How to remove a loco from an NCE system

There is no need, or way to “remove” a loco from the system. However, if having the loco number on the display is an issue, simply bring up the loco number in question using the recall button.  Press select loco, then press all zeros , then press enter. That will remove it from the display. Or you can do the same process and overwrite the old number with a new loco number.
