1.2 SAFETY PRECAUTIONS (continued)

• These devices are restricted to sale by, or on the order of, a physician or licensed practitioner. This device should be used only under the continued supervision of a physician or licensed practitioner. • For continued protection against fire hazard, replace fuses only with ones of the same type and rating. • Make certain the unit is electrically grounded by connecting only to a grounded electrical service receptacle conforming to the applicable national and local electrical codes. • Care must be taken when operating this equipment around other equipment. Potential electromagnetic or other interference could occur to this or to the other equipment. Try to minimize this interference by not using other equipment in conjunction with it. • The safety of TENS waveforms for use during pregnancy or birth has not been established. • TENS is not effective for pain of central origin. This includes headache. • TENS should be used only under the continued supervision of a physician or licensed practitioner. • TENS waveforms have no curative value. • TENS is a symptomatic treatment, and as such, suppresses the sensation of pain which would otherwise serve as a protective mechanism. • The user must keep the device out of the reach of children. • Electronic monitoring equipment (such as ECG monitors and ECG alarms) may not operate properly when TENS stimulation is in use. • Powered muscle stimulators should be used only with the leads and electrodes recommended for use by the manufacturer. • In the event that an Error message or Warning appears beginning with a 2 or 3, immediately stop all use of the system and contact the dealer or Chattanooga Group for service. Errors and Warnings in these categories indicate an internal problem with the system that must be tested by Chattanooga Group or a Field Service Technician certified by Chattanooga Group before any further operation or use of the system. Use of a system that indicates an Error or Warning in these categories may pose a risk of injury to the patient, user or cause extensive internal damage to the system. • Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous exposure to ultrasonic energy. • Before administering any treatment to a patient you should become acquainted with the operating procedures for each mode of treatment available, as well as the indications, contraindications, warnings, and precautions. Consult other resources for additional information regarding the application of Electrotherapy and Ultrasound. • To prevent electrical shock, disconnect the unit from the power source before attempting any maintenance procedures. • Keep electrodes separated during treatment. Electrodes in contact with each other could result in improper stimulation or skin burns. • Long term effects of chronic electrical stimulation are unknown. • Stimulation should not be applied over the anterior neck or mouth. Severe spasm of the laryngeal and pharyngeal muscles may occur and the contractions may be strong enough to close the airway or cause difficulty in breathing.

• Stimulation should not be applied transthoracically in that • • •

the introduction of electrical current into the heart may cause cardiac arrhythmia. Stimulation should not be applied over swollen, infected, and inflamed areas or skin eruptions, (e.g., phlebitis, thrombophlebitis, varicose veins, etc.). Stimulation should not be applied over, or in proximity to, cancerous lesions. Output current density is related to electrode size. Improper application may result in patient injury. If any question arises as to the proper electrode size, consult a licensed practitioner prior to therapy. Unplug the unit from the power source before attempting removal or replacement procedures to prevent electrical shock. Use only Degassed Water in Power Meter for testing Ultrasound Applicators. Use of other types of water will cause false test results. Refer to page 21 for Degassed Water Recipes. Do not aerate water when filling Power Meter. Unit failing Dielectric Withstand Test or Leakage Test could indicate serious internal problems! Do not place unit back into service! Send unit to factory for repair! Do not attempt to repair.



1.2 SAFETY PRECAUTIONS (continued)

Stimulus delivered by the TENS waveforms of this device, in certain configurations, will deliver a charge of 25 microcoulombs (μC) or greater per pulse and may be sufficient to cause electrocution. Electrical current of this magnitude must not flow through the thorax because it may cause a cardiac arrhythmia. Patients with an implanted neurostimulation device must not be treated with or be in close proximity to any shortwave diathermy, microwave diathermy, therapeutic ultrasound diathermy, or laser diathermy anywhere on their body. Energy from diathermy (shortwave, microwave, ultrasound, and laser) can be transferred through the implanted neurostimulation system, can cause tissue damage, and can result in severe injury or death. Injury, damage, or death can occur during diathermy therapy even if the implanted neurostimulation system is turned “off.”

2 THEORY OF OPERATION


2.1 OVERVIEW

The Intelect Mobile 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, Stim Boards, Ultrasound Board (Combo only), Ultrasound Applicator (Combo only), and Power Supply Circuits. 2.2 POWER SUPPLY CIRCUIT

A universal 75 Watt input power supply provides each system with the required 24 volts DC. The supply is connected to the mains at all times when the Mains Power Cord is attached and plugged into an outlet supplying 100 - 240 VAC. The 24 V 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 Stim Boards, Ultrasound Board, User Interface, and Accessories. The Control Board communicates to the Stim Boards and Ultrasound Board through a proprietary 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 systems. Sound output is generated by the Control Board and routed to an internal speaker. 2.4 STIM BOARDS

The Stim Boards create all muscle stimulation output. Communication to the Stim Boards is via a proprietary bus. A Processor on each Stim Board acts on messages passed to it by the Control Board to set up waveforms and adjust output amplitude. Information can likewise be passed from each Stim Board back to the Control Board for monitoring current, etc. If a Stim Board does not respond as expected to a command from the Control Board, output is stopped and an Error Message is generated. 2.5 ULTRASOUND BOARD AND APPLICATOR COMBINATION SYSTEMS ONLY

The Ultrasound Board generates the 1 or 3.3 MHz output to drive the Sound Head of the Applicator. The Ultrasound Board is accessed through the proprietary bus 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 to the Control Board. By storing the calibration data in the Applicator, there is no calibration necessary for the Ultrasound Board and any calibrated Chattanooga Group Intelect Advanced or Intelect Mobile Ultrasound Applicator can be connected and operated to provide accurate coupling and output. 2.6 USER INTERFACE AND ACCESSORIES

The LCD display panel provides the operator visible feedback in the way of menu choices. Pressing the User Interface buttons makes selections from the menus. The Control Board interprets these user inputs and responds accordingly. Audible feedback is given for such events as key presses and end of treatment. 2.7 NIMH BATTERY

The NiMH Battery Module incorporates a Nickel Metal Hydride (NiMH) Battery Pack and a PC Board. The PC Board monitors the Battery Charge Level. The Battery Pack supplies the required 24 VDC to the system which is then distributed to the respective PCB’s through the Universal Power Supply. The Battery Pack is interfaced with the system via a Wire Harness that facilitates communication with the Control Board and delivery of power to an Electrotherapy or Combination Therapy System. When the Therapy System is connected to a Mains Power Supply via the Mains Power Cord, the NiMH Battery Pack will charge. Once the Battery Pack is fully charged, the software will stop the charging process, eliminating the possibility of overcharging. Battery power is used only when the Therapy System is not connected to a Mains Power Supply.

4.3 INTELECT ELECTROTHERAPY WAVEFORM SPECIFICATIONS

NOTE: All waveforms except High Voltage Pulsed Current (HVPC) of the Intelect Mobile Therapy System have been designed with a 200 mA current limit. VMS™, and all TENS waveform output intensities are measured, specified, and listed to peak, not peak to peak. All Waveforms are available on all channels.

The specifications found in this section provide the necessary waveform specifications to aid in troubleshooting. A waveform graphic from an oscilloscope is also provided for clarification. Refer to this section when performing troubleshooting, replacement, and repair of the Intelect Mobile Stim and Combo Systems.

A. IFC (Interferential) Traditional (4 Pole)- Figure 4.3

Interferential Current is a medium frequency waveform. Current is distributed from two channels (four electrodes). The currents cross in the body within the area being treated. The two currents interfere with each other at this crossing point, resulting in a modulation of the intensity (the current intensity increases and decreases at a regular frequency).

A. General

1. The following information is intended to aid in troubleshooting the major components of the Intelect Stim and Combo Therapy Systems to “Board Level” only. These tests are FACTORY standard testing procedures and methods used at the factory before shipment of any Intelect 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. 3. Once a particular PC Board has been determined as bad, refer to the appropriate Removal and Replacement Section of this Manual for proper replacement.

NOTE: Two liter soft drink 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. Do not use Tap Water or Distilled water in the Ultrasound Power Meter. Use only Degassed Water in order to obtain correct test results. The chart below illustrates the oxygen content of Degassed, Tap, and Distilled Water.
