CHUFF RATE
Your locomotive is equipped with DynaChuff, the realistic steam chuffing sounds produced
by the RailSounds 5.0 sound system. Your locomotive’s chuff rate is always synchronized with
the motion of the drive wheels and the speed of the locomotive. The chuff intensity is also
capable of varying automatically with the speed of the locomotive in automatic chuff mode, or
you may choose to set a constant, or fixed, chuff intensity in manual chuff mode.
Automatic Chuff Mode
When you first throttle up, the intensity of the chuff sounds will vary with adjustments to the
throttle. When you stop the locomotive for two seconds or more, the sounds will return to their
initial intensity.
The initial chuff intensity simulates the sounds of the locomotive pulling a heavy string of
cars. Keep in mind that you may choose to reduce the initial intensity of the chuff sounds to
simulate a lighter load on the locomotive by pressing the
BRAKE
button while your
locomotive is at rest. This will reduce the initial chuff intensity to the lowest level.
Manual Chuff Mode
Manual chuff mode allows you to set a constant chuff intensity for your locomotive. The
intensity of the chuff sounds does not vary with the throttle settings or the speed of the
locomotive.
To set a constant chuff intensity, get your locomotive moving, then press
AUX1
,
3
or
AUX1
,
6
to enter manual chuff mode. The locomotive will be locked at the current chuff intensity. To
adjust this chuff intensity, press
3
to increase the intensity of the chuffing or press
6
to decrease
the intensity of the chuffing. The locomotive will save your intensity level.
If you press
AUX1
,
3
while the locomotive is at rest, the chuff rate will be set to the
maximum intensity. If you press
AUX1
,
6
while the locomotive is not in motion, the chuff
rate will be set to the lowest intensity. Once your locomotive is in motion, you may use the
3
and
6
buttons to increase and decrease the intensity of the chuff sounds.
When you press
AUX1
,
3
or
AUX1
,
6
, you have a ten-second “window” to adjust the chuff
intensity. During this time, the water injector (
3
) and steam blow-down (
6
) sounds will not
be triggered by the
3
and 6 buttons. After ten seconds, the
3
and
6
buttons will be reassigned
to activate the sounds. To adjust the chuff intensity after the ten seconds have elapsed, simply
press
AUX1
,
3
or
AUX1
,
6
again.
To exit manual chuff mode, turn off track power and allow the locomotive to reset, enter the
shutdown sequence (
AUX1
,
5
), or reset the locomotive (
AUX1
,
0
).
The water injector sounds (
3
) and the and steam blow-down sounds (
6
) are
inactive during the first ten seconds of entering manual chuff mode. These sounds
are restored after the ten seconds have elapsed. If you wish to adjust the chuff rate
again, press
AUX1
,
3
or
AUX1
,
6
to open another ten-second programming
“window.”
