2.4.1 Adjusting Volume
Important: This potentiometer is
located on the upper sound
effects electronic circuit board.
Under no circumstances should
you confuse this potentiometer
with one of the potentiometers on
the lower digital circuit board for
adjusting the running characte-
ristics of the locomotive.
Turning the potentiometer to the left:
softer
Turning the potentiometer to the right:
louder
This potentiometer has a stop at the
two end points. Never try to turn the
potentiometer with force past these
stops.
2.4.2 Coding Switches on the
Sound Effects Electronic
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
settings 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 Off Off On On On On
