Selecting the Sound Scheme on Your SDXN147A0: CV60
The SDXN147A0 comes preloaded with different sound schemes, 5 diesel

Selecting Horns/Whistles/Bells: CV150, CV157:
Scheme can be configured with one of 8 different horns using CV150, and
one of 4 different bells using CV157.
Each Steam Scheme can be configured with one of 3 whistles using
CV150 and one of 4 bells using CV157. To enable playable volume for
your selected horn or whistle add 128 to the selected value (ex. Playable
volume on horn 2 is enabled with a value of 130, 02+128=130)
Diesel Notching: CV132 and 155:
Sound CV155 is provided to select Diesel engine "notching" modes. The
default of CV155= 00 provides "automatic notching" that changes the
diesel RPM settings at 8 distinct throttle speeds that are configured by
Sound CV132 and follow speed directly.
Sound CV155=01 selects "semi-automatic notching" mode that allows F6
ON to increase the notch up from the current throttle setting and F7 ON
to decrease back down towards the lowest current throttle notch setting.
Sound CV155=02 selects "manual notching" mode that allows F6 ON to
increase the notch setting and F7 ON to decrease the notch sound setting,
irrespective of the throttle speed, which then controls just the motor
speed.
