Preface
The Operang Instrucons are directed at healthcare professionals physicians, who
are familiar with the handling and of low level laser systems.
The laser shower PowerTwin21 is a therapy device for the low level laser therapy
of large body areas. Low level laser therapy belongs to the eld of complementary
therapy.
Advice
Please read the Operang Instrucons carefully before using the device. The
Operang Instrucons should always be kept at the place where the low level laser
system is employed.
Users must be able to reduce the risks and complicaons that are associated with
the use of low level laser systems by taking the appropriate acon.

the soware status of the unit.
This screen appears aer the laser unit has been turned
on once the boong process is nished. The second line
shows the wavelength and the maximum CW output. The
loudspeaker icon indicates the sound is acvated.
Inial seng. The sengs which were used last and
the current therapy parameters (laser power, therapy
program, energy dose rate) are displayed. Factory seng
when delivering is: 50 mW * Mul * 10 min (15 J/LD)
A value that appears inverted can be changed with the “+”
and “–” keys. On this screen the laser power level can be
altered. Pressing the SET key saves the respecve value.

5. Operaon
5.1 Unlocking
Insert the key pin into the red connector at the boom of the housing of
the laser shower PowerTwin21 (● page 4, g. 1/7). The adapter ring for the
laser shower or laser comb must be plugged in (● secon 9, “Replacing the
Adapters”, page 15, resp. page 4, gures 2/10+11).
The PowerTwin21 cannot be operated without the adapter ring. Only the
power supply unit AC/DC adapter type FW7555M/12 which was shipped with
the unit must be used.
Connect AC adapter with adapter plug
The power supply unit (AC adapter) and the PowerTwin21 are connected with
an intermediate plug. Should you wish to remove the power supply unit from
the laser shower PowerTwin21, please proceed as follows:
 Slightly push back the locking device (black sleeve)
at the plug, and pull the two plugs apart.
Aenon!
The plug-in connecon is a push-pull locking system. Hold the plug-in
connecon only by the sleeves with the arrows, as illustrated. Never twist
the plugs or pull at the back ends of the plug.
 If you reconnect the PowerTwin21 with the AC adapter, make sure you
observe the direcon of the arrows on the plugs.
5.2 Connect AC Adapter to the power supply
Connect the AC adapter to the mains (100–240 V~). A correct connecon is
indicated by a green control light at the AC adapter.
5.3 Inial sengs aer boong
Aer switching the device on, the output data of your lasersystem (wavelength
and max. output) are indicated in the second line.

5.4 Further inial sengs
You can turn the display (right-handed/le-handed users) with the “+”key (paghe
4, g. 1/3). With the key “laser” you can turn o the fans (Our recommendaon:
only work with acvated fans).
5.5 Display of saved therapy parameters
By pressing the “SET” key, the currently set parameters (inial seng) of the
unit are displayed. With rst use you'll be indicated the following inial sengs:
The maximum output of 50 mW, the operaon mode Mul and an energy dose
of 15 J/LD (LD = laser diode) are preset when operated for the rst me.
Following this the laser power values selected and stored previously will be
displayed, as well as the therapy program and therapy dose used the last me.
Changing the laser parameters:
 Chapter 6.0 “Changing of laser parameters” (page 10 )

6. Changing of laser parameters
Having pressed the SET key, the output value is blinking as highlighted in below
gure. Changes can be made by pressing “+/-“-keys accordingly. Sengs can be
done from 10% to 100 % (in regard to the maximum value) in increments of 10%.
By pressing the SET key again, the selected value is conrmed and stored. The
display changes, showing the following informaon.
The therapy program can be changed with the “+” and “–” (page 4, g. 1/3) keys
and saved with the SET key.
The seng opons are:
● CW ● Mulfrequency ● Alphafrequency ● Nogier-Frequencies A-G, L
● Nogier-Frequencies pot. A‘-G‘ ● Bahr-Frequencies 1-7 ● Reininger-
Frequencies ● free programmable frequencies 1-9.999 Hz.
New frequencies (purchase oponal): ● Bahr+ , ● Solfeggio-frequencies
● FI-bands (FI: Regeneraon, Pain, Interference, Trauma, Inner Center, Detox, In-
fecon, Bones, Nerve, Transcranium, Psyche/Vegetavum, Lymph, Trigger Points)
● Sweeps (Sweep: Alpha, Purr, Beta, Theta, Delta) ● Cranio
