Fig. 1
Two fan duct molts have been added to
alleviate the problem of abnormal noise
caused by contact between the ventilation fan
X
and the fan duct.
The ferrite core reported in T/R SP-1581 has
been eliminated.
Fig. 2
block has been added to prevent the optical
wire from becoming dislocated
Fig. 3
A cushion has been added so that the
transistor and the harness do not come in
close proximity. This measure is designed to
prevent errors caused by noise emitted by the
transistor
