FOR YOUR SAFETY

SAFETY PRECAUTIONS
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
  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.

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 10cm (or 4 inches) from any walls. When removing the tilt stand, the ventilation slots on the back side of the monitor can be blocked. This may overheat the monitor and may cause fire or damage. Make sure to allow enough ventilation when removing the tilt stand. 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.
