Tuning your ‘A’ Class’ performance
MOMENTUM
Simulate the labored performance of a
locomotive pulling a heavy load with
momentum. Press L, M, or H (located under
CAB-1’s removable panel) for light, medium
or heavy momentum. The R2IR remembers
the setting until you change it. For delayed
response, use H. For quick response, choose L.
BOOSTING AND BRAKING
Use the BOOST and BRAKE command but-
tons for incremental control of speed
and
a
superior method for handling grades, stops-
and-starts, and more. Plus, using BRAKE in
the Command environment gives you a
bonus RailSounds effect—the ultra-realistic
sound of squealing brakes.
STALL
Make your ‘A’ Class feel more responsive by
setting a “stall” voltage. Get your locomotive
moving, then press SET; the ‘A’ Class will
stop. The headlight will flash, indicating it’s
in the SET mode. Turn the throttle clockwise
to get the engine moving, then decrease
speed until the locomotive just stops. Then
press SET again; the R2IR remembers the
stall setting until you change it. To clear
stall, press SET twice, holding it for one sec-
ond each time.
HIGH VOLTAGE SETTING
Press ENG, the locomotive ID#, then press
SET; the headlight will flash. Get your loco-
motive moving to the maximum speed you
want it to run, then press BOOST. Use this to
keep your locomotive from accidentally
being derailed at high speed.
To clear setting, press ENG,
the ID#, then immediately
press BOOST.
SOUND QUALITY
To achieve your preferred RailSounds mas-
ter volume level, use the volume control dial
located on the bottom of the tender (see page
6). Turn the dial left or right to adjust the
volume to your liking.
For quick remote-control of volume
below
the master setting—like muting—use the
CAB-1 numeric keypad’s volume control.
Pressing AUX1 and 4 on the keypad lowers
overall RailSounds output.
Maintaining your ‘A’ Class’ handrail antenna
Y
our ‘A’ Class’ handrails are more than
just model grab irons—they’re the
R2IR’s antenna for receiving Command Base
digital communications.
Please handle the
‘A’ Class carefully to avoid handrail dam-
age.
To ensure optimum reception, both
handrails are insulated from the die-cast
shell. If your ‘A’ Class experiences difficulty
receiving Base communications, check the
handrail ends in the cab and pilot for the
presence of insulating material. Ensure each
stanchion is present and enjoys a proper fit.
Finally, prevent the handrails from touching
any part of the die-cast locomotive cab.
These settings will be lost when you
assign a new engine ID number.
