Components Guide
Electrodes
Model EX715Ag employs a new technology of manufacturing
of removable electrodes. The electrodes are made of silver of
the 925th standard, which preserves the natural structure of
silver. This provides additional healing effect and better
penetration of the acting signal during treatment.

15
Indication
Graphic gray-shade OLED display shows action modes, action
energy, activity of the area being acted upon, dosage, time of
action upon the certain area and full time of action, menu,
and battery charge level. Additional LED and sound
indication allows you to evaluate if the area you have chosen
for action is the appropriate one, activation of dynamic
adaptation block and proper contact of the electrodes with
skin.
Control
You can operate the device with four buttons. They allow you
to regulate the action energy level, set the necessary action
mode and work with on-screen menu. All other settings are
performed automatically.

16
Casing
The device is encased in “SMART” series casing. Waterproof
keyboard and sealants make disinfection and cleaning of the
device easy. The casing is made of shockproof (3 mm thick)
ABS plastic.
Accessories
Leather case
The case is made of high-quality genuine leather. It protects
the device from damage, dust and dirt during transportation
and storage.
Gold Electrodes
For model EX715Ag you can additionally order electrodes
made of gold of the 958th or 999.9th standard, hardened and
structured according to special technology. Gold provides the
best conductivity of electrodes which, in its turn, guarantees
deepest and most effective action. Gold is a biologically inert
metal for the human body.
Gold electrodes can be easily installed instead of silver ones.

17
Remote Electrode Probes
You can attach remote electrodes probes to the device.
Remote probe with electrodes made of stainless steel is
intended for action upon small areas.
Remote probe with silver electrodes is mainly used for
treatment of children, especially new-born babies, and for
cosmetic purposes.

18
Remote probe with silver electrodes for vaginal action is used
for treatment of diseases of genital organs and neighbouring
organs and systems.
Remote probe with silver electrodes for rectal action is used
for treatment of diseases of rectum, urogenital system,
pathological conditions of small pelvis, etc.
Arrangement and Operation
The device consists of a casing and removable electrodes.
Model EX715Ag has a special construction of removable silver
electrodes. It allows taking the electrodes out of the casing
(which makes disinfection and cleaning easier) and replacing
the silver electrodes with gold ones. The rounded part is
convenient for acting upon hard-to-reach or small areas (e.g.
on the face). The flat part on the under side is the main one
for treatment.
Visual indicators and operating controls are placed on the
upper cover of the plastic casing:

19
A connector allowing attachment of remote electrode probe
is placed at the end of the casing.
Indicators C, D and R
Indicators placed under the keyboard provide additional
monitoring during action. Flashing LEDs make action control
easier if the display of the device is out of sight.
Cis a LED indication of the contact of electrodes with skin. It
lights up when the electrodes touch the skin and is
continuously on until the electrodes are taken off the skin.
The “C” indicator may not light up in some medical cases or
conditions of skin and when acting upon hairy areas of the
body. In this case, moisten the skin or hair with a cotton wool
slightly wet with water.
Dis a LED indication of “dynamic adaptation” mode.
Indicator “D” lights up and is continuously on at activation of
the “dynamic adaptation” mode.

20
The dynamic adaptation block is activated in mode S1. It
allows you to automatically regulate actions and pauses
between actions, without removing the electrodes from skin.
It is necessary for prolonged actions, when eliminating pain,
or when the patient is lying on the electrodes, and in many
other cases.
At activation of the “dynamic adaptation” mode, indicator “D”
lights up and is continuously on while the “C” indicator is
alternately going “on” and “off”. The “C” indicator going “on”
means action and going “off” means pause between actions.
This function is completely automated.
Ris a LED indication of body reaction. Frequency of flashing is
proportional to the body reaction.
During treatment indicator “R” provides additional indication
allowing you to control the action.
Getting Started
