EMM Tiny Module
The EMM Tiny Module is designed for professional voice record-
ing on Flash media that can be downloaded into a PC. This mod-
ule is the development of the Tesystems Company’s miniature
digital voice recorders of the EM Tiny model. The module has
extremely small size and weight, long recording time (depending
on the modication from 18 hours up to 890 hours at sampling
rate 8 k Hz, compression – 2 bits ADPCM), reduced power con-
sumption, wide band range (100- 10,000 Hz), and a wide dynam-
ic diapason. As the module does not have moving parts, it can
function in challenging environment: at wide temperature range,
dustiness, or shaking.
Using the supplied USB cable, the module can be connected to
a computer. The supplied software works with Windows 2000/XP
and allows storing audio recordings as standard audio les and
programming module’s parameters. The module can work in a
ash-disk mode with memory capacity depending on modica-
tion from 128 MB up to 6 GB.
The module’s rmware can be renewed using a USB interface.
The module has:
• A built-in real time clock, a calendar, and a timer that can
start recording on a preset time, once and repeatedly.
•The Voice Activating System (VAS) that allows compressing
pauses in audio messages while increasing real recording
time. This system saves memory space while the time in-
4
tervals stay the same. When recordings are uploaded onto
a computer, pauses can be restored as silence or skipped
depending on previous settings.
• The LEDs that provide indications depending on modes of
operation.
• The switch that provides control of module’s work.
In ash-disk mode, the module can be used for storing and trans-
ferring any type of data. The module can function as a ash me-
dia and voice recorder simultaneously. Distribution of memory
space is assigned by the user.
Password protection provides security of audio recordings and
the module’s settings. In addition, every recording has a digi-
tal watermark containing date and time of the recording along
with the module’s identication data and history of the recording
changing.
The module’s software supports the multi language interface.

k is a coefcient that shows how many times the maximum re-
cording time decreases relatively to the maximum recording time
in the 2-bit ADPCM mode when recording mode is changed. For
instance, maximum recording time (1120 modication, without
compression, sampling rate 8 kHz, k=5) is 1120/5=224
minutes.
Sampling rate defines the recorded frequency band that is
lightly less than a half of the chosen sampling rate.
The best recording quality is in a mode without
compression, then as the quality decreases: Logarithmic, 4-bit
ADPCM, and 2-bit ADPCM. In addition, modes with high
sampling rate increase the consumption current of the module.
Working with the Module
Preparing for Work
The Module is designed as a printed circuit board (PCB) that can
be installed in to a user’s device for sound recording functions.
To operate, the module has to be connected to a power source
and an external audio source.
8
There are labels on the module contacts in the description of
module’s appearance in the manual’s appendix.
The user can connect an external indicator (LED) and an exter-
nal control, for instance, a switch. If the external control is con-
nected to the module, the module built-in switch has to be in the
STOP position.
To turn on the module, after power supply is provided, set the
switch in the RECORD position for 2-3 seconds and then back to
the STOP position. The indicator has to ash three times showing
that the module has started self-testing. After 5-10 seconds, the
indicator will blink for the fourth time (the length of the fourth ash
depends on the module’s memory capacity and can be some
dozens of seconds). After this the module is ready for work.
To provide a reliable start, it is recommended to make a pause
for 30-60 seconds between turning the module off and on.
Choosing the Recording Parameters
Before recording, use the RecManager program to choose the
recording settings (for instance, quality/ compression relation).
These settings will be saved if power supply is turned off.
Default Settings
Sampling rate – 16 kHz, without compression, VAS -off, mono,
timers are off.

Voice Recording
To turn on the recording, set the switch in the RECORD position
(or connect the K and GND contacts). The module will ash ve
times and then blinks in several sequences while recording. To
turn off the recording, set the switch into the STOP position (or
disconnect the K and GND contacts). When the module stops
recording, the indicator will ash once (the length of this ash
depends on memory capacity and can be some dozens of sec-
onds).
During the recording process, the indicator’s blinking will show
the approximate level of supply voltage and memory capacity.
The rst sequence of ashes (1-3 ashes) shows the level of
supply voltage and the second sequence shows free memory
capacity (see the manual’s appendix for additional information):
4 ashes -0..25%, 3 ashes – 25-50%, 2 ashes -50-75%, and
1 ash -75-100%.
The sequences are going with 1.5 sec intervals; the sequences
are repeated during a period of 6 sec.
Pay attention that recording will be stopped if the supply voltage
is below the minimal level or there is not enough memory space
for the recording. It is recommended to control the indicator blink-
ing while recording.
The Voice Activating System (VAS) mode lets considerably (up to
100 times) lower memory consumption and consumption current
while recording.

Playing the Recordings
Download the recordings onto a PC using the RecManager pro-
gram. Then play them using any audio program, for instance,
Windows Media Player.
Connecting to a PC
The module has to be connected to a PC to play/save record-
ings, set the module’s parameters, and make other operations.
Turn on the PC. Install the RecManager program using the sup-
plied CD (/EdicMiniTiny/ folder)
Connect your module to a computer using the supplied USB
cable. The module LED will light. If it is the rst time connect-
ing, OS Windows will suggest installing the drivers. Follow the
instructions in the Automatic Installation dialog windows of the
Installation Wizard. While installing, this message can appear:
The installed software has not been tested for compatibility with
Windows XP. Click Continue.
Start the RecManager program. If the program is in demo mode,
turn this mode off in the Recorder menu (Ctr+P hot key). The
computer will detect the module and the program will show the
module’s ash media content.
As you nished your operations, exit the program. Disconnect
the USB cable.
