address 3. Once you have verified that the locomotive is responding you should assign
it a unique address (we suggest the road number of the locomotive) before going any
further. This can be done either on your programming track (recommended) or on the
main if your system supports programming on the main. Be aware however that if you
do program the locomotive on the main and you have any other locomotives on your
layout assigned to address 3 (the normal default address for new locomotives) that ALL
of them will likely also be changed to your new address!
TURN ON THE SOUND
Press F8. It will start up. That was easy enough. If you press F8 when the locomotive is
already moving, it will skip the startup and the sound will just turn on. Press F8 again to
turn the sound off.
Note that if you are listening to your GMD-1 idling nicely and then you select another
engine, your GMD-1 still thinks F8 is pressed so it will keep idling along. However, if
someone else selects your GMD-1’s number and F8 isn’t pressed on his or her controller,
the GMD-1 will promptly shut down. He or she will need to press F8 again.
Ah, bless... We’re being gender neutral by saying “he or she” when 99.999% of model
railroaders are male. Suzanne we hope you appreciate that.
If you are operating with sound on a DC layout, the sounds won’t come on until the volt-
age is up around six volts or more. This is normal.
