How to Mount and Attach Options to the LCD Monitor

You can attach mounting accessories to the LCD monitor in one of the following two ways:

1.In the upright position

2.Lay the screen face down

Protective Sheet

Table		Handles		Tabletop Stand

Lay the protective sheet on a table, which was wrapped around the monitor when it was packaged, beneath the screen surface so as not to scratch the screen face.

This device cannot be used or installed without the Tabletop Stand or other mounting accessory. Failure to follow correct 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 your warranty.

Use M6 mounting screws (having a length 10 mm longer than the thickness of the mounting bracket) and tighten them securely. (Recommended torque: 470 - 635N•cm). ViewSonic recommends using mounting interface that comply with TÜV-GS and/or UL1678 standard in North America.

Caution:

For preventing the monitor from falling.

yInstall the monitor with metal brackets for wall or ceiling installation (commercially available) on your own responsibility. For detailed procedures of installation, refer to the instructions of the metal brackets.

yTo lessen the probability of injury and damage resulting from fall of the monitor in case of earthquake or other disaster, be sure to consult the bracket manufacturer for installation location.

yTo lessen the risk of falling of the monitor, thread commercially available rope (having a load capacity at least 1960N (200kgf)) through the handles at the right and left of the monitor and secure the rope to the wall mount brackets or ceiling mount brackets.

yDo not sleep where the monitor may topple over or fall in case of an earthquake or other disaster.

3. Ventilation Requirements for enclosure mounting

To allow heat to disperse, leave space between surrounding objects as shown in the diagram below.

ViewSonic CD4220

4. To avoid monitor from falling

Take measures to prevent the monitor from falling over in case of an earthquake or other disaster to lessen the probability of injury and damage resulting from fall.

As shown in the figure, secure the monitor to a solid wall or pillar using rope (commercially available) strong enough to bear the weight of the monitor. (CD4220: approx. 30 kg) When you use screw hooks (commercially available), ring screw hooks, not C-shaped screw hooks (with opening), are recommended.

Screw hook, etc.

Commercially available

Screw Holes

	Rope, etc.
	Commercially available
Clamper	Screw
		* Clamper and Screw is not supply.

Caution:

yThe effectiveness of preventing from falling substantially depends on the strength of brackets and base to which prevention device from falling is attached. When you cannot ensure sufficient strength, provide adequate reinforcement.

yThough the recommended prevention from falling is intended to lessen the probability of injury and damage, it doesn’t assure its effectiveness against any kind of earthquake or disaster.

yDo not sleep where the monitor may topple over or fall in case of an earthquake or other disaster.

yBefore moving the monitor, remove the rope that is securing the monitor. Failure to do so may result in injury or breakdown of the monitor.
