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.
z Adjustment of this product please refers to the user’ manual.
