safety warnings and guidelines. Please keep this manual in a safe place for future reference.
This monitor is intended for indoor use only.
Do not expose this monitor to water or moisture of any kind. Do not place drinks or
other containers with moisture on or near the monitor. If moisture does get in or on

before reapplying power.
Do not touch the monitor, the power cord, or any other connected cables with wet
hands.

personal injury or damage to the monitor and/or other equipment.
Do not subject the monitor to extreme force, shock, or fluctuations in temperature
or humidity.
Do not block the ventilation holes in the monitor's casing. Do not place the monitor
in a confined space with inadequate ventilation. Periodically check the ventilation
holes to ensure they do not become clogged with dust, debris, or nearby items.
Do not place the monitor near a heat source, such as a fireplace, heating vent,
radiator, etc. Do not leave it in direct sunlight.
Do not place or install this monitor in an area where it can be exposed to excessive
amounts of dust, humidity, oil, smoke, or combustible vapors.
Prior to operation, check the monitor and power cord for physical damage. Do not

Unplug this monitor from the power source when not in use.
Take care to prevent damage to the power cord. Do not allow it to become

detergents. For stubborn deposits, moisten the cloth with warm water.
This monitor has no user serviceable parts. Do not open the case or otherwise
