Genesis SD45-2 Locomotive Instruction Guide
Your new Genesis SD45-2 Diesel Locomotive
comes factory equipped with a state-of-the-art
Dual Function decoder. This enables your loco-
motive to operate with any NMRA compatible
DCC system, as well as with any regular DC
Train Control [HO power pack]. It will automati-
cally sense the type of control you are using
without you having to set it up for the required
operation.
Caution: Do not run your new Genesis SD45-2
Diesel Locomotive with power packs intended
for “G” scale [do not exceed 18 VDC] as you
may damage the locomotive circuitry. Also,
never operate your locomotive with a trans-
former designed for use with AC powered
model trains [such as O-27 trains or some
European HO models].
Some DCC systems also come equipped with
a switch for extra voltage for larger scales
[“O” or “G”]. If you use your locomotive on
this setting damage will occur to the on-board
electronics due to the higher constant track
voltage [22 volts].
DC Operation- Analog Mode
The wireless remote transmitter [included] is
powered by a 12 volt battery [#A23.12].
One battery is included, replacement batter-
ies are readily available at electronic or office
supply stores.
There are certain conditions that will affect the
range of the transmitter [atmospheric, metal
piping, any type of metal screening used on
the layout, etc.]. For best operation it is advis-
able to place the transmitter antenna close to
the rails as you operate your locomotive.
This model will operate with a standard analog
DC power pack. However, the locomotive’s
sound will not begin until the throttle is at
approximately 50% of the throttle setting. The
locomotive will begin moving when the throttle
has been turned about 60%. The wireless
remote transmitter features six buttons that
control various sounds:
Button 1 will start or stop the bell ringing.
Button 2 will blow the air horn – the length of
time the button is held determines the length
of the horn blast.
Button 3 activates the sound of couplers con-
necting.
Button 4 controls the brake release sound
(when the engine is in idle) or brake squeal
(when the train is moving).
Button 5 turns the dynamic brake sounds on
and off.*
Button 6 allows you to turn off the headlight,
useful for when a locomotive is in idle.
*Dynamic Brake Sound- [Analog D.C. or DCC
Operation]:
When the dynamic brake sound is turned off,
there will be an approximate delay of 2 seconds
while the sound fades. [Pressing the button
again before the sound fades will reactivate the
dynamic brake sound unnecessarily.] Note that
the dynamic brake sound cannot be operated
while the bell sound [button 1] is ringing.
A unique feature of the dynamic brake sound
is that when activated the diesel prime mover
sound will automatically notch down to the idle
setting. This is true to life, as the engineer of a
real locomotive will put the prime mover into
idle when the dynamic brakes are activated.
This does not affect the speed of your locomo-
tive, but you can use your throttle to slow the
locomotive as it would in real life. When the
dynamic brake is deactivated the prime mover
sound automatically notches back up to your
present throttle setting.

Programming - Analog Mode
To program the various sounds, please follow
the following steps:
Turn on the power pack. Move the throttle
slowly up until you hear the prime mover
sounds start, make sure the loco is in idle.
Turn off the power switch [leaving the
throttle setting as is] and wait 2 seconds.
Press and hold Button #6 while you turn
the power switch to ON. When you hear the
locomotive say “Program” quickly release
Button #6, wait 5 seconds before pressing
any other buttons. Note: Program Mode is a
slow process. Always wait 2 seconds after
pressing a button. Do not press two buttons
within that 2 second lag time, and do not
press and hold a button while in the Pro-
gram Mode, as the circuitry
may “read” that as the button being
pressed twice, causing an error. While in
the Program Mode you will only be able to
perform approximately 30 program opera-
tions.
To return to the Run Mode, turn the power
pack’s ON/OFF switch to off, then wait 2
seconds before turning the power pack
back on.
While in the Program Mode, press Button
#1 to change the bell type- there are eight
types, plus“OFF” from which to choose,
and you will hear a sample of each bell
type ring four times each time Button #1
is pressed. After you hear the bell type you
like, or “OFF”, stop pressing Button #1.
Utilize Button #2 to choose from 15 different
air horn sounds plus “OFF”. Each time you
press Button #2 you will hear a sample of
the horn sound, stop pressing Button #2
when you hear the horn sound you desire or
“OFF”.
Button #3 turns the coupling sound “ON”
[sound heard] or “OFF”.
Button #4 can be used to alter the rate at
which the bell will ring.
Button #5 is used to turn all lights on or off.
While in the Program Mode, press Button
#5 once, you will hear the locomotive say
“Program”. This confirms that when you
re-enter the Run Mode the lights will be
off. To turn the lights back on, re-enter the
Program Mode, press Button #5 and again
the locomotive will say “Program”. This
will confirm that when you re-enter the Run
Mode, the lights will be turned on.
The “OFF” features are useful when the lo-
comotive is a trailing unit in a multiple unit
consist, and only the leading locomotive’s
lights and accessory sounds are needed to
be activated by the remote transmitter.
Program Sound Volumes
In the Program Mode you may individually ad-
just the volume of 5 sounds [Buttons 1 through
5]. To adjust the volume, press Button #6
[you will hear the locomotive say “Program”]
and then select one of the sounds [Buttons 1
through 5]. Each sound has four volume level
settings. For example, to adjust the volume of
the bell, press Button #6 [you will hear “Pro-
gram”] wait 2 seconds and then press Button
#1. At this point, you will hear a sample of the
bell sound in order to judge the
volume. Repeat
pressing Button #6 and, two seconds later,
But-
ton #1 to hear the next volume level, stopping
when the desired volume level is heard.

Note- There is a manual volume pot located
on the top of the circuit board. The adjustment
is set from the factory at full. To lower the
volume manually, use a small screwdriver and
turn the pot slowly clockwise until the desired
volume is obtained. There is no “stop” posi-
tion on the pot. If you continue turning the pot
clockwise, the sound will completely shut off,
then go back to full volume.
Restoring Factory Defaults
In the Program Mode, press Button #6 five
times [press, wait for “program”, wait 2 sec-
onds, press Button #6 again, listen for “pro-
gram”, etc.].
Once done the locomotive will go into it’s start-
up mode and be ready to run when the throttle
is advanced.
Programming –DCC Mode
Your Genesis SD45-2 Locomotive will operate
on any NMRA compatible Digital Command
Control [DCC] system. The highly advanced
dual-function decoder has the following fea-
tures:
Synchronized diesel engine sound with as-
sociated random locomotive sounds.
1.5 amp capacity.
Programmable for either 2 digit [1-127] or
4 digit [1-9999] addresses.
Programmable start voltage.
Programmable acceleration rate.
Programmable deceleration rate.
