Attention: If you have a problem to use this service, be sure Milestone 312 is activated, the
keyboard lock is off and that the sound volume is loud enough.
2.3.2. Headphone using
If you do not want to listen to Milestone 312 over the speaker you can plug in any
headphones with a standard 3.5 mm jack on the right bottom side of the device. The
sound will then switch from the speaker to the headphones.
2.3.3. USB connection to the computer
You can connect your Milestone 312 to your computer to upload and download files such
as DAISY books, music files, voice messages, text files and more. The fast USB 2.0 Hi-
Speed port allows you quick transfer times, also for big data volumes. USB 2.0 Hi-Speed
is even faster than the often encountered USB 2.0 Full-Speed. You can also use the
connection to the computer to create your own folder structure on Milestone‘s internal
memory or on an inserted SD memory card. Or you can use the connection for simply
charging Milestone‘s battery, for this you will find further information under “Battery
charging”.
To connect it, just grab the provided USB Hi-Speed cable and connect Milestone 312 to a
computer with it. Plug the smaller USB end into the USB interface, which is located in the
center of Milestone‘s front end. The bigger end you connect with a USB interface on your
computer. Set-up of the connection is signalized with the message “Connection activated”
From a software point of view and for further interaction possibilities for computer
connections look under “Data management via computer” in this manual.
2.3.4. External Microphone using (Mic in)
Besides recording over the integrated microphone you have the possibility to plug in an
external microphone. Therefore use the connector on the right side of the front end. You
can plug in microphones with a 3.5 mm jack.
Attention: In case you have an early model of Milestone 312 with a serial number starting
with the number one, for example 134007, you can not connect an external microphone
with this connector. Please ask your dealer for an alternative or go to www.bones.ch for
further information.
2.3.5. SD Memory Card
Milestone 312 has a longish port on the right long side, where you can insert a memory
card. This memory card is a so-called SD card. SD stands for “Secure Digital”, which
denotes a world-wide standard for memory cards. These memory cards are available in
different memory capacities in your electronic shop. Many brands of SD cards exist on the
market and they are of different quality. We recommend SD cards from SanDisk, Kingston,
Transcend and Toshiba for untroubled usage.
To insert the card, press it until it locks in, but do not use force. To remove the card, just
give a short push on the card and it will disconnect from the socket.
By using a SD card you can enlarge your memory space by a large amount. Besides that,
you have a free medium you can exchange with friends to share your data, for example
voice messages, music files, audio books etc.
