MTH Big Boy Operating Manual
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 whistle 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.
