Depth Reading error (i70 & a95 MFD)

[RickSegal]

Greetings,

I have:

a95 MFD
i70 Display
P70 A/P
iTC-5 Converter
DST-800 Triducer

With respect to depth, I'm having a sporadic problem. I updated the firmware on the various units including the V17 Lighthouse software. I got some error message which caused me to reset the MFD. I got everything re-configured but now I'm getting a bad reading on depth. Unlike the i50 problem discussed earlier, I'm getting 2.2 when it should be 12.2 as verified by the boats next to me. The unit is clear/clean. I her out (fixing the magnetic issue with the AP) but depth in 120ft showed 12, jumping to 2.2, back to 12.

Is there a software configuration or test, etc. that I can do given I reset the systems so I may have done something. Are there any other suggestions to determine if the triducer is bad?

Thanks,
