4.1.3. Recorder
4.1.3.1. General information
Audio contains a Voice Recorder which allows you to record voice messages and sounds
over the integrated microphone. Shopping or to-do lists, interviews, schedule information,
memos, meeting agendas, recording of presentations or school seminars and addresses
are some possibilities which can be recorded. Of course nothing stops you using it as the
ultimate spy recorder for adventurous undercover activities on your mission impossible.
The integrated microphone is optimized for voice recording and filters bothering
background noises. So you even can record in a bus, car or plane. You will have clear play
back when you listen to it.
Records over the integrated microphone are saved as MP3 file with a quality of 64 kbps.
4.1.3.2. Use the Recorder
Press the “Selector” button on the front end until you hear the announcement “Audio”. Now
you are in the correct device.
Attention: If you have pushed “Selector” on M312 and it does not react, it might have been
in the sleep mode. In this case just press “Play” button and it will react. If you still have no
reaction, please check that keyboard is not locked, volume is on and battery has power.
To record messages, push “Rec” and hold it while recording. A short “click” signalizes that
the recording has started. For best results, speak at normal volume and hold the device at
a distance of approximately 10 cm (4 inches) from your mouth.
Milestone 312 stores messages in the present selected folder. If you want to check in
which folder Milestone 312 is located, do that with the Information Service in the Menu.
As an alternative of having to keep a button pressed during a recording, you may start a
continuous recording. Push and hold the “Rec” button and then additionally press “Play”
after a short “click”. The device will acknowledge the start of the continuous recording with
the sound sequence “low pitched-high pitched”. To terminate the continuous recording,
briefly press the “Rec” button again. The device will acknowledge the end of the
continuous recording with the opposite sound sequence “high pitched-low pitched”.
Furthermore continuous recording can be paused with “Play” and with a further push on
“Play” again to be continued.
In case you plug in an external microphone, as described under “External microphone
using“, Milestone 312 switches automatically from internal microphone recording to
external microphone recording. The handling is the same as with the internal recording,
but the quality of the records changes up to 256 kbps.
To listen to a recorded file use “Play” and Audio will play back the current file. When Audio
is playing a file it differs between downloaded files and files which are recorded on
Milestone 312. When you play back your own recording, M312 is programmed to stop after
this file and does not automatically play the next file. For example this allows you to
process a recorded shopping list step wise. To play the following recording press “Right
arrow”. On the other hand when you play a file, not recorded on M312, Audio automatically
plays the next title, as usual for music players.
Attention: Voice recordings and music files should not be mixed up in one folder, because
M312 processes these two file types differently. So depending on the file type, M312
would, after a music file, continue automatically with the next file and stop immediately
after a voice recording.
