How to Mount and Attach Options to the LCD Monitor 
 
You can attach mounting accessories to the LC D monitor in one of the following two ways: 
1. In the upright position 
 
2. Lay the screen face down 
 
 
Lay the protective sheet on a table, which was wr apped 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 re commends 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 in stallation (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 dam age resulting from fall of the monitor in case of earthquake or other disaster, 
be sure to consult the bracket manuf acturer for installation location. 
y   To lessen the risk of falling of the monitor, thread commerc ially available rope (having a load capacity at least 1960N 
(200kgf)) through the handles at the right and left of the m onitor 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.

4. To avoid monitor from falling 
Take measures to prevent the monitor fr
om 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. (C D4620: approx. 34.6 kg) When you use screw  hooks (commercially available), ring 
screw hooks, not C-shaped screw hooks (with opening), are recommended. 
 
 
Caution: 
y   The effectiveness of preventing from falling substantiall y depends on the strength of brackets and base to which 
prevention device from falling is attached. When y ou 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 securi ng the monitor. Failure to do so may result in injury or 
breakdown of the monitor.
