USING “RESET" TO PROGRAM PROTO-SOUND®
Proto-Sound® is equipped with several programmable features which are
accessed in the RESET state by moving the transformer throttle up and
down between full voltage and low voltage (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 and returned. In
addition, there are special
sounds to tell you what
RESET position you are
in.
ENTERING RESET OPTIONS
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.
