Notes on Disconnecting Between the OP Section (DVBU101) and the DMB19 Board
Note: When disconnecting between the OP section (DVBU101) and the DMB19 board, be sure to make a solder bridge for electrostatic prevention as il-
lustrated 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.
