MTH F3 Diesel Engine

USING “RESET" TO PROGRAM
PROTOSOUNDS®

  As mentioned earlier, there are several programmable options in each
ProtoSound-equipped engine that can be remotely set from any compatible
standard AC transformer equipped with a whistle button. For a list of
compatible transformers, see the chart on page 33. This hands-off approach
gives you unprecedented control of your railroad empire’s motive power
never before seen  in model railroading.  Each programmable feature can be 
accessed whenever your engine is in the RESET state as described earlier
on page 4.  By following the instructions below you will find the
programming easy and straight forward.

ENTERING RESET OPTIONS

  ProtoSound® is equipped with a few programmable features that are
accessed in the RESET state by moving the transformer throttle up and
down between full voltage and low voltage (6 to 8 volts) without shutting
the transformer off completely.  Each time this is done you advance, one
feature at a time, through the available options.   An air-release sound is
heard each time the throttle is advanced.  In addition, there are special
sounds to tell you what RESET position you are in.  

  For example, if you want to select Feature 2, you put the engine in
RESET, and move the throttle up and down from full throttle to low two
times.  After the second
advance, you will hear
two “clinks" indicating
that the computer is now
in Feature 2.  Advance the 
throttle again and you will 
hear three “clinks" for
Feature 3.  Advance it two 
more times and you will hear a “clank" indicating that you are now in
Feature 5.  Advance the throttle two more times and you will hear a “clank"
and two “clinks" indicating Feature 7.  ((5 throttle advancements = 1 clank)
+ (2 throttle advancements =  2 clinks)).  “Clank + “Clink" + “Clink" =
Feature 7.  You can advance the throttle as quickly as you like (though you
may not hear the air-release sounds) and the computer will still remember
the number of times the throttle is advanced by playing back the number of
“Clinks" and “Clanks" to confirm the feature you’ve selected.
