rear of the monitor. If you’re unsure of the power supply in you residence, consult your local dealer
or Power Company.
Do not try to repair the monitor by yourself, as it contains no user-serviceable parts. This monitor
should only be repaired by a qualified technician.
Do not remove the monitor cabinet. There are high-voltage parts inside that may cause electric
shock to human bodies.
Stop using the monitor if the cabinet is damaged. Have it checked by a service technician.
Put your monitor only in a lean, cool, dry environment. If it gets wet, unplug the power cable

2. Product safety notice
Many electrical and mechanical parts in this chassis have special safety visual inspections and the
protection afforded by them cannot necessarily be obtained by using replacement components rated
for higher voltage, wattage, etc. Before replacing any of these components read the parts list in this
manual carefully. The use of substitute replacement parts, which do not have the same safety
characteristics as specified in the parts list, may create shock, fire, or other hazards.
3. Service notes
z
When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.
z
Keep wires away from high voltage, high temperature components and sharp edges.
z
Keep wires in their original position so as to reduce interference.
