    QUICK START GUIDE Of course, you should read your manual over before running your engine. But if you just can’t wait, choose which control method that you use from the list below. Follow the steps outlined in your section, run your engine and enjoy! Now, after a few minutes, shut down the engine and read through your engineer’s guide.

  • Page 4: Unpacking Your Engine

    UNPACKING YOUR ENGINE Removing and Unwrapping Your Engine Slide the plastic packaging sleeve off of the container. Carefully remove blister (clamshell) on a soft surface. By nature, models with high levels of detail have some small fragile parts. Carefully remove any foam packing pieces that may be surrounding the model.

  • Page 5: Product Overview

    PRODUCT OVERVIEW Getting to Know Your M.T.H. HO Locomotive Key Features Your new HO Diesel Engine is equipped with the exclusive M.T.H. Proto-Sound® 3.0 digital sound and control system. In plain English, this means your locomotive contains state-of- the-art electronics providing realistic digital sounds, precisely controlled speed in increments of 1 scale mile per hour, and much more.
  • Page 6 Digital Control In standard analog DC mode, your model still operates under digital control. The PS 3 advance speed control system converts track voltage into digital speed commands. Your model will run smoothly and consistently at any speed regardless of load, hills, or curves. If you are a DCC user, you'll quickly learn to appreciate the precision of our speed control and linear speed curve.

    SET-UP Installing the Snow Plow Mounting Holes Slide the Snow Plow Up Through Completed Snow Plow Installation The Air Hoses And Press The Tabs Into The Holes Lubrication Using light machine or household oil, apply a very small amount to all axles points as shown. Your gearbox is properly greased at the factory and probably never needs service, however, if you run excessive hours pulling heavy loads, it's a good idea to remove the gearbox...

  • Page 9: Modes Of Operation

    MODES OF OPERATION There are 3 modes of operation with different levels of features accessible in each. We refer to them as Analog DC, DCS and DCC. Here’s a brief explanation of each mode. Analog DC This is when there is nothing connected to the rails except a conventional DC power pack.

  • Page 10: Features And Operation

    FEATURES AND OPERATION Now, for the fun stuff! Your new M.T.H. HO Diesel Engine has more features and operating capabilities than any HO engine ever built by any manufacturer. We're going to walk you through everything she does in general, but you'll probably find a few we forgot to mention on your own.
  • Page 11 Speed Control Your engine is equipped with speed control. This feature is always active, even in analog DC mode. Basically, your engine constantly measures track voltage and converts this to a digital speed command. You should notice the speed remains constant up and down grades, around curves, and with varying loads.

  • Page 12: Dcs Digital Command System

    DCS Digital Command System As you may have gathered by now, DCS is an M.T.H. exclusive Digital Command System that provides easy access to dozens and dozens of features in our models. We developed DCS to provide a powerful and advanced model train control system that was simple and enjoyable to use.
  • Page 13 Custom Sounds You can fire any of 10 individual sound bites pre-loaded into your engine. These are typically, diesel idling sounds. Each one at the press of a single button. You can also make voice or other audio recordings and play them back on command with ease.

  • Page 14: Dcc Digital Command Control

    DCC - Digital Command Control DCC is a popular digital command scheme wherein the track power is also a digital control signal. That is, using a DCC controller, you can communicate with multiple engines and have all of them moving at different speeds and in varying directions on the same track at the same time.
  • Page 15 Start-Up/Shut-Down F3 – Start-Up/Shut-Down Pressing this twice (toggle on then off) will start up your engine. When you apply DCC power your MTH PS3.0- equipped engine will remain dark and quiet. Since you likely don't want to run the engine this way, simply press F3 twice to start your engine.
  • Page 16 3. Press the F4 button twice (toggle F4 on then off) again to advance the sequence. You'll hear “Now boarding…” for passenger sound sets and freight yard sounds for freight sound sets. 4. Press the F4 button twice (toggle F4 on then off) again to advance the sequence.
  • Page 17 Engine Sounds F25 – Engine Sounds You can turn the Engine Sounds On/Off by pressing the F25 button. Pressing it once (enabling F25) will cause the Engine Sounds to shut off. The Whistle/Horn and Bell sounds will still be active, however. To turn the engine sounds back on press the F25 button again (disable F25).
  • Page 18 F21 – One Shot Doppler You can set your MTH PS3.0-equipped engine to simulate the actual Doppler Effect sound a real engine makes as it passes you. To do this, press the F21 button once (enable F21) and then listen as the engine makes that pitch shift that mimics the Doppler Effect perfectly.

  • Page 20 CV29 CV29 is the basic decoder setup CV that is used by all DCC decoder manufactures. So, if you are familiar with CV29 from other manufacturer's decoders MTH's is no different. The most important part of CV29 is the ability to switch between long and short addressing.
  • Page 21 To change your engine's Long Address using PoM: 1. Call up the current engine's address on your DCC handheld 2. Enter Programming on the Main on your DCC handheld 3. In this step you have to tell the MTH engine that you want it to start looking at long addresses.

  • Page 22: Factory Reset 55-55-55

    Feature/Factory Resetting Please note, when making setting changes in DCS or DCC, such as address, please wait a minimum of 5 seconds after removing power to insure the settings are stored in the engines memory. Reapplying power in less than 5 seconds may result in losing the setting changes.
  • Page 23 Below is the method (55-55-55 Reset) you can employ to return an engine to its factory default short address of 3 (it will also set the engine's long address back to its default – usually 3333 or the cab number on some models) if you're unsure of the engine's current address: •...

  • Page 27 User-Settable F-Function List This feature allows you to take the 28 F-Functions that currently reside in each MTH Proto-Sound 3.0-equipped O- Gauge Engine and change the location of that function. For example: F4 is currently PFA and you'd like that placed down to F28 which is Feature Reset.
  • Page 28 The above list includes ALL F functions that an MTH PS3 engine could have. You are free to change any of the above listed items to any F function position, 1-28. For example, if you your engine came from the factory without a smoke unit but you added one at a later date you could swap out any of the F functions, 1-28, for the Smoke On/Off and the Smoke Volume.

  • Page 29: Advanced Consisting

    Custom Speed Tables Below is a table that shows the value to write to CV25 to achieve the desired speed curve. For example, if you would like to use speed curve 18 then: 1. Write a value of 1 to CV52 to enable PWM Mode 2.

  • Page 31 7. Set CV22 to a value of 2 to the Rear engine's address to tell the Rear engine that you want to control its FL control with the F0 button at the consist address. The engine will give you two horn blasts to announce that it received the CV change 8.
  • Page 32 Setting Up CV21 for a Consist Cv21 allows you to set which F Functions you want the consist address to control. For example, you will likely want all of your MTH consist engines to respond to Start-Up/Shut Down (F3). Also, you'll likely want at your Front engine to respond to the Bell and Horn commands (F1 and F2, respectively) and the Front Coupler (F7 on most MTH models).

  • Page 33: Programming Track

    Programming Track Your MTH Proto-Sound 3.0-equipped locomotive does not program well on Programming tracks due to the inclusion of super capacitors utilized in the locomotive's electronic package. The super capacitors provide backup power to the electronics, allowing the locomotive to better negotiate track sections suffering from poor electrical conductivity.
