Safety and Maintenance Guidelines 
Important Safety Information 
  The power cord is designed for use with your monitor.  To use a different cord, use only a power source and 
    connection compatible with this monitor.
    
WARNING : 
Always connect your monitor, the computer, and  other equipment to a grounded (earthed) power 
outlet. To reduce the risk of electric shock or damage  to your equipment, do not diable the power cord grounding 
feature. The grounding plug is  an important safety feature. 
 
 
WARNING : 
For your safety, be sure that the grounded power outlet you plug the power cord into is easily   
accessible to the operator and located as close to the  equipment as possible. To disconnect power from the 
equipment, unplug the power cord from the power outlet  by grasping the plug firmly. Never pull on the cord. 
                
                
CAUTION : 
To protect your monitor, as well as your computer , connect all power cords for your computer and its 
peripheral devices (such as a monitor, pr inter, or scanner) to a surge protection device such as a power strip with 
surge protection or uninterruptible power supply (UPS). 
Not all power strips provide surge protection; the power strips  must be specifically labeled as having this ability. Use 
a power strip whose manufacturer offers a damage replacem ent policy, so you can replace your equipment if surge 
protection fails. 
                
CAUTION : A certified power supply cord has to be used  with this equipment. The relevant national 
installation and/or equipment regula tions shall be considered. A certified power supply cord not lighter 
than ordinary polyvinyl chloride flexible cord a ccording to IEC 60227 (designation H05VV-F 3G 0.75mm² 
or H05VVH2-F2 3G 0.75mm²) shall be used. Alternative a flexible cord be of synthetic rubber. 
Safety Precautions 
■ Use only a power source and connection  compatible with this monitor, as indicated on the label/back plate of 
the monitor. 
■   Be sure the total ampere rating of the products connected  to the outlet dose not exceed the current rating of the 
electrical outlet, and the total ampere  rating of the products connected to the power cord does not exceed the 
rating of the power cord. Look on the power label to de termine the ampere rating (Amps or A) for each device. 
■   Install your monitor near a power outlet that you can eas ily reach. Disconnect the monitor by grasping the plug 
firmly and pulling it from the outlet. Never disconnect the monitor by pulling the cord. 
■   Do not allow anything to rest on the power cord. Do not walk on the cord. 
Maintenance Guidelines 
            
To enhance the performance and extend the life of your monitor: 
                 ■    Do not open your monitor cabinet or attempt to service  this product yourself. If your monitor is not operating 
properly or has been dropped or damaged, contact your Lenovo authorized de aler, reseller, or service 
provider. 
                 ■    Adjust only those controls that are de scribed in the operating instructions. 
                 
■    Turn your monitor off when not in use. You can substantia lly increase the life expectancy of the monitor by using 
a screen saver program and turning  off the monitor when not in use. 
                 ■    Keep your monitor in a well-ventilated area, aw ay from excessive light, heat, or moisture. 
                 ■    Slots and openings in the cabinet are provided for ventilation. These openings must not be blocked or covered. 
Never push objects of any kind into  cabinet slots or other openings. 
                 ■    Unplug the monitor from the power outlet before clea ning. Do not use liquid cleaners or aerosol cleaners. 
                 ■    Do not drop the monitor or place it on an unstable surface. 
                 ■    When removing the monitor base, you must lay the monitor  face down on a soft area to prevent it from getting 
scratched, defaced, or broken. 
           Cleaning the Monitor 
            The monitor is a high-quality optical device that requires  special care when cleaning. To clean the monitor, follow 
                      these steps:

2.   Unplug your monitor from the power outlet before cleaning.  
                                  CAUTION: Do not use benzene, thinner, ammonia, or any volatile substance to clean the monitor screen or cabinet.
