Preface
The Operang Instrucons 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 Operang Instrucons carefully before using the device. The
Operang Instrucons should always be kept at the place where the low level laser
system is employed.
Users must be able to reduce the risks and complicaons that are associated with
the use of low level laser systems by taking the appropriate acon.

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 respecve value.

5. Operaon
5.1 Unlocking
Insert the key pin into the red connector at the boom 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 (● secon 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.
Aenon!
The plug-in connecon is a push-pull locking system. Hold the plug-in
connecon 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 direcon 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 connecon is
indicated by a green control light at the AC adapter.
5.3 Inial sengs aer boong
Aer switching the device on, the output data of your lasersystem (wavelength
and max. output) are indicated in the second line.

5.4 Further inial sengs
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 recommendaon:
only work with acvated fans).
5.5 Display of saved therapy parameters
By pressing the “SET” key, the currently set parameters (inial seng) of the
unit are displayed. With rst use you'll be indicated the following inial sengs:
The maximum output of 50 mW, the operaon 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.

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. Sengs 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 conrmed and stored. The
display changes, showing the following informaon.
The therapy program can be changed with the “+” and “–” (page 4, g. 1/3) keys
and saved with the SET key.
The seng opons are:
● CW ● Mulfrequency ● 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 oponal): ● Bahr+
,
● Solfeggio-frequencies
● FI-bands (FI: Regeneraon, Pain, Interference, Trauma, Inner Center, Detox, In-
fecon, Bones, Nerve, Transcranium, Psyche/Vegetavum, Lymph, Trigger Points)
● Sweeps (Sweep: Alpha, Purr, Beta, Theta, Delta) ● Cranio
