UT1 Throttle Operation
Before you can operate a locomotive on the layout you have to know how to use the UT1 throttle. This description cannot show you all the things an experienced operator can about the UT1. Before you actually use a UT1 you should have someone show you the basics. There are quite a few buttons and lights that will be explained here.

Turning on and off track power has been described above. Setting up the throttle to operate your locomotive is the next thing you will need to do. First select your locomotive address with the Address Selector turn switches near the bottom center. Make sure the Throttle Knob is at the top or you will get the numbers backwards!

Plug in the throttle to any LocoNet outlet. The plug is just like a modular telephone plug and the tab is always facing up. To unplug the throttle just press the tab and pull out the plug. DO NOT JUST PULL ON THE WIRE!

There should be no lights lit on the throttle at this time. Turn the Throttle Knob fully counterclockwise. Press the ACQ/DISP button to acquire control of your locomotive. The Status LED (bottom middle) should light green. If it lights red then flip the Direction Toggle Switch (top left) on the throttle to the opposite direction. If the Status LED is still not green then your locomotive is acquired by another throttle and you will have to resolve this situation.

The function buttons (across the middle of the throttle) operate decoder functions in your locomotive. Usually F0 turns the headlight on or off, F1 turns the bell on or off, F2 sounds the whistle (or horn), etc. To operate F3, F4, or F5 you must hold down the Shift button (lower left) and press the appropriate button.

As you follow your locomotive around the layout you will have to move around the layout with it. Simply unplug your throttle and move on to the next LocoNet outlet and plug in. It is VERY IMPORTANT to maintain control of your locomotive by insuring that you have your throttle plugged into a LocoNet outlet unless you are moving. Don't get distracted during your move. Make sure you plug back in as soon as possible.

If you move the Throttle Knob while you are unplugged the UT1 will flash the Green LED Indicators (just below the throttle knob) in sequence to show you which way you need to turn the knob to get realigned. If the lights sequence from left to right you need to turn the throttle knob clockwise, if the lights sequence from right to left then turn the throttle knob counterclockwise.

When you are done with your run session you need to dispatch your locomotive from your control by pressing the ACQ/DISP button. The Status LED should go off.
