PROGRAMMING FOR HORN IN NEUTRAL
OPERATION
If you are operating your engine with a separate bell button and want to
blow your horn when your engine is in neutral, you will need to program
ProtoSounds® to do so as the factory setting only allows the horn to blow in
forward or reverse. To do this, enter RESET and go to Feature 25. (See the
section Using RESET To Program ProtoSounds® on page 17.) Once in
Feature 25, press the transformer whistle button and wait for ProtoSounds®
to sound a bell ding(s).
Continue pressing the whistle
button until ProtoSounds®
sounds two bell dings
(signifying that
ProtoSounds® has been
programmed to sound the
horn in neutral). Turn the
throttle off and then on again
to “Lock-In" your selection.
