2.2 Layout description
2.2.1. The operating surface
Holding your Milestone 312 Ace in your hand , you will find five buttons on the Front Face of the machine.
In the middle is a large key and four other buttons are arranged around it in the shape of a cross.
The middle button can be identified not only by its size and central location, but also by its smooth surface.
The name of this button is "Play". Now we look at the buttons surrounding the "Play" button.
If you move your thumb down, you will feel the "Mode" button. The "Mode" button is the same size as the
"Play" button, but marked with a tactile X.
Below this you will feel the small, round holes of the speaker. Returning to the buttons, the other three
keys are slightly smaller.
Immediately to the left of the central "Play" button, you will feel the "Left arrow". You will recognize it by
the highlighted arrow pointing to the left.
If you move to the right of the "Play" button you will find the "Right arrow", also a tactile arrow but
pointing to the right.
The fifth and final key is located above the "Play" button. This is the "Rec" button and you will find a small
round indentation in the center.
The four buttons, which are arranged around the "play" button, are often used in the style of a navigation
cross. With the "Left arrow" you navigate to the left, the top "Rec" button takes you to the top with the
"Right arrow" to the right and the bottom "Mode" button you move down.
Now you are familiar with the user interface of the keys of your Milestone 312 Ace.
In addition to the aforementioned buttons there is a small indentation in the upper left corner for the red
LED.

protrudes from the device. In the middle of the top side is an elongated opening. This is the USB port. The
cable is connected here for connection to a computer. To charge the battery of your milestone, connect
the charging cable to this port. Far right on the top edge you will find the connector for external
microphones and line-in connections.

standby mode for several weeks without recharging or allows continuous operation of up to 20 hours. This
value is reached when listening to music or books on headphones with normal playback speed and
medium volume. Please note that the playback via the built-in speaker requires more energy. Also high
playback speeds, high volume and playing text files require more energy and consequently result in a
shorter running time per battery charge.
2.3.2. Connecting Headphones
If you do not want to hear playback of your Milestone 312 Ace through the internal speaker, you can
connect any headphones with a 3.5 mm jack on the bottom right on the device. The output is then
switched from speakers to headphones. Please note that your Milestone 312 Ace has Two independent
volume levels - one for the internal speakers and one for the headphones.

To connect your Milestone 312 Ace to a computer, you can use the supplied USB cable. Connect the cable
end with the small mini-USB plug to the mini-USB port on the top of your milestone. The end with the
somewhat larger USB plug will fit into any traditional USB jack on the computer.
Your M312 Ace confirms a successful connection with the message "Connection activated" and appears as
an external drive named "M312ACE" on your computer. Now you can manage the computer's files and
folders on both devices, replace, rename, delete or copy. Even with large amounts of data enables you to

3.2. Data management via computer

12
Before you can listen to music files, texts or books, you must first transfer them to the Milestone 312 Ace
on an SD card or to the internal memory with the included USB cable. The structure and names of the
folders can be selected freely. The following section explains the procedure in detail.
3.2.1. The M312 Ace drives during active computer connection
Use the supplied USB cable to connect your Milestone 312 Ace with the computer. When connected your
computer recognizes the M312 Ace and the inserted SD memory card as two additional drives. One drive is
named "M312ACE". This is the 12 gigabyte comprehensive, internal memory of your Milestone 312 Ace,
which is at your full disposal.
The other visible drive is the SD memory card, which is located in the Milestone and is commonly
recognized as a "Removable Drive". If your Milestone 312 Ace is not equipped when connected to the
computer with an SD card, only the internal memory will appear with the label "M312ACE" on the
computer. When the data transfer has been completed successfully, eject your Milestone 312 Ace and the
SD card properly from the computer before disconnecting the USB connection.
3.2.2. Create a folder structure with the computer
With the computer, you can create your personal folder and directory structure to organize music, voice
recordings, text files, books and radio recordings. It is also possible to use any number of subfolders and to
rename individually. This applies to both your available drives the M312 Ace, the internal memory of 12 GB
and the external memory, the SD card. Folders are just containers where your files are stored. Your M312
Ace comes with preinstalled folders that you can always rename or delete on the computer. If you access it
later, all the folder names are read by M312 Ace.
The following graphic is an example of a possible folder structure.
Note: There are applications which automatically create a specific folder, such as "Radio" the list of station
names or recording broadcasts.

13
3.2.3. Save or delete files in the folder structure
3.2.3.1. Data transfer via computer
On M312 Ace you can save text, music, books and more.
Select the desired files on the computer and "Copy". Then open the drive of your Milestone 312 Ace or its
inserted SD card and save the previously selected data with the command in the desired folder. Make sure
that enough free space for your files exists. In addition to the comprehensive 12 gigabyte internal memory
of your Milestone 312 Ace, you can use SD and SDHC cards up to 32 gigabytes to archive your documents.
Please observe the following guidelines:
Extract CDs to your computer before you copy them to M312 Ace:
In the application "Audio" on your Milestone 312 Ace files of formats MP3, AAC, WMA, WAV, MP4, M4A,
M4V files can be played, as well as text files in TXT and DOC. These formats can be copied directly to the
Milestone. However, commercially available music CDs must first be converted with a program such as
CDex, Windows Media Player or iTunes, so that your M312 Ace can play the music files. This is the usual
process to save music files to a computer. The above-mentioned programs convert the music tracks into
smaller, universally usable formats.
Save each book in a separate folder:
The application "Books" reads your M312 Ace digital books in the DAISY 2 format, DAISY 3, EPUB, Audible
AA and AAX. Please store each book in a separate folder to keep track and to avoid mixing with files of
other books.
3.2.3.2. Delete via computer
If you want to delete data from your Milestone 312 Ace, you can do this either with the appropriate hotkey
or by connecting the M312 Ace to a computer. If you want to delete files or folders on the computer, use
the delete command of the PC or Macintosh operating system.
Note: If you delete the data on a Macintosh computer, make sure the trash bin of your computer will be
emptied. Otherwise, only the link instead of the entire file is deleted and no space released. Eject your
Milestone 312 Ace properly from the computer before disconnecting the USB cable.
4. Basic Applications
This chapter describes how to use the three applications "Audio", "Books" and "alarm clock", which are
included in the basic functions of your Milestone. The most versatile of these applications is called "Audio"
and combines the following main features: Music Player, Text To Speech Player, recorder and radio
stations. The application "Books" opens the door to the world of digital audio books. This application will
play the book formats DAISY, Audible, EPUB, NLS and BookShare. The application "Clock" is an easy to
use alarm clock which makes sure that you will be woken up on time and also includes a handy timer and a
stopwatch.
4.1. Audio
The application "Audio" is very extensive and plays a wide range of file formats. In audio, you can listen to
your music collection or read a text file. Audio combines a music player with a text-to-speech player. In
addition, Audio is a full-fledged recording device. You can create your own voice messages with the built-
in microphone, or high-quality recordings of concerts, meetings and so on recorded through an external
microphone. All files whether music, text or voice memo can be stored in an arbitrary folder structure, like
a computer. This folder structure can be created and adapted via a USB connection to the computer.
4.1.1. General functions of Audio

14
The following general functions are available in "Audio". To get there, please press the "Selector" until you
hear "Audio".
4.1.1.1. Folder navigation in Audio
The application "Audio" allows M312 Ace to navigate freely through the entire computer folder structure
on the internal memory or on the SD memory card. To do this, use the four buttons, which are arranged to
"play" around as navigation cross. With "Rec" you go up to a higher level. With "Mode" you reach the next
lower level. In the vertical axis, so you can navigate with "Rec" and "Mode"., or move horizontally using the
two arrow keys.
Example: Suppose you have an SD memory card in the M312 Ace with two folders, "Music" and "Text". In
the folder "Music" you have the subfolders "Rock", "Pop" and "Classic". In the folder "Text" are the two
subfolders, "newspaper" and "love stories". Now press "Rec" repeatedly until you hear a short beep,
followed by the message "Internal Memory" or "External Memory". "Internal Memory" stands for the 12-
gigabyte memory of Milestone 312 Ace and "External Memory" stands for the SD memory card, which is
inserted into the Milestone. With "Rec" you can switch from one to the other type of memory and are then
in the root directory. To use the contents of your SD memory card, press the "Rec" button until you hear
the announcement "External Memory". You are now in the root directory of the external memory, the SD
card. Use the arrow keys to switch between the various folders "Music" and "Text". Now select the folder
"Text" and then press the "Mode" button to access the contents of the "Text" folder. Immersion in a deeper
level is confirmed by a "high-low" beep sequence. Milestone reads the folder names in alphabetical order,
in our case, first "Love stories". If you now press "mode" again, you are in the folder "Love stories" and can
select the desired text document with the arrow keys.
Tip: When a folder contains many files or subfolders, you have the option to go directly to the first or last
position. Press and hold the "Right arrow" and at the same time, press the "Play" button to reach the last
item in that folder. With the "Left arrow" and "Play" you reach the first position in the folder.
4.1.1.2. Delete files and folders with M312 Ace
M312 Ace allows you to directly delete files and folders without connecting to a computer. The following
options are available to you for this purpose:

"Play" button. When you release the two keys, the file is deleted. This can only be canceled during
playback or up to 10 seconds thereafter.
To delete all files in a particular direction:
To delete all the files in one direction, simultaneously press the "Mode", "Play" and one of the two arrow
keys three keys. This combination must be held down for at least two seconds. The deletion of all files will
then be executed in the direction indicated by the arrow key, including the file in which you are currently
located. A long beep sounds at the beginning of the deletion and is followed by a short one once the files
have been removed.
Warning: This function is only available in pause mode.
Deleting a folder:
Select the folder you want to delete. Press and hold the "Mode" button and press the "Play" button. After 3
seconds Tap again on "Play". Then release the "mode" key. The deletion process for folders with extensive
content may take a few seconds. This process is signaled by a ticking sound.
4.1.1.3. Setting up a shortcut to a folder
M312 Ace allows you quick access to frequently used folders. You can select up to five arbitrary folders
directly with a key combination, instead of having tonavigate laboriously through the entire folder
structure.

15
The linkage of folders with a certain key combination can be achieved by navigating to the desired folder,
then select it with the "Mode" button.
Now hold the "Selector" button and press in addition one of the 5 front buttons. If you hold down the two
buttons for 3 seconds, the device will accept the selected location and confirm that the previously pressed
key combination has been assigned to one of five preset folders.
Overall, you can assign five folders with a hotkey and select them directly. To select a preset folder later,
press "Selector" and tap in addition briefly on the correspondingly assigned front button.
Note: The five available shortcuts may already be assigned to specific folders in delivery of the unit. This
assignment can be changed at any time.
4.1.1.4. Naming folders via Voice Recording
You can rename the folder name directly via voice recording in your own voice or assign the label on the
computer and read aloud via text-to-speech. To assign a folder name using voice recording, first select the
folder with the "Mode" button. Now hold down the "Rec" button. Once you hear a clicking sound, hold the
"Rec" and the "Mode" buttons until the message "Folder" is heard. Then you can select the desired folder
name and speak into the microphone, then release the two keys. The stop recording is signaled by the
tone sequence "high-low". Next time you navigate to the named folder, your voice recording will sound as
the folder name. You can overwrite the recorded label attached to any folder as often as you like. To
remove a recorded folder name, delete the file "FOLDER.NAM" in the folder using a computer.
You can re-record previously deleted folder names directly using your Milestone 312 Ace, if you re-record
the folder in question previously by renaming it as just described with "Rec" and "Mode". Then you will be
able to erase the recorded voice label with the key combination "Mode" and "Play". The folder is then
again assigned to the computer name.
Tip: An SD memory card can also be labelled with your voice. Pres "Rec”several times " until you get to
the top level and switch to "External Memory". Perform the same sequence of how to designate a label for
the folder. After that, your recorded name will be announced when the SD card is inserted.
Note: If a folder name has been specified both on the computer, as well as by voice name, only the
voicename is played.
4.1.1.5. Fast Jump
Fast Jump is a navigation function, which is applicable within the application "Audio" in each file. Fast
Jump is especially useful for large files, because then you can jump quickly to a desired portion. To start
Fast Jump, during the playback of a file, hold down the "Selector" button and tap "play". With this key
combination you are now jump directly to the center of the current file. This Fast Jump is active while the
"Selector" button remains depressed throughout its operation, otherwise Fast Jump is terminated.
Therefore, Keep "Selector" pressed in order to determine the position in the file. With the "Left arrow" you
now get into the middle of the first half. This means you can reach the first quarter, or 25% of the file.
Suppose, however at times, that you have the "Right arrow" pressed and thus arrived at 75% of the file. If
you press the "Left arrow" you reach 62.5% of the file, so the middle of 50% and 75%. You can proceed
with this division until you reach the desired entry point. After each time you press one of the arrow keys,
the playback will start automatically, so you have an idea of where you are right now. If you press "Play"
while the "Selector" button continues to be held, this will take you back to the middle of the file.

16
Note: Fast Jump only works while playing a file. If no file is played, it activates the key combination
"Selector" and "Play" quick access to a particular folder, such as "Setting up a shortcut to a folder" as
previously described.
4.1.1.6. Set and delete audio bookmarks
To set an audio bookmark, press during playback the "Rec" button for 2 seconds. Your M312 Ace confirms
the operation with the announcement "Audio Bookmarked" and calls the corresponding number of the
bookmark. Audio bookmarks may be used in any compatible files, such as text files, music tracks and radio
recordings. you can retrieve Your stored audio bookmark in the "Local Settings". Under "Audio
bookmark", move with the arrow keys to scroll through the set bookmarks. Each audio bookmark entry
contains a number, file information, and a brief preview of the reading position. When you reach the

acknowledges the start of the continuous recording with the sound sequence "low-high". To terminate
continuous recording, press the "Rec" button. Stopping the recording will be confirmed with the sound
sequence "high-low". To pause during a continuous recording, press the "Play" button. Pressing "Play" will
resume the recording.
4.1.4.3. Location of a voice memo
Milestone 312 Ace stores your voice note exactly where you are at the time you begin your recording, be it
in the internal memory or on the SD memory card.
If you have created a folder structure, you go first to the desired folder and then record your voice
message. With the "Mode" button to open the folder in question, which is confirmed by the sound
sequence "high-low". It is also possible to store voice recordings along with other files in the same folder.
After listening to a voice memo in the "Audio" application, Milestone will stop playing. Music and text files
on the other hand are played continuously in sequence.
Note: The application "Audio" allows you quick access to up to five folders. The keyboard shortcuts can be
used, for example, to return to your voice recording folder without navigating through the entire folder
structure. More information can be found in the section "Setting up a shortcut to a folder".
4.1.4.4. Listening to a voice memo
To play back your recording, press the “play”button when recording is stopped. If you have recorded more
than one message, use the arrow keys to select a voice memo.
4.1.4.5. Recordings via the internal microphone
By default M312 Ace records via the integrated microphone. The internal microphone is optimized for
voice recording and reliably filters out noise. Even shots on the bus, train or plane are captured in high
quality. To achieve optimum results, please speak at a normal volume and hold the device about a hand‘s
length away from your mouth. The integrated microphone is located in the upper left corner, near the

19
small red LED light. Recordings via the internal microphone are saved as MP3 files with a quality of 128
kbps.
4.1.4.6. Recordings from an external microphone or other line-in sources
In order to improve the quality of your voice recording, you can connect an external microphone. It is also
possible to use a stereo audio cable to connect external audio sources to the line-in port on your Milestone
312 Ace. As described in the section entitled "External microphones and line-in" M312 Ace automatically
switches from the internal microphone to record on the external microphone or line-in. When recording
with an external microphone, it does not change the mode of operation, but the recording quality is
considerably improved.
Once an external microphone or a stereo audio cable is connected, "Local Settings" recording-related
choices appear in the menu which you should definitely consider and change them if necessary before
recording something. The options are:
•Recording source: External microphone or line-in.
•Recording environment conference, outdoor, studio or your own settings.
•Recording quality: MP3 128-320 kilobits per second (kbps).
•Channels: Stereo or Mono.
•Recording volume: Automatic or 10 to 100 percent.
•Noise Filter: On / Off.
Make the changes you want to achieve the best possible quality.
Keep in mind please that the correct specification of the recording source is important. Your M312 Ace
distinguishes between an external microphone and a line-in source. If you connect, for example, a radio,
CD, DVD player or PC sound card and in the "Local Settings" select an external microphone instead of
Line-in to specify the recording source, connected devices could (in very rare cases) be damaged.
Check the other options in the "Local Settings". From the item "Recording environment" you can choose
between 3 predefined profiles and 3 custom profiles (for example, "Own setting 1"). The latter can be
defined by yourself. For this you can use the settings "recording quality", "channels", "Recording Volume"
and "Noise Shield" which are all available. In the case of the predetermined profiles, such as "studio", the
parameters are not changed.
Note: The "Noise Filter" reduces noise and allows voice recordings in vehicles. The rumble of gears or
motors is effectively suppressed by a highpass filter at 100 Hertz.
Note: Recordings via external microphone or line-in can be monitored through headphones.
Caution: Do not change the recording source if an "External microphone" is used. This setting provides the
connection with 2 volts and could damage connected devices, which can not handle additional power.
4.1.5. Send Radio (FM Transmitter)
One of the most interesting innovations of M312 Ace is sending content via VHF to a household or car
radio. This allows all content within about 10 meters to be received on a regular radio receiver in very high
quality. Typical applications are listening to books or audio on a home stereo system or on the road in a
car.
Send Radio is activated from the menu "Local Settings" in the functions Audio, Books and Radio. When
appropriate menu item is selected, right arrow activates and left arrow deactivates Send Radio. the
transmission frequency can be increased by pressing the "Right arrow" the frequency is increased by a few
steps until it reaches 108 megahertz and will then be decreased down to 87.5 megahertz. To switch off
transmitting, press the "Left arrow".
To transmit effectively, an antenna is required. Plug a pair of headphones into the headphone jack. Audio
will sound simultaneously from the built-in speakers. In practice, simple, inexpensive headphones prove

20
very effective. Please insert keeping the wire straight and untangled. Please do not use knotted cable or
cable with coils.
The active condition of “Send Radio”is retained when the Milestone is switched on. The frequency is also
stored in the control file CONFIG MILESTONE.TXT.
If you switch on the radio function, receiving radio transmission is automatically switched off and resumed
when selecting another function.
