Installation
1. Before installing the sound module, the factory-equipped motor decoder must first be reset to factory defaults.
(If the model has never been run or its original CV settings have never been changed, this will not be necessary.)
To reset to factory defaults using your DCC command station, set CV 8 to a value of 8. Then cycle the locomotive’s
power by turning it off and back on. Turn the power off again and remove the locomotive from the track to proceed
with sound module installation.
2. Remove the coal load with metal fence from the tender by firmly grasping it and pulling it up and off.
3. Gently pull and remove the connector wires from the two LED legs from the lamp as shown in the photograph.
Note which color wire plugs into which leg (long or short) to ensure the correct polarity when they are reattached.
4. Remove the lamp by gently pulling it straight out.
5. Carefully line the sound module up with the like 21-pin connector on the circuit board within the tender.
The board will only mount one way as shown in the illustration. Take care not to bend any of the pins!
6. Once you are sure you have the pins and the connector properly aligned, press the module into place.
7. Reinsert the LED legs through the mounting holes. Make sure that the LED legs are seated correctly.
8. Re-attach the connector wires to the LED legs, making sure you connect the correct color wire to the correct length leg.
9. Re-attach the coal load with metal fence to the tender.
Note: If the lamp does not work, follow Steps 2-8 again, switching which wire gets connected to which LED leg (long or short).
Operation
This table is a partial list of the Tsunami's most commonly used CVs.
Please refer to the online Owner’s Manual for complete information.
If you are new to SoundTraxx Digital Sound Modules, you should start with the
User’s Guide
that will walk you through the various aspects of programming your sound module, as well
as some tips on troubleshooting. For the power user, the
Technical Reference
will provide a list of all the CVs available for use with your sound module and their exact function and
make-up for those who wish to have a complete reference for advanced programming techniques. These documents are available in PDF format on the Bachmann website
(www.bachmanntrains.com) and the SoundTraxx website (www.soundtraxx.com). Please note that you need to have Adobe
®
Acrobat Reader installed on your computer (available as a free
download from www.adobe.com) to open and print these files.
Your Digital Sound Module has been installed with all CVs pre-programmed so you can begin using your locomotive immediately without having to worry about what adjustments to make.
Items such as the exhaust chuff rate have already been calculated and optimized for the locomotive. The module is set to operate immediately using either a 12 volt DC power pack or
NMRA-compatible DCC command station.
Since CVs are pre-programmed for individual models to achieve the best possible sound and operation, default values will vary from locomotive to locomotive. You can find the default val-
ues for each model listed on the Bachmann website (www.bachmanntrains.com).
Operating with DCC
Your locomotive will respond to address 3 as it would if you had just installed any DCC decoder. Since these modules have two rather than four lighting outputs, we have made some changes
to the standard function assignments so that those using command stations with limited function keys can access some additional sound functions. The list below shows the function assign-
ments of the module. The User’s Guide located on either the Bachmann or SoundTraxx website will give you all the information you need to adjust your module to suit your taste.
For now, simply set your controller to Locomotive Address 3, place the locomotive on the track, and away you go!

Programming and Reading CVs
If your decoder is otherwise working properly (i.e., responds properly on the mainline to speed and direction commands) but your command station is having trouble reading CV data, it may
be due to incompatibilities between the electrical requirements of the decoder (which are different from conventional decoders due to the added audio circuitry) and the electrical character-
istics of your programming track. In such an event, you will need to use a Programming Track Booster, such as SoundTraxx PTB-100 (P.N. 829002). The PTB-100 amplifies the programming
track signals to levels that work best with Tsunami. It is easy to install (see next page) and inexpensive. An advantage to using the PTB-100 is that it also provides short-circuit detection and
some helpful diagnostics.

Operating in Analog Mode Using a DC Power Pack
While the sound system installed in your Bachmann model is primarily designed for operation by a DCC control system, it may be used on a DC powered layout. To operate in analog mode,
you simply control your locomotive using an ordinary power pack, although operation will be a bit different than when running non-decoder equipped locomotives.
With the power pack’s throttle set to zero, the sound module will be silent as it has no power. The throttle must be turned up to around 5 volts or so to provide sufficient voltage to power up
the internal circuitry of the module. At this point, you will begin to hear the background sounds such as the blower and airpump start.
Increasing the throttle further to around 7.5 volts or so will set the locomotive in motion, increasing speed as the throttle is turned up. Note that the direction of the locomotive can only be
changed when the locomotive is stopped.
