Extended Addressing
Most Command Stations will give you the option to enter a 4 Digit Extended Address. Please refer to your
Command Station’s Manual for guidance as to how to do this. If your command Station does not have this
feature a full list of values and instructions are available on line at www.loksound.com

While pulling a train a Prototype Locomotive will not move until the Prime mover has worked up enough power to
provide the proper amount of electricity to the traction motors. For this reason when the LokSound Select sound is
idling and you turn up the throttle, the locomotives begins to move only after the Diesel engine has reached
notch1. Although this behavior is very prototypical, one might not like it because it causes some delay. You can
disable this startup delay by simply Changing CV124 to a value of 0. This will cause the LokSound Select decoder to
immediately start moving when the throttle is turned up. However, the start up sound will not be prototypically
synced with the motion anymore.

You will notice quickly that the F8 button will work differently than what you may be used to. This is done for two
reasons. First so that you can hear both the start and Shut down sequences without any CV changes. Also so that
upon power up the drain on your command station is not as great. Sound decoders draw quite a bit of power upon
start up. Having the sound off initially when the layout is powered up is a much more efficient way on doing
things. This can save your command station from an early demise! You may be used to other manufacturers who do
this backwards. If you prefer you can easily reverse this feature in LokSound decoders. Simply Change CV32 to 2,
then CV403 to 32. Please note also that F8 only controls the prime mover sounds. On a real engine, as long as there
is air, the bell and the horn will work when the prime mover is off!

Decoder-Reset

Write value 08 into CV 08.

From time to time you may have the need to reset the
decoder in your new Locomotive. Setting CV08 to a
value of 08 will accomplish this. Be aware though that
all user settings will be set back to factory defaults
with this process. Your address will now become 03.

Sound Choices

This Factory equipped LokSound Digital Sound
Decoder was built specifically to be correct for the
Prototype of the model. You may find however that
you would like different Sounds. All sounds can be
changed with CV48 and your Command Station.
CV 48 is calculated by adding the Prime mover, the
horn, the Bell, and the brake squeal selection you
would like in your model. By adding your choices
from the charts above you will arrive at the value
to put in CV 48.

Default Example:
Prime Mover = 0
Airhorn = 1
Bell = 0
Brake Squeal = 0

Total = 1
CV48 Value = 1
