I.SAFETY PRECAUTIONS
This monitor is manufactured and tested on a ground principle that a user's safety comes first. However, improper
use or installation may cause damage to the monitor as well as to the user. Carefully go over the following
WARNINGS before installing and keep this guide handy.
WARNINGS:
1. This monitor should be operated only at the correct power sources indicated on the label on the rear end of the
monitor. If you're unsure of the power supply in your residence, consult your local dealer or power company.
2. Use only the special power adapter that comes with this monitor for power input.
3. Do not try to repair the monitor yourself, as it contains no user-serviceable parts. Only a qualified technician
should repair this monitor.
4.Do not remove the monitor cabinet. There are high-voltage parts inside that may cause electric shock to human
bodies, even when the power cord is unplugged.
5.Stop using the monitor if the cabinet is damaged. Have it checked by a service technician.
6 Put your monitor only in a clean, dry environment. If it gets wet, unplug the power cable immediately and consult
your service technician.
7. Always unplug the monitor before cleaning it. Clean the cabinet with a clean, dry cloth. Apply non-ammonia
based cleaner onto the cloth, not directly onto the glass screen.
8.Do not place heavy objects on the monitor or power cord.
II. 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 voltages,
wattage, etc. Before replacing any of these components read the parts list in this manual carefully. The use of
substitute replacement parts that do not have the same safety characteristics as specified in the parts list may
create shock, fire, or other hazards.
III.SERVICE NOTES
1. When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.
2. When replacing a high wattage resistor (more than 1W of metal oxide film resistor) in circuit board, keep the
resistor about 5mm away from circuit board.
3. Keep wires away from high voltage, high temperature components and sharp edges.
4. Keep wires in their original position so as to reduce interference.
5. Usage of this product please refers to also user's manual.
