• Verify that the resistance of transducers is within Specification (1-2 Ω).
• Check the Acquisition board.

chord is not indicating
• Check the resistance of the failed transducer.
• If Chord A is not indicating, change the transducer cables from Chord D to chord A.
If Chord D then fails, the transducers are bad on Chord A.

chord fails in either chord.
Note that the outside chord cables cannot be exchanged with inner
chord cables.
