Operation
2.5 Adjusting the Sound
Effects Circuit
First remove the roof for the following
adjustment work. (=> Page 39). The
upper circuit board of the two circuit
boards is the sound effects electronic
circuit on which you can carry out the
following adjustments.

2.5.1 Adjusting Volume

Important: This potentiometer is
located on the upper sound effec-
ts electronic circuit board. Under
22
no circumstances should you con-
fuse this potentiometer with one of
the potentiometers on the lower
digital circuit board for adjusting
the running characteristics of the
locomotive.
Turning the potentiometer
to the left: louder
Turning the potentiometer
to the right: softer
This potentiometer has a stop at the
two end points. Never try to turn the
potentiometer with force past these
stops.
2.5.2 Coding Switches on the
Sound Effects Electronic
Circuit
Caution: Changing the settings
made at the factory can lead to the
destruction of the sound effects
circuit.
The sound effects electronic circuit is
set up for each model with the 8
coding switches. The appropriate
settings for your model were made at
the factory. No changes in these set-
tings are therefore necessary.
Important: These coding switches
are located on the upper electronic
circuit for sound effects. Under no
circumstances should you confuse
them with the 10 coding switches
for setting the address and the
mode of operation on the lower
digital electronic circuit.
The 8 coding switches are set at the
factory as follows:
Switch 1 2 3 4 5 6 7 8
Setting On On On On On On On On
