LEAD-FREE SOLDER The PWB's of this model employs lead-free solder. The "LF" marks indicated on the PWB's and the Service Manual mean "Lead-Free" solder. The alphabet following the LF mark shows the kind of lead-free solder.

Never use conventional lead solder thread, which may cause a breakdown or an accident. Since the melting-point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the exclusive-use soldering iron is recommended. © (2) NOTE FOR SOLDERING WORK Since the melting-point of lead-freeCsoOldPerYisRabIGouHt 2T20°C, wXhXicXh Xis aBboYuSt 4H0°ACRhiPgheCr OthaRnPthOatRofAcoTnIvOenNtional lead solder, and its soldering capacity is separation inferior or may teoxcceoendvetnhteiohneaalto-rnees,isittiivseatpetmtopekreaeAtpuLrtehLeofRscoIolGdmepHrionTngeSinrotsnR. iUEnscSeoEnetnaRocuVt gwEhithcDat.rheetPoWseBpaforar tloenthgeerstoimldee.riTnhgisiromnafyrocmautshee land PWB when completion of soldering is confirmed.
