WHEN REPLACING DVD DECK [ When removing the DVD Deck ] Before removing Pick Up PCB and DVD PCB connector, short circuit the position shown in Fig. 1 using a soldering iron. If you remove the DVD Deck with no soldering, the Laser may be damaged. [ When installing the DVD Deck ] Remove all the soldering on the short circuit position after the connection of Pick Up PCB and DVD PCB connector.
TAPE REMOVAL METHOD AT NO POWER SUPPLY Remove the TV/DVD/VCR block from the main unit as shown in Fig. 1 below can be seen. (Refer to item 1 of the DISASSEMBLY INSTRUCTIONS.) Remove the screw 1 of the Deck Chassis and remove the Loading Motor. Rotate the Pinch Roller Cam in the direction of the arrow by hand to slacken the Video Tape.
PARENTAL CONTROL - RATING LEVEL 4 DIGIT PASSWORD CANCELLATION If the stored 4 digit password in the Rating Level menu needs to be cancelled, please follow the steps below. Turn Unit ON. Set the DVD to the Stop Mode. Check that 'No disc' is displayed on the screen. Press and hold the 'STOP(DVD)' button on the front panel.
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.
