Analog DC Operation
The model and the sound decoder are
designed to be fully functional and ready
right-out-of-the-box with no adjustments
necessary. For operation using a Digital /
DCC system, refer to the section labeled
"Digital / DCC Operation".
Power Supply
Attention! The model should only be
operated on a high-quality, electronically-
regulated power supply providing 0 to
24 volts of smooth, filtered DC, with a
capacity of at least 2 Amps and a fast-
acting fuse or circuit breaker to protect
against short circuits. Do not use a power
supply which is not in safe and perfect
working condition. Older rheostat-style
power packs and "pulse" power packs will
result in erratic and unreliable operation
and should not be used. The use of an
improper power supply can even damage
the model and void the warranty.
Depending on the quality of the voltage
from the power supply, some automatic
sound functions may not work correctly
or may trigger continually. The sensitivity
of these functions can be adjusted using
a Digital / DCC system – See the Owners
Manual for further information.
Attention! Do not exceed the model's
absolute maximum input voltage rating
of 30 volts. If the track voltage exceeds
29 volts, the sound and motor will
automatically shut off and the front and
rear lights will flash. Decrease the voltage
immediately! The sound decoder will
recover at approximately 27 volts.

Operating the Model
With the throttle set to zero, the
locomotive will be motionless and silent,
as it has no power. Turn the throttle
up gradually to about 5 to 7 volts to
provide sufficient voltage to power up
the internal circuitry of the loco's sound
decoder. At this point, the sound of the
dynamo (generator) will be heard, as well
as the steady sound of the blower and
the occasional random pumping of the
air compressor. The smoke unit will begin
to work and the appropriate headlamp
(front or rear, according to the direction
of travel) will be lighted. If the throttle is
set to move the locomotive forward, two
blasts of the whistle will sound as the
throttle is increased. If it is set to move
the locomotive in reverse, three blasts will
sound.
Increasing the throttle further to about
8.5 to 9 volts will set the locomotive
in motion, increasing speed as the
throttle is increased. The exhaust chuff
is synchronized to the speed of the
locomotive. Note that the direction can
only be changed when the locomotive is
stopped. As the throttle is increased and
the loco begins to move, the bell will
automatically start and ring for about
5 seconds.
For best operation, adjust the throttle
smoothly and gradually. Erratic movement
of the throttle can produce poor operation.
When the throttle is turned down, the
sound of the brakes squealing will be
heard. A bit of practice may be required to
learn the rate of throttle decrease which
consistently triggers the brake sound.
Turning the throttle down further will bring
the locomotive to a stop, followed by a
single blast of the whistle and the hiss of
steam.
Leaving the throttle set to provide
about 6 volts to the track will keep the
sounds, lights and smoke operating
while the locomotive is stopped, such
as while standing at a station. A bit of
experimentation will reveal the proper
throttle setting to provide operation of
these "standstill" features. After a time,
the sound of the air compressor pumping
will be heard randomly. If the loco has a
simulated coal load, the occasional sound
of the fireman tossing a shovel or two of
coal into the loco's firebox will also be
heard. As set from the factory, this only
occurs about one of four times when the
loco stops.
Triggering Bell and Whistle Sounds
This loco also has a sensor to trigger bell
and whistle sounds when the loco passes
over track magnets (magnets not included
- purchase PIKO #35268). Rotating the
track magnet 180 ° will select triggering
either the bell ringing for about 5 seconds
or a grade crossing whistle signal
(two long blasts, one short, one long).
Volume Control
The volume control is accessed by gently
pulling off the front of the smokebox (the
front part of the locomotive's boiler).
Turn the knob carefully to adjust the
volume level.
Analog DC Features Requiring a
Digital/DCC System for Programming
This model is optimized from the
factory for best operation under most
circumstances. Advanced users of Analog
DC may wish to make use of a Digital
/ DCC system to change some of the
many programmable functions. Once
programmed on a Digital system, most of
these functions will also operate on Analog
DC. For example, using a Digital system,
one of three different whistle tones can
be chosen and this selection will remain
in effect when operating on Analog DC
power.
