel under the following conditions:
When the power supply cord or plug is damaged. If liquid has been spilled, or objects have fallen into the monitor.
If the monitor has been exposed to rain or water.
If the monitor has been dropped or the cabinet damaged.
If you notice any structural damage such as cracks or unnatural wobbling.
If the monitor does not operate normally by following operating instructions.
Recommended Use
For optimum performance, allow 20 minutes for warm-up.
Rest your eyes periodically by focusing on an object at least 5 feet away. Blink often.
Position the monitor at a 90° angle to windows and other light sources to minimize glare and reflections.
Clean the LCD monitor surface with a lint-free, non-abrasive cloth. Avoid using any cleaning solution or glass cleaner!
Adjust the monitor’s brightness, contrast and sharpness controls to enhance readability.
Avoid displaying fixed patterns on the monitor for long periods of time to avoid image persistence (after image effects).
Get regular eye checkups.
Ergonomics
To realize the maximum ergonomic benefits, we recommend the following:
Use the preset Size and Position controls with standard signals.
Use the preset Color Setting.
Use non-interlaced signals.
Do not use primary color blue on a dark background, as it is difficult to see and may produce eye fatigue due to insufficient contrast.
Cleaning the LCD Panel
When the liquid crystal panel is stained with dust or dirt, please wipe with soft cloth gently.
Please do not rub the LCD panel with hard material.
Please do not apply pressure to the LCD surface.
Please do not use OA cleaner it will cause deterioration or discolor on the LCD surface.
Cleaning the Cabinet
Unplug the power supply
Gently wipe the cabinet with a soft cloth
To clean the cabinet, dampen the cloth with a neutral detergent and water, wipe the cabinet and follow with a dry cloth.
NOTE: DO NOT clean with benzene thinner, alkaline detergent,
alcoholic system detergent, glass cleaner, wax, polish cleaner, soap powder, or insecticide. Rubber or vinyl should not be in contact with the cabinet for an extended period of time. These types of fluids and materials can cause the paint to deteriorate, crack or peel.

Installation

For proper installation it is strongly recommended to use a trained, NEC authorized service person. Failure to follow NEC standard mounting procedures could result in damage to the equipment or injury to the user or installer. Product warranty does not cover damage caused by improper installation. Failure to follow these recommendations could result in voiding the warranty.
Mounting
DO NOT mount the monitor yourself. Please ask dealer. For proper installation it is strongly recommended to use a trained, qualified technician. Please inspect the location where the unit is to be mounted. Mounting on wall or ceiling is the customer’s responsibility. Not all walls or ceilings are capable of supporting the weight of the unit. Product warranty does not cover damage caused by improper installation, remodelling, or natural disasters. Failure to comply with these recommendations could result in voiding the warranty.
DO NOT block ventilated openings with mounting accessories or other accessories.
For NEC Qualified Personnel:
To insure safe installation, use two or more brackets to mount the unit. Mount the unit to at least two points on the installation location.
Please note the following when mounting on wall or ceiling
When using mounting accessories, they must comply with NEC compatible mounting method.
NEC strongly recommends using size M6 screws (11-12 mm + thickness of bracket and washer in length). If using screws longer than 11-12 mm, check the depth of the hole. (Recommended Fasten Force: 470 - 635N•cm) NEC recommends mounting interfaces that comply with UL1678 standard in North America.
Prior to mounting, inspect the installation location to insure that it is strong enough to support the weight of the unit so that the unit will be safe from harm.
Refer to the instructions included with the mounting equipment for detailed information.

Orientation
When using the monitor in the portrait position, the monitor should be rotated clockwise so that the left side is moved to the top and the LED indicator light is on the bottom. This will allow for proper ventilation and will extend the lifetime of the monitor. Improper ventilation may shorten the lifetime of the monitor.
NOTE: When using the monitor in portrait position, monitor
should be used with mounting accessories.
English
LED Indicator
Mounting location
The ceiling and wall must be strong enough to support the monitor and mounting accessories.
DO NOT install in locations where a door or gate can hit the unit.
DO NOT install in areas where the unit will be subjected to strong vibrations and dust.
DO NOT install near where the main power supply enters the building.
Do not install in where people can easily grab and hang onto the unit or the mounting apparatus.
When mounting in a recessed area, as in a wall, leave at least 4 inches (10cm) of space between the monitor and the wall for proper ventilation.
Allow adequate ventilation or provide air conditioning around the monitor, so that heat can properly dissipate away from the unit and mounting apparatus.
Mounting on ceiling
Ensure that the ceiling is sturdy enough to support the weight of the unit and the mounting apparatus over time, against earthquakes, unexpected vibrations, and other external forces.
Be sure the unit is mounted to a solid structure within the ceiling, such as a support beam. Secure the monitor using bolts, spring lock washers, washer and nut.
DO NOT mount to areas that have no supporting internal structure. DO NOT use wood screws or anchor screws for mounting. DO NOT mount the unit to trim or to hanging fixtures.
Maintenance
Periodically check for loose screws, gaps, distortions, or other problems that may occur with the mounting apparatus. If a problem is detected, please refer to qualified personnel for service.
Regularly check the mounting location for signs of damage or weakness that may occur over time.

Attaching Mounting Accessories
1. Attach Mounting Accessories
Be careful to avoid tipping monitor when attaching accessories.
Mounting Interface
200 mm
500 mm
Mounting accessories can be attached with the monitor in the face down position. To avoid damaging the screen face, place the protective sheet on the table underneath the LCD. The protective sheet was wrapped around the LCD in the original packaging. Make sure there is nothing on the table that can damage the monitor.
When using mounting accessories, they must be NEC compliant and approved.
2. Ventilation Requirements
When mounting in an enclosed space or recessed area, leave adequate room between the monitor and the enclosure to allow heat to disperse, as shown below.
3. Prevent Tipping
When using the display fasten the LCD monitor to a wall using a cord or chain that can support the weight of the monitor in order to prevent the monitor from falling. Fasten the cord or chain to the monitor using the provided clamps and M4 screws.
