Distinction of PbF P.C.B.P.C.B.s (manufactured) using lead-free solder will have a PbFstamp on the P.C.B.This model uses lead free solder (PbF). For repair use onlylead free handsolder.Caution:Pb free solder has a higher melting point than standardsolder; Typically the melting point is 50 - 70 F (30 - 40 C)higher. Please use a high temperature soldering iron. Incase of the soldering iron with temperature control, pleaseset it to 700 +/-20 F (370 +/-10 C). Pb free solder will tendto splash when heated too high (about 1100 F/ 600 C).When soldering or unsoldering, please completely removeall of the solder on the pins or solder area and be sure toheat the soldering points with the Pb free solder until itmelts enough.4 PRECAUTION OF LASER DIODECAUTION: ACHTUNG:This product utilizes a laser diode with the unit turned “on”,invisible laser radiation is emitted from the pickup lens.Wave length: 662 nm/795 nmMaximum output radiation power from pickup: 100μ W/VDE.Laser radiation from the pickup lens is safety level, but be surethe followings:Dieses Produkt enthält eine Laserdiode.Im eingeschalteten Zustand wird unsichtbare Laserstrahlung von derLasereinheit ausgestrahlt.Wellenlänge: 662 nm/795 nmMaximale Strahlungsleistung der Lasereinheit: 100μ W/VDE.Die Strahlung der eingeschalteten Lasereinheit ist ungefährlich, wennfolgende Punkte beachtet werden:1. Do not disassemble the optical pickup unit, since radiationfrom exposed laser diode is dangerous.1. Die Lasereinheit nicht zerlegen, da die Strahlung an der freigelegtenLaserdiode gefährlich ist.2. Do not adjust the variable resistor on the pickup unit.It was already adjusted.2. Den werksseitig justierten Einstellregler der Lasereinheit nichtverstellen.3. Do not look at the focus lens using optical instruments. 3. Nicht in die Fokussierlinse blicken.4. Recommend not to look at pickup lens for a long time. 4. Auch nicht mit optischen Instrumenten in die Fokussierlinse blicken.5 HANDLE THE LEAD-FREE SOLDER5.1. ABOUT LEAD FREE SOLDER (PbF)7DMR-ES30VEG / DMR-ES30VEC / DMR-ES30VEB
