SAFETY PRECAUTIONS

ENGLISH
2 FOR YOUR SAFETY
CAUTION
INSTALLATION LOCATION

smoky areas as it may cause fire, electric shock or damage. You should also avoid areas where the
sun shines directly on the monitor.
DO NOT PLACE THE MONITOR IN A HAZARDOUS POSITION

place any heavy objects on the monitor, and that all cables are routed such that children may not
pull the cables and possibly cause injury.
MAINTAIN GOOD VENTILATION

fire. To allow adequate air circulation, place the monitor at least 10 cm (or 4 inches) from any walls.
Do not remove the tilt stand when operating the monitor. Ventilation slots on the back of the
cabinet will be blocked and the monitor may overheat if the stand is removed. This may cause fire
or damage. Operating the monitor on its back, side, upside down or on a carpet or any other soft
material may also cause damage.
DISCONNECT THE CABLES WHEN YOU MOVE THE MONITOR
When you move the monitor, turn off the power switch, unplug the monitor and be sure the signal
cable is disconnected. If you do not disconnect them, it may cause fire or electric shock.
UNPLUG THE MONITOR

itself as this may cause fire or electric shock.
DO NOT TOUCH THE PLUG WITH WET HANDS
Pulling or inserting the plug with wet hands may cause electric shock.
WHEN YOU INSTALL THE MONITOR ON YOUR COMPUTER
Be sure the computer is strong enough to hold the weight of the monitor, otherwise, you may
damage your computer.
Do not use the monitor for 24-hours continuously
The monitor is not designed to work for 24-hours continuously, do not use the monitor for 24-hours
continuously.
ERGONOMIC RECOMMENDATIONS
To eliminate eye fatigue, do not operate the monitor against a bright background or in a dark room.
For optimal viewing comfort, the monitor should be just below eye level and 40-60 cm (16-24 inches)
away from your eyes. When using the monitor over a prolonged time, a ten minute break every hour
is recommended as looking at the screen continuously can cause eye strain.
