Overlook

1. Purpose

Voice recorders of the Edic-mini Tiny (16) + series are professional devices
intended for making high quality record of vo ice messages into built­in 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 sensitiv ity 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 transfer red records and t o
facilitate the conversion of records to text. The programs operate under Windows XP
(SP2, SP3)/Vista/7/8/10.

2. Features

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,

• built-in clock and calendar,

• the option to start recording at the preset time using timer,

• due to the absence of rem ova bl e ele me nt s the recorder is operational

under wi de temperature ranges when

shaking or d usted,

• the LED indicates operating modes of the dev ice as well as its stat us.

3. Short description

The recorder is equipped with Voice activation system (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 t he 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 speci fied).

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 after uploa di ng to PC.

The user may set tabs while recording. These markers will be visible by
SoundProcessor program on PC. Using them it is easy and quick to find important
moments in long records.

Depending on the m odificati on, recorders differ in:

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

• Built-in memory capacity

• The option to quic k ly replace the memory

The user can upgrade the recorder's fir m ware via USB port.

5. Recording Duration

Recording duration depends on the type and quality of the battery in use, its charge
level, and the record mode specified.
It is recommended not to use mode 22kHz for recording on to recorders with battery,
because operation in this mode requires very large currents. Often batteries are not
designed for such currents and the recorder records much less time than the one
specified. Accordingly recording time in the mode 22kHz depends greatly on the battery
quality. If this mode is needed, please use batteries which designed to work not with
watches but with technique. Battery 2016 brands that we recommend – Duracell, Sony
Energizer, Renata, Varta.

Operatio n the Recorder

6. Installing and replacing batteries

Note! Only for recorders with replaceable battery (B-type models)
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 war ranty repai r.

7. Supplying power for E71,E72,E84

Switch the recorder to OFF position and then connect DC power supply (3.6-6V) to
pins 1 (minus, gold colored wire) and 2 (plus, red colored wire) of the cable coming
from the Recorder. If the voltage source is represented by a Li-Pol battery, the
connected pins 2 and 3 (green colored wire) of the cable can provide battery
charge with the current of 100mA (provided the recorder is connected to the adapter,
and the adapter is connected to the USB).

8. Start and Stop Recording

To start recording, set the Switch to «On». The LED flashes five times, and the recorder
starts recording. During recording, the LED is flashing, the number of flashes
indicating:

Number of fl ashes

Battery charge level

(1st series)

Free memory capac ity

(2nd s eries)

1

80 - 100%

75 - 100%

2

20 - 80%

50 - 75%

3

2 - 20%

25 - 50%

4

1 - 25%

The interval between the first and second series of flashes is approximately 4 seconds,
and between the second and first is about 8 seconds. Note that in battery recorders the
first series of flashes shows battery charge at the t ime the recorder has been ac tivated
and is not controll ed dur ing recording.

To stop recording, shift the Switch to «Off» position. The LED flashes once for 10-12
seconds and the recorder stops recording.

Attention:

• Avoid using the recorder with nearly discharged battery, Otherwise it may turn

off at the wrong moment.

• The higher the record's sampling rate, the more energy is consumed by the

recorder. At the frequency of 22 kHz the consumption is almost twice higher
than at 8 kHz, and for the recorders with batteries the autonomy is down by
more t han three times.

• Fast switching during recording

(On → Off → On) puts the tab which is visible in the Sound Processor
program. Thus it is possible to mark the desired parts of records and then
quickly find them.

• Fast switching when the recorder is off

(Off → On → Off) shows battery charge level and free memory capacity
through flashing of LE D. For thi s in dicati on, see «Start an d S top R ecording»

9. Playing Back and Uploading to the PC

Use EMPlus program to play back and upload records onto the PC as well as to configure
your recorder. SoundProcessor program is designed to process the transferred
records.

Both programs including the instructions are in the built-in memory
of the recorder and operate under OS Windows XP (SP2, SP3),
Windows Vista/7/8/10. Newer versions are always available on the website
http://www.ts-market.com

Note! For recorders with replaceable battery (B-type models) the battery should
be inserted. Otherwise the Recorder may not be detected by computer.

1. Turn the Recorder to OFF position and wait until the LED turns off. Connect

USB adapter to the recorder, then to the PC. Red and green LEDs blink
briefly on the adapter. Windows recognizes a new removable drive. It is
very important to observe the connection sequence: Recorder→USB
adapter→PC

2. Run the EMPlus program from the recognized removable drive. The content
of the recorder is on the lef t side of the window. Select the desired record.

3. To play back select the record and press the Play button at the
bottom of the left panel. To upload right click on the selected record
and choose «Copy to PC» from the context menu. The record will
be converted to WAV to be displayed at the right pane l. You can also
drag and drop the selected record from the left panel t o the right one.

• Do not disconnect the recorder while performing any operations in the EMPlus
program. This can cause data corruption (during such operations the recorder's
LED is flas hing).

• When the recorder is connected to the PC, recording is unavailable. If the
recorder is in record mode, recording stops after connecting to USB port of
the PC.

Observe disconnection order: first disconnect USB adapter from the PC, then
recorder from US B adapter!

9.1. Uploading from the B70 recorder

1. F rom page of the B70 recorder on our web-site www.ts-market.com, from section

Using All Func tions of Recorder

10. Setting Microphone Amplification for Tiny16+

The recorder provides the option to adjust amplification of the microphone's signal (from
0 dB to +40 dB). B oth fixed amplification and Automatic Gain Control can be set. AGC

enables it to automatically adjust amplification according to the sound level. That makes
it possible to perfectly record very loud sounds and amplify silent ones. Choose
suitable for you AG C level from pre-installed:

• amplification without AGC;

• AGC1 – f or recording in a quiet room;

• AGC2 - for recording in a noisy room;

• AGC3 - for recording from large distances;

• AGC4 - for recording in a noisy lar ge roo m;

• AGC5 - for recording on a noisy street.

11. Timers

The recorder has two timers: Daily and Once. Timers enable recording to start
automatically, without user’s control.

1. When setting Once Timer you need to specify the record’s start and end time
and date. For example, «start 31.12.2013 23:00 stop 03.01.2014 10:00» - with
these settings your recorder will record from 23:00 on the 31st of December
2013 until 10:00 of January 3, 2014. However while configuring you should
take into account the capabilities of your recorder, i.e. whether it’s free memory
is enough to perform the operation. To check this see «free memory « in
EMPlus and continuous operation ti me in Appendix 1.

2. When configuring Daily Timer you need to set record's start and end time.
For example «start 09:20 stop 13:05» - with these settings the recorder starts
recording every day at 9:20 and stops recording at 13:05. Recording will be
carried out as long as the recorder has free memory, enough charge and as
long as the timer is on.

3. You can use both timers simultaneously, but you should take into account that
timer's operation times must not overlap or intersect.

Timer recording by can be stopped by shifting the recorder's switch to ON, then

again to OFF position.

If timer is on, you don't have to enable recording using switch
(don't forget to synchroniz e the record er's ti me with the PC tim e).

12. Voice Activation System (VAS)

Voice Activation System (VAS) can significantly (up to 100 times if properly configured)
reduce both memory consumption and energy consumption from the power source.
The principle of VAS is as follo ws: after the user starts recording,
the recorder sta rts trac ing signal fro m the microphone.
If the signal is less than the one specified in settings (VAS level), it is not the sound
from the microphone that is stored in memory, but only the time value during which the
threshold hasn't been ex ceed ed.

When signal level exceeds the preset threshold, recording of sound into memory starts.
When the signal from the microphone is less than the preset threshold, after some time
(VAS time) the recorder stops recording sound into memory and only saves silence
duration. That conti nues u ntil r ecording stops.

In case of signal level exceeding the preset threshold, indication while recording
with VAS is the same as during standard recording (two series of flashes). I n ca se
of signal below threshold (silence), there is constant faint glow of LED. When
uploading record onto the PC, you can specify the operations with pauses: save
them in the file uploaded or not. If you save pauses, the duration of the resulting
record will correspond to the actual one, and the fragments when the signal was below
threshold will be played back silent. If the pauses are not saved, then the resulting
record will consist of recorded parts only (signal exceeds the threshold). These parts
will be played one after another without int erruption.

13. Configuring VAS

Voic e Ac tivation System (VAS) is config ured in the EMPlus program
by changing two parameters:

1. VAS threshold level and VAS time. VAS level can be adjusted from
0 to -55 dB. 0 dB corresponds to very low sensitivity (the device records only
very loud sounds) and the value of -55 dB to very high sensitivit y (the slightest

rustle is enough for the recorder to start recording). The best of VAS is
achieved experimentally. You can start by setting VAS level at - 20 dB (after
you have changed the settings, do not forget to press the button «Apply
changes to the

Recorder»). After disconnecting the recorder off the PC enable

recording and place it in the conditions similar to the planned recording (for
example, lecture in a classroom). With the level of VAS properly configured, after
the desired signal, the recorder switches to record mode which will be indicated
by a LED flashing. If desired signal stops, and the VAS time is up, the recorder
switches to S ignal Standby mode.

• If in case of silence, the recorder does not go to Signal Standby Mode and

continues recording, VAS level is to be changed to be closer to zero (if it was -20

dB, now it sho uld be set at -17 dB) .

• If when desired signal appears the recorder does not go to Record Mode, the level of

VAS

should be changed to be closer to -55 dB (if it was - 20 dB, now you need to set it

at - 25 dB).

2. VAS time is adjusted from 1 to 15 seconds. If you set VAS time at 1 sec ond,
the record within the file will be divided into many pieces with the pauses in
conversation for more than 1 second. If you set 15 seconds, after any
knocking the recorder will continue recording silence for 15 seconds. The
best of VAS is achie ved experimentally, but for most cases the value of
7 seconds is enough.

If VAS operates together with timers, you don't have to enable recording as it
starts automatically with the timer, providing that you synchronized the
recorder's time with the time on the PC.

14. Circular Recording

The Recorder has the option of circular recording. In the EMPlus program you can
devote a part of the recorder's memory (or the whole memory) to circular recording.
After there is no more free memory, the recorder begins to record new data over old
ones. The volume of the memory specified determines the duration of the resulting

circular record.

15. Charging and Battery Maintenance

Note! Only for recorders with rechargeable battery (A and S-type models)
The battery starts charging automatically when you connect the recorder to the USB-

port of the computer. Full charging takes 3 hours (while charging LED is flashing
gradually with the interval of 5 seconds). With maximum charging LED will continuously
and smoothly change its brightness. The user can recharge the rechargeable battery via
power source with standard USB- output (5 V), during which the LED is permanently on
and one can assess the process according to the charging time only (3 hours).

Do not leave the rechargeable battery discharged. Recharge it at least once a month,
even if you don't use the recorder. Failure of the battery due to customer's fault is not
cover ed by the war ra nt y.

Attention!

In firmwa re versions 1.14 for Tiny+ and 1.15 for Tiny16+ after memory filling, recorder
does not turn to Standby mode. That may lead to deep battery discharge and its
damage.

See your firmware version in EM PLUS program on the bottom line of the main menu
(for instance FW: 1.14).

In cas e of battery di scharge, fulfill the following steps as soo n as pos sible:

1. Clear the memory

2. Charge the bat tery

If you could not charge the bat tery, follow thes e steps:

1. Connect USB adapter to PC

2. Turn the switch to O n position

3. Connect recorder to th e P C

4. Hold d own the Reset but t on wi thi n 10 sec on d

5. After 10 minutes, with recorder connected to PC, turn the switch to Off position
and th en pres s Reset button onc e.

6. Leave t he recorder to charge for 3 hours

This problem will be solved in next firmware upgrade, which you will be able to
downl oad fr om our we b-site www.ts-market.com
