KB367: DT400 - Erratic Behavior

This article was last updated on Jan. 20, 2012, 12:33 p.m. | Print Article | Leave Feedback

I have a DCS100.

I do not understand why my DT400's speed increases (all the way up to 99) sometimes when I plug it in.

Also, sometimes the Loco number (when selected when this is taking place) will increase too.

There is no control enabled when this is taking place.

If I plug in a DT100 it operates normally.


One of the buttons on the DT400 may be stuck, leading to this behavior.

Take a look at the control panel of the DT400 and you will probably see this stuck button since it will not be in a fully returned position.

You may find it helpful to take a modeler's knife and gently cut the front graphic foil slightly away from the button.
