1. Change the rotary address selectors to a different address. The Status light

will change to blinking red showing that the loco address is 

released.

2. (Optional Dispatch Step) Press the Dispatch key if you wish to Dispatch

this loco address and make it available for selection by another throttle as a

Dispatched loco address.

rotary address selectors to a different address.  The Status light will change

to blinking red to show the loco address is 

released

.

2. (Optional Dispatch Step)  Press 

and hold

the Dispatch key.

Dispatch this loco.

Stealing:  

Stealing is defined as acquiring control of a loco address that is

being used currently by someone else on another throttle.  To ensure the loco-
motive does not get conflicting speed and direction commands, it is best to
ensure the other throttle has released this address.

To ‘Steal’ a loco address:

(not plugged in and joined to a UR92 Group)

1. Change the address selectors to desired address
2. Press the Steal key . The Status light will start blinking green to show the

loco is now selected after being stolen from another throttle.

IR mode (no UR92) or Wired Mode :

1. Release the loco address and unplug the UT4D from LocoNet.
2. Dial up the address of the loco you want to steal.
3. Press 

and hold

the ‘STEAL’ key while plugging the throttle into a LocoNet

jack.  Note: To steal or dispatch another loco, you must unplug the UT4D

and repeat the above sequence.
