for Acers global product offering. To better fit  local market requirements and enhance product comp etitiveness, 
your regional office may have decided to extend the  functionality of a machine (e.g. add-on card, modem, or extra 
memory capability). These LOCALIZED FEATURES will N OT be covered in this generic service guide. In such 
cases, please contact your regional offices or the  responsible personnel/channel to provide you with f urther 
technical details. 
  
2. Please note W HEN ORDERING FRU PARTS, that you sh ould check the most up-to-date information available on 
your regional web or channel. If, for whatever reas on, a part number change is made, it will not be no ted in the 
printed Service Guide. For ACER-AUTHORIZED SERVICE  PROVIDERS, your Acer office may have a 
DIFFERENT part number code to those given in the FR U list of this printed Service Guide. You MUST use the list 
provided by your regional Acer office to order FRU  parts for repair and service of customer machines. 
 
Warning: (For FCC Certified Models)  
Note: This equipment has been tested and found to comply  with the limits for a Class B digital device, pursuant to

Warning:  
To prevent fire or shock hazard, do not expose the  monitor to rain or moisture. Dangerous high voltage s are present 
inside the monitor. Do not open the cabinet. Refer  servicing to qualified personnel only.

Precautions 
 
 Do not use the monitor near water, e.g. near a bat
htub, washbowl, kitchen sink, laundry tub, swimming  pool or in 
a wet basement. 
   Do  not  place  the  monitor  on  an  unstable  trolley,  s tand,  or  table.  If  the  monitor  falls,  it  can  injure  a  person  and 
cause  serious  damage  to  the  appliance.  Use  only  a  t rolley  or  stand  recommended  by  the  manufacturer  or  sold 
with the monitor. If you mount the monitor on a wal l or shelf, uses a mounting kit approved by the man ufacturer 
and follow the kit instructions. 
   Slots  and  openings  in  the  back  and  bottom  of  the  c abinet  are  provided  for  ventilation.  To  ensure  reliable 
operation of the monitor and to protect it from ove rheating, be sure these openings are not blocked or  covered. 
Do not place the monitor on a bed, sofa, rug, or si milar surface. Do not place the monitor near or ove r a radiator 
or heat register. Do not place the monitor in a boo kcase or cabinet unless proper ventilation is provided. 
   The monitor should be operated only from the type  of power source indicated on the label. If you are not sure of 
the type of power supplied to your home, consult yo ur dealer or local power company. 
   The monitor is equipped with a three-pronged groun ded plug, a plug with a third (grounding) pin. This plug will fit 
only into a grounded power outlet as a safety featu re. If your outlet does not accommodate the three-w ire plug, 
have an electrician install the correct outlet, or  use an adapter to ground the appliance safely. Do n ot defeat the 
safety purpose of the grounded plug. 
     Unplug the unit during a lightning storm or when  it will not be used for long periods of time. This will protect the 
monitor from damage due to power surges. 
   Do not overload power strips and extension cords.  Overloading can result in fire or electric shock. 
   Never  push  any  object  into  the  slot  on  the  monitor   cabinet.  It  could  short  circuit  parts  causing  a  fire  or  electric 
shock. Never spill liquids on the monitor. 
   Do  not  attempt  to  service  the  monitor  yourself;  op ening  or  removing  covers  can  expose  you  to  dangerou s 
voltages and other hazards. Please refer all servic ing to qualified service personnel 
   To  ensure  satisfactory  operation,  use  the  monitor  only  with  UL  listed  computers  which  have  appropriat e 
configured receptacles marked between 100 - 240V AC , Min. 5A. 
   The wall socket shall be installed near the equipm ent and shall be easily accessible. 
  
Special Notes On LCD Monitors 
 
The following symptoms are normal with LCD monitor  and do not indicate a problem. 
 
Notes 
 
  Due to the nature of the fluorescent light, the sc reen may flicker during initial use. Turn off the Power Switch and 
then turn it on again to make sure the flicker disa ppears. 
   You may find slightly uneven brightness on the scr een depending on the desktop pattern you use. 
   The  LCD  screen  has  effective  pixels  of  99.99%  or  m ore.  It  may  include  blemishes  of  0.01%  or  less  such  as  a 
missing pixel or a pixel lit all of the time. 
   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.
