*Note- The Bell [F1] Dynamic Brake [F6] and Rail-Wheel Clack [F10] can not be played simultaneously-the Bell sound will interrupt the other two sounds.

*Note- Because this locomotive has a dual function sound decoder on-board, it does not support CV read back features.This decoder supports all program methods including: register mode, paged mode, CV pro-gramming mode, direct mode, and program-ming on the mainv [OPS mode programming]. Program the locomotive the same way you would program any other NMRA compatible decoder with your DCC system.

Out Of The Box DCC RunningThe first time you run your new SD45-2 loco-motive there are a few steps you should take to make sure the locomotive operates properly:

Test the locomotive in it’s analog mode [D.C.] if possible. If it runs properly [lights, sound, forward and reverse] on D.C., it will run trouble free on DCC.The locomotive comes with a factory de-fault DCC address of #3. Before program-ming a new address into the locomotive, test run it on your DCC system on address #3. This will also insure there are no prob-lems with the locomotive.Test all functions [lights and sound] on default address of #3. Use the supplied Function Chart.

To avoid a current overload on your DCC system when starting it up with a lot of sound equipped locomotives on your layout, your new Athearn Genesis SD45-2 locomotive does not automatically start up in the DCC mode. To start the locomotive, in Run Mode, enter the address you have assigned for the locomotive, then press any function button [F1-F9] two

times (do not press F0 2 times or you will shut off the sound). You will then hear the locomotive go through it’s start up procedure [there will be no movement or operating functions for a few seconds until the locomotive’s idle steadies out]. Once your locomotive finishes it’s start up, it is ready to go to work on your layout.When you are finished running your locomotive, pressing function button 8 [F8] four times will shut your locomotive down. When the locomo-tive is shut down this way, it will not automati-cally start up next time you need it. You will have to press any function button 2 times to re-start it.

Once these steps have been completed, fol-low the included CV chart to program any new programming features you want into the loco-motive. When you initially program your new SD45-2 locomotive, this step should be done on a program track for best results. You must know how to properly use your DCC systems programming mode to program any decoder. If you are unsure of programming a decoder with your system, please consult your DCC systems instruction book regarding programming or contact the manufacturer of your DCC system for proper guidance.

GENESIS SD45-2 WITH DC/DCC

SOUND SYSTEM

Genesis SD45-2 Locomotive Instruction GuideYour 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 ModeThe 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 ModeTo 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 circuitrymay “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 VolumesIn 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 DefaultsIn 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 ModeYour 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.
