SERVICING NOTICES ON CHECKING 1. KEEP THE NOTICES 6. AVOID AN X-RAY As for the places which need special attentions, Safety is secured against an X-ray by consider- they are indicated with the labels or seals on the ing about the cathode-ray tube and the high cabinet, chassis and parts.
ABOUT LEAD FREE SOLDER (PbF) Distinction of PbF PCB: PCBs (manufactured) using lead free solder will have a PbF printing on the PCB. (Please refer to figures.) Caution: • Pb free solder has a higher melting point than standard solder; Typically the melting point is 50°F~70°F(30°C~40°C) higher.
