Safety Precautions
Read through the following Safety Precautions before using the monitor.
• Only use the accessories that are provided with the monitor or that
which are recommended by the manufacturer.
• Keep the plastic packaging bag for the product in a place that
cannot be reached by children.
• Before connecting the monitor to the power outlet, make sure that
the voltage rating of the power cable is compatible with the power
specication in the country where you are located.
• The power cord plug must be connected to a properly wired and
grounded power outlet.
• Do not touch the plug with wet hands, otherwise easily cause
electric shock.
• Place the monitor in a stable and well-ventilated place.
• Do not place the monitor near any heat sources such as electric
radiators or direct sunlight.
• The holes or openings on the monitor are for ventilation. Do not
cover or block the ventilation holes with any objects.
• Do not use the monitor near water, drinks, or all types of liquids.
Failure to do so may result in electric shock or damage to the
monitor.
• Make sure to unplug the monitor from the power outlet before
cleaning.
• As the screen surface is easy to be scratched, avoid touching the
surface with any hard or sharp object.
• Use a soft lint-free cloth instead of a tissue to wipe the screen. You
may use a glass cleaner to clean the monitor if required. However,
never spray the cleaner directly onto the screen.
• Disconnect the power cable if the monitor is not being used for a
long period of time.
• Do not attempt to disassemble or repair the monitor yourself.
