The volume control switch has three wires: the two outside wires are installed in
positions 6 and 8 in terminal block P1 and the
center wire is installed in position
7. After all co mpo nents are
installed and your system has
power, you can set the volume to
your liking, by pushing the toggle in
one direction for increase (toward
position 6) or the opposite direction for decrease (toward position 8). Simply hold
the toggle in the chosen position until the volume reaches the level you desire. The
system "remembers" your selection each time you start up. Page 10 in your full
manual gives additional information.
Your Bachmann Shay has a special place for the volume control switch that makes
it readily accessible when you wish to adjust the volume.
On the outside of the tender, look at the cab end of the
coal load, on the engineer's side of the train. There is a
small water valve fitted with a lid that has a crank handle.
The lid pulls out to expose a hole, the perfect spot for
the toggle lever of your volume control switch! [Please
note: in later versions of the Shay, the crank handle
cylindrical support may be glued to the tender body.

Place the 64-1883 magnets 3/16-inch
form the edge of the rail, between the ties, as
