Preface
One of our prime objectives as a Swiss company is the development and manufacturing of
precise and reliable products for physical therapy based on years of experience. Some of
our products are well known and utilized internationally. As a small company we can afford
to keep in touch with our customers who often contribute to new developments.
May your work with the F-SCAN2be beneficial for you and for your clients.
Introduction
The FREQUENCY SYNTHESIZER F-SCAN2has been optimized for stationary as well as
‘out of office’ use by medical professionals and healing practitioners. The device advances
and expands the range of applications originally defined by its predecessor, the F-SCAN.
The units touch screen display can be tilted within 90 degrees. Itresponds quickly to
commands and is easy to operate.
The device generates precise SINE wave signals (DC-OFFSET) and SQUARE wave
signals (FULL WAVE or DC-OFFSET) and feeds them to a single OUTPUT connector.
A separate POWER PORT provides amplified signals synchronized with the signals
available on the OUTPUT port for use with light or magnetic coil adapters, etc.
The AMPLITUDE of the sine wave signals is preset. The amplitude of the square wave
signals can be individually adjusted in a broad range.
A TIMER can be assigned individually to each frequency or as a global function.
The special application modes “WOBBLE” and “PULSE” are global functions. If enabled,
they affect all frequencies used in an application.
A “Sweep To Next” mode allows a sweep between two adjacent values in a sequence of
frequencies.
The unique DIRP (Dual Integration Resonance Procedure) can be used to SCAN FOR
RESONANT FREQUENCIES in the unit’s frequency band between 1Hz and
15,000,000Hz. The sensitivity of the analysis function can be adjusted from the default
value of “L”=Low to “M”=Medium or “H”=High.
A WIDE BAND SWEEP can be performed.
A ZAPPER session is preprogrammed and can be started with a touch on the ZAPPER
icon.
All functions are controlled by a microprocessor. The built-in permanent (non volatile)
memory contains a list of the 235 pathogens identified by Dr. Hulda R. CLARK (called
CLARK table in this document) with their typical frequencies as well as a list of 348 low
frequency applications (called RIFE table in this document).

Product highlights
•The F-SCAN2is operated by a backlit monochrome LCD touch screen display of 320 x 240
pixels. Its viewing angle can be adjusted to the users comfort within 90 degrees. Touch
commands are executed instantaneously which reduces setup times.
•A single OUTPUT port on the right side of the device can be programmed and provides sine-,
square- and square 5Volt- signals.
•Square wave signals can be delivered FULL WAVE or DC-OFFSET – selectable with a switch.
Their amplitude can be adjusted with a potentiometer between 0Vpp and 27Vpp or 13.5Vpp.
•A POWER PORT on the rear side of the device provides amplified square wave signals
synchronized with those available on the OUTPUT port for use with light or magnetic coil
adapters, etc. The output range is from 0.1Hz to 1MHz with a preset amplitude of 14Vpp.
•Two frequency tables are permanently stored and items can be selected with a touch on an
alpha sorted name table and transferred to the operating memory.
•Frequency values between 0.1Hz and 3,000,000Hz can be set for square wave signals and
between 0.1Hz and 15,000,000Hz for sine wave signals.
•Integrated adjustable common and multiple individual TIMER.
•‘SWEEP’ – mode, for wide band application of frequencies.
•‘Sweep To Next’ – mode,allows to sweep between any two values of a frequency sequence.
•User accessible memory provides a capacity to store 50 data blocks permanently (until an
overwrite). Each data block can be comprised of up to 50 frequencies (with one decimal, if
required), their assigned signal form and the ‘Sweep To Next’ – choices (if applicable) and a
complete data set of a DIRP run (max. 1,000 analysis steps).
•Some user settings remain after power off until the user changes them again.
•DIRP (a special SCAN – procedure) to detect resonances within the frequency range of the
device.
•The results of a DIRP – analysis are displayed as a graph on the touch screen display (up to
1,000 increments).
•‘WOBBLE’- mode. If enabled, the signal will swing around the target frequency in a band
selectable in 27 steps between ±10Hz and ±9,000Hz . This is a global feature.
•‘PULSE’- mode. 4 pulse rates are selectable. This is a global feature.
•The content of the operating memory can be transferred via the RS232 communication interface
to an F-SCAN or to an F-SCAN2SATELLITE.
•‘F-SCAN’ software is available as an option. It allows to remote control the F-SCAN2from a PC
or Notebook via the RS232 communication interface. A serial printer can be attached instead of
a PC. The content of the operating memory, the DIRP data set, the DIRP graph, or the content
of ‘SETUP window 1’, can be printed to keep as a record.

Memory capabilities built into the F-SCAN2
The library functions containing the CLARK table of frequencies of pathogens and the
RIFE table of sequences of frequencies - addressing disease symptoms – are fixed in
permanent memory and cannot be altered by the user.
User controlled settings of the TIMERs, the upper (“F MAX”) and lower (“F MIN”)
frequency limit’s and of the “Delta F” remain - even when the unit is turned OFF - until the
user changes them to other values.
The operating memory, which is used by all functions, remains active as long as the
device is powered up. This is called a volatile, or non-permanent, memory. It’s content is
lost when the power is switched OFF.
It’s content can be erased too from the SETUP window 1 with “STORE” followed by ‘E’.
The operating memory is organized as follows:
It has fifty positions labeled ‘01’ to ‘50’. Any value is entered into position ‘01’ unless the
icon “MEMO” is touched after the confirming ‘E’. The memory position counter changes to
‘02’ and is ready for the next entry.
It is important to observe the content of the operating memory if different functions are
performed in succession without separating them by ‘power OFF’. Values stored in the
operating memory with the INPUT OF A FREQUENCY, TRANSFER, RECALL or after
selecting a CLARK application, are automatically appended.
Playback from the operating memory always starts from memory position ‘01’.
Which function to use ? Let us assume that................
….a well founded diagnostic method names one or several pathogens as the cause for a
disease. A check of the attached list of pathogens identified by Dr. CLARK reveals that all
are covered in the list.
See chapter USE OF THE INTERNAL FREQUENCY TABLES to proceed.
….there is reason to believe that resonances not yet identified by other diagnostic
methods take part in causing disease symptoms. An attempt should be made to find them
with a DIRP analysis and to treat. See chapter DIRP to proceed.
….there are symptoms of a health disorder which can be precisely named. A check of the
attached list of RIFE disease symptoms reveals that the disorder is named.
See chapter USE OF THE INTERNAL FREQUENCY TABLES to proceed.
….the name of the health disorder is NOT in the attached list of RIFE disease
symptoms. Other sources however offer a SEQUENCE OF FREQUENCIES to treat the
disorder which shall be used.
See chapter INPUT AND USE OF FREQUENCIES to proceed.
….an attempt to do a DIRP analysis did not yield trustworthy results. It is conceivable that
a ‘wide band SWEEP’ prior to another DIRP may improve the situation.
See chapter WIDE BAND SWEEP to proceed.
….the ZAPPER function shall be used. See chapter ZAPPER to proceed.

General comments
The unit confirms activities acoustically. This fact will not be mentioned in the detailed
description of the functions. Sound and display light can be switched ON and OFF.
The power supply warms up slightly during operation.
Connect the gold plated handheld electrodes – or other application parts - with the BNC-
connectors of the application cable. Place the electrode on the red lead (anode) in the
user’s left hand and the one on the blue lead (cathode) in his right hand, or apply other
electrodes where you see fit (NEVER on an open wound!).
NOTE: The term SQUARE WAVE is used in this document instead of
RECTANGULAR WAVE which is more commonly used in Europe.
How to start the F-SCAN2
The unit is ready for use as soon as the power supply is connected to an outlet, the
plug attached to the socket POWER and the ON OFF switch on the rear panel set
to ON.
This ‘Start-up’ window is displayed
after power ON. It shows the unit’s
name, the company and country of
origin and the release level of the
internal software.

The TOUCH SCREEN, SETUP window 1
The touch screen display is used to enter settings and commands for all functions of the F-
SCAN2. Its sensitive surface reacts to a soft touch with the plastic pen delivered with the
device or to a touch with the tip of a finger. The latter is less accurate, can cause wrong
entries and may leave undesired fingerprints. The touch screen can be cleaned with a soft
cloth – perhaps moistened with a mild glass cleaner.
IMPORTANT: NEVER TOUCH THE SCREEN SURFACE WITH A POINTED
INSTRUMENT OF ANY MATERIAL.
NEVER USE A SOLVENT TO CLEAN THE DISPLAY.

ADJUSTMENT OF AMPLITUDE
Low frequencies with high amplitudes can cause discomfort, skin irritations or even burns,
especially if inadequate electrodes or worn self adhesive pads are used.
F-SCAN2can generate square wave signals with amplitudes of up to 27Vpp with the
potentiometer fully open.
WE STRONGLY RECOMMEND THAT THE AMPLITUDE BE SET CAREFULLY PRIOR
TO A THERAPY WITH LOW FREQUENCIES.
This can be done as follows:
Turn the knob of the potentiometer counter clockwise to ‘0’.
Attach an application cable to the ‘OUTPUT” connector and to the electrodes to be used.
Connect the power supply to an outlet, attach the plug to the socket POWER and set the
switch in the back panel to ON.
The ‘Start-up’ window is displayed. Touch the tab THERA.
REMOVE THE ELECTRODES UNTIL READY FOR TREATMENT. MAKE SURE NOT TO
CHANGE THE SETTING OF THE POTENTIOMETER FOR THIS USER.
Touch “1 2 3“ to display the numerical block.
Input 100(Hz) and confirm with ‘E’.
Select the square wave signal.
HAND THE ELECTRODES TO THE USER.
TURN THE DIAL OF THE POTENTIOMETER SLOWLY
CLOCKWISE (UP) UNTIL THE USER REPORTS
‘FEELING THE CURRENT FLOW’ - OR ‘A SLIGHT
VIBRATION IN HIS HANDS’ - WHICH HE CAN EASILY
TOLERATE.

It is possible to check the input of the frequencies
with the icon’s “PREV” and “NEXT”.
If you want to sweep in the range between value 2
and 3 (in our example 2000 to 5000) go to memory
position ‘02’ and touch the line “Sweep To Next”. The
device calculates the steps for the sweep and
performs it for the time assigned to memory position
‘02’.
If you want to sweep longer than the time assigned
to an individual frequency:
Touch the tab SETUP.
Touch the icon “TIMER”.
Touch ‘50’ to switch the “50 TIMER”-function ON.
Touch the icon “PREV” until the memory position
counter shows ‘02’.
Enter the new time and confirm with ‘E’.
Touch the tab THERA.
Touch the icon “GO” to play back the content of all
memory positions with a frequency value greater
than 0.
