WARNINGS & PRECAUTIONS
CAUTION: Federal law restricts this device for sale or use by, or on the order of, a Practitioner
licensed by the laws of the state in which he/she practices to use or order the use of the device.
Please note that Accelerated Care Plus cannot provide medical advice. If you have specific

Warnings
•Do not operate this device until the User Manual, including all Indications for Use, Contraindications, Warnings
and Precautions, have been carefully read and understood.
•Operation of this device or placement of lead wires, probes, pads and electrodes in close proximity (less than 5
feet) to an operating shortwave or microwave diathermy unit may produce instability in the device output or
burns at the treatment site. Lead wires and device can pick up the magnetic field output of the diathermy and
through induction convert it into an electrical field, transmit the energy into the patient increasing the current
density at the electrodes of applicators. Since the patient may not feel the 27 MHz frequency, they lack the
protective sensation and tissue burns could result. Short-wave field could potentially damage or reset medical
devices in close proximity to the drum applicator.
•Treatment should not be applied over the carotid sinus nerves, (located in the anterior neck triangle), including,
stellete ganglion, vagus nerve, or laryngeal or pharyngeal muscle. Particular care should be taken for patients
with a known sensitivity to the carotid sinus reflex, as carotid sinus stimulation may alter blood pressure and
cardiac contractility.
•Do not apply treatment over testes, heart or eyes. Thermal effects or electrical stimulation may affect organ
function.
•Do not apply over or in close proximity to active cancer (except in terminal / palliative / hospice care), as
therapy may increase blood flow to the tumor.
•Treatment should not be applied when high fever is present, over swollen, severe infection, (osteomyelitis,
sepsis, tuberculosis, etc.), or inflamed areas or skin eruptions, (e.g., phlebitis, thrombophlebitis, varicose veins,
etc.).
•Do not apply over the lumbar or abdominal region, or over the uterus during pregnancy (to prevent uterine
contraction), or during menstruation as therapy may temporarily increase menstrual flow.
•The long-term effects of chronic electrical stimulation are unknown. To date, the only negative effects reported
are based on skin and tissue irritation under the electrode sites associated with chronic estim use.
•Stimulation should not be applied transthoracically in the vicinity of the heart, as introduction of electrical
current into the heart may cause cardiac arrhythmias.
•Treatment should not be applied transcranially.
•Stimulation should not be applied to patients connected to patient monitoring equipment, as the stimulation may
have an affect on the proper operation of the monitoring equipment.
•Stimulation should not be applied directly over external or implanted stimulator systems, such as shunts,
infusion pumps, stomach, bladder, brain, spinal cord, bone growth, or other implanted stimulators.
•Neuromuscular electrical stimulation (NMES) should not be applied directly over or in close proximity to Deep
Vein Thrombosis (DVT), as it activates the muscle and causes muscle contractions. This should be avoided in
tissue following an acute DVT when the thrombosis is not completely resolved. Therapists should follow the
guidelines provided by the referring physician on recommended activity level and modality use. If the patient is
not permitted exercise, NMES therapy should be avoided. Generally, NMES over a DVT of six weeks or less
should be avoided altogether.

Precautions
•Application site and settings should be based on the guidance of the prescribing practitioner.
•All equipment and accessories should be kept out of the reach of children or unqualified persons.
•Do not connect this device to any wall outlet that has not been properly grounded, or to any electrically non-
isolated medical device.
•Use only ACP specified accessories and/or supplies with ACP devices. Do not use any power cords, or power
supplies, other than the ones provided or specified for this device. Use of any other power supply could
seriously damage the device and will void the warranty.
•When cleaning the device, never immerse them or wash them with water. See the Infection Control section in
this manual for cleaning instructions. Devices should not be submerged in water or other liquids.
•Failure to follow the manufacturer’s prescribed maintenance for this device may lead to device failure and
transient or unreliable performance. State and federal survey and JCAHO require all equipment to be
maintained and calibrated according to the manufacturer recommended schedules.
•A potential electric shock hazard exists once the device outer casing has been in part, or fully, removed. Only
qualified service personnel should perform Service and repairs. Warranty will be voided if the outer casing has
been removed or tampered with.
•Do not apply over areas of hemorrhage or active bleeding. Modalities should be applied following cessation of
hemorrhage or active bleeding as they may promote increased circulation and inhibit coagulation.
•Inspect and cleanse the skin prior to application. Following treatment check the skin for evidence of irritation
or burns, and if present, treat as appropriate. If the patient has, or complains of, skin irritation following
treatment, shorten the treatment time on the next treatment session, or use an alternative type of therapy or
electrode placement.
•Gradually increase the output intensity/power to required dose or patient tolerance while monitoring the device
display.
•Caution should be taken with patient exhibiting psychological or physical hypersensitivity to the therapeutic
treatment. Several attempts should be made to place them at ease so that their confidence and cooperation can
be gained during the treatment.
•The treatment area should be checked from time to time, and if there is evidence of, or if the patient complains
of, pain during treatment, adjust the output downward until it is tolerated by the patient. If the patient continues
to complain of pain, discontinue the treatment and shorten the treatment time on the next treatment session, or
use an alternative type of therapy or electrode placement.
•Do not apply treatment directly over/under hot or cold packs. Caution is recommended when treatment follows
the application of hot or cold therapy, which may alter the patient’s sensation. Application of thermal agents
over areas of impaired circulation should be performed with caution as the circulation may be insufficient to
heat or cool the tissue, altering the patient’s perception of warmth and pain, and burns or tissue necrosis may
result from subsequent treatment.
•Caution is recommended when treatment follows the application of medicated patches, salves, or creams which
may alter the patient’s sensation. If there is a medical necessity to perform such treatments, these patients
should be monitored diligently during application. The presence of electrical stimulation may be altered by the
presence of these materials on the patient’s skin.
•Caution should be used over areas of body where circulation is impaired, or which lack normal sensation.
Absent or diminished sensation should be avoided or, if unavoidable, treated with caution. Establishment of
acceptable intensity levels for desensitized areas may be related to the intensity levels tolerated on normal skin
in opposite or related body parts.
•Caution should be used in the presence of recent surgical procedures, fractures or healing bone and soft tissue
when muscle contraction may disrupt the healing process.
•Caution should be used for persons with suspected or diagnosed heart problems.

•Caution should be used for patients with suspected or diagnosed epilepsy.
•Electrodes should not be placed in direct contact or in close proximity (one inch or less) of each other during
treatment. Electrodes placed in contact or in close proximity can lead to high energy density and skin burns
under or between the electrodes.
•Care should be used when removing electrodes after treatment, in order to minimize the potential for skin
tearing. Skin should be inspected after removal of electrodes for any signs of tearing or irritation.
•Do not connect the stimulator to any electrical equipment for combination therapy except the Omnisound®
family of ultrasounds.
•ACP does not recommend the use of the Denervated Muscle or Low Intensity DC protocols, and does not
supply the DC or Microcurrent adapter required for use with these protocols. If this device is used with a DC or
Microcurrent adapter, follow the specific treatment guidelines, indications, contraindication, warning and
precautions specified in the DC or Microcurrent adapter manual. Do not use any protocols requiring the use of
the DC or Microcurrent adapter without first having plugged the adapter into the appropriate channel.

Introduction
The OMNISTIM®500 is designed to provide Interferential Current Therapy (IFC), Medium Frequency Alternating
Currents (MFAC), Low Voltage Pulsed Current (LVPC) and High Voltage Pulsed Current Therapy (HVPC). Its
two separate generators produce medium frequency (2000, 2500, 4000 or 5000 Hz) alternating current in continuous
or modulated modes. Two isolated output circuits with independent intensity controls are provided. The output of
each circuit is easily determined in milliamps through the display screen. The digital timer allows the operator to
select the length of the total treatment time and to monitor the time remaining in minutes.
The OMNISTIM®500 offers Frequency Difference (FD) and Full Field (FF) Interferential Current Therapy. An
interferential vector scanning mode can be turned off or on for stationary or continuous movement of the
interferential field.
The OMNISTIM®500 MFAC and LVPC modes with fully adjustable ON and OFF times and ON and OFF ramps
provides a wide variety of uses for muscle re-education and muscle spasm reduction protocols for innervated
muscle.
The OMNISTIM®500 provides High Voltage Pulsed Current (HVPC) on one channel. Continuous or surged
operation with fully adjustable ON and OFF times and ramps allow applications of HVPC therapy. Increasing
circulation, pain control and muscle re-ed can be set up in this mode.

Factory Settings
The OMNISTIM®500 comes with the following factory settings:
Button Speed, A & B Output 87
Button Speed, Beat, etc. 93
Button Delay, all 40
Audio ON
Screen Contrast 5
These are generally suitable for most clinicians. To adjust these default settings proceed as follows:
1. When the main screen comes up and states “SELECT MODALITY/PROGRAM” push the SELECT
PARAMETERS button repeatedly to display the factory settings. You will then be able to adjust the
selected factory settings by pressing the TIME/PARAMETER up/down button. The new settings will be
saved from use to use as long as you do not remove the batteries or allow a full discharge of the unit.
2. The screen contrast sets the appropriate viewing angle for easy screen legibility.
3. The button speed for output A & B sets the speed at which output will increase and decrease when you
push the buttons. This should generally be set at a slower speed (80 - 90) so as not to startle the patient.
4. The Button speed BEAT Etc. controls the scrolling speed of all of the remaining buttons on the system. A
speed of 90 to 95 is typical if you have good coordination and hand control.
5. The button delay represents the amount of time that you have to push and hold the buttons down before
they will begin to increment automatically at the button speed. The smaller the number the faster the
response time.
6. Audio on or off disables or enables the audio system that beeps at the end of the treatment and during the
NMES programs.
NOTE: The factory settings cannot be accessed during operation and are only available following the start
up screen. The settings will reset to their initial default parameters if the batteries are removed or the unit
is fully discharged. To restore the new settings follow the procedure in Appendix I.
