FOR YOUR SAFETY
WARNING
STOP OPERATING THE MONITOR IF YOU ARE AWARE OF ANY PROBLEMS
If you notice any abnormal phenomena such as smoke, strange sounds or fumes, unplug the
monitor and contact your dealer or iiyama service center immediately. Further use may be
dangerous and can cause fire or electric shock.
NEVER REMOVE THE CABINET
High voltage circuits are inside the monitor. Removing the cabinet may expose you to the danger of
fire or electric shock.
DO NOT PUT ANY OBJECT INTO THE MONITOR
Do not put any solid objects or liquids such as water into the monitor. In case of an accident, unplug
your monitor immediately and contact your dealer or iiyama service center. Using the monitor with
any object inside may cause fire, electric shock or damage.
INSTALL THE MONITOR ON A FLAT, STABLE SURFACE
The monitor may cause an injury if it falls or is dropped.
DO NOT USE THE MONITOR NEAR WATER
Do not use where water may be splashed or spilt onto the monitor as it may cause fire or electric
shock.
OPERATE UNDER THE SPECIFIED POWER SUPPLY
Be sure to operate the monitor only with the specified power supply. Use of an incorrect voltage will
cause malfunction and may cause fire or electric shock.
PROTECT THE CABLES
Do not pull or bend the power cable and signal cable. Do not place the monitor or any other heavy
objects on the cables. If damaged, the cables may cause fire or electric shock.
ADVERSE WEATHER CONDITIONS

may cause electric shock.
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 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
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
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
If the monitor is not in use for a long period of time it is recommended that it is left unplugged to
avoid accidents.
HOLD THE PLUG WHEN DISCONNECTING
To disconnect the power cable or signal cable, always pull it by the plug. Never pull on the cable
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.
REMARK FOR 24/7 USAGE
This product is not specifically designed for 24/7 usage in all environments.
OTHERS
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.

ENGLISH
FOR YOUR SAFETY 3
