To control the speed of a locomotive with your DT300:
1. Activate the loco address on either throttle by either pressing the C/R key or the R THROTTLE knob to gain control of the loco on the right side of the display and the L/t key or the L THROTTLE knob to gain control of the loco on the left.
2. Turn the THROTTLE knob clockwise to increase speed and counterclockwise to decrease speed or
3. Use the Y/+ and N/- keys to increase and decrease speed. The percentage of full speed will be displayed in the text line of the display above the loco address. The percentage of full speed will also be displayed on the Bar Graph above the Text Area in the display.
If a loco address is part of a consist and is not the “TOP” (or controlling locomotive) and you try to change its speed the LCD screen will show “cn” or “mid” in the text area where % speed would normally appear. The “cn” and “mid” lets you know that the loco you have selected is part of a consist and that you cannot change the speed or direction of this loco independently of the consist.
