I have known instantly it happened, several times now, that I had forgotten to ensure that my Digitrax DT 400 was in Ops Mode, and not Paged Mode when programming a certain locomotive. When you press "Enter" to upload the change(s), the Digitrax system that I have shuts down power to the track immediatelyin Paged Mode...so the deafening silence following the beep acknowledging the change leaves me stunned...and feeling the same...if you catch my meaning.
We all make these errors now and then. Thanks for coming clean.
