5-2. THE BCD OUTPUT IS STABLE

The indicating value and analog monitor output are stable, and the BCD output is also stable.
The input cable is not connected to the [INPUT] connector correctly or is breaking.
Check the channels.
The indicating value and analog monitor output are not stable, but the BCD output is stable.
The BCD output cable is not connected to the connector correctly or is breaking.
Repair the BCD output cable or replace the cable with a new one.

5-3. THE D/A OUTPUT IS STABLE

The indicating value and analog monitor output are stable, and the D/A output is also stable.
The input cable is not connected to the [INPUT] connector correctly or is breaking.
