Note: When disconnecting between the OP section (DVBU101) and the DMB19 board, be sure to make a solder brige for electrostatic prevention as illus-

trated in the fi gure (before disconnection).

 

  On the contrary, when installing the OP section, never remove the solder bride until the OP section and the DMB19 board are connected.

 

  Be sure to remove the solder bridge after the OP section and the DMB19 board have been connected.

Manual Opening and Closing the DVD Tray
