4.1.2 Bell (F1 Key)
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 (
F1
).
4.1.3 Horn (F2 Key)
Some DCC throttles have separate
Horn
and
Bell
buttons along with the normal Function keys assigned to
Horn
(
F2
)
and
Bell
(
F1
) operation. The
Horn
is usually assigned to Function
F2
. The
F2
key behaves differently from the
Horn
button.
•
Pressing the
F2
key and releasing it will cause the
Horn
to come on and stay on, until you press
F2
again
38
.
•
Pressing the
Horn
button will blow the
Horn
only as long as you are holding the button down.
4.1.4 Coupler and Coupler Crash Sounds (F3 Key)
There are two ways to use the
F3
key:
•
As your locomotive is about to couple up to a string of cars, press the
F3
key to trigger the crashing sound of
locomotive coupling. Use the
F3
key again as the locomotive moves out to trigger the same sound as the
slack is taken up in the cars.
•
Use the
F3
key in
Neutra
l to produce uncoupling sounds as you disconnect cars over uncoupling magnets.
Press the
F3
key once to produce the sound of the lift bar and coupling pin being raised. This also arms the
uncoupling sound effect. Press the
F3
key again while moving or in
Neutral
to trigger the sounds of the
coupler knuckle opening and the air-lines parting
4.1.5 Diesel Fans and Louvers (F4 Key)
Pressing the
F4
key and releasing it will cause the sounds of the
Diesel Fans
and
Louvers
to come on and stay on
until you press the
F4
key again.
35
Explicit lighting control features for the
Front Headlight
,
Rear Headlight
, and (optional)
Ditch Lights
or
Mars Light
can be assigned to DCC
function outputs. (See the QSI DCC Reference Manual
[3]
.)
36
Quantum uses constant voltage lighting that is independent of track voltage.
37
The
Rear Headlight
cannot
be dimmed with Quantum Q1a hardware and Version 7 firmware; it is either
Off
or
On
. However with either Quantum
Q2 hardware and Version 7 firmware or with Quantum Q3 hardware and Version 8 or 9 firmware, the rear headlight
can
be dimmed, as shown in
the tables above.
38
Since a prototype Horn uses compressed air, you may hear the air pump sounds turn on after the Horn is operated.
