Troubleshooting Proto-Sound® Problems
Although Proto-Sound® 2.0 has been designed and engineered for ease of use,
you may have some questions during initial operation. The following table
should answer most questions. If your problem cannot be resolved with this
table, contact M.T.H. for assistance (www.mth-railking.com, e-mail: parts@mth-

Starting Up
Bell
Remedy
Remedy
When I press the horn button, the bell comes on
instead.
I can't get any sound to play when I press the horn
button.
When I press the bell button, I get a station stop
announcement, not the bell.
You are holding the bell button too long. Press it for only
about one second to trigger the bell.
That is normal for this model.
You may be pressing the button too quickly to trigger the
bell. Try pressing the horn button more slowly, taking
approximately one full second to fully depress the button.
Platform Action Sounds
Remedy
Sometimes the Platform Action Sounds don't play.
Platform Action Sounds play only in neutral at random
intervals.
Lock-out
Remedy
I can't get the engine to run after I power up the
transformer. It sits still with the diesel and
compressor sounds running.
The engine won't lock into forward, neutral, or
reverse.
The engine is locked into the neutral position. Follow the
procedure in the "Lock into a Direction" section.
Engine speed must be below 10 scale mph (approx. 10
volts or less in conventional mode).
Volume
Remedy
The sounds seem distorted, especially when the
bell is activated.
No Sound
Proto-Sound 2.0 volume is set too high. Turn the volume
control knob on the bottom of the chassis counter-
clockwise to reduce the volume.
Volume is set too low, adjust volume control knob on the
bottom of the chassis clockwise to increase the volume
or check connector to speaker.
Battery
Remedy
The engine will not leave the initial neutral setting.
I get no sounds when the engine shifts between
directions.
After I turn off my transformer, my engine
continues to make sounds before quitting.
Check to be sure the battery is installed and fully charged.
See the "Self-Charging Battery Back-Up" section.
The battery may be dead or need to be charged. See the
"Self-Charging Battery Back-Up" section.
Proto-Sound 2.0 is designed to continue to sound for a
few seconds after power to the track has been shut off to
allow for a more realistic shut-down.
TAS
Remedy
The TAS sounds occasionally repeat themselves.
Proto-Sound 2.0 has a built-in random number generator
that randomly selects each sound clip to play. Because
there are a limited number of sound clips available in
each TAS sequence, it is probable that some of these
sound clips will be repeated from time to time.
