2- THEORY of OPERATION
Intelect®/Genisys® Ultrasound Therapy Systems
2.1 Overview
The Intelect/Genisys Ultrasound Therapy Systems are comprised of several PC board assemblies housed within a
common enclosure. These assemblies each support a distinct function in the product. The basic elements are User
Interface, Control Board, Ultrasound Board, Ultrasound Applicator, and Power Supply Circuits.
2.2 Power Supply Circuits
A universal input power supply provides all parts of the system with 12 volts DC. The supply is connected to the mains
at all times when the cord is attached. The power switch on the top of the unit, switch the 12V output of the power
supply to the different components in the system by way of the Power Distribution Board. The 12V supply is regulated
locally at each PC board as required.
2.3 Control Board
The Control Board serves just as its name implies. It controls the operation of the ultrasound board, user interface and
optional accessories. The control board communicates to the ultrasound board through a proprietary 8-bit parallel bus.
The control board drives the display. The control board reads the menu buttons. The control board also reads the
amplitude and the contrast control on the system. Sound output is generated by the control board and routed to an
internal speaker.
2.4 Ultrasound Board and Applicator
The ultrasound board generates the 1 or 3.3 MHz output to drive the ultrasound Sound Head. The ultrasound
board is accessed much like an I/O port by the control board. It can provide current and voltage information
about the ultrasound output of the board. The calibration data for the Sound Head is passed through the
ultrasound board from the applicator up to the control board. By storing the calibration data in the applicator
there is no calibration necessary for the ultrasound board. Calibrated Chattanooga Group Ultrasound Applicators,
designed specifically for the Intelect/Genisys Ultrasound Therapy Systems, can be connected and operated to
provide accurate coupling and output.
2.5 User Interface and Accessories
The LCD display panel provides the operator visible feedback in the way of menu choices. Pressing the menu
buttons makes selections from the menus. The control board interprets these user inputs and responds
accordingly. Audible feedback is given as well for events such as keypresses and end of treatment.
The Optional Battery mounts in the system bottom and supplies 24 VDC to the power supply. The Power Supply
distributes the power required to the system as needed. The charging circuit for the battery is incorporated on the
Control PCB. An icon on the display reflects the available amount of charge in the battery. When the system is
connected to an approved power outlet and a battery is installed in the system, the system will charge the battery
to full capacity. The incorporated charger will not overcharge the battery.

5.2 Intelect/Genisys Ultrasound Diagnostics
A. General
1. The following information is intended to aid in
troubleshooting the major components of the
Ultrasound Therapy Systems to “Board Level”
only. These tests are OEM standard testing
procedures and methods used at the factory
before shipment of any Ultrasound Therapy
System.
2. Due to the complex nature of the
technology utilized by Chattanooga Group,
the recommended troubleshooting
techniques are to determine “Bad Board”
and board replacement only. No board
component level troubleshooting is
recommended nor will information or parts
be supplied by Chattanooga Group. Any
board component level troubleshooting
performed will be at sole risk and liability of
the Service Technician performing such
troubleshooting techniques.
B. Special Tools, Fixtures & Materials Required
1. Certain tests require the use of special Tools
and/or Fixtures. These will be listed at the
particular test where they are required. Testing
with any other special tool or fixture other than
those stated could give erroneous readings or
test results. Always perform the tests exactly as
stated to ensure accurate results.
2. Any special tools or fixtures required can be
obtained through Chattanooga Group, Service
Department.
3. Scope and other standard test equipment
settings will be listed for each test performed to
aid in performing the test to OEM standards and
ensure proper readings.
4. The troubleshooting and repair of the Ultrasound
Therapy Systems should be performed only by
authorized technicians trained and certified by
Chattanooga Group.
C. Equipment Required

products.
7. Degassed Water (< 5 ppm) for Ultrasound Power
Meter.
Recipe(s) for Degassed Water
1) Boil Distilled Water for 30 minutes. Place
water in a nonporous container and
immediately cover with cellophane. Allow to
cool to room temperature of approximately
21°C (70°F). May be refrigerated to aid
cooling time.
2) Bring Distilled Water to a boil. Place the
container under vacuum for 5 to 10 minutes.
8. Dissolved Oxygen Test Kit. Used to test oxygen
level of degassed water.
NOTE:
Two liter softdrink bottles are ideal storage and transport
containers for degassed water as they are designed to
keep oxygen out. Do not allow aeration of degassed water
during transport or filling of the power meter.
