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 theEdic-mini LCD series are professional devices
intended for making high quality recording of voice messages into built-in
flash-memory. You can playback recorded messages using
headphone and save them in your computer as standard audio files.

Voice recorders feature extremely small dimensions and weight, long

record time (varies with the model up to 600 hours), standby
operation (up to 1000 hours), and highly sensitive built-in microphone
with a wide dynamic range. Due to the absence of moving parts, the
DVR functions even under the conditions of strong vibration, dustiness,

and low temperatures.
The supplied USB adapter provides high-speed data exchange

between the DVR and the computer (1.5 Mb). The software supplied
on the CD makes it possible to save the recorded messages as
standard audio files, set the DVR parameters, and 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 a built-in timer and a real time clock.

The DVR has a Voice Activating System (VAS) which effectively

compresses pauses in messages therefore increasing the actual
recording time. The pause length can be restored at further file

processing with the software supplied.

The DVR features a SuperExtraLongPlay mode (modified 2-bit

ADPCM, sample rate 4 kHz, 8 Kbit/s), which increases the recording time

twice as much as regards the data in the table.

- Supply voltage: 2.7-3.2 V;

- Operating temperature: -20- +50°C (68-122F);

- Maximum bandwidth:

- at playback on PC: 100-6000 Hz;

- at playback through the earphone: 100-3800 Hz;

- Sample rate: 16000, 8000, 4000 Hz;

- Codec capacity: 16 bits;

- Signal/noise ratio: 72 dB;

- Quality, formats and density of data record:

Without compression (linear), sampling rate is 16 kHz, 256 Kbit/s, k=16
Without compression (linear), sampling rate is 8 kHz, 128 Kbit/s, k=8
Without compression (linear), sampling rate is 4 kHz, 64 Kbit/s, k=4
Logarithmic compression, sampling rate is 16 kHz, 128 Kbit/s, k=8
Logarithmic compression, sampling rate is 8 kHz, 64 Kbit/s, k=4
Logarithmic compression, sampling rate is 4 kHz, 32 Kbit/s, k=2
Modified 4-bit ADPCM, sampling rate is 8 kHz, 32 Kbit/s, k=2
Modified 2-bit ADPCM, sampling rate is 8 kHz, 16 Kbit/s, k=1
Modified 4-bit ADPCM, sampling rate is 4 kHz, 16 Kbit/s, k=1
Modified 2-bit ADPCM, sampling rate is 4 kHz, 8 Kbit/s, k=0.5

where k is the coefficient, showing how many times the maximum

recording time decreases when record quality increases.

- Automated Voice Activation System (VAS);

- Antialiasing median program filter;

- Recording in the linear and circular modes (in the circular mode, the
buffer size is set in per cent of total memory size);

- Built-in microphone sensitivity: 7-9 m.;

- 8 user sets of record parameters (profiles);

- Random record delete;

- Real time clock;

- Battery charge indicator;

- USB interface with a PC, data exchange speed: 1.5 Mb;

- Reliable data storage in flash-memory: over 10 years;

- Consumption in Standby mode with the indicator on: 0.14 mA;

- Consumption in Standby mode with the indicator off: 0.016 mA.

With the VAS on and the signal below equils the threshold,
consumption does not exceed 0.2 ma. At
playback the consumption is 5-7 m A in all modes.

DVR Operating

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 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 checked 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).

If the battery is inserted properly, the DVR will execute self-testing,
and you will see the total memory capacity and firmware version on
the display, then all the LCD elements will be indicated for a
moment. After that you will see the following information on the
display:

- In the symbol line battery charge indicator and mode symbol
(Stop mode);

- In the numeric line the current time (hours and minutes), the
separator blinks at a 2-second interval. (Fig. 1)

The DVR is in the Standby mode and ready to work. If let without a

push-button activity for a minute, the DVR goes to Sleeping

mode and the LCD display goes off. Push the joystick up to switch back it

on.

Battery replacement

Battery charge indicator shows how much battery life is left.

If the battery is fully charged, the battery indicator border and three
lines inside will be shown on the display

If there is only the battery border on the display, it means that the
battery is discharged and should be replaced. When the battery is

discharged, the DVR does not react to the pressing or pushing of

buttons, and the display remains off.

You can replace the battery without switching off the DVR. At that it
can work for some seconds without the battery. Thus, if the battery
is replaced fast enough, the built-in real time clock does not reset.

Earphone and remote control connection

The headphone and remote control can be connected through the
headphone connector on the side part of the case. You should fully
insert the headphone plug into the connector.

Operating Modes

You can select a mode with the push-button manipulator
(joystick) in accordance with the diagram. (See the control chart at
the end of the manual).

If it is left without a push-button activity for a minute, the DVR switches
to the Energy-saving mode and the LCD display goes off.
Push the button up to switch it back on.

Record mode (REC)

To start the Record mode, press the button once or twice, depending

on settings made when connecting to the PC.

On the display you will see:
