F-3 A B A DIESEL ENGINE SET
Cab Chatter
Remedy
Sometimes the cab chatter sounds don t
play.
Cab chatter plays only in neutral at ran-
dom intervals
Lock-out
Remedy
I can t get the engine to run after I power
up the transformer. It sits still with the
engine sounds running.
The engine won t lock into forward, neutral
or reverse.
The engine is locked into the neutral
position. Follow the directions in to the
Lock into Direction State section.
Engine speed must be below 10 scale
mph. (approx. 10 volts or less in conven-
tional mode)
Volume
Remedy
The sounds seem distorted, especially
when the whistle or bell is activated.
Proto-Sound 2.0 volume is set too high.
Turn the volume control knob on the bot-
tom of the chassis counterclockwise to
reduce the volume.
Battery
Remedy
The engine will not leave the initial neutral
s
tate.
Iget no sounds when the engine shifts
between direction states.
After I turn off my transformer, my engine
continues to make sounds before quitting.
Check to be sure the battery is installed
and fully charged. See the Self Charging
Battery Back-up section.
The battery may be dead or need to be
charged. See the Self Charging Battery
Back-up section.
Proto-Sound 2.0 is designed to continue
to sound for a few seconds after the
power to the track has been shut off
.
PSA
Remedy
The PSA sounds occasionally repeat
themselves.
Once in PSA, the engine doesn t go into
reverse.
When the PSA enters its last sequence
the bell automatically comes on.
Proto-Sound 2.0 has a built in random
number generator that randomly selects
each sound clip to play. Because there are
a limited number of sound clips available
in each PSA sequence, it is probable that
some of these sound clips will be repeated
from time to time.
So that PSA effects can be as realistic as
possible, Proto-Sound 2.0 disables the
reversing unit whenever it is enabled. This
way the engine remains still at its stop as
the operator cycles through the PSA
sequences.
It is programmed to start ringing the bell at
that point. After approximately 12 rings of
