DMB19 board, be sure to make a solder brige for electrostatic pre-
vention as illustrated 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 con-
nected.

 

  Be sure to remove the solder bridge after the OP section and the 

DMB19 board have been connected.
