RailSounds operations
Your locomotive's RailSounds system—the basics
L ionel RailSounds is the most realistic
model railroad sound system in the
world. Your locomotive features digital
samples from real-life diesel locomotives for
the ultimate in realism.
You may choose to install a nine-volt
alkaline battery in your locomotive. This
ensures interruption-free operation of
RailSounds. As illustrated in Figure 3, the
battery clip is located inside the body.
Remove the four body screws and lift away
the body to access the battery clip. Refer to
Figure 3. Battery installation and volume control knob location
Note!
Please remove the protective cover from the battery clip.
Although RailSounds is powered by track voltage, the battery is required for
Note!
uninterrupted operation and shutdown sequences. Use only alkaline batteries.
Discontinue locomotive power for ten seconds before changing the RailSounds
Note!
SND/NO SND switch position.
If RailSounds "drops out" during track power interruptions (for example,
Note!
during a direction change), replace the battery.
Figure 4 on page 17 to locate the screws.
The battery clip is illustrated in Figure 3.
When you first apply track power, the
locomotive's RailSounds system produces
sounds of the locomotive at rest. As the
locomotive moves, the RPM's increase with
the locomotive's speed.
To silence the diesel roar (the horn and bell
remain unaffected), slide the RailSounds
switch on the underside of the locomotive to
NO SND (refer to Figure 1 on page 5 ) before
powering up the locomotive.
