• Prior to mounting, inspect the installation
location to ensure that it is strong enough to support the weight of the unit
so that the unit will be safe from harm.
• For detailed information, refer to the instructions included with the
mounting equipment.
• Make sure that there is no gap between the monitor and the bracket.

of the monitors may happen due to temperature changes. Due to this it is
recommended that over one millimeter gap is kept between adjacent
monitor edges.
• When installing, do not apply pressure to the screen or excessive force to
any part of the monitor by pushing or leaning on it. This may cause the
monitor to become distorted or damaged.

Mounting location
CAUTION
• The ceiling or 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 the monitor next to a location where the main power
supply is fed into the building.
• DO NOT install the monitor in a location where people can easily grab and
hang onto the unit or the mounting equipment.
NOTE: Allow for adequate ventilation or provide air conditioning around the
monitor, so that heat can properly dissipate away from the monitor
and from the mounting equipment.
Mounting on ceilings
• Ensure that the ceiling is sturdy enough to support the weight of the unit
and the mounting equipment 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

Orientation
• When using the monitor in the portrait position, it should be rotated
clockwise so that the right side is moved to the top, left side is moved to
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.

• Do not mix battery brands.
• Do not combine new and old batteries.This can shorten battery life or
cause liquid leakage of batteries.
• Remove dead batteries immediately to prevent battery acid from leaking
into the battery compartment.
• Do not touch exposed battery acid, it may injure your skin.
NOTE: If you do not intend to use the Remote Control for a long period of
time, remove the batteries.
