Function Keys
The following table lists features that have been pre-assigned to your DCC function
keys.
Operation of these keys can be different in the neutral state
(
locomotive
stopped) and
the
motive
states
(locomotive
moving in forward or reverse). After you have selected your locomotive, simply
press any of the function keys listed below to produce the described effects
.

Quantum supports the new
NMRA
0-12 function key standard; the
old
0-8 standard
is
not
supported.
If you have a DCC command station that supports only the older 0 to 8 function key standard
,
you
will have no way to initiate Shut Down in Neutral with these pre-assigned feature to function key
mappings. There is an interim solution to this problem; by changing CV 41 from its default value
of 32 to decimal 128, you can control Shut Down in Neutral from
function
F7 (instead of function
F9) on your DCC command
station.
In
Forward and Reverse
,
F7 will still
control
the locomot
i
ve
Air Brakes.
Directional Lighting Operation (F0 or FL or Headlight)
The FL (or
F0
,
or
Headlight)
key toggles the Directional

on
or off.
The defaults for Headlight/Reverse Light and Mars Directional Lights are off. When toggled on, the
Directional Lights

come on according to the table below.

Coupler and Coupler Crash Sounds (F3)
There are
two
ways
to
use
the
F3 key.
•
As
your engine is about to couple up to a string of cars, press the F3 key to trigger
t
he
crashing sound of engine coupling
.
Use
the
F3
key again as the engine moves out to
trigger
the same sound as
the
slack
is
taken up in
the
cars.
•
Use the
F3
key in
neutral
to
produce
uncoup
l
ing
sounds as
you
disconnect cars
over
uncoupler 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 sound of
the
coupler knuckle opening
and air-lines parting.

Explicit lighting control features for headlight
,
reverse
light
and
Mars
Light can beassigned to DCCfunction outputs.
(See
OSI DCC Reference Manual
,

Quantum
uses
constant voltage lighting that
is
independent
of track voltage.
