1-4. Lead-free Solder
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.
1-3. Replacing the Electrolytic Capacitor
The electrolytic capacitor used in this unit needs to be
replaced periodically.
When a service for repair or maintenance is provided, and
if the unit has been used for a long period of time, it is
recommended that the following electrolytic capacitor (or
assembled part that include it) to be replaced at once after
having consent from the customer. Refer to Section A-3
for the part number of replacing part.
The length of the operating life varies depending on the
environment and conditions of how the part has been used.
Make note that the part is not guaranteed for the number of
years described below. It is served as a guide for replace-
ment.
