Digital Voice Recorder

EDIC-Mini Tiny+, EDIC-mini Tiny16+

Overlook

Miniature EDIC-Mini Tiny (16) + digital voice recorder (DVR) is intended for
professional recording voice messages into flash-memory. The recordings can be further
uploaded onto the PC. These voice recorders feature really unique characteristics (the
world's smallest size, maximum autonomy, high acoustic sensitivity etc). The recorders
are marketed as personal means of documenting audio information providing protection
against fake records as well as unauthorized access to records.

The EMPlus program located in the built-in memory is used to operate the recorder.
SoundProcessor program is designed to process the transferred records and to facilitate
the conversion of records to text. The programs operate under Windows XP (SP2,
SP3)/Vista/7/8.

Depending on the model, the recorder features extremely small dimensions, weight and
current consumption, long record duration (from 150 hours at sampling rate 8 kHz), wide
frequency and dynamic range. The recorder features built-in clock and calendar, and the
option to start recording at the preset time using timer. Due to the absence of removable
elements the recorder is operational under wide temperature ranges when shaking or
dusted.

The LED indicates operating modes of the device as well as its status.
The recorder is equipped with VAS enabling to compress pauses efficiently in messages
therefore saving considerably the recorder's memory. When uploading records onto the
PC the duration of pauses can be restored in the form of silence or deleted depending on
the settings specified.

The recorder makes it possible to perform timer recording: either daily (with record start
and end time specified) or once (with date and time of record's start and end parameters
specified).

To protect the recorder’s information and setting there is the option to set user's
password. Each record performed by the recorder has a mark of time and date supplied
with “digital signature” to identify the model of the recorder to have performed the
recording and the attempts to modify it.

Depending on the modification, recorders differ in:

• Power source (battery, built-in rechargeable battery or battery + solar battery, external
power supply)

• Built-in memory capacity

• The option to quickly replace the memory
The user can upgrade the recorder's firmware via USB port.

Installing and replacing batteries

Before starting, install the supplied battery. The LED flashes 3 times and it will be on for
about 40 sec. Now the recorder is ready to start operating. When installing, always
observe polarity (marking on the recorder's case corresponds to the one on the battery).
Incorrect installation of battery may lead to malfunction, which is not covered by the
warranty repair.

Supplying power for E71 and E72

For recorders with external power supply connect a DC voltage source (3.7- 6 V) to
contact 1 (minus) and 2 (plus) of the stub coming from the Recorder (Contact 1 is
highlighted in color). In case of a Li-Pol battery being a voltage source, battery charge
can be provided by the current of 100mA using the connection of contacts 2 and 3 (if the
adapter is connected to the recorder and the computer's USB).
