Appendix 1
Safety Precautions
Observe all cautions and safety related notes located inside the display cabinet and on the display chassis.
Operation of these displays outside the cabinet or with the cover removed involves a shock hazard from the
display backlight’s inverter. Work on the display should not be attempted by anyone who is not thoroughly
familiar with precautions necessary when working on high voltage equipment.
Before returning a serviced display to the customer, a thorough safety test must be performed to verify that
the display is safe to operate without danger or shock.
Product Safety Notice
Many electrical and mechanical parts in this chassis provide special visual safety protection. 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 included 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, and hence should be prohibited.
Service Notes
When replacing parts or circuit boards, wrap the wires around terminals before soldering.
Keep wires away from high temperature components.
Keep cable and their shielding in their original position so as to reduce interference.
