of the whistle. QUICKLY TURN THE POWER BACK ON AGAIN. Your
engine is now locked into NEUTRAL.
NOTE
: When locking the engine in the Forward or Reverse positions, the whistle button will
blow the whistle. But when locking the engine into the NEUTRAL position, the whistle button
may turn on or off sounds of the bell, coupler arming or coupler firing depending on the
transformer throttle voltage settings prior to the users attempt to lock out the engine.
Remember, the whistle doesnt blow in NEUTRAL (unless you programmed it to do so using
Feature 25. See page 21 for details), only the bell rings or the coupler operates in NEUTRAL.
While it doesnt make any difference on how the lockout function operates, you may hear one
of the three different NEUTRAL-activated sounds.
To unlock the engine from the NEUTRAL position, follow the process to
unlock the engine in the Forward or Reverse directions above.
MANUAL REVERSE UNIT LOCKOUT
(Non-ProtoSound® Equipped Engines)
Engines not equipped with ProtoSound® can be manually locked into
Forward, Neutral or Reverse by sliding the lockout switch located on the
tender chassis to the OFF position after entering the desired reverse unit
direction state (See Figure 6 on page 17). To operate the engine in
automatic mode again, simply slide the switch back to the ON position.
Note: Once the unit is locked out and an hour or more of non-use has passed, the reverse unit
may cycle into any of the three directional states. Should this occur, the ON/OFF switch
should be reset to the ON position to regain normal operation.
