Main Features

Welcome to the Loop Station!

The RC-300 is a pedal-type recorder that lets you record audio phrases from your guitar or vocal etc., and play them back by operating the pedal.
You can create a wide variety of performances by layering sound while you record and carry out play back in real time.

• You can save a maximum of approximately 3 hours of stereo sound (*total for all phrase memory) and up to 99 phrase memories.

• Three-track recording allows a wide range of performance possibilities.

• You can input audio in stereo.

• In addition to guitar (INST) input, a MIC input and AUX IN jacks are also provided. You can connect a microphone and loop-record your voice, or
record sound from your digital audio player.

• You can easily connect the RC-300 to your computer using a single USB cable. Once connected, you gain a digital audio connection with your
computer and the ability to export/import loop phrases (WAV les) (p. 36).

• You can apply an eect that is synchronized with the tempo of tracks while you play it back. You can use the EXP (expression) pedal to control
eects (p. 28).

• Two RC-300 units can be synchronized after connecting them together using a MIDI cable (p. 39).

Turning On the Power

Once the connections have been completed, turn on power to your various devices in the order specied. By turning on devices in the wrong order,
you risk causing malfunction and/or damage to speakers and other devices.

When powering up Turn on the power to your amp last.

When powering down Turn o the power to your amp rst.

1. Turn the [POWER] switch ON.

* This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required before the unit will operate normally.

Also, for a short period of time, phantom power won’t be switched on for the INPUT MIC connector.

* Before switching the power on/o, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound

when switching the power on/o. However, this is normal and does not indicate a malfunction.

Caution when turning o the power

While the RC-300 is in the following states, you must never turn o the power. Doing so may cause all the saved data to be lost.

• While recording/overdubbing/playing back

• While undoing/redoing

• While switching between phrase memories

• While the following messages are displayed

“Now work ing..”, “Now writing...”, “Now copying..”, “Exchanging..”, “Initializing...”

Basic Operation Saving Track

Phrase Memory

Rhythm LOOP FX System Settings USB MIDI AppendixOverview

Caution when connecting

* To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn o the power on all devices before

making any connections.

* Before connecting or disconnecting any connection cables, be sure all the volume controls in your system are set to minimum.

* When connection cables with resistors are used, the volume level of equipment connected to the inputs (AUX/INST/MIC jacks) may be low. If this

happens, use connection cables that do not contain resistors.

Caution when using a microphone

* Howling could be produced depending on the location of microphones relative to speakers. This can be remedied by:

• Changing the orientation of the microphone(s).

• Relocating microphone(s) at a greater distance from speakers.

• Lowering volume levels.

* If the amp and microphone are close together, the sound played back from the amp may be picked up by the microphone. If you record or overdub

in such a state, the amp playback picked up by the microphone will also be recorded. You should separate the amp and microphone so that the
playback from the amp is not picked up by the microphone.

* Always turn the phantom power o when connecting any device other than condenser microphones that require phantom power. You risk causing

damage if you mistakenly supply phantom power to dynamic microphones, audio playback devices, or other devices that don’t require such power.
Be sure to check the specications of any microphone you intend to use by referring to the manual that came with it.
(This instrument’s phantom power: 48 V DC, 10 mA Max)

* This instrument is equipped with balanced (XLR) type jacks. Wiring diagrams for these jacks are shown below. Make connections

after rst checking the wiring diagrams of other equipment you intend to connect.

Rhythm

System Settings

LOOP FX

What are tracks (p. 16) and phrase memories (p. 20)?

The RC-300 provides three “tracks” that are used to record and play back the sound of an instrument or microphone.

These three tracks combined form what is called a “phrase memory.” Up to 99 phrase memories can be stored.

What is a rhythm? (p. 25)

In addition to the three tracks, the RC-300 can also play a “rhythm.” You can record while listening to a rhythm at the tempo you
specify.

What is the LOOP FX? (p. 28)

You can apply an eect to the sound of each track. This eect is called a “LOOP FX.”

What are system settings? (p. 32)

Settings that apply to the entire RC-300, such as those for the contrast of the display and the auto o function, are called “system
settings.”

Saving your data (p. 14)

If you select a dierent phrase memory or turn o the power after recording or editing the settings, the recorded content or edited settings will
be lost. If you want to preserve a phrase memory, you must save it as described in “Saving a Phrase Memory (Write)” (p. 14).

However, system settings are saved as soon as you edit them.

• When shipped from the factory, phrase memories 90–99 contain demo
data.

“Recording” versus “Overdubbing”

In this manual, we refer to the act of recording to an empty track for the rst time as “recording.” Any subsequent recordings that are made,
which are added on top of the existing recording, we refer to as “overdubbing.”

Using the pedals to select phrase memories or LOOP FX (Pedal Function mode)

Hold down the [LOOP FX] pedal for two seconds or longer to put the RC-300 in Pedal Function mode; now you can use the TRACK 1 pedals to
select phrase memories, and the TRACK 3 pedals to select the LOOP FX.

NOTE

* The minimum recording time for a track is approximately 1.5 seconds. If you press the pedal within approximately 1.5 seconds after you start

recording, recording will continue until the track is at least approximately 1.5 seconds long.

* The maximum recording time is approximately 3 hours (total for all phrase memories). When the maximum recording time is exceeded, the

display will show “Memory Full!” to indicate that internal memory is full, and recording or overdubbing may end before you intended. If this
occurs, delete unneeded phrase memories (p. 15) and then try the operation again.

the same backing, as it allows you to prepare tracks simply and
easily without having to start recording from scratch again.

1. To prevent loss of the content of the current work, press

the [WRITE] button twice to save the current phrase
memory.

Since you need to conrm the sound of the current source track,
you must select the copy-source phrase memory once in Track

Overview of the Playback Settings

The RC-300 lets you specify the playback method independently for
each track.

Loop Playback Settings (Play Mode)

For each track, you can specify either loop playback or one-shot
(i.e., not looped).

If one-shot playback is selected, playback will stop when
it reaches the end of the phrase (it will not loop).

Loop

Reference

Refer to the track setting “Play Mode” (p. 17).

If you turn Loop Sync on for two or more tracks, loop playback of
those tracks will be synchronized at the beginning of the longest
phrase with Tempo Sync on among these tracks.

For tracks whose Loop Sync is
o, playback will repeat at the
length of the phrase.

Synchronizing the Tempo (Tempo Sync)

Each track saves the tempo at which that track was recorded. This
is called the “original tempo” (p. 19) of the track. The phrase
memory also has a “phrase memory tempo” (p. 21) that is
shared by all tracks 1, 2, and 3.

Normally, you should leave Tempo Sync on, so all tracks will play
at the same tempo (the phrase memory tempo). If you turn Tempo
Sync o for tracks for which you don’t want the tempo to change
(such as those with special eects), you’ll be able to obtain playback
that is always at the original tempo.

Tracks for which Tempo Sync is on will
play at the phrase memory tempo.

If you turn Loop Sync on, the beginning of the tracks will always

playback start location of the other tracks will become “the current
location of the phrase being played.” The following illustration is an
example of how playback will occur with three tracks that contain
the identical melody but have dierent loop sync settings.

For a track with Loop Sync on,
playback starts midway through the

• If the rhythm is on

• If there is an already-recorded track whose Tempo Sync is turned on or Loop

This function will automatically adjust the length of the phrase to match
the tempo and the time signature of the rhythm, even if the timing at which
recording ended was not quite accurate.

Recorded phrase

For a track with Loop Sync o,
playback always starts at the
beginning of the phrase.

Even if the timing is slightly
inaccurate, the phrase
length will automatically
be adjusted to the precise
measure interval.

You can specify the number of measures for each track. When
recording rhythm sounds or when recording along with other
tracks, it’s convenient to specify the number of measures before you
record, so that looping will occur at the specied measure length,
even if you don’t operate the pedal when you’ve nished recording.

Specifying the Number of Measures in a Track (Measure)

You can specify the number of measures for each track. When recording rhythm sounds or when recording along

Tracks that are set to AUTO will have the same number of measures. The number of
measures is determined by the rst-recorded track of the tracks that are set to AUTO. For
example, if all tracks are set to AUTO, the value set as the number of measures for the
second and subsequent tracks will be identical to the number of measures in the rst track
that was recorded.

The number of measures will be set automatically, corresponding to the length of the recording.

Specifying How the Track Will Stop (Stop Mode)

This species how the track will stop when you press the [STOP] pedal.

• The PLAY indicator will blink until playback stops.

• If you press the [STOP] pedal once again before playback stops, playback will stop immediately.

* You can’t overdub during the time until playback stops.

Phrase Memory

About original tempo

Each track saves the tempo at which that track was recorded. This is called the “original tempo” of the track. The phrase memory also has a
“phrase memory tempo” (p. 21) that is shared by all tracks 1, 2, and 3.

When recording ends, the original tempo is automatically calculated according to the following conditions.

Condition Original tempo value to be saved

Rhythm is playing

Other tracks have phrases with the following settings

• Play Mode at LOOP, Loop Sync ON

• Play Mode at LOOP, Tempo Sync ON

Cases other than the above

Original tempo will be set from the “phrase memory tempo” (p. 21).

The original tempo is automatically calculated according to the following conditions.

Phrase Memory Tempo will be set to the same value as the automatically calculated original tempo.

The original tempo is calculated according to the rhythm’s time signature (Beat: p. 25) and the number of
measures (Measure).

For example, if the time signature (Beat) is “4/4,” the number of measures (Measure)
is “4,” and you’ve recorded for six seconds, the calculated tempo will be “160.”

4/4 time signature

If the number of measures (Measure) is set to “2,” the calculated tempo will be “80.”

4/4 time signature

The recorded number of measures is assumed to be “1, 2, 4, 8, 16... measures,” and the original tempo
will be calculated in the range of “80–160.”

Specifying the Type of Operation (Source Mode)

If a momentary-type foot switch (such as the separately sold FS-5U) is connected as the source, you can specify how
foot switch operations will aect the value.

* If the [LOOP FX] pedal is set to MOMENT, it will no longer be possible to enter Pedal Function mode (p. 10) by

holding down the [LOOP FX] pedal for two seconds or longer.

MOMENT

TOGGLE

The setting will normally be o (minimum value); it will be on (maximum value) only while
you continue holding down the foot switch.

The setting will alternate between o (minimum value) and on (maximum value) each time
you press the foot switch.

Connecting to External Pedals

Connect your EXP pedals (EV-5, etc. ; available separately) or foot switches (FS-5U, FS-6; available separately) as shown in the illustration.

The function of the external pedal (EXP pedal or foot switch) can be assigned independently for each phrase memory. For details, refer to “Assigning
the Function of Pedals and External Controllers (Assign)” (p. 23).

Overview Basic Operation Saving Track

Phrase Memory

Rhythm LOOP FX System Settings MIDI AppendixUSB

About the original tempo of WAV les imported from a computer

• The original tempo (p. 19) and the number of measures in the track (Measure: p. 17) of an imported WAV le are specied by calculation
based on the selected rhythm’s time signature (Beat: p. 25).

• If you’re importing a WAV le that has a time signature other
than 4/4, you should rst specify the rhythm’s time signature
(Beat: p. 25) for that phrase memory and then save the phrase
memory before importing the le.

• The RC-300 will assume that you’ve recorded “1, 2, 4, 8, 16...
measures,” and will calculate the tempo within the range of
“80–160.”
This means that when you import a WAV le from your
computer, the original tempo might be specied as double or
half the true tempo. In this case, you can change the original
tempo to the correct value by specifying the number of
measures (Measure: p. 17).

When you import a WAV le with “tempo: 70 (number of measures: 2)” from
your computer, “140” will be set as the original tempo (in order to keep the
tempo within the range of 80–160).

In the case of 2 measures…Tempo: 70

In the case of 4 measures…Tempo: 140

In the case of 8 measures…Tempo: 280

In this case, you can correct the original tempo to “70” by changing the
number of measures (Measure: p. 17) from “4” to “2.”

Connecting an External MIDI Device or Another RC-300 Unit

What is MIDI?

MIDI (Musical Instrument Digital Interface) is a standard specication that allows musical data to be transferred between electronic musical
instruments and computers. If a MIDI cable is connected between devices equipped with MIDI connectors, you’ll be able to play multiple
devices from a single MIDI keyboard, perform ensembles using multiple MIDI instruments, program the settings to change automatically as the
song progresses, and more.

About MIDI Connectors

The following types of connector are used to convey MIDI messages. MIDI cables are connected to these connectors as needed.

Connector Explanation

MIDI IN This connector receives messages from another MIDI device.

MIDI OUT This connector transmits messages from this device.

MIDI THRU

MIDI settings

This connector re-transmits the messages that were received at
MIDI IN.

For details on the RC-300’s various MIDI parameters, refer to the following pages.

Settings Page

System Settings “MIDI-Related Settings” (p. 34)

Settings for each phrase memory

* Use of MIDI requires that the MIDI channels be matched with those of the connected device. Data cannot be transmitted to, nor received from

another MIDI device unless the MIDI channels are set properly.

Controlling an External MIDI Device from the RC-300

Operation Over View Explanation

Playing Performances on External MIDI Devices at the Same Tempo as the RC-300’s Tempo

MIDI clock messages are output from the RC-300 at all times. Set the external MIDI device
beforehand so it is ready to receive MIDI Clock and MIDI Start and Stop messages. For details,
refer to the owner’s manual that came with the device.

Transmitting Start/Stop

A MIDI Start message is transmitted at the moment that recording or playback of the track
begins, when all tracks had been stopped. This message is also transmitted when an All Start is
carried out.

A MIDI Stop message is transmitted when all of the tracks have stopped. This is also transmitted
when All Stop is in eect.

Transmitting Program Changes

When phrase memories are switched on the RC-300, a MIDI Program Change message is
transmitted to the connected external MIDI device. You can transmit Program Change messages
numbered 1 through 99,corresponding to the 99 individual phrase memories 1–99.

* Set “MIDI Program Change Out” (p. 34) to ON beforehand.

* Program Change messages 100–128 cannot be transmitted.

* Bank Select MIDI messages (Control Change #0, #32) cannot be transmitted.

Transmit a control change

By selecting a control change as the Assign Target (p. 23), you can use the RC-300’s [EXP 1] pedal,
or an external EXP pedal or external foot switch (connected to the CTL 1, 2/EXP 2 jack or CTL 3,
4/EXP 3 jack) to transmit MIDI control change messages.

The RC-300’s performance tempo data is
transmitted to external MIDI devices as MIDI
clock.

Playback start and stop operations with the
RC-300’s pedals can be transmitted as MIDI
Start and Stop messages.

When a phrase memory is selected with the
RC-300, a Program Change message cor­responding to the selected phrase memory
number is transmitted simultaneously.

An ongoing description of all operations you
perform using the EXP pedal or externally
connected foot switch can be output in
the form of data called Control Change
messages. These messages can be used for
various purposes, such as controlling the
parameters of an external MIDI device.

Connecting Two RC-300 Units

Two RC-300 units can be synchronized after connecting them together using a MIDI cable.

• Use a commercially available MIDI cable to make the following connection.

MIDI OUT connector MIDI IN connector

RC-300 (Master unit) RC-300 (Slave unit)

• Set the “MIDI Sync” parameter described in “Synchronizing the Tempo of Two RC-300 Units (MIDI Sync)” (p. 34) to “INTERNAL” for the master RC-300
unit and to “MIDI” for the slave RC-300 unit.

• Begin recording on the master RC-300 unit’s tracks.

• When you press the master RC-300 unit’s [ALL START/STOP] pedal, the slave RC-300 unit will also play/stop.

• Tracks for which Tempo Sync is on will play at the phrase memory tempo (p. 21) of the master unit.

• Tracks for which Loop Sync (p. 18) is on will loop in synchronization with the longest phrase on the master RC-300 unit.

* Do not change the phrase memory tempo of the master unit during a synchronized performance using two RC-300 units. It is not possible to

change the phrase memory tempo of the slave unit (the unit whose MIDI Sync setting is “MIDI”).

to domestic animals or pets.

WARNING

Do not open (or modify in any way) the unit or
its AC adaptor.

Do not attempt to repair the unit, or replace
parts within it (except when this manual
provides specic instructions directing you to
do so). Refer all servicing to your retailer, the
nearest Roland Service Center, or an authorized
Roland distributor, as listed on the “Information”
page.

Never install the unit in any of the following
locations.

• Subject to temperature extremes (e.g.,
direct sunlight in an enclosed vehicle,
near a heating duct, on top of heat­generating equipment); or are

• Damp (e.g., baths, washrooms, on wet
oors); or are

• Exposed to steam or smoke; or are

• Subject to salt exposure; or are

• Humid; or are

• Exposed to rain; or are

• Dusty or sandy; or are

• Subject to high levels of vibration and
shakiness.

Make sure you always have the unit placed so
it is level and sure to remain stable. Never place
it on stands that could wobble, or on inclined
surfaces

Be sure to use only the AC adaptor supplied
with the unit. Also, make sure the line voltage
at the installation matches the input voltage
specied on the AC adaptor’s body. Other AC
adaptors may use a dierent polarity, or be
designed for a dierent voltage, so their use
could result in damage, malfunction, or electric
shock.

Do not excessively twist or bend the power
cord, nor place heavy objects on it. Doing
so can damage the cord, producing severed
elements and short circuits. Damaged cords are
re and shock hazards!

This unit, either alone or in combination with an
amplier and headphones or speakers, may be
capable of producing sound levels that could
cause permanent hearing loss. Do not operate
for a long period of time at a high volume
level, or at a level that is uncomfortable. If you
experience any hearing loss or ringing in the
ears, you should immediately stop using the

• Objects have fallen into, or liquid has
been spilled onto the unit; or

• The unit has been exposed to rain (or
otherwise has become wet); or

• The unit does not appear to operate
normally or exhibits a marked change in
performance.

In households with small children, an adult
should provide supervision until the child is
capable of following all the rules essential for
the safe operation of the unit.

Protect the unit from strong impact.

(Do not drop it!)

Do not force the unit’s power-supply cord to
share an outlet with an unreasonable number
of other devices. Be especially careful when
using extension cords—the total power used by
all devices you have connected to the extension
cord’s outlet must never exceed the power
rating (watts/amperes) for the extension cord.
Excessive loads can cause the insulation on the
cord to heat up and eventually melt through.

Before using the unit in a foreign country,
consult with your retailer, the nearest Roland
Service Center, or an authorized Roland
distributor, as listed on the “Information” page.

CAUTION

The unit and the AC adaptor should be located
so their location or position does not interfere
with their proper ventilation.

Always grasp only the output plug or the body
of the AC adaptor when plugging into, or
unplugging from, this unit or an outlet.

CAUTION

At regular intervals, you should unplug the AC
adaptor and clean it by using a dry cloth to
wipe all dust and other accumulations away
from its prongs. Also, disconnect the power
plug from the power outlet whenever the unit
is to remain unused for an extended period of
time. Any accumulation of dust between the
power plug and the power outlet can result in
poor insulation and lead to re.

Try to prevent cords and cables from becoming
entangled. Also, all cords and cables should be
placed so they are out of the reach of children.

Never climb on top of, nor place heavy objects
on the unit.

Never handle the AC adaptor body, or its
output plugs, with wet hands when plugging
into, or unplugging from, an outlet or this unit.

Before moving the unit, disconnect the AC
adaptor and all cords coming from external
devices.

Before cleaning the unit, turn o the power and
unplug the AC adaptor from the outlet (p. 7).

Whenever you suspect the possibility of
lightning in your area, disconnect the AC
adaptor from the outlet.

To prevent accidental ingestion of the parts
listed below, always keep them out of the reach
of small children.

• Removable Parts
USB cap (p. 6)

Always turn the phantom power o when
connecting any device other than condenser
microphones that require phantom power. You
risk causing damage if you mistakenly supply
phantom power to dynamic microphones,
audio playback devices, or other devices that
don’t require such power. Be sure to check the
specications of any microphone you intend
to use by referring to the manual that came
with it.

(This instrument’s phantom power: 48 V DC, 10
mA Max)

IMPORTANT NOTES

Power Supply

• Please don’t touch the mains plug pins soon
after removing the adaptor from the outlet.

• Do not connect this unit to same electrical outlet
that is being used by an electrical appliance
that is controlled by an inverter (such as a
refrigerator, washing machine, microwave oven,
or air conditioner), or that contains a motor.
Depending on the way in which the electrical
appliance is used, power supply noise may cause
this unit to malfunction or may produce audible
noise. If it is not practical to use a separate
electrical outlet, connect a power supply noise
lter between this unit and the electrical outlet.

• The AC adaptor will begin to generate heat after
long hours of consecutive use. This is normal,
and is not a cause for concern.

• Before connecting this unit to other devices, turn
o the power to all units. This will help prevent
malfunctions and/or damage to speakers or
other devices.

Placement

• Using the unit near power ampliers (or other
equipment containing large power transformers)
may induce hum. To alleviate the problem,
change the orientation of this unit; or move it
farther away from the source of interference.

• This device may interfere with radio and
television reception. Do not use this device in
the vicinity of such receivers.

• Noise may be produced if wireless
communications devices, such as cell phones,
are operated in the vicinity of this unit. Such
noise could occur when receiving or initiating a
call, or while conversing. Should you experience
such problems, you should relocate such
wireless devices so they are at a greater distance
from this unit, or switch them o.

• Do not expose the unit to direct sunlight, place
it near devices that radiate heat, leave it inside
an enclosed vehicle, or otherwise subject it
to temperature extremes. Excessive heat can
deform or discolor the unit.

• When moved from one location to another
where the temperature and/or humidity is very
dierent, water droplets (condensation) may
form inside the unit. Damage or malfunction
may result if you attempt to use the unit in this
condition. Therefore, before using the unit, you
must allow it to stand for several hours, until the
condensation has completely evaporated.

• Depending on the material and temperature
of the surface on which you place the unit, its
rubber feet may discolor or mar the surface.
You can place a piece of felt or cloth under the
rubber feet to prevent this from happening. If
you do so, please make sure that the unit will not
slip or move accidentally.

• Do not put anything that contains water on
this unit. Also, avoid the use of insecticides,
perfumes, alcohol, nail polish, spray cans, etc.,
near the unit. Swiftly wipe away any liquid that
spills on the unit using a dry, soft cloth.

Maintenance

• For everyday cleaning wipe the unit with a
soft, dry cloth or one that has been slightly
dampened with water. To remove stubborn
dirt, use a cloth impregnated with a mild, non­abrasive detergent. Afterwards, be sure to wipe
the unit thoroughly with a soft, dry cloth.

• Never use benzine, thinners, alcohol or
solvents of any kind, to avoid the possibility of
discoloration and/or deformation.

Repairs and Data

• Please be aware that the contents of memory
can be irretrievably lost as a result of a
malfunction or improper operation of the unit.
You should back up important data as described
in “Backing up to your computer” (p. 37).

• All due care is taken during repairs to avoid the
loss of data. However, in certain cases, such as
when there is damage to the memory, it may not
be possible to restore the data.

• Unfortunately, it may be impossible to restore
the contents of data that was stored in the
unit’s memory once it has been lost. Roland
Corporation assumes no liability concerning
such loss of data.

Copyright

• Recording, duplication, distribution, sale, lease,
performance, or broadcast of copyrighted material
(musical works, visual works, broadcasts, live
performances, etc.) belonging to a third party in
part or in whole without the permission of the
copyright owner is forbidden by law.

• Do not use this product for purposes that could
infringe on a copyright held by a third party. We
assume no responsibility whatsoever with regard to
any infringements of third-party copyrights arising
through your use of this product.

• The copyright of content in this product (the
sound waveform data, style data, accompaniment
patterns, phrase data, audio loops and image data)
is reserved by Roland Corporation.

• Purchasers of this product are permitted to utilize
said content for the creating, performing, recording
and distributing original musical works.

• Purchasers of this product are NOT permitted to

grasp the connector itself—never pull on the
cable. This way you will avoid causing shorts, or
damage to the cable’s internal elements.

• To avoid disturbing your neighbors, try to keep
the unit’s volume at reasonable levels. You may
prefer to use headphones, so you do not need to
be concerned about those around you.

• When you need to transport the unit, package
it in the box (including padding) that it came
in, if possible. Otherwise, you will need to use
equivalent packaging materials.

• Use only the specied expression pedal (Roland
EV-5, etc. ; sold separately). By connecting
any other expression pedals, you risk causing
malfunction and/or damage to the unit.

• Some connection cables contain resistors. Do
not use cables that incorporate resistors for
connecting to this unit. The use of such cables
can cause the sound level to be extremely low,
or impossible to hear. For information on cable
specications, contact the manufacturer of the
cable.

• When you operate the expression pedal, please
be careful not to get your ngers pinched
between the movable part and the panel. In
households with small children, an adult should
provide supervision until the child is capable
of following all the rules essential for the safe
operation of the unit.

• The explanations in this manual include
illustrations that depict what should typically be
shown by the display. Note, however, that your
unit may incorporate a newer, enhanced version
of the system (e.g., includes newer sounds), so
what you actually see in the display may not
always match what appears in the manual.
