Cab Chatter
Sometimes the Cab Chatter sounds
don't play.
Lock-out
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.
Volume
The sounds seem distorted, especially
when the whistle or bell is activated.
FYS
The FYS sounds occasionally repeat
themselves.

Remedy
Cab Chatter plays only in neutral at
random intervals.
Remedy
The engine is locked into the neutral
position. Follow the procedure in the
"Lock into a Direction" section.
Engine speed must be below 10 scale
mph (approx. 10 volts or less in
conventional mode).
Remedy
Proto-Sound 3.0 volume is set too
high. Turn the volume control knob on
the bottom of the chassis counter-
clockwise to reduce the volume.
Remedy
Proto-Sound 3.0 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 FYS
sequence, it is probable that some of
these sound clips will be repeated
from time to time.
