Boards requiring use of lead-free solder are printed with a
lead free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come
printed with the lead free mark due to their particular size.)
: LEAD FREE MARK
m
.Be sure to use the lead-free solder for the printed circuit
board printed with the lead free mark.
.The lead-free solder melts at a temperature about 40 dC
higher than the ordinary solder, therefore, it is recom-
mended to use the soldering iron having a temperature
regulator.
.The ordinary soldering iron can be used but the iron tip
has to be applied to the solder joint for a slightly longer
time. The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful.

Reserved stand tool (reference)
2-1-1. Camera Block Assembly
Precaution for replacement
After replacing the camera block assembly, do not turn on
the power before attaching the cover of the camera block
assembly. The light shielding processing is not applied to
the side of the prism block of the camera block assembly.
Because of this, if you turn on the power without attaching
the cover of the camera block assembly after it is replaced,
the light enters the side of the prism portion, which causes
the overexposure (whiteout condition) of the output image.
When the power is turned on, the subsequent defect of the
imager is checked. If the power is turned on in the above
state (light entering the side of the prism without cover), it
may cause an erroneous judgment. If it is required to turn
on the power for checking the assembly (wiring) and so on
after replacing the camera block assembly, perform the
following before turning on the power.
.Attach the cover to the camera block.
.Cover with the light shield without applying force on the
fixing portion of the imager.
