Troubleshooting Proto-Sound® 2.0 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-

Coupler
Remedy
The Proto-Coupler™ won’t let the
engine uncouple on the fly.
The coupler does not fire or stay
coupled.
Try lubricating the coupler knuckle
with a dry graphite lubricant. Do
NOT use oil.
The coupler needs to be cleaned.
Wipe with denatured alcohol (not
rubbing alcohol) and let dry.
Cab Chatter
Volume
Battery
Remedy
Remedy
Remedy
Sometimes the Cab Chatter
sounds don’t play.
The sounds seem distorted,
especially when the whistle or bell
is activated.
Cab Chatter plays only in neutral
at random intervals.
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.
After I turn off my transformer, my
engine continues to make sounds
before quitting.
Proto-Sound® 2.0 is designed to
continue to sound for a few
seconds after power to the track
has been shut off.
FYS/PSA
Remedy
The FYS/PSA 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 FYS/PSA
sequence, it is probable that some
of these sound clips will be
repeated from time to time.
