2-1-1. Installing Jumper Board

The DA-128 board is provided with a jumper board CN-1566 on it. The CN-1566 board is necessary
when the RC-68 board of OHB-730WS/730WSP/750WSA/750WSAP is not installed. Unless the RC-68
board is installed, be sure to connect the CN-1566 board to the DA-128 board. If not, the video image
will not be displayed normally.

Excessive current in the internal circuitry will trip the internal circuit breaker regardless of causes. If the
circuit breaker trips once, check the circuit or block concerned, and then press the appropriate breaker
release button. If there is no trouble, the power to the unit will be turned on.
