Sounds
In this mode, sound are pretty much automatic. If you're moving, you'll hear
diesel sounds.
When your sitting at idle, there may be some maintenance done. You could hear
someone calling for help on the radio. Don't worry, all of this and more is just a
normal part of everyday operations.
When your moving at a pretty good clip and you reduce the throttle quickly, you
may hear the brakes squeak and squeal as the engineer applies them. Of course,
they'll stop when the engine does.
If things get too noisy, just locate the sound volume pot under the rear roof
adjust the volume from maximum down to off, whatever suits you. Turn it
counterclockwise to reduce the volume or clockwise to increase it. Refer to page 7
for volume pot location.
Lighting
Now, this is an illuminating section (we couldn't resist). Your model is equipped
with a headlight, marker lights, operating ditch lights, and cab interior light.
The first thing to know about the lighting is there aren't any bulbs. It's all LEDs
so, if you look for a section on how to replace them, you won't find it. You
should never have to.
As with sounds, in analog DC mode, lighting operation is fully automatic.
They're always on and behave appropriately.
The headlight functions under rule 17 and dims when stopped for a time or while
backing up. Of course, just as you begin to move forward, it goes bright to show
the way.
The cab light is always on so the engineer can always see clearly.
