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
 When replacing parts or circuit boards, clamp the lead wires around terminals before
soldering.
 Keep wires away from high voltage, high temperature components and sharp edges.
 Keep wires in their original position so as to reduce interference.
 Adjustment of this product please refers to the user’ manual.
