Set Up Checklist
- Lubricate the locomotive
- Check to see whether the battery needs to be charged for full sound effects
- Apply power to run as described in the Basic Operating Section of this manual
Lubrication
You should lubricate the engine to prevent it from squeaking. Use
light household oil and follow the lubrication points marked “L”
(shown below). Do not over-oil. Use only a drop or two on each
pivot point.
Checking the Battery
You may find, if your locomotive was built several months before you set it up,
that the rechargeable battery has run down and needs to be charged before
operating. If you notice that the sounds are garbled, test and charge the engine as
described in the "Self-Charging Battery Back-Up" on page 17.

Basic Operation
The Throttle knob controls how fast your train will travel. Turn the throttle knob
up ½-way, until the engine lights shine bright. Put the engine into motion by
pressing the Direction button on your transformer once. (hold it for approximately
1 second)
If the engine does not begin to move as soon as you firmly press the Direction
button, you may not have sent enough voltage to the track to make the train move.
Turn the throttle up a bit higher until the train begins to move.
Activating Features
Throttle - To increase or decrease track voltage, and therefore train speed, turn the
throttle control knob. Turning clockwise will increase voltage and speed, while
turning counterclockwise will decrease voltage and speed. The engine will maintain
the speed you set after you release the throttle until you turn it again to change the
voltage and speed.
Bell - To sound the bell, in an engine equipped with a bell firmly press and release
the Bell button. To turn the bell off, press and release the Bell button again. The
bell will continue to ring from the time you turn it on until you press and release
the button again to turn it off.
Horn/Whistle - To sound the Horn/whistle, firmly press the Horn/Whistle
button. The horn or whistle will sound for as long as you continue to depress the
button. It will stop when you release the button.
Direction - Your train is programmed to start in neutral. The train will always
cycle neutral-forward-neutral-reverse with each press and release of the direction
button. The engine is programmed to restart in neutral each time the track voltage
is turned off for 25 seconds or more.

Proto-Sound® 2.0 Operating Instructions
This manual contains the operating instructions for Proto-Sound® 2.0 in
conventional mode only. Instructions for accessing DCS command mode features
accompany the DCS Remote Control System equipment.
Activating Proto-Sound® 2.0 Conventional Mode
Features
Because Proto-Sound® 2.0 is an all-new system developed by M.T.H.'s own
research and development team, it operates differently from original Proto-Sound.
Most Proto-Sound® 2.0 features are automatically enabled, and Reset has been
eliminated, so there is no need to program features as with original Proto-Sound.
Although the new system is easier to operate than original Proto-Sound, you
should read these instructions thoroughly before using Proto-Sound® 2.0 features
in order to prevent harm to yourself or your equipment.
Proto-Sound® 2.0 features are activated by sequences of Bell and Horn button
pushes described below. Please read the full descriptions of each feature before
using it. To use these buttons to activate features rather than to blow the horn or
ring the bell, you should press the buttons firmly, but rapidly with a ½-second
pause between button presses. You may need to practice your timing to make this
work smoothly.

Operating Modes
1. Manual Mode
Upon initial power application, the engine will start up in manual mode. The chart
below lists the features available to the operator when in Manual Mode. Different
features are available when operating in Learn and Auto Modes, which are
described later.
Transit Announcement Sounds (TAS)
Your Proto-Sound® 2.0 model is equipped with operator controlled Transit
Announcement Sounds, hereafter known as TAS. This easy-to-use feature plays
digitally reproduced transit announcements and platform action sounds whenever
you activate and stop your engine. No additional wires or modifications are needed
on your layout to enjoy these amazing sound effects. These different sounds are
heard each time you give a long bell button press. The entire TAS sequence is
designed to simulate the arrival, disembarking, embarking, and departure of a
transit stop. The sounds include the driver announcing the stop and the upcoming
stop, passenger disembarking and embarking sounds, driver to passenger requests,
door openings and closing and general transit stop sounds. After the station
sounds have finished, the engine will shift back into gear and, if the throttle is set
high enough, will pull away from the station. To activate the TAS, press and hold
the bell button for approximately 2 seconds.
If you do not wish to stop at the station that is announced after activating TAS,
press and hold the bell button again without throttling down the train.

2. Learn Mode
In Learn Mode, the engine may be programmed with either an "Out & Back" route
or a "Loop" route. An "Out & Back" route begins at the 1st station (as
programmed by the operator), stops at intermediate stations, ends at the last
station, then reverses its route until it reaches the 1st station. A "Loop" route
begins at the 1st station (as programmed by the operator), stops at intermediate
stations, ends at the last station, and then begins the route over again at the 1st
station.

To program stations:
1. Running in Forward, stop the unit at the desired location for the first stop by
pressing the direction button. Note: if you stop the engine with the throttle
control, you must re-apply power so that the engine goes into neutral and does not
shut down.
2. Enter Learn Mode by pressing Horn - Bell - Bell - Bell - Bell. The train will then
announce that you have entered Learn Mode.
3. Press and hold the Bell button to scroll through the available stations until you
hear the one that you would like to be your first stop. Release the button quickly as
soon as you have heard the desired stop name.
4. Press and hold the Horn button until a "saved" response confirms that station's
location and name are saved in memory.
5. Proceed to the next stop by pressing the Direction button.
6. Press the Direction button to stop the train again when you have reached the
next desired station location.
7. Using the Bell button, select the name of the station, then save using the Horn
button.
8. Repeat steps 5-7 until you are ready to program the last stop in the route.
9. The manner of saving the last station in the route determines whether the route
will be an "Out & Back" or "Loop" route.
"Out & Back"
Follow steps 5-7 to save the last station. After you press the Horn button and
the sound system plays the "Saved" confirmation, press the Horn button
again. Another "Saved" confirmation will play and the car will exit Learn
Mode and enter Manual Mode.
“Loop"
Follow steps 5-7 to save the last station. Press the Direction button once to
start the car in forward and stop the car at the location of the first stop by
pressing the Direction button. Press the Bell button as many times as is
necessary to hear the name of the first stop. Press the Horn button until
the"Saved" confirmation is played. The car will then automatically exit Learn
Mode and enter Manual Mode.

Notes:
Always approach a desired station stop location while running in Forward.
Learn mode counts distance traveled, not actual physical locations. However,
unlike an automobile's odometer, Proto-Sound 2.0 Learn Mode does erase
distance when traveling in reverse. If you operate your car past the desired stop
location, you may back it up to the desired stop location, however you must put
the car into forward and then neutral again before saving the stop name and
location into memory.
3. Auto Mode
When you have finished programming your stations in Learn the car will be in
Manual Mode. Running in Forward, stop the car at the location of the first
programmed station by pressing the Direction button. Press Bell Horn Horn to
put the train into Auto Mode. Press the Direction button again to begin operation
in Auto Mode. Because Auto Mode operation begins at the first stop, the next stop
announced will be the second stop.
Notes:
The engine will always power up in Manual Mode.
