The right throttle knob on my Digitrax DT 400 throttle no longer responds properly. It's most noticible when turning the knob counterclockwise and instead of a straight-line sequence the readout might run
30-29-28-27-26-25-24-36-34-33-32-44-40-39-27-36-35 and so forth. It also happens when increasing speed but not so noticibly.Is this something that I can reprogram or do I need to send my throttle to Digitrax for service?
