DEFINITIONS
Amplitude modulation (Am) is a periodic variation of stimuli amplitude
(as well as stimuli Energy). Am is defined as the ratio of the time the
device is sending pulses with preset Energy to that with minimal En-
ergy. For example, the ‘3:1’Am setting indicates that the device is
transmitting stimuli with preset Energy for 3 seconds and then with
Energy = 1 for 1 second. Amplitude modulation manifests itself as
strengthening and weakening the specific sensations with a set period.
Dose is a signal to the operator that the rate of skin impedance change has
sufficiently reduced.
Dosed Stimulation determines the type of dosing provided by the device.
When the Dosed Stimulation is switched ON, the stimulation time for a
zone is determined automatically. When the Dosed Stimulation is
switched OFF, the zones to be treated, stimulation time for each zone and
time of the whole session are determined by the therapist.
Energy is a parameter determining strength of every stimulus. The Energy
influences stimulus amplitude and strength of stimulation sensation.
The higher the Energy, the stronger the specific sensations felt by the
patient.
Electrodes are сutaneous electrodes (built-in electrode and add-on electrodes)
that are applied directly to patient’s skin for electrical stimulation.
Frequency (F) is a number of stimuli (or stimuli bursts) per second,
measured in Hertz (Hz). When Frequency changes the strength and
'volume' of sensations also change.
Frequency modulation (Fm) is a periodical change of stimuli Frequency
from initial to final Frequency value and back. The sensations are
similar to those accompanying manual Frequency change.
Impedance is determined by the combined physical characteristics of the
skin, defining its ability to absorb the Energy generated by the device.
Stimulus is a single two-phase output pulse.

When the dose is reached, all the LEDs flash on shortly and a two-
tone beep sounds.
(Optional) The ‘D2’ mode is intended for searching skin areas with
maximal reaction in a labile mode. If the current reaction exceeds the pre-
vious maximum, this is indicated by a clicking sound. The current reac-
tion to the initial reaction ratio is indicated by LEDs flashing on:

ATTENTION! In fact there is a double indication: a relative val-
ue of current reaction to initial one –by LEDs and sounds, and an
absolute maximum of reaction –by clicks.
4.2.7 To set the AM mode, press the ‘ ’ button (sequence of single
taps) until the ‘Am’ LED starts blinking. While the ‘Am’ LED is blinking,
press the ‘ ’ button to switch the mode on, and press the ‘ ’ button to
switch the mode off. The mode switching on is accompanied by an ascend-
ing two-tone beep, the switching off –by a descending two-tone beep.
In the Amplitude modulation mode the stimulation is intermittent:
3 sec –stimulation, 1 sec –pause. The ‘ ’ LED brightness is changing.
4.2.8 To set the FM mode press the ‘ ’ button (sequence of single
taps) until the ‘Fm’ LED starts blinking. While the ‘Fm’ LED is blinking,
press the ‘’ button to switch the mode on, and press the ‘ ’ button to
switch the mode off. The mode switching on is accompanied by an ascend-
ing two-tone beep, the mode switching off –by a descending two-tone beep.
In the Frequency modulation mode the stimulation frequency is con-
tinuously changing from 30 to 120 Hz and back. The ‘ ’ LED brightness
is changing depending on the pulse frequency.
4.2.9 To select one of four stimulation frequencies (14, 60, 90 or
340 Hz), press the ‘ ’ button (sequence of single taps) until the ‘F’LED
starts blinking. To select a frequency press the ‘ ’ or ‘ ’ button (se-
quence of single taps) while the ‘F’LED is blinking. The frequency selec-
tion is accompanied by short beeps:
14 Hz –one beep;
60 Hz –two beeps;

90 Hz –three beeps;
340 Hz –four beeps.
Once a new frequency is set, the ‘ ’ LED brightness changes.
When the ‘Fm’ mode is on, the frequency set in the ‘F’ mode is disre-
garded and the frequency selection is blocked. When the ‘Fm’ mode is
switched off, the previously used frequency is set.
4.2.10 Some modes may be used together: ‘D+Am’ (at any frequen-
cy), ‘D+Fm’, ‘D+Am+Fm’, ‘Am+Fm’. For this purpose, switch on the
required modes sequentially.
(Optional) For user’s convenience SCENAR has two pre-installed
modes (Presets).
To enter the preselection mode press the ‘ ’ button (sequence of
single taps) until the ‘rolling light’ (sequential short flashes of the LEDs
during 2 seconds). In this mode you can select one of two presets by press-
ing the ‘’ button. Selected and set mode is indicated by LEDs and sound:
Preset 1(single beep, ‘Am’ and ‘Fm’ LEDs go ON): frequency
modulation and amplitude modulation are switched ON.
Preset 2 (double beep, ‘D’ and ‘F’ LEDs go ON): the number of
pulses in a batch and the gap between the pulses are controlled
automatically at the 90 Hz frequency.
While any Preset is ON, the switching to another mode by pressing
the ‘ ’ button will be locked and LEDs will be glowing according to the
active Preset. Turn the Preset OFF to return to regular operation mode.
To turn the Preset OFF press the ‘’ button, while the LEDs are
glowing according to the active Preset. When the Preset is turned OFF, the
energy level will be saved, all other parameters will be set to default
(‘Fm’, ‘Am’ and ‘D’ are turned OFF, the frequency is 60 Hz).
(Optional) For user’s convenience SCENAR provides the quick access
to the Preset 2. For this purpose press the ‘ ’ and ‘ ’ buttons simultane-
ously.
4.2.11 Enabling/disabling sounds:
to enable sounds, press the ‘ ’ and ‘ ’ buttons simultaneously
(the SCENAR device emits a beep);
to disable sounds, press the ‘ ’ and ‘ ’ buttons simultaneously
(no sounds).
4.2.12 (Optional) To lock/unlock a keyboard press and hold the ‘ ’
and ‘ ’ buttons (for about 2 sec) until the SCENAR device emits a two-
tone descending/ascending beep.
If the SCENAR device switches off automatically, the keyboard will
be unlocked when the SCENAR device is switched on next time.
