SAFETY PRECAUTIONS
WARNING
STOP OPERATING THE MONITOR WHEN YOU SENSE TROUBLE
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 fi re or electric shock.
NEVER REMOVE THE CABINET
High voltage circuits are inside the monitor. Removing the cabinet may expose you to the danger of
fi re 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 fi re, 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 fi re or electric
shock.
OPERATE UNDER THE SPECIFIED POWER SUPPLY
Be sure to operate the monitor only with the specifi ed power supply. Use of an incorrect voltage will
cause malfunction and may cause fi re or electric shock.
ENGLISH
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 fi re or electric shock.
ADVERSE WEATHER CONDITIONS
It is advisable not to operate the monitor during a heavy thunder storm as the continual breaks in
power may cause malfunction. It is also advised not to touch the plug in these circumstances as it
may cause electric shock.
FOR YOUR SAFETY 1
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
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
ENGLISH
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
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 fi re 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.
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.
2 FOR YOUR SAFETY
SPECIAL NOTES ON LCD MONITORS
The following symptoms are normal with LCD monitors and do not indicate a problem.
NOTE
This LCD cannot be used outdoors.
This LCD cannot be used with the screen facing upwards.
If you use a cable longer than the supplied one, the picture quality is not guaranteed.
- When you fi rst turn on the LCD monitor, the picture may not fi t in the display area
because of the type of computer that is used. In this case, adjust the picture position to
the correct position.
- You may fi nd slightly uneven brightness on the screen depending on the desktop
pattern you use.
- Due to the nature of the LCD screen, an afterimage of the previous screen may remain
after switching the image, when the same image is displayed for hours. In this case, the
screen is recovered slowly by changing the image or turning off the Power Switch for
hours.
ENGLISH
FOR YOUR SAFETY 3
USAGE CONFIRMATION
This product is designed for optimum usage at 24hours per day.
The display is compatible for usage in Landscape/Portrait applications.
IMAGE PERSISTENCE / IMAGE STICKING
Please be aware that all LCD screens can experience Image Persistence or Image Sticking. This
occurs when a residual image remains visible on a screen when static images are displayed for long
periods of time. LCD Image Persistence is not permanent but constant images being displayed for a
long period of time should be avoided.
To counteract Image Persistence, turn off the monitor for as long as the previous image was
displayed, so if an image was on the monitor for 1 hour and there is evidence of a residual or “ghost”
image, you should turn off the monitor for 1 hour in order to clear the residual image.
For all LFD products, iiyama recommends displaying moving images and utilising a moving screen
ENGLISH
saver at regular intervals whenever the screen is idle. You could also turn off the monitor when not
in use to assist the prevention.
Other ways to reduce the risk of Image Persistence will be to utilise the FAN-on function (if
available), Low Backlight and Low Brightness settings.
FOR EXTENDED USE AS A PUBLIC DISPLAY
Image Sticking on LCD Panel
When a static image is displayed for hours, an electric charge trace remains near the electrode
inside the LCD producing a “ghost” image. (Image Persistence).
Image Persistence is not a permanent feature.
Recommendations
To prevent Image Sticking and promote longer life expectancy of display, we recommend the
following:
1. Avoid static images displayed for long periods – change static images on continuous loop.
2. Turn off monitor when not in use, either by remote control or use Power Management or Schedule
functions.
3. When monitor is installed in high ambient temperature environment(s) or in an enclosed position,
utilise the Cooling Fan, Screen Saver and Low Brightness functions.
4. Suitable ventilation for any monitor is an expectation of any installation – climate control systems
may need to be employed.
5. We strongly recommend utilisation of active cooling with fans for long operation times or high
ambient temperature environments.
