SOUND VOLUME SETTINGS
The sound volumes on your decoder have been pre-set at the factory to levels suitable for exhibi-
tion use. You will probably find the train
WAY TOO LOUD
for use at home or in your shed, unless
your home or shed is next to an active quarry or atomic test site. Fortunately all sound levels can
be easily adjusted to best suit your own requirements and we recommend that you experiment with
different settings if you don’t care for the default levels. The easiest way to turn the volume down
is simply to reduce the value of CV 63, which is currently set at its highest volume of 192. If you
want your APT-E to be even louder, we suggest strapping a 12” diameter speaker to the roof…
To set the volume levels go into the program mode on your DCC system (refer to your system’s
manual for instructions on how to do this as each system is slightly different); enter the desired CV
number; then enter the desired levels. Note that this can be done either on a programming track
or on the main (ops mode) if your DCC system supports programming on the main.
We strongly recommend that you keep notes on which settings you have changed and which
values were used. If you ever need to do a reset on the decoder (see “Factory Reset” below) then
having good notes will allow you to easily re-enter any changes that you might want to keep.
VERY IMPORTANT:
Before you change any of the volume control CVs (with the exception of CV
63), please make sure that CV 32 is set to 1. CV 32 is used as an index selection register and if
you don’t set it first then we are not responsible for your resulting rage and the fact that you will
probably throw the locomotive against the wall in frustration.
