PROTO-SOUND
2.0 OPERATING INSTRUCTIONS

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 the 
reset state 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. 

Activating Proto-Sound 2.0 Conventional Mode Features:

Proto-Sound 2.0 features are activated by sequences of Bell and Whistle 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 
whistle or ring the bell, you should press the buttons for a shorter time (½
second); you may need to practice your timing to make this work smoothly.

Feature to Be Activated:

Passenger Station Announcements
Fire the Rear Coupler
Fire the Front Coupler
Speed Control On/Off
Lock into a Direction/Unlock
Reset to Factory Defaults

Button Code:

1 Bell, 2 Whistles
1 Bell, 3 Whistles

increase the volume and counter-clockwise to decrease the volume (see Fig.
