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 customerÕs 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 other than those that are NEC approved, they must comply with the VESA- compatible (FDMlv1) mounting method.

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

¥NEC strongly recommends using size M6 screws (10mm + thickness of bracket in length). If using screws longer than 10mm, check the depth of the hole. (Recommended Fasten Force: 470 - 635N¥cm) NEC recommends mounting interfaces that comply with UL1678 standard in North America.

		of Bracket

Screw length should equal depth of hole (10mm) + the thickness of mounting bracket.

¥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.

¥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 display in the portrait position, the monitor should be rotated clockwise so that the left side is moved to the top and the LCD 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.

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.
