QUICK START - BASIC OPERATION
The MTH GG-1 contains state-of-the art electronics with several built-in
automatic features for incredibly realistic operation. Despite these advanced
features, the GG-1 is easy to operate with any compatible standard AC
transformer (see the compatibility chart on page 33). The GG-1
locomotive is controlled by a ProtoSound® DCRU® electronic reverse unit.
The reverse unit operates in the same manner that all reverse units function
by using forward, neutral and reverse states that are entered each time the
throttle is turned on and off or by using the transformer direction switch (if
so equipped).
The reverse unit is designed to ignore dirty track, dead spots on switches
or minor short circuits without disrupting the engine operation, even at
slow, prototypical speeds. Once the engine is placed on the track, the
throttle on the transformer can be advanced. You will see that only the
engine’s lights come on and that only two dings of the ProtoSound bell
occur followed by the diesel start-up sounds (on ProtoSound equipped 3-rail
models). The engine does not run. This is known as the RESET state and
is explained in more detail beginning on Page 4. The ProtoSound®
DCRU® will not power the motors until the throttle is turned OFF and then
ON again. At this point, the engine will now function just like any other
electronic or mechanical E-unit.
