whistle button. To reset ProtoSounds to its original factory setting of no
horn in neutral, repeat the above procedure but keep pressing the whistle
button in Feature 25 until ProtoSounds only dings once instead of twice.
Note: When “Whistle In Neutral" is set, the bell will only operate with a separate bell button
and the horn will not sound in neutral if the transformer throttle setting is over 11 volts. At 11
volts or higher, ProtoSounds may arm the coil coupler for operation whenever the whistle
button is pressed and the engine is in neutral.
PROGRAMMING FOR PROTOCOUPLER OPERATION
ProtoSounds comes with a RESET feature that allows the operator to
remotely turn off the ProtoCoupler functions. This is especially useful
when double or triple-heading ProtoSound equipped engines since every
engine equipped with a
ProtoCoupler will fire when
prompted to by the operator.
By turning off the
ProtoCoupler operation on
certain engines, you can fire
the couplers open on the
other engines without
uncoupling the engines from
each other. To turn the
ProtoCoupler function off,
enter RESET and go to Feature 10. (See the section on Using RESET To
Program ProtoSounds® on page 18.) Once in Feature 10, press the
transformer whistle button and wait for ProtoSound to sound a bell ding(s).
Continue pressing the whistle button until ProtoSounds sounds two bell
dings (signifying that the ProtoCoupler option has been turned off). Simply
turn the transformer throttle off and then on again to lock in the new setting.
