factory reset. This is a myth about ESU decoders that was related to function mapping
settings using an early version of JMRI. If you manage to lose all of the sounds on your
GMD-1 then you have probably set fire to your decoder with a voltage spike. Open up
your GMD-1 and pour out the ashes.
AWESOME SLOW SPEED THINGY
There is an awesome trick that you can use to get even better slow speed running and
smoother operation. It’s called the Automatic Motor Tuning Feature. This feature will
automatically adjust the Back-EMF in most cases and give you phenomenal slow-speed
performance.
In order to use this automatic adjustment you need to use Ops mode programming, i.e.
programming on the main. Make sure your locomotive is in “forward” and that you have
lots of room in front of it on your mainline. Set CV 54 to a value of 0. Then get out of
programming mode and turn on the bell (press F1). We’ll say this again: Make sure you
have plenty of room in front of your locomotive and it is not headed for the layout edge
and the basement floor!!!
Your GMD-1 will quickly take off at full speed and gradually slow down to a stop while
the decoder reads the motor responses. You’ll have fabulous motor control after you do
this. If you ever have to reset your locomotive, you can do the automatic adjustment
again – it just takes a few seconds.
MORE INFORMATION
While addressing the features that most modelers will need for normal operation, these
instructions have covered just a small number of the many customizable features of
your ESU LokSound decoder. For advanced users who want to more fully explore the
capabilities of the decoder we suggest downloading the ESU Loksound Select decoder
manual. This is available on the GMD-1 page in the Support section of our web site.
LIMITED LIFETIME WARRANTY
We will do our best to solve any problems or issues that you may have with your GMD-1
locomotive. If your locomotive has any defects that originate from the factory, we will
repair your locomotive using new components or replace it outright should a repair not
be possible. However, we can only replace your locomotive while we have additional
ones in stock. We normally keep spares for up to six months after a model is released.

your layout and are now opening it for the first time in 2033, then you are on your own

There are a number of things that this warranty can not cover. If your GMD-1 arrives with
