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 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.

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.
