1. PRECAUTION AND NOTICES
1.1. 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:
! 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.

! 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.
! Keep the monitor away from magnetic objects, motors, TV sets, and transformer.
! Do not place heavy objects on the monitor or power cord.
1.2. 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 voltages, 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.
1.3. 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 refer to also user's manual.
