Whistle
and Bell Buttons (F2, F1)
Some DCC controllers have separate whistle and bell buttons along with
function keys assigned to whistle and bell operation. The whistle is usually
assigned to F2. The F2 key behaves differently than using the whistle
button.
•
Pressing the F2 key and releasing it will cause the whistle command
to come on and stay on, until you press F2 again.
•
Pressing the whistle button will blow the whistle only as long as you
are holding it down.
Pressing the F1 key and releasing it will cause the Bell to come on and stay
on, until you press F1 again. There is no difference in operation between the
bell button and its corresponding function key.
Doppler Operation (F6)
With DCC, you can trigger the Doppler effect by quickly interrupting the
whistle signal in the same way it is described under Analog control. Or you
can use the function key dedicated to the Doppler effect.
•
Start the Whistle and/or Bell by pressing and releasing their function
keys

Squealing Brake and Flange Sounds (F7)
•
Quantum provides automatic brake squeal as an engine slows to a
stop. The operator can also control squealing sounds for continuous
and variable brake sounds for protracted stops or to simulate the
sounds of squealing wheel flanges on curved track.
•
Squealing Brakes come on automatically when the speed is reduced
from high-speed travel (over 40 smph) to less than 20 smph.
•
Pressing the F7 key when the engine is moving at any speed will
manually activate Squealing Brake sounds, and repeated pressings
while the Squealing Brake sounds are occurring will continue the
sounds uninterrupted.
Note:
If you slow the engine too quickly, the brake sounds will terminate
abruptly when the locomotive stops and enters Neutral.
Note:
If you lower your throttle to speed step 0 on a moving locomotive, the F7
