Version 05.08.29

Introduction
Thank you for purchasing the Edic-Mini LCD digital voice recorder
(DVR). Prior to operation, read the operation manual thoroughly.
Purpose
Voice recorders of Edic-mini LCD series are professional devices
intended for making high quality record of voice messages into built-in
flash-memory. You can playback recorded messages using an
earphone and save them in your computer as standard sound files.
Voice recorders feature extremely small dimensions and weight, long
record time (varies with the model up to 600 hours) and standby
operation (up to 1000 hours), a wide dynamic range and highly
sensitive built-in microphone. Due to the absence of moving parts, the
DVR functions even under conditions of strong vibration, dustiness
and low temperatures.
The supplied USB adapter provides high-speed data exchange
between the DVR and computer (1.5 Mb). The supplied on the CD
software makes it possible to save the recorded messages as
standard sound files, to set the DVR parameters and to control
admission to the DVR functions. You may use your DVR for message
recording, as well as a flash-disc at the same time, to store and
transfer data of any format.
For the user's convenience while operating the DVR, there is a push-
button manipulator (joystick) and a liquid-crystal display to indicate all
the information needed, including built-in timer and real time clock.
The DVR has a Voice Activating System (VAS) which effectively
compresses pauses in messages, therefore increasing the actual
record time. The pause length can be restored at further file
processing with the software supplied.

Prestarting procedures
Battery installation
We do recommend that only the batteries, produced by well known
manufacturers should be used in the DVR. In this case you may
expect your DVR to work continuously. Other battery types of the
same dimension-type may provide much less DVR operation time in
Record and Playback modes, even if they are called compatible and
announced to have better features.
When inserting the battery, make sure you have observed the polarity.
Warning!
Special attention should be paid to polarity while inserting the battery:
the positive battery contact is to be upward (the top side of the DVR is
where the joystick and the display are).

Fig.2
Push the joystick up to pause recording, PAUSE will appear on the
display.

15
To continue recording, press the button once again.
If you push the joystick down, recording will stop, the DVR will go to
Standby mode.
If trere is no more free memory,the DVR will automatically go to Sleeping
mode.
Recording may be saved either in the cycle buffer mode or in the line
messages mode. The DVR can provide some memory size to the
cycle buffer. (See Profile setting)
Warning! When recording into the cycle buffer (cycle record), the
DVR will start recording into the record beginning (i.e. deleting the
previously recorded data), as soon as the provided memory space
comes to the end. The time of the current record will go on, but the
remaining memory size will stay constant on the display.
Each recording made is marked with the time and date by means of the
built-in real time clock.
You may adjust your DVR (see Setup mode) to record in the VAS
mode. This will allow you to compress the pauses in messages
efficiently therefore the available recording time increases. Using this system
saves memory in pauses, but stores information about time intervals.
The pause length can be restored at further file processing with the
14
supplied software.
In the VAS mode, while recording into flash memory, the Record
symbol will be lit on the display. If the signal does not exceed the fixed
level, and it is not recorded into flash-memory, there will be Record and
Stop symbols on the display
You can make the VAS mode settings with the supplied software.
The VAS working algorithm is as follows: the DVR controller sleeps for
T1 time, then it switches on for T2 time and analyzes the signal. If it
discovers X1 threshold exceeding by the signal during this time, the
controller attempts to discover X2 threshold exceeding by T4 time
during T3 time. If the controller succeeds, the record starts, otherwise
the recorder continues sleeping. The record stops, if the signal does
not exceed X3 threshold during T5 time. And so on, in cycle. The user
can set T and X values corresponding to software settings to conform
to specific requirements.
Playback mode (PLAY)
When you push the joystick down, PLAY will appear on the display. If
you want to playback any record, press the push button to confirm
choosing the Playback mode. Push the button right or left to select the
record number to be played. Then press the button, and the playback
of the chosen record will start. The display will show the following
information (Fig. 3):
- In the symbol line battery charge indicator and mode symbol;
- In the numeric line on the left: playback time (hours and minutes), the
separator blinks at a 2-second interval, on the right: volume level;
- In the alphabetic line on the left: the size of the record segment
played, as the percentage of the total record size, on the right: the
number of the record being played.

15
To continue recording, press the button once again.
If you push the joystick down, recording will stop, the DVR will go to the
Standby mode.
The DVR will automatically go to the Sleeping mode, if there is no
more free memory.
Record may be carried out either in the cycle buffer mode or in the line
messages mode. The DVR can provide some memory size to the
cycle buffer. (See Profile setting)
Warning! When recording into the cycle buffer (cycle record), the
DVR will start recording into the record beginning (i.e. deleting the
previously recorded data), as soon as the provided memory space
comes to the end. The time of the current record will go on, but the
remaining memory size will stay constant on the display.
Each record made is marked with the time and date by means of the
built-in real time clock.
You may adjust your DVR (see Setup mode) to record in the VAS
mode. This will allow you to compress the pauses in messages
efficiently, therefore increasing the real record time. Using this system
saves memory in pauses, but stores information about time intervals.
The pause length can be restored at further file processing with the
14
supplied software.
In the VAS mode, while recording into flash memory, the Record
symbol will be lit on the display. If the signal does not exceed the fixed

controller attempts to discover the X2 threshold exceeding by T4 time
during T3 time. If the controller succeeds, the recording starts, otherwise
the recorder continues sleeping. The recording stops, if the signal does
not exceed the X3 threshold during T5 time and so on in cycle. The user
can set T and X values, corresponding to software settings, to confirm
to specific requirements.

Press the button to confirm choosing this mode. Push the joystick right
or left to select the number of the recording (NUM) to be erased and press
the button. The available memory size will be indicated on the display, in
percent according to the total size. If you press the button again, the next recording
will be offered to be erased. If you have erased all the recordings or there
are no recordings, EMPTY will appear on the display. It means that 100%
memory is free. Press the button up to exit this mode.
Tuning mode (REC PR)
The DVR provides eight settings of recording parameters
(profiles). The DVR has the following preset profiles in the factory
configurations. (Each profile contains its own set of recording parameters,
including quality and voice compression at recording, VAS
parameters, recording in linear/circular buffer). You can set profiles as
you wish.

You can change the profile parameters using the Setup mode. (See
Setup mode) We recommend you to select the profile before
recording. For that, push the button down three times, you will go to the
Tuning mode. Then press the button, and by pushing it right or left, select
a profile (from 0 to 7). Press the button and PR SET will
appear on the display. It means that the selected parameters are set.
Then push the button up to go to the Standby mode.
Remember, that the record time depends on the record
quality: the higher is the quality, the shorter is the time. You may
approximately calculate the record time using the coefficient stated in
the technical characteristics. To do this, divide the maximum record
time of your DVR by the coefficient corresponding to the chosen
parameters. In the Tuning mode, if without a push-button activity for 14
seconds, the DVR will switch to the Energy-saving mode. The chosen
profile will be saved. These settings are also saved when replacing the
battery.
Setup mode (SETUP)
Push the button down four times to switch to the profile Setup mode.
Here you can set the real time, check the available memory size and format
it completely as well. Then press the button to enter the Setup mode.
Then, pushing the button down, you can select from the following
items (in circle):

Profile setting mode
Select the Setup mode (push the button down four times, then press
it), then push the button down once and press it. The DVR is in the
Profile setting mode now.
You can select parameter values by pushing the joystick left or right,
and switch to the next parameter by pressing the button. Push the
joystick up to return to the Setup mode.
First of all, select the profile number (NUM) by pushing the button left
or right, and press the button. The DVR will offer to set (in cycle):
1. Audio sample rate (FREQ) of 4, 8 or 16 kHz.

Set it by pushing the button left or right. Push the button down to go to
the next parameter setting. Push the button up to return to the Setup
mode (without saving the selected parameters).
If you press the button, the setting will be completed, and PR SET and
the profile number will appear on the display.
2. Audio compression format. Push the button right to select the
format, and left to select the parameter value.
- NO recording without compression;
- LOG logarithmic compression. You can set the sensitivity parameter
(1, 2, 4, 8 or 16) by pushing the joystick left. The parameter depends on
recording conditions. You should set a low parameter value to make a
high quality record of a weak signal; the strong signal will be recorded
with distortion. If the parameter value is big, loud signals will be
recorded at high quality, but low signals can be fuzzy.
- ADPCM Adaptive Differential Pulse Code Modulation. You can set
the parameters (2 or 4) by pushing the joystick left.
You may set the following quality, formats and density of data
recording:
- Without compression (linear), sample rate is 16 kHz, 256 Kbit/s, k=16
- Without compression (linear), sample rate is 8 kHz, 128 Kbit/s, k=8
- Without compression (linear), sample rate is 4 kHz, 64 Kbit/s, k=4
- Logarithmic compression, sample rate is 16 kHz, 128 Kbit/s, k=8
- Logarithmic compression, sample rate is 8 kHz, 64 Kbit/s, k=4
- Logarithmic compression, sample rate is 4 kHz, 32 Kbit/s, k=2
- Modified 4-bit ADPCM, sample rate is 8 kHz, 32 Kbit/s, k=2
- Modified 2-bit ADPCM, sample rate is 8 kHz, 16 Kbit/s, k=1
- Modified 4-bit ADPCM, sample rate is 4 kHz, 16 Kbit/s, k=1
- Modified 2-bit ADPCM, sample rate is 4 kHz, 8 Kbit/s, k=0.5
where k is the coefficient, showing how many times the maximum
record time decreases at record quality increase. You should
