Quantum Engineer™ Operating Instructions
Quantum Engineer Controllers are designed to easily and quickly operate locomotive
features that have QARC (Quantum Analog Remote Control) technology. Except for
simple horn and bell operations, the Quantum Engineer Control is not suitable for older
Quantum locomotives that do not include QARC technology (see your locomotive
Operation Manual).
Introduction
The Quantum Engineer buttons are organized by function to make operation simpler.
The buttons on the right are the Primary Control Keys for locomotive operation and
include horn, bell and brakes.
The set of fifteen gray keys to the left of the Primary Control Keys, are the Locomotive
Feature Keys, and provide operation of different locomotive settings such as lights and
fans, as well as controlling different effects like Doppler and Flange sounds.
The cluster of five keys in a star pattern in the upper left corner is used for two different
types of control. During operation, the vertical arrow keys control sound volume, and the
left/right arrow keys select the throttle mode. During programming, the arrow keys select

the different program options and allow you to change the settings. This group of five
keys is called the Star Pad Keys.
The keys in the lower left are used to control the locomotive states of Start Up, Shut
Down, Disconnect and Standby as well as locomotive Status reporting. This group is
called the Locomotive State Keys.
Note: Some keys have a small triangle in the upper right corner. These keys turn the
indicated feature on or off using a special technique: pressing these keys once will turn
the feature on while pressing it twice in quick succession (double-pressing)
1
will turn the
feature off. This allows you to know whether you have turned a feature on or off without
having to see or hear the locomotive. The only exceptions are the Start Up and Shut
Down keys where a double press produces an extended Start Up or extended Shut
Down sound effect.
Installation
Wire the Quantum Engineer to your power pack's variable DC output and to the track as
shown in the diagram below. The red wires connect to the power pack’s variable DC
output (throttle) and the black wires connect to the track.
Remove the backing from the loop side (fuzzy side) of the Velcro tape and
press it to the bottom of the Quantum Engineer. Remove backing from the
hook side of the Velcro tape and attach it to your power pack or to a
convenient place in your control area.
The unit will be in Run Mode
2
as soon as power is applied. In Run Mode the Bell and
Horn buttons will operate normally, and the red LED will shine steadily. Your unit is
ready to operate.
1
Like double-clicking a mouse button on your computer.

Operation in Run Mode
If Quantum Engineer has been installed correctly, the red Power Light will glow steadily
when the throttle is turned up.
The following is a list and explanation of the features for the four different key groups.
Primary Operation Keys
Pressing the Horn key will produce Horn or Whistle blasts as long as
the button is pressed. If you press and release it quickly, you will get a
short “Hoot” sound.
Note: Some Quantum locomotives have special Horn Endings that can
be triggered by releasing the Horn key and then quickly pressing and
releasing
3
or tapping the Horn key before the Horn sound quits. This
special effect can also be performed by releasing the Horn key and
quickly pressing the Bell key. (See your locomotive’s Operation Manual
for additional information on Doppler and special Horn Endings.)
Pressing and releasing the Bell key will toggle the locomotive’s Bell
effect on or off.
Apply Brakes and
Release Brakes You can apply brake effects with the Apply Brake button in
RTC (Regulated Throttle Control) or STC (Standard Throttle Control)
4
although RTC provides more realistic control
5
.
Without reducing the track voltage, press and hold the Apply Brakes
key. Hear air being released from the brake pipes continually. The
longer the air is released the greater the braking action. Diesel motor
3
Do not confuse this with a Doppler action, which is triggered by quickly releasing and pressing the horn key
during horn operation.
4
A Load value greater than “0” must be programmed in Program Option 2 (POP 2) and the Load must be
activated using the Load On/Off key in order for the Apply Brake key to have any affect in STC. RTC does not
require a Load value for the braking features to operate.
5
See description of RTC and STC in the Quantum Operation Manual supplied with your locomotive.

Quantum Engineer Operation Manual, Ver. 2.0.1 6/24 19 September 2006
sounds will automatically reduce to idle and steam chuffing will reduce
to its lowest Sound of Power®setting.
Let go of the Apply Brakes key to stop the air release. The train will
continue to slow at the last braking value.
Note: If you initially press the Apply Brakes key only briefly, you will
hear no air release sound and the locomotive will coast to a stop at its
Intrinsic Inertia
6
and Load setting without any braking applied.
If you want to apply more braking, press and hold the Apply Brakes
key to release more air. When you reach the desired amount of
braking, let go of the Apply Brakes key to stop the air release.
Press the Release Brakes key to release the brakes to return the
locomotive to coasting.
Press the Release Brakes key a second time and hear the Diesel
Motor or Steam Chuff return to its pre-braking throttle setting. The
locomotive will accelerate back to its original speed at a rate
proportional at its Intrinsic Inertia and Load setting.
Note: Apply Brakes will have no affect in STC unless the locomotive
has an active Load value (see Load On/Off on page 7).
Note: You will only need to press the Apply Brakes key once after the
locomotive has stopped to return to original speed
7
.
Note: If the locomotive is in Neutral when the Apply Brakes key is
pressed, a Long Air Let-off sound simulates setting the brakes.
However, no braking effect is activated
8
.
Note: If you apply brakes at a high throttle setting, the locomotive will
often come to a much smoother stop than simply lowering the throttle.
Note: When a locomotive is stopped with brakes, it will not enter
Neutral until the throttle is reduced below V-Start .
Note: We recommend using the brakes to stop a consist rather than
the throttle. After the consist has stopped, lowering the throttle below V-
Start
9
will ensure that all locomotives enter Neutral at the same time,
making it more likely that the consist can be reversed reliably.
6
RTC has Intrinsic Inertia; STC does not. Load value is set in Programming in POP 2 (page 19).
7
This applies to Q1a software released after July 2006. Q1 and early Q1a will require two Brake Releases.
8
If the brakes are set in Neutral, turning up the throttle automatically releases the brakes.
9
See the Analog section of your Quantum Operation Manual for an explanation of V-Start and entering and
leaving Neutral.

Quantum Engineer Operation Manual, Ver. 2.0.1 7/24 19 September 2006
Locomotive Feature Keys
Load On/Off Once you enter the Load value into Programming Option #2
(POP 2) and return to Run Mode, you can toggle this Load value on or off in
Neutral with the Load On/Off key. When Load is off, the locomotive will
accelerate or decelerate at its Intrinsic Inertia value.
Operation while in Neutral
Press the Load On/Off button once in Neutral to turn on the Load. You
will hear a Long Air Let-off.
Double-press the Load On/Off button in Neutral to turn off the Load.
You will hear a coupler clink.
Note: Labored sounds (Sound-of-Power™) are increased when Load is
on and the locomotive is accelerating.
Operation while Moving
With RTC
10
selected and the locomotive is moving in Forward or Reverse,
pressing the Load On/Off button will apply or remove a “Heavy Load” to the
locomotive. This represents a train that would take over ten to fifteen
minutes to accelerate to full speed or to coast to a complete stop. You can
apply “Heavy Load” as soon as you start moving or wait until you are up to
speed.
Press the Load On/Off button once in Forward or Reverse to turn on
Heavy Load.Hear a single Horn or Whistle hoot.
Double-press the Load On/Off button in Forward or Reverse to turn off
Heavy Load.Hear a double Horn or Whistle hoot.
Note: Heavy Load does not require you to program any Load values in
POP 2.
Note: If you apply Air Brakes while in Heavy Load, the locomotive will
return to operation using the programmed Load setting in POP 2.
Note: Be aware that once Heavy Load is turned on, the throttle will
have little effect in changing the speed of the train. If you turn the
throttle up, you will hear very intense Sound of Power effects or if you
turn the throttle down, you will hear very subdued Sound of Power
11
.
10
Load On/Off has no effect under STC.
11
If you turn the throttle down too far, the train will slow quickly as the available power to the track falls below
the level that is necessary for RTC to operate.

Quantum Engineer Operation Manual, Ver. 2.0.1 8/24 19 September 2006
You can use this feature to create heavy labored sounds while climbing
a grade or reduced labored sounds while descending a grade with very
little change in the speed of the train.
Dynamic Brakes Many prototype diesel locomotives have dynamic brakes
that cause the train to slow down by using the traction motors in generator
mode. This helps dissipate the energy of a moving train by converting it to
electrical power, which is then applied to a large air-cooled resistor load in
the locomotive.
While the locomotive is operating at a steady speed, press the
Dynamic Brakes key once to turn on the Dynamic Brakes. Hear the
Diesel Motor reduce to notch 1 followed by the sound of the powerful
diesel Cooling Fan starting up.
Double-press the Dynamic Brakes key to turn off the Dynamic Brakes.
Hear the Dynamic Brake Cooling Fan shut off while the Diesel Motor
returns to its original notch and Sound-of-Power setting.
Note: If the Dynamic Brakes key is pressed for a steam loco, the
Chuffing will reduce to a low level and return to its previous setting
when Dynamic Brakes are shut off. This makes steam locomotive
behavior similar
12
to diesels in a consist.
Note: In contrast to Air Brakes (F7), Dynamic Brakes do not increase
the deceleration rate specified by the Load setting in POP 2. The
Dynamic Brakes are only a sound effect and have no actual braking
action
13
.
Note: The Dynamic Brake function automatically turns off when
entering or leaving Neutral, or when the speed of the locomotive drops
below 7 smph
14
. The Dynamic Brakes cannot be turned on in Forward
or Reverse unless the locomotive is traveling over 8 smph. Dynamic
Brakes will not turn on if the locomotive is accelerating.
Note: Dynamic Brakes can be turned on in Neutral if the locomotive is
in Disconnect (see note under Locomotive State Keys, page 15).
12
It would be unrealistic for a steam locomotive to be working at full Sound-of-Power while Dynamic Brakes are
being applied to other locomotives within the same consist.
13
Prototype dynamic brakes are commonly used on down grades with the intention of maintaining a constant
speed rather than stopping the train.
14
Dynamic Brakes on prototype diesel locomotives are seldom used at low speeds where they are less
effective.

Quantum Engineer Operation Manual, Ver. 2.0.1 9/24 19 September 2006
Grade Crossing Prototype railroads use horn or whistle codes of long and
short blasts for communication or warning signals. One of the most common
is the code of two longs, a short and a long horn signal to warn of
approaching a grade crossing
15
. Although the Quantum operator can
perform these signals with the Horn button, we have made it even more
convenient.
Press the Grade Crossing key once to trigger the grade crossing
warning signal.
If you press the Horn key during the Grade Crossing scenario, you will
terminate this feature and take control of the Horn.
Note: Grade Crossing feature does not operate in Neutral.
Doppler You can trigger the Doppler effect by quickly interrupting the horn
signal in the same way it is described in the Analog section of your Quantum
Operation Manuals. Or you can use the Doppler Key dedicated to the
Doppler effect.
Start the Horn or Whistle by pressing the Horn key
16
and hear the
normal Horn or Whistle.
While still pressing the Horn key, press and release the Doppler key to
hear the Doppler shift. A few seconds after the Horn key is finally
released the locomotive sounds return to normal
17
.
Flanges Quantum provides automatic Squealing Brakes
18
sounds as a
locomotive slows to a stop. The operator can also control Squealing sounds
for continuous and variable brake sounds for protracted stops or to simulate
the sounds of wheel Flanges on curved track.
Pressing the Flanges key when the loco is moving at any speed will
manually activate Squealing sounds, and repeated pressings while the
Squealing sounds are occurring will continue the sounds uninterrupted.
15
Different countries use different coded signals (E.G. in Japan two longs are used for a grade crossing).
16
If you do not turn on either Horn or Bell, the Doppler shift will still occur with the locomotive sounds, but will
be less dramatic.
17
If the bell was on, it will shut off prior to all sounds returning to normal.
18
Squealing Brakes come on automatically when the speed is reduced from high-speed travel (over 40 smph)
to less than 20 smph.

Quantum Engineer Operation Manual, Ver. 2.0.1 10/24 19 September 2006
Note: Flanges are a sound effect only and will not slow the locomotive.
Coupler Sounds There are two ways to use the Coupler Sounds effect key.
As your locomotive is about to couple up to a string of cars, press the
Coupler Sounds key to trigger the Coupler Crash sound. Use the
Coupler Sounds key again as the locomotive moves out to trigger the
same sound as the slack is taken up in the cars
19
.
Coupler Sounds have a different effect in Neutral. While stopped in
Neutral in uncoupling position over an uncoupling magnet, press the
Coupler Sounds key once to produce the sound of the lift bar and
coupling pin being raised. This also Arms the uncoupling sound effect.
Press the Coupler Sounds key again while pulling away from the cars
(or remaining stationary in Neutral) to trigger the sound of the coupler
knuckle opening and air-lines parting.
Smoke Your locomotive may be equipped with an automatic Smoke Unit,
which may control the smoke differently in each of the directional states.
Press the Smoke key once to turn on the automatic Smoke Unit.
Double-press the Smoke key to turn off the automatic Smoke Unit. The
Smoke Unit will be off in all directional states.
Note: The Smoke Unit in your locomotive may be wired directly to the
power pick-ups in which case it will not be controlled by QARC
technology and pressing the Smoke button on the Quantum Engineer
will have no effect.
19
The locomotive must actually be moving in order for this effect to occur.

Quantum Engineer Operation Manual, Ver. 2.0.1 11/24 19 September 2006
Automatic Features with “Take Control” Operation
Many of the features that can be turned on or off by Quantum Engineer already
have Automatic Control. The Quantum System allows the operator to “Take
Control” of certain automatic features by using their associated control keys. Once
you “Take Control”, the features will no longer have Automatic Control and you will
control their operation and state with their key commands. Automatic and Take
Control operations are described in the table below.

Dim Headlight key will not have a noticeable effect. However, if the
Headlight is turned on at a later time, it will come on with the dim
setting set by the Dim Headlight key.

Quantum Engineer Operation Manual, Ver. 2.0.1 13/24 19 September 2006
Reverse Light ‘
Press the Reverse Light key once to turn on the Reverse Light and
Take Control of the Reverse Light. The Reverse Light will be on in all
directional states.
Double-press the Reverse Light key to turn off and take control of the
Reverse Light. The Reverse Light will be off in all directional states.
Hazard Lights Hazard Lights can be a Mars Light, Over-Head Blinking
Lights, or Ditch Lights.
Press the Hazard Lights key once to turn on and take control of the
Hazard Lights. The Hazard Lights will be on in all directional states.
Double-press the Hazard Lights key to turn off and take control of the
Hazard Lights. The Hazard Lights will be off in all directional states.
Note: Mars Light and Ditch Lights are part of the automatic lighting
system. Overhead Blinking Lights are on in all directional states.
Strobe Hazard Hazard Lights can either be steadily-on or strobing. The
Mars Light strobe gives the effect of a moving beam of light, the Over-Head
Light strobe is a steady repetitive blinking, and Ditch Lights strobe blinks
back and forth between the right and left lights.
Press the Strobe Hazard key once to turn on the strobe effect and take
control of the Hazard Lights.
Double-press the Strobe Hazard key to turn off the strobe effect and
take control of the Hazard Lights.
Note: If Hazard Lights have been turned off with the Hazard Lights
key, the Strobe Hazard key will not have a noticeable effect. However,
if the Hazard Lights are turned on at a later time, they will come on at
the strobe setting set by the Strobe Hazard key.
Cab Lights This key turns the Cab Lights on or off on specially equipped
locomotives.
Press the Cab Lights key once to turn on and take control of the Cab
Lights.

Quantum Engineer Operation Manual, Ver. 2.0.1 14/24 19 September 2006
Double press the Cab Lights key to turn off and take control of the Cab
Lights.
Blower/Fans This key turns the steam Blower or diesel Cooling Fans on
or off.
Press the Blower/Fans key once to turn on and take control of Blower
or Cooling Fans operation.
Double press the Blower/Fans key to turn off and take control of
Blower or Cooling Fans operation.
Locomotive State Keys
Disconnect/Standby Disconnect will disable the locomotive’s electric
motor drive circuit to allow the throttle to be changed without the locomotive
moving. In Disconnect, the operator can increase the throttle on a stationary
locomotive to rev the Diesel Motor or vent steam in a steam engine.
Standby places the locomotive in a special idle state with subdued sounds
where it will not respond to throttle or most of the feature keys
20
. Standby is
ideal for leaving some locomotives running on a siding while you operate
other locomotives.
Press the Disconnect/Standby key once in Neutral to enter
Disconnect.
To leave Disconnect:
Press the Start Up key to regain normal operation.
Or press the Disconnect/Standby key again to enter Standby.
Or press the Shut Down key to enter Total Shut Down.
To leave Standby:
Press the Start Up key to enter normal operation.
Or press the Shut Down key to enter Total Shut Down.
20
The four exceptions are the F6 Start Up key, the Mute Key, the Shut Down key and the Status Key.

Quantum Engineer Operation Manual, Ver. 2.0.1 15/24 19 September 2006
Note: You can turn on diesel Dynamic Brakes in Disconnect to create
Sound–of-Power as the throttle is moved up and down. Engineers on
prototype diesels use the dynamic brakes to load the diesel motor-
generator to test its output and efficiency while the locomotive remains
stationary.
Note: If power is turned off during either the Disconnect or Standby
procedures, the locomotive will remember the last command and will
power up in the same stage. If Start Up is initiated during any of the
above procedures, the locomotive will immediately return to normal
operation.
Note: Neither the Horn nor the Bell key will operate in Standby or Shut
Down. Analog Programming is disabled in Disconnect and Standby.
Shut Down Shut Down allows the operator to take the locomotive “off line”
(turn off sounds, lights, ignore throttle settings and feature commands
21
)
independent of the operating session; that is, the locomotive will still be “off
line” when power is reapplied for the next operating session.
Press the Shut Down key once to produce a Rapid Shut Down. Rapid
Shut Down will shut the locomotive off in a few seconds.
Double press the Shut Down key to produce an Extended Shut Down
scenario. Extended Shut Down will shut the locomotive down over thirty
seconds with progressive sound and light effects. The Extended Shut
Down for diesels and steam are as follows:
Diesel Extended Shut Down: After double pressing the Shut Down
key, hear a Long Air Let-off, followed by Directional Lighting turning off
(if on). In a few seconds, the Air Pumps shut off, followed by the
Number Boards and the sounds of the Cooling Fans shutting off, the
louvers closing, the Diesel Motor shutting down and finally, the Cab
Lights shutting off. After a short time, you will hear the engineer’s door
open and then shut.
Steam Extended Shut Down: After double pressing the Shut Down
key, you will hear a Long Air Let-off, followed by Directional lighting
turning off (if on). In a few seconds, the Air Pumps will turn off, followed
by the sounds of Pop Off operating for about ten seconds followed by a
hiss sound that gradually trails off to silence.
21
The two exceptions are the Start Up Key and the Status Key.

Quantum Engineer Operation Manual, Ver. 2.0.1 16/24 19 September 2006
To leave the Shut Down state, press the Start Up key.
Note: If power is turned off during a Shut Down procedure, the
locomotive will be in Shut Down when power is reapplied. If the Start
Up key is pressed during a Shut Down procedure, Shut Down is
aborted and the locomotive returns to normal operation.
Note: Except for a few extra sound effects for Extended Shut Down,
the shutting down of lighting and sound effects still occur during Rapid
Shut Down but happen more quickly.
Note: You cannot shut down a locomotive while it is moving. There is
no response if you press the Shut Down key in Forward or Reverse.
Note: All locomotives on the same powered track will go into Shut
Down when you press the Shut Down key.
Start Up If your locomotive is in Disconnect, Standby or Shut Down, you
can return your locomotive to normal operation by pressing the Start Up
key.
Start Up will be different for each stage of Shut Down, but all will start up
with a Long Air Let-off and will enter normal operation.
Start Up from Disconnect: Press the Start Up key in Disconnect and
the locomotive will produce a Long Air Let-off then enter normal
operation.
Start Up from Standby: If you double press the Start Up key in
Standby, the locomotive will produce a Long Air Let-off, the Directional
Lighting will turn on and then the locomotive will enter normal
operation.
Start Up from Shut Down:
Press the Start Up key once to produce Rapid Start Up.
Double press the Start Up key to produce an Extended Start
Up scenario. The Extended Start Up for diesels and steam are
as follows:
Diesel Extended Start Up: If you double press the Start Up key, the
diesel locomotive will produce a Long Air Let-off. After a few seconds,
you will hear the engineer’s door opening and closing, followed by
lighting turning on, vents opening, the Diesel Motor starting up, the Air
Pumps starting up, and the locomotive entering normal operation.

Quantum Engineer Operation Manual, Ver. 2.0.1 17/24 19 September 2006
Steam Extended Start Up: If you double press the Start Up key in
Shut Down, the steam locomotive will produce a Long Air Let-off, the
Dynamo will rev up and the Directional Lighting will turn on, followed by
the Air Pumps starting up, the steam Blower turning on, the Cylinder
Cocks arming, and then the locomotive will enter normal operation.
Note: Whenever a Start Up command is sent to a selected locomotive,
regardless of whether the locomotive is in Shut Down or operating normally,
the Quantum System will automatically restore all Automatic Controls and
re-arm Steam Cylinder Cocks on steam locomotives.
Status Report Quantum provides verbal information about the locomotive’s
current operating state when the locomotive is stopped or the locomotive’s
current speed in scale miles per hour when moving.
Press the Status key when locomotive is stopped in Neutral. If the
locomotive is in Disconnect /Standby /Shut Down it will say so.
Otherwise the locomotive’s Helper type (if not Normal) will be
announced, followed by Load level, Load on/off status (if Load not
equal to zero), and type of Throttle Mode (Regulated or Standard).
Press the Status key while locomotive is moving. The locomotive will
verbally report its speed in scale miles per hour.
Note: When Status Report is activated, the locomotive’s sounds will
reduce to one half their current volume settings during the verbal report
and then return to normal volume when the report has ended.
Star Pad Keys During Normal Operation
Volume and
Volume Locomotive System Volume can be changed
22
anytime the
locomotive is operating (except in Shut Down).
Press the Volumekey to increase the System Volume level.
Press the Volumekey to decrease the System Volume level.
22
If your locomotive is equipped with Magnetic Wand option, the System Volume can also be increased or
decreased, using the wand, in any state. See your Quantum Operation Manual.

Quantum Engineer Operation Manual, Ver. 2.0.1 18/24 19 September 2006
Each time either Volume key is pressed and released, the volume changes
by 2 db. Or press and hold either Volume key to automatically step up or
down through the volume levels one by one; release the key when the
desired volume is reached.
Note: System Volume cannot be changed while a locomotive is in Shut
Down.
Mute The Quantum System allows you to reduce the System Volume to a
lower level or increase it back to its original setting using the Mute key. This
is useful when you need to lower the sound to engage in a conversation or
to answer the phone. The Mute feature changes the sound volume gradually
over a second or two
23
.
Press the Mute key once to gradually reduce the volume to the Mute
level.
Double press the Mute key to gradually restore the locomotive sounds
to its normal level.
Note: Mute state is not maintained if power is turned off and back on;
the locomotive will return to full System Volume setting.
STC and
RTC Use these keys in Neutral to select Throttle Mode. Quantum has two
types of throttle control as described in the Quantum Operation Manuals
that came with your locomotive. Regulated Throttle Control (RTC) has motor
control capability that allows the locomotive to behave as though it has
massive inertia. Engines under Standard Throttle Control (STC) respond
quickly to changes in throttle or loading. The default is RTC.
Press the STC key to select Standard Throttle Control.
Press the RTC key to select Regulated Throttle Control.
Regulated Throttle is preferred under normal operation. However, STC is
preferred when putting locomotives away or when uncoupling.
23
Mute can be useful during operation by lowering the volume realistically as the locomotive moves to the
background of the layout and increasing the volume realistically as the locomotive moves to the foreground.

Quantum Engineer Operation Manual, Ver. 2.0.1 19/24 19 September 2006
Programming with Star Pad Keys
The Quantum Engineer Controller makes Analog programming of your Quantum
locomotive with QARC technology very simple. All programming is done using the
Star Pad keys. Programming Mode functions are shown in gray italics while Run
Mode functions are shown in normal type.
Entering Program Mode
Prgm Press and hold the Prgm key prior to turning up the throttle to where
the locomotive sounds come on. Continue to hold the Prgm button until you
hear “Enter Programming”. The locomotive will then respond with “Option
One –System Volume”.
Note: You cannot use the Prgm key to enter Programming Mode on
earlier Quantum locomotives that do not have QARC technology.
Note: Once you have entered Programming Mode, the Prgm key has
no effect.
Note: When in Programming Mode, the red power light on the
Quantum Engineer blinks on and off.
Note: In Programming Mode, the locomotive’s Directional Lighting
alternately blinks between the Headlight and the Reverse Light.
Scrolling through the Program Options
Next and
Prev Use the Next and Prev keys on the Star Pad to move easily through the
Program Options (POP’s). The Program Option numbers and names are

Press the Prev key once to move to the previous POP. The locomotive
will announce the previous POP number and name. Or press and hold
the Prev key to automatically step backwards through the POP’s one
by one and then release the key when the desired POP is reached.

Entering a Program Option and Making Changes
Volume and
Volume The Up Volume and Down Volume level keys can be used to
enter and change POP values.
Press either the Volumeor Volumekey once to enter the
POP. Entering a POP does not make any changes. The locomotive will
announce the current setting for that option. For any volume option,
hear “Volume equals X” (where “X” is its current volume level setting).
After a moment, you will hear the sound playing at its current volume

After the announcement of the current value, press the Volumeor
the Volumekey to increase or decrease the option setting by one
level. Or press and hold the Volumeor Volumekey to
automatically step up or down through the level settings one by one
and then release the key when the desired level is reached.
Note: Most POP’s require an increase or decrease in some level
setting. For instance, many POP’s are used to increase or decrease
volume levels of the different sound effects while POP 2 is used to
increase or decrease the Load setting.
For volume settings, Volumewill increase the volume level and
Volumewill decrease the volume level. Volume will change by 2 db
for each level change. These two buttons also increase or decrease the
Load level in POP 2. For POP’s with level settings, you will hear the level
value spoken out.
