How to Mount and Att ach 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
Ta bl e Handles Ta bl e t op 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.
y Install 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.
y To 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.
y To 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.
y Do 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 13
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
Caution:
y The 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.
y Though 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.
y Do not sleep where the monitor may topple over or fall in case of an earthquake or other disaster.
y Before moving the monitor, remove the rope that is securing the monitor. Failure to do so may result in injury or
breakdown of the monitor.
