SAFETY PRECAUTIONS
ENGLISH
2 FOR YOUR SAFETY
CAUTION
INSTALLATION LOCATION
Do not install the monitor where sudden temperature changes may occur, or in humid, dusty or
smoky areas as it may cause fi re, electric shock or damage. You should also avoid areas where the

DO NOT PLACE THE MONITOR IN A HAZARDOUS POSITION
The monitor may topple and cause injury if not suitably located. Please also ensure that you do not
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
Ventilation slots are provided to keep the monitor from overheating. Covering the slots may cause
fi re. 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 fi re
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 fi re or electric shock.
UNPLUG THE MONITOR
