Recommended Use & Maintenance
Recommended Use
Ergonomics
To realize the maximum ergonomic benefits, we recommend the following:
•For optimum performance of the monitor, allow 20 minutes for warming up. Avoid reproduction of still patterns
on the monitor for long periods of time to avoid image persistence (after image effects).
•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.
•Adjust the monitor’s brightness, contrast and sharpness controls to enhance readability.
•Get regular eye checkups.
•Use the preset Size and Position controls with standard input signals.
•Use the preset color settings.
•Use non-interlaced signals.
•Do not view the primary color blue on a dark background. It is difficult to see and may cause eye fatigue due
to insufficient contrast.
Maintenance
Cleaning the LCD Screen
•When the LCD screen is dusty, please gently wipe with a soft cloth.
•Clean the LCD screen surface with a lint-free, non-abrasive cloth. Avoid using any cleaning solution or glass
cleaner!
•Please do not rub the LCD screen with a hard or abrasive material.
•Please do not apply pressure to the LCD screen surface.
•Please do not use OA cleaner as it will cause deterioration or discoloration on the LCD screen 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.
•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.

does not cover damage caused by improper installation. Failure to follow these recommendations could result in
voiding the warranty
Mounting
For customer:
CAUTION
DO NOT mount the monitor yourself. For proper installation it is strongly recommended to use a trained,
qualified technician. Please contact your supplier, as they may be able to provide a list of qualified installation
professionals. Mounting on a wall or ceiling and hiring a technician is the customer’s responsibility.
Maintenance
•Periodically check for looses screws, gaps, distortions, or other problems that may occur with the mounting
equipment. 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.
DO NOT block ventilated openings with mounting accessories or other accessories.
For NEC Qualified Personnel:
Stability Hazard.
The device may fall, causing serious personal injury or death. To prevent injury, this device must be securely
attached to the floor/wall in accordance with the installation instructions. Carefully inspect the location where the
unit is to be mounted. Not all walls or ceilings are capable of supporting the weight of the unit. Weight of this
monitor is mentioned in Specification (ME431 IR, ME501 IR & ME551 IR). Product warranty does not cover
damage caused by improper installation, remodeling, or natural disasters. Failure to comply with these
recommendations could result in voiding the warranty.
To ensure safe installation, use two or more brackets to mount the unit. Mount the unit to at least two points on
the installation location.
NOTE: To achieve optimum performance of touch technology, monitor must be correctly leveled. Only straight
upright and titled back position of the monitor is acceptable. Monitor tilted to front will result in convex position of
the glass and might negatively influence the touch performance.
For further instructions, please refer to standard user’s manual of the base model monitor ME431,
ME501 & ME551.

Connections (1/2)
NOTE: Do not connect or disconnect cables when turning on the monitor’s main power or other external
equipment’s power as this may result in a loss of image.
NOTE: Do not use an attenuating (built-in resistor) audio cable. Use an audio cable without a built-in resistor.
Using an audio cable with a built-in resistor will lower the sound level.
Before making connections:
•Turn off the device’s power before connecting it to the monitor.
•Refer to the device’s user manual for available connection types and instructions for the device.
•We recommend turning off the monitor’s main power before connecting or disconnecting a USB storage
device or a microSD memory card to avoid data corruption.
Orientation of Displays
•ME431 IR, ME501 IR & ME551 IR support landscape and portrait orientation.
NOTE: Face-up and face-down installation is not supported by ME431 IR, ME501 IR & ME551 IR.
•When using the monitor in the portrait position, it should be rotated counter-clockwise so that the right side is
moved to the top and the left side is moved to the bottom. Improper ventilation may shorten the lifetime of the
monitor.
For further instructions on connections, please refer to standard user’s manual of the base model
monitor ME431, ME501 & ME551.
