MTH E-8 Operating Manual
you are in neutral, you can blow the horn with the transformer 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 Horn 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 17.) 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.
PROGRAMMING FOR PFA OPERATION
ProtoSounds® is equipped with a RESET setting to turn off the Passenger
Station Sound Proto-Effects (PFA) features. This is especially useful if you
are double-heading engines that are both equipped with PFA. You may not
want to stop at a yard and have both engines playing their PFA sound
effects. To turn off PFA, enter RESET and go to Feature 28. (See the
section on Using RESET To Program ProtoSounds® on page 17). Once
in Feature 28, press the transformer whistle button and wait for
