If you should have any difficulties with the operation of your Tsunami Digital Sound Decoder, first check this section for hints on trouble shooting. We have found that most problems are caused by an errant CV value and are easily corrected. When all else fails, try resetting the CV values back to their defaults (see the section ‘Basic Programming’) and try again.
