Message Cause/Remedy
Invalid Operation
Yo
u cannot divide or set a track mark in files in the folder
in the playback‑only area (the “ Music” and “ Podcast”
categories).
Wh
en a microSD card has a bad block on it, the card
cannot be written to. Prepare a new microSD card to
replace the current one.
The file name has reached the maximum number of
characters; you cannot divide the file. Shorten the file name.
The “Divide All Track Marks” function cannot be used
because there is a track mark within 0.5 seconds from the
dividing position.
The “
Divide All Track Marks” function cannot be used
because there is a track mark within 0.5 seconds from the
beginning of a file or the end of a file.
The
file length is less than 1 second; you cannot divide such
a short file.
The “
Divide at Current Position” function cannot be used
at a position within 0.5 seconds from the beginning of a file
or the end of a file.
New File
The f
ile being recorded has reached the maximum size
limit (2 GB for an LPCM file, and 1 GB for an MP3 file).
The file will be divided automatically and recording will
continue as a new file.
Change Folder
I
f t
here are no files in the
or folder, no folders are
displayed in the display window. A folder containing a file
will be displayed.
Ca
nnot Divide ‑ Exceeds
Max 199 Files in Folder
Wh
en there are already 199 files in the selected folder or
the total number of files stored on the IC recorder exceeds
the maximum, you cannot divide a file. Erase some files
before dividing a file.
Same File Name Exists
A f
i
le of the same file name already exists in the folder, so a
file cannot be created or renamed.
Erased Track Marks too
near Divide Point
Wh
en there is a track mark set within 0.5 seconds from the
dividing position, the track mark is automatically erased.
No operation with
microSD Card
Yo
u cannot set an alarm in a file stored on a microSD card.
Switch the memory media of the IC recorder to “Built‑In
Memory” (
p.
34).
Check the Volume Level*
The v
olume of the playback sound exceeds the specified
level. Adjust the volume to a moderate level.

System Limitations
There are some system limitations of the IC recorder. Troubles as mentioned
below are not malfunctions of the IC recorder.
Symptom Cause/Remedy
You cannot display or play
back music files in order.
If y
ou have transferred music files using your computer,
those files may not be transferred in order of transfer
because of system limitations. If you transfer music files
from your computer to the IC recorder one by one, you can
display and play back the music files in transferred order.
A file is divided
automatically.
The f
ile being recorded has reached the maximum size
limit (2 GB for an LPCM file, and 1 GB for an MP3 file).
Therefore it is automatically divided.
Yo
u cannot enter lower‑
case characters.
Dep
ending on the combination of the characters used for
the folder name that was made on your computer, those
characters may change to all capitals.
“” is displayed in place
of a folder name, title,
artist name, or file name.
A ch
aracter which cannot be displayed on the IC recorder
has been used. Using your computer, replace it with one
which can be displayed on the IC recorder.
The remaining recording
time becomes shorter
when you divide a file.
Yo
u need a certain amount of free space for a file
management area to divide a file, therefore the remaining
recording time will be shortened.

Listening for a Lifetime
Selecting fine audio equipment such as the unit you’ve just purchased is only
the start of your musical enjoyment. Now it’s time to consider how you can
maximize the fun and excitement your equipment offers. This manufacturer,
t
h
e Consumer Electronics Association (CEA)® and the American Speech‑
Language‑Hearing Association (ASHA) want you to get the most out of your
equipment by playing it at a safe level; a level that lets the sound come through
clearly without annoying blaring or distortion and, most importantly, without
damaging your sensitive hearing.
Sound can be deceiving. Over time your hearing “comfort level” adapts to
higher volumes of sound. So what sounds “normal” can actually be loud and
harmful to your hearing. Guard against this by setting your equipment at a safe
level BEFORE your hearing adapts.
TO ESTABLISH A SAFE LEVEL:
Set your volume control to the lowest level where you can hear the music
comfortably and clearly. Prolonged exposure to anything over 85 decibels can
cause gradual hearing loss.
Once you have established a sound level where you can hear the audio
comfortably, clearly and without distortion, set the dial and leave it there.
See if your music player has a volume limiter that allows you to set a safe
listening level by establishing a maximum volume level on your player. This is
a great solution for parents to ensure their children listen at a safe level.
Limit listening time to give your hearing “quiet breaks.”
BE SURE TO OBSERVE THE FOLLOWING GUIDELINES WHEN
WEARING YOUR HEADPHONES OR EARBUDS:
Do not turn up the volume so high that you can’t hear sounds around you.
Do not use headphones or earbuds while operating a motorized vehicle; it
may create a traffic hazard and is illegal in many areas.
Used wisely, your new sound equipment will provide years of fun and
enjoyment. Since hearing damage from loud noise is often undetectable until it
is too late, this manufacturer, CEA and ASHA recommend that you avoid
prolonged exposure to excessive noise. The following list of sound levels is
included for your information so that you can better protect your hearing.
