Operating the EMP 2 PRO
Switching on the device
Switch on the device using the key. The EMP 2 PRO starts with the programme
number which was active when the device was last switched off.
Using the 230-Volt mains supply (optional)
After having connected the transformer to your 230-Volt socket, connect the
cable to the power supply socket in the front face of the appliance between the
channel outlets 1 and 2. It should be noted that when the machine is connected
to the transformer connected to the 230-Volt mains supply it will operate from
the mains supply and not the battery.
Activating the editing mode
Only if you switch on the EMP 2 PRO pressing the key, you can activate the
standard programmes (please refer to section entitled “Activating the editing
mode“) and make copies of them in the form of user programmes. However, this
function is only available if the device was not locked beforehand.
Resetting the operating
parameters and deleting
the user programmes
If you wish to delete the user programmes and return the operating time meter,
the cycle meter and the mean stimulation intensity to zero, keep the key on
the left and the key pressed down while switching on the device (please
refer to section entitled “Resetting the operating parameters“).
Programme selection
Use the key to change to the next standard or user programme. However,
this is only possible with an unlocked device. The standard programmes 1 to 20
marked with a ”P“ run initially, followed by the user programmes marked with
an ”U”, if present. When the last programme has been reached, pressing the
key again returns the setting to programme 1 (P1).
Starting stimulation
First, position the electrodes at the desired points of the body and connect
the electrode cables to the electrodes and the device. When the desired pro-
gramme has been selected using the modification key, or the key
increase the intensity (Fig. 2), the two keys may be used to start stimulation. In

schwa-medico Operating Instruction - EMP 2 PRO
6
the display on the right hand-side you find two vertical lines. This means: with
the key both channels will be increased at the same time.
Setting the intensity
You can use the modification keys or the key to set the intensity of
both channels to a pleasant value at any time. The display shows the strength
of current for both channels, which may be varied from 0-100 mA. Intermediate
values are clearly marked by a dash behind the digit. If the electrodes are not
correctly connected to the device, the intensity is returned to zero starting from
a current of 4 mA. If you are in the run-down or pause phase in muscle stimu-
lation programmes and you press one of the modification keys, the working
phase is started directly from the build-up phase.
Symbols on the display
During stimulation, the current intensity status is shown in the middle of the
display by four symbols:
Continuous stimulation or work phase in muscle stimulation. Stimulation is per-
formed at the set intensity.
Build-up phase in muscle stimulation. Intensity is brought up to the set value
from zero. In dynamic stimulation, the intensity of channel 1 is adjusted upwards
to the set value, whereas that of channel 2 is adjusted downwards to zero.
Run-down phase in muscle stimulation. The intensity is brought down from the
set value to zero. In dynamic stimulation, the intensity of channel 2 is adjusted up-
wards to the set value, whereas that of channel 1 is adjusted downwards to zero.
Pause phase in muscle stimulation. Stimulation is performed with 75 % of the
set intensity at a frequency of 3 Hz.
Pause the stimulation
When the sequence number is not flashing, the key may be used to inter-
rupt stimulation. The word “PAUSE“appears on the display. If the pause key is
pressed again, the last intensity set for both channels is restored via a build-up
ramp.
Stopping stimulation
Use the key or modulation keys to stop stimulation at any time. Stimulati-
on stops automatically at the end of a programme.

Locking the programmme
Choose the programme desired for the patient using the key (please refer
to section entitled “Description of programmes“). Lock the device by then pres-
sing the key on the left and also the key. A key appears in the upper
right-hand corner of the display. All device functions apart from stimulation
with the selected programme are now no longer available. Use the same key
combination to unlock the device. A locked device cannot be started in the
editing mode.
Locking the intensity
Choose the programme desired for the patient using the key (please refer to
section entitled “Description of the programmes“). The EMP 2 PRO will be lo-
cked automatically after 10 sec. without increasing or decreasing the intensity.
On the display in the right corner the “P“ symbol will be showed. To unlock the
EMP 2 PRO you have to decrease the intensity.
Activating the editing mode
Please switch on the device while pressing the key. An “E“ on the right-
hand side of the display indicates the editing mode. Then use the key to select
the standard or user programme (Fig. 6) that you wish to edit.
The key is then used to start editing the currently active standard or user pro-
gramme. This is shown by the fact that the “P“ or “U“ symbol before the pro-
gramme number changes to an“E“.
Editing standard or
user programmes
The parameters of each programme are used as the starting value. Press the
key to jump to the next parameter or to save the values.
Use the key to interrupt the editing process at any time without saving the
altered parameters.
Various parameters may be processed, depending on the type of programme. If
not indicated otherwise, the frequency and the pulse width apply for both chan-
nels. Use the modification keys to adjust the values. If you keep the keys pressed
down, counting up or down of the parameter is automatically continued.

Deleting the user
programmes
To delete all user programmes, keep the key and the key on the left
pressed down when switching on the device. This will also return all operating
parameters to zero.
Description of parameters
These values are used to check the patient’s stimulation behaviour. The fol-
lowing information are reported by the EMP 2 PRO: The stimulation time (Fig.
13) is the total time during which stimulation was carried out with the device.
The cycles (Fig. 14) mark how often the device was switched on and concomi-
tantly used for stimulation. The mean stimulation intensity (Fig. 15) is the mean
value of all values for current set by the patient. This information is registered
separately for the two channels. The values are updated every minute during
stimulation. However, only intensities above 4 mA are considered.
Calling up the parameters
Press the key on the left and the key at the same time. The stimulation
time in hours and minutes is first shown in the upper part of the display. The
number of cycles is shown in the lower part of the display.
After pressing the key, the mean stimulation intensity for channel 1 is
shown in the lower left part of the display, that for channel 2 in the lower
right part.
Resetting the operating
parameters
To reset all the described values to zero, keep the key on the left and the
key pressed down when switching on the device. Please be aware that all
user programmes are also deleted.
Switching off the device
Use the key to switch off the device. If the battery voltage has fallen below
a critical value, or if no key is pressed for two minutes outside stimulation, the
device switches itself off automatically. This is signalled by a beep.

Description: Basically, the device works like in the muscle mode but without
working and break times. During the build-up phase intensity is increased up to
the set value. The run-down phase is following immediately, decreasing intensity
back to zero. The channels of the EMP 2 PRO work alternately, i. e. when channel
1 has reached its maximum intensity; the intensity of channel 2 is zero and vice
versa. There is a convenient massage effect owing to the dynamic stimulation
when placing the electrodes next to each other on the painful area.

Programme 7 Epicondylites
Type of stimulation: Modulation
Parameters: Frequency minimal = 2 Hz => Pulse width = 200 µs
Frequency maximal = 80 Hz => Pulse width = 100 µs
Treatment time during modulation = 7,5 s
Treatment time total = 30 min
Symbol showing on display during stimulation:
Ramp up: Ramp down:
Description: In the build-up phase, frequency is increased within a few se-
conds in individual steps, starting from minimum and reaching maximum fre-
quency, the pulse width being adapted accordingly. This is followed by a run-
down phase in which the intensity is regulated back down to the minimum.

Rubber electrodes
Technical Data
Compound: silicone-carbon
Durability: approx. 12 months
Colour: black
Manufacturer: Pierenkemper GmbH, Germany
Application
Spread 2-3 drops of schwa-medico electrode gel evenly over the flat side of
the electrode. The electrode gel improves the conductivity of the electrode.
Place the electrodes on the relevant skin areas and secure the electrodes with
a tape strip. Do not apply to broken skin!
Because conductivity of the electrodes slowly decreases after approx. 6 months
of use, replace electrodes after approx. 12 months of intensive use.
Cleaning
Clean electrode surface with water and soap or appropriate disinfectant (e. g.
alcohol 90 %) after every use.
