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
(telephone: 410-381-2580; fax: 410-423-0009; [email protected],

by
Starting Up
Remedy
When I first turn the power on, the engine will
not begin to run. I have to turn the throttle off
and on again to get the engine to operate.
This is normal behavior. To prevent
accidental high-speed start-ups, ProtoSound
2.0 is programmed to start up in neutral any-
time track power has been turned off for sever-
al seconds. See the “Basic Operation” section
for more details.
Horn/Whistle
Remedy
When I press the horn/whistle button, the bell
comes on instead.
I can’t get the horn to blow when I press the
whistle button.
Reverse the transformer leads.
You may be pressing the button too
quickly. Try pressing the horn/whistle
button more slowly, taking approximately one
full second to fully depress the button.
Bell
Remedy
When I press the bell button, horn/whistle
comes on instead.
I can’t get the horn to blow when I press the
whistle button.
The bell won’t work on a separate bell
button.
Reverse the transformer leads.
You may be pressing the button too
quickly. Try pressing the bell button more slow-
ly, taking approximately one full
second to fully depress the button.
Check the wiring of the separate button.
Bell
Remedy
When I try to fire the coupler, FYS starts.
The Proto-Coupler won’t let the engine uncou-
ple on the fly.
The coupler does not fire or stay coupled.
You are waiting too long between whistle
button presses.
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.
