Doing so may melt the insulation, impair the safety mechanism,
or ignite the electrolyte, causing ignition or explosion.
• Do not peel off or damage the external covering.
Peeling off the external covering, piercing it with a nail or sharp
object, striking it with a hammer, or stepping on it may cause a
short-circuit within the battery, causing ignition, explosion,
leakage or ejection of the electrolyte, or overheating.
• Insert the battery as instructed.
Always make sure the battery is inserted in conformity with the
+/- polarity markings. Failure to do so might cause abnormal
electric current flow in the battery, resulting in fire, explosion,
leakage or ejection of the electrolyte, or overheating in use.
• Be sure to use the specified battery.
Do not replace the battery with any battery other than the one
specified (the same type or equivalent). Otherwise, the battery
may ignite or explode, the battery liquid may spout or leak, or the
unit may heat up.
• Do not leave the battery within reach of children.
A child may swallow the battery accidentally. Also, leaking
battery liquid may cause chemical reaction or inflammation. If a
child swallows the battery accidentally, consult a doctor
immediately.
CAUTION
• Do not remove the battery while the device is in use.
Do not remove the battery while the device is being used. Doing
so could corrupt the data or cause malfunctions.
• Check the battery capacity before recording or deleting

The recorder offers five Playlist files (P1–5).
You can play your favorite songs in your
preferred order by creating Playlists using
the files stored in the MUSIC folder.
RECYCLE ( ):
This is the Recycle Bin folder.
DATA:
This folder stores data files. You can use the
recorder as a flash drive. (The folder name
will not be displayed on the recorder’s LCD.
This folder will be recognized only by a con-
nected computer.)
MANUAL:
This folder stores the Owner’s Manual and
Reference Manual in PDF format. These man-
ual files are organized in sub-folders by lan-
guage. (The folder name will not be displayed

cards formatted by other devices, such as a
computer.
Be sure to format the card using the recorder
(See page 26, PDF reference manual).
To remove the card, open the slot cover and
push in the card gently. The card will be
ejected slightly. Pull out the card carefully.
About microSD cards
If you plan to use a microSD card, choose a
1GB – 2GB microSD card, or a 4GB – 16GB
microSDHC card (these cards are compatible
as of October 2009). However, some cards
(depending on the manufacturer or type of
card) may not work with the recorder.
For more information about microSD cards,
please visit the following Yamaha website:
http://www.yamahasynth.com/
Before using the microSD card
• Make sure that you insert the microSD card in the
recorder correctly. Otherwise, the recorder will not
record to or play from the microSD card.
• Do not apply too much force when you insert or
remove the microSD card. Otherwise, you might
injure your hand or finger or damage the card.
• If you insert the microSD card in the wrong orienta-
tion or upside down, the microSD card and/or the
card slot may be damaged.
• If the recorder does not recognize the installed
microSD card when the power to the unit is turned
on, first turn off the power, remove the card, insert
the card correctly, then turn the power on.
• Do not install or remove the microSD card while the
power to the unit is on. Otherwise, the data on the
microSD card may be damaged.
• Do not touch the terminal on the microSD card or
expose the card to water or dirt.
• Do not try to bend, fold or place a heavy object on
the microSD card.
• Do not use or keep the microSD card in a location
subject to static electricity or electric noise.
• Do not place the microSD card in the vicinity of cor-
rosive chemicals or corrosive gas.
• Otherwise, the card may malfunction or data on the
card may be lost.
• Never place the microSD card within reach of small
children. A child may swallow the card accidentally.
• If you discard the microSD card without precau-
tions, important or personal data that remains on
the card may become accessible to unauthorized
individuals. To avoid this risk, erase all data on the
card, destroy the card physically, then discard it.

Introduction
Recording tips
The recorder enables you to record audio at a superior level of quality by setting the Recording
mode, ALC (Auto Level Control) function, microphone sensitivity, recording peak limiter and
other functions. Please refer to the Reference Manual (PDF file) for information on the other
functions.
■ Recording mode
The recorder records audio in the MP3 or PCM (WAV) format. As a rule of thumb, select “PCM
44.1kHz/16 bit” (better sound quality) for the Recording mode to record a musical perfor-
mance. Select “MP3 128kbps” (smaller data size) to record musical practice sessions or confer-
ence meetings. If you want to record audio at a much higher level of sound quality, select
“PCM 96kHz.”
Hint:
· In PCM mode, non-compressed audio data will be recorded. In MP3 mode, compressed audio data will
be recorded. If you choose an option that offers better sound quality, the data size will be larger and the
remaining available recording time will be shorter. Select a Recording mode that will suit your purposes,
based on your priorities (better sound quality or longer recording time).
· If you plan to create an audio CD from the recordings, select “PCM 44.1kHz/16 bit”.

Introduction
Estimated available recording time (with internal 2GB memory)
* If you record multiple files, the total available recording time will be shorter than those estimated above.
* When you purchase the recorder, the manuals are stored in PDF format in the internal memory. Therefore, the actual
available recording time is less than estimated above.
* The largest available recording space (for continuous recording) in one file is 2GB.
■ About the ALC (Auto Level Control) function
The Auto Level Control function automatically adjusts the recording level in response to the
source level so that the resulting recording will be tighter dynamically.
■ Microphone sensitivity
You can set the microphone sensitivity level to high or low to accommodate the recording environment.
If the recorded audio level is too low or too high, change the microphone sensitivity setting.
Setting the microphone sensitivity
Press the [MENU/FOLDER] button while the main screen is displayed, select [REC MENU] → [MIC SENS], then
select [HIGH] or [LOW]. If the volume level is too low, select [HIGH]. If the volume level is too high, set [MIC
SENS] to [LOW].
■ Recording peak limiter
When the recording peak limiter is set to ON, the recorder reduces sound distortion by automatically adjust-
ing excessive peaks. It is recommended that you set the limiter to ON when you record audio.
Setting the recording peak limiter
Press the [MENU/FOLDER] button while the main screen is displayed, select [REC MENU] → [REC LIMITER],
then select [ON]. The peak limiter is available only when the ALC function is set to OFF.
