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.
