Replaces the UT4 throttle.


This throttle can operate wirelessly using infrared light in simplex mode. For infrared communication (UT6D/UT6DE), a compatible infrared receiver such as the UR90, UR91, or UR92 attached to the LocoNet throttle network is required. If using radio communication (UT6D/UT6DE), UR92 or UR93 is required. When operating wireless, the cord can be detached.

When operating in wireless mode outdoors, radio communications are required as infrared is unreliable and/or unusable when outdoors.

Among the many improvements over the UT4 throttle is how it's powered when operating wirelessly. Previous generates used a 9V battery nonrechargeable battery, and the throttle had no power switch. This version is powered by 3x AA batteries, or using Digitrax BP600MH battery pack that is rechargeable. There is a power on/off switch, so no more flipping batteries around to save battery life in previous generations.

The addition of the display screen supports additional features and better confirmation of status.

For duplex radio operations, see UT6D or UR6DE for Europe. The use of radio is required for wireless outdoor operations because infrared will not work outdoors in the daytime.
