F-3 A B A DIESEL ENGINE SET
This engine is equipped with a coil-wound Proto-Coupler for remote uncoupling action.
Because the Proto-Coupler is controlled through the Proto-Sound 2.0 microprocessor,
it does not require an uncoupling track section or modification to your layout to func-
tion. Use the codes listed below.
Rear Coupler:
To fire the rear coupler, press the Bell button once followed immedi-
ately
by three pushes of the Horn/Whistle button. The sound of the lift bar and air line
depletion will play, and the knuckle will be released.
PROTO-COUPLER ®OPERATION
M.T.H. engines equipped with Proto-Sound 2.0 have speed control capabilities that
allow the engine to maintain a constant speed up and down grades and around
curves, much like an automobile cruise control. You can add or drop cars on the run,
and the engine will maintain the speed you set.
While the engine is programmed to start with the speed control feature activated, you
can opt to turn it off
.
This means the engine s speed will fall as it labors up a hill and
increase as it travels downward. It is also affected by the addition or release of cars
while on the run. To maintain a constant speed when speed control is turned off, you
need to adjust the track voltage yourself. When speed control is off, the volume will
drop to allow for better low voltage operation. Full volume is restored upon reactivation
of speed control.
To turn speed control on and off:
First, put the engine in neutral, then press the
transformer s Horn/Whistle button one time then immediately press the Bell button two
times. Two whistle blasts will indicate that the engine has made the change. Repeat
the
1 Horn/Whistle, 2 bells code to return it to the other state. You will want to do this
during the initial neutral start-up if you ever couple this engine with another
SPEED CONTROL
You can lock your engine into a directional state (forward, neutral, reverse) to prevent
it from changing directions. To do this, put the engine into the direction you want or in
neutral, run it at a very low speed (<10 scale mph), and quickly but firmly press your
remote s Horn/Whistle button once followed immediately by three presses of the Bell
LOCK INTO A DIRECTIONAL STATE
