Orientation (V422/V462/V551)
• When using the monitor in the portrait position, the
monitor should be rotated clockwise so that the left side
is moved to the top and the LED 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.
Orientation (V651 only)
• DO NOT use this monitor in the portrait position.
Doing so may cause failure and void the warranty.
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 (100 mm) 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.
