TrainMaster Command Control operations
Tuning your locomotive's performance (continued)
Speed RPM Mode (continued)
To enter Speed RPM Mode, press the AUX1, BRAKE key sequence while the locomotive
is stopped. A distinctive "clunk" sound will be heard. Once your locomotive is in Speed RPM
Mode, the RPMs will ramp up and down through its eight run levels depending on how fast
the locomotive is moving on the track. (Note that this is how your locomotive's RPMs are
controlled when it is running in Conventional Mode.)
To exit Speed RPM mode, reset the locomotive with AUX1, 0 key sequence or turn off the
track power and allow the locomotive to reset.
ADJUSTING THE SPEED
The BRAKE and BOOST buttons give you incremental control of your locomotive's speed
while you press and hold these buttons, allowing you to make small, gradual adjustments
around curves and over grades. The locomotive will resume its initial speed when the buttons
are released. Listen for the squeal of your locomotive's brakes when you use the BRAKE
button.
SOUND LEVEL
Press AUX1, 1 or 4 on your CAB-1 Remote Controller to raise and lower the volume of the
background locomotive sounds, such as RPMs and air release or let-offs. The horn, bell and
dialog will be unaffected. Note that this setting is preserved through power down and system
reset. Remember that the sounds will be silent when you power up your locomotive if the
sounds were turned down previously. To set the maximum volume of both the background and
foreground sounds, we recommend that you adjust your locomotive's volume control knob
(see Figure 3 on page 30 for the location).
