ULTRASOUND INSTRUCTIONS
Ultrasound
Instructions
Ultrasound therapy channels soundwaves through muscle, nerve, bone, and connective tissue to aid in reducing pain, muscle
spasms, and joint contractures.
e physiological eect of Ultrasound therapy depends upon the frequency of the Ultrasound signal. e lower frequency
(1 MHz) penetrates deeper than a higher frequency (such as 2 MHz or 3 MHz), thus the practitioner can decide which
frequency to use according to the condition and depth to be treated.
A section in this manual entitled “Ultrasound Usage Cautions” provides some general guidelines for Ultrasound treatment
and selection of the appropriate soundhead to help ensure safe and eective treatments are delivered to your patients. Further
information about Ultrasound application may be obtained from published medical literature.
WARNING
• ALWAYS keep the applicator soundhead in constant motion.
• ALWAYS keep the soundhead properly coupled to the patient’s skin or submerged underwater when intensity
is turned ON.
• Use ample conductive gel to ensure good coupling throughout the treatment. If needed, apply additional gel
during the treatment.
• See the section of this manual entitled “Contraindications, Warnings, and Precautions” for Ultrasound treatments.
• Be alert for any sign of periosteal (bone) pain.
• Be sure to read all instructions for operation before treating a patient.
• Use of controls or adjustments or performance of procedures other than those specied herein may result in
hazardous exposure to ultrasonic energy.
DYNATRON® 125 | OPERATOR’S MANUAL REV. 3 | 8/29/2017 10
ULTRASOUND INSTRUCTIONS
Make sure a soundhead is rmly plugged into the device before turning the device ON. When changing to a dierent size
soundhead, turn the machine o rst, remove the soundhead, plug in the desired soundhead, then turn the machine on
again. Please acquaint yourself with the following terms and device features prior to delivering an Ultrasound treatment.
Soundhead Warming
Soundhead Warming is an optional feature used to maintain a comfortable soundhead temperature for the patient. When
Soundhead Warming is ON, the soundhead should remain in its holder as a small amount of Ultrasound output is emitted
from the soundhead (0.1 W/cm2). e soundhead warming mode is automatically stopped during a treatment, and resumes
automatically as needed aer a treatment has ended. Although the Soundhead Warming feature defaults to OFF, it can be
turned ON at any time by going to the Setting Screen and pressing the WARMING key.
CAUTION
• Do not drop the soundhead on hard surfaces.
• Do not cool the soundhead with ice water or ice packs.
• Do not allow the soundhead to overheat repeatedly.
• Do not hold the soundhead in the air while a treatment is running.
All of these conditions are likely to damage the soundhead crystal and/or to stress electronic components in the
device. Damage caused by these conditions is not covered by warranty.
Coupling
e term “coupling” refers to the ability to deliver ultrasonic waves from the soundhead to the skin surface with as little
impedance or dissipation of power as possible. Coupling (contact between the soundhead and the treatment site) may be
provided by a coupling agent such as a gel or lotion. Any material used as a coupling agent must be highly conductive of
ultrasonic waves. Air is a very poor conductor of ultrasonic waves. Holding the soundhead in the air while a treatment is
running may also damage the soundhead crystal and/or stress electronic components in the device.
If any part of the soundhead is exposed to air during the treatment, coupling is decreased. e air bubbles in a whirlpool, for
example, can decrease the eective Ultrasound therapy to the patient. Avoid allowing any air between the soundhead and
the treatment area. Water is an excellent conductor of ultrasonic waves; therefore, underwater treatments provide excellent
coupling.
During any Ultrasound treatment the soundhead should be moved continuously, covering an area approximately 2-4 times
larger than the size of the soundhead. e full surface of the soundhead should maintain contact with the patient’s skin
(except with underwater treatments).
DYNATRON® 125 | OPERATOR’S MANUAL REV. 3 | 8/29/2017 11
ULTRASOUND INSTRUCTIONS
Head Temperature - Over Heating
If coupling (the eective degree to which the Ultrasound energy is delivered from the soundhead to the patient’s body) is not
adequate during treatment, the temperature of the soundhead rises and the patient does not receive the full intended dosage.
If the SOUNDHEAD reaches approximately 108 degrees, ULTRASOUND will be disabled and the Operations Screen will
read: “SOUNDHEAD IS TOO HOT! OUTPUT HAS BEEN DISABLED TO ALLOW COOLING.”
e soundhead must be cooled before the treatment can resume. When the soundhead cools suciently, press START
to resume the treatment. e output power resumes, the display returns to its normal state, and the timer resumes. e
soundhead should cool quickly if placed in the soundhead holder or if held exposed to the air. Larger soundheads take longer
to cool than smaller heads. If the soundhead is not cooling as quickly as needed to resume the treatment, it can be placed in
room temperature water to quicken the cooling process. Sometimes just applying more conductive gel will adequately cool
the head.
NEVER USE ICE OR ICE PACKS TO COOL THE SOUNDHEADS as this is likely to cause thermal shock to the electronic
components of the soundhead and may necessitate a costly repair. Heads damaged by thermal shock are not covered by the
warranty.
To prevent overheating of the soundhead, maintain good coupling throughout the treatment by applying ample conductive
gel or lotion. Reducing the power when treating an area where it is dicult to obtain good coupling will also keep the
soundhead from overheating.

ULTRASOUND MODALITY INFORMATION
Ultrasound
Modality Information
Ultrasound, by its very nature, has the ability to irritate the patient’s skin. While the benets of Ultrasound far outweigh any
disadvantages, certain precautions should be observed to assure maximum safety and comfort for your patients.
A patient’s tendency to have adverse reactions to Ultrasound is dependent upon several factors. Some of these factors are
discussed below.
Selecting the Appropriate Soundhead
Head and Crystal Size Comparison
DYNATRON® 125 | OPERATOR’S MANUAL REV. 3 | 8/29/2017 16
ULTRASOUND MODALITY INFORMATION
e selection of the appropriate soundhead is key to the success of the treatment and is based on the size of the area to be
treated. Ultrasound treatments should be kept specic to the tissue involved in pathology. A good guideline is 2 to 4 times
the size of the soundhead. For example:
• A 2 cm2 soundhead can deliver up to 4 Watts and is appropriate for small areas (i.e. hands, ngers, feet).
• A 5 cm2 soundhead can deliver up to 10 Watts and is appropriate for medium sized areas (i.e. extremities such as
arms, legs, and cervical areas).
• A 10 cm2 soundhead can deliver up to 10 Watts and is appropriate for large areas, i.e. torso and back).
Ultrasound is a directed beam of energy. erefore, not only will the average spatial intensity be a factor in the dosage the
patient receives, but the time delivered and area covered will matter as well. For example, an area of 50 cm2 is treated for 5
minutes. en an area of 200 cm2 is treated for 5 minutes. Both receive the same intensity. e 200 cm2 area however does
not receive the same dosage (only ¼ ) because as the soundhead is moved around the area it has to cover represents 4 times
as much tissue.
e Soundhead area measurement is the ERA (eective radiating area). Each soundhead has an eective radiating area. It is
not necessarily the outside diameter of the soundhead, but the area of the crystal inside, therefore special care should be
taken in selecting the correct size soundhead for the area to be treated according to the diameter of the crystal.
NOTE: If a patient experiences pain during a treatment, the size of the soundhead maybe inappropriate for the area
being treated, the intensity maybe too high, the treatment time maybe too long, or coupling maybe poor.
Penetration of Ultrasound Waves
e correct frequency should be selected for the depth of penetration desired. e amount of penetration needed is
determined by the density of tissue and the depth of the site to be treated. Care should be taken to select a penetration level
that does not cause periosteal (bone) pain.
e frequency determines the depth of penetration of
the Ultrasonic wave.
• Select 1 MHz for deep lesions; provides a
Half-Value Distance (HVD) of about 5cm.
• Select 2 MHz for moderate depth lesions; about
2.6cm HVD.
• Select 3 MHz for supercial lesions; about
1.5cm HVD.
HVD is the approximate point at which the Ultrasound
energy is reduced to half in the average human tissue.

Multi-Frequency Ultrasound
ULTRASOUND MODALITY INFORMATION
Types of Delivery
Ultrasound can be delivered in four dierent ways. You will likely only see two of the four methods in clinical practice.
1. Direct Contact Movable. Here the soundhead is placed in direct contact with the patient. A coupling agent is used
between soundhead and the patient’s skin. e soundhead is moved slowly, but continuously. is is the method of
choice.
e rate of speed at which the applicator moves across the skin is very important in determining how much Ultrasonic
output is delivered. If the rate is too slow, the patient may feel periosteal pain (bone ache/pain). If the rate is too fast,
or if the applicator head becomes uncoupled with the skin, the amount of treatment is reduced. Uncoupling can also
cause the soundhead to overheat.
2. Immersion Method. Here the area to be treated is placed underwater. e soundhead is rated IPX7, so it can be
immersed with the area to be treated. e water becomes the coupling agent. e head is always moving around the
surface area, but not in contact (1/2 to 1 inch away).
3. Hydrogel Disk. For treating crater wounds, cover the wound with a hydrogel disk and apply the soundhead to the
disk. is allows direct wound sonation without bringing the soundhead in direct contact with the wound.
4. Stationary Soundhead. is method is dangerous. Hot spots can develop. Do not use.

Treatment Intensity
Several factors come into play as one decides the level of intensity for the treatment.
1. Supercial lesions require less intensity.
2. Less intensity should be used if bone is supercial to the treatment eld.
3. Less intensity should be used when the stage of the injury makes heating questionable.
DYNATRON® 125 | OPERATOR’S MANUAL REV. 3 | 8/29/2017 18
ULTRASOUND MODALITY INFORMATION
4. Use a little lower intensity for the rst treatment to gauge response.
5. Patient feedback is key. A treatment should feel warm, but the patient should never feel heat, pain, stabbing, pricking
or dull ache.
Acute Conditions: ........................................ 0.1 – 0.5 W/cm2 (no appreciable thermal eect).
Sub-Acute Conditions: ........................... 0.5 – 1.0 W/cm2 (Mild to Moderate thermal eect).
Chronic Conditions: ............................1.0 – 2.0 W/cm2 (Moderate to Strong thermal eect).
NOTE: It is very common that intensity is always 1.5 W/cm2. is is incorrect in many cases. A more specic
intensity should be used based on patient response and stage of injury.
Frequency of Treatment
Treatment can be given daily. It is not uncommon to give Ultrasound twice daily, but this may be excessive. Some guidelines
may be helpful.
1. Daily may be the best maximum frequency.
2. Ultrasound can be eectively given every other day.
3. Ultrasound should give some positive benets by the 3rd or 4th application. If not, discontinue the treatment and
consider other options.
4. A maximum of 12 to 15 Ultrasound treatments should be given. If the result desired has not been reached by this
point, Ultrasound may not be the proper choice. EXCEPTION: Some Chronic conditions which cause adhesions.
Usage Cautions – Combination Treatments
When using a Stim device in conjunction with a Dynatron 125 device to output Stim through the soundhead, observe
all contraindication, warnings, precautions, and usage cautions provided by the manufacturer for all modalities involved.
Dynatronics’ stim devices ae recommended. Any other stim device used must not exceed the voltage levels of a Dynatronics’
stim device to ensure safety for the patient.
Poential for Burns or Periosteal Pain
Some patients’ skin is more sensitive to Ultrasound output. is can cause a reaction similar to a heat rash. It is also possible
for a patient to suer a burn from Ultrasound therapy if the therapy is not administered properly. is can occur for the
following reasons:
DYNATRON® 125 | OPERATOR’S MANUAL REV. 3 | 8/29/2017 19
ULTRASOUND MODALITY INFORMATION
• Intensity (power) too high
• Frequency too low
• Holding the soundhead in one place on the patient’s skin
• Moving the soundhead too slowly
• Treating an area where sensory nerve damage is present with a loss of normal skin sensation
• Time (Caution: Don’t treat too long).
Bony prominences are especially susceptible as they reect sound waves and increase intensity to the periosteum, resulting
in a burning sensation. Desensitized areas can be overheated or burned without the patient realizing it, so extreme care must
be taken with these patients (e.g. diabetes, neural damage, etc.)
Burns can be avoided as long as the treatment causes no pain, tingling, excess heat, or aching (for patients with normal skin
sensation). Use sucient coupling agent and make sure there are no bubbles in the gel. When treating in water, clear the
bubbles o the soundhead and the patient’s skin.
An un-calibrated soundhead can also cause tingling, excess heat, aching, or a burning sensation.

ULTRASOUND PROBLEM SOLVING
Ultrasound
Problem Solving
Whirlpool Treatments
If you are treating in a whirlpool, you may nd that the temperature in the whirlpool approaching 103˚F, causing the
overheated soundhead caution to appear on the Operations Screen. is is a cautionary warning only to let you know that
you are approaching the temperature limit. You may, however, continue with the treatment at this level. If your whirlpool
temperature is hot enough to cause the treatment to stop, you will need to adjust the temperature of the whirlpool.
Soundhead Temperature Too Cold
If the soundhead has been sitting in a very cold room or vehicle, it could be too cold to operate when plugged into the console.
e keypad may not respond to key presses and the device will not function until the soundhead is suciently warmed. You
must raise the temperature of the soundhead to about 60 degrees F in order for the machine to recognize that the soundhead
is present and to proceed with setting up a treatment. You can accomplish this with any of the following methods:
1. Press the at face of the soundhead against the palm of your hand for 30 to 60 seconds to warm it slightly. is
usually provides adequate warmth to the crystal to raise the temperature to the minimum acceptable level. Once the
crystal reaches this level, you can proceed with treatment.
2. You can also place the soundhead in room temperature water to warm the crystal. However, do not place the
soundhead in very hot water when the crystal is this cold as it could damage the crystal.
No Soundhead
If the device cannot detect a soundhead during setup or during an ultrasound treatment, the error message “SOUNDHEAD
DISCONNECTED! CORRECT PROBLEM WITH SOUNDHEAD TO RESUME!” will appear on the Operations Screen.
DYNATRON® 125 | OPERATOR’S MANUAL REV. 3 | 8/29/2017 21
ULTRASOUND PROBLEM SOLVING
If this error occurs, check to be sure the soundhead is rmly plugged into its connector. If you are unable to clear the message
by reconnecting the soundhead, contact Dynatronics’ Customer Service Department at 1-800-874-6251 for assistance.
Miscellaneous
Certain conditions can cause an error in operation. When this occurs, the machine will not allow a treatment to be set up or
delivered and will display an error message. Some errors are easily resolved by the following methods.
• Press STOP to stop the treatment, and turn the machine OFF then ON again. Always wait 5-10 seconds before
restarting the device.
• Check to be sure the soundhead has not become disconnected from the machine. e soundhead should be rmly
plugged into its port. Only Dynatronics soundheads may be used with this device. If the soundhead has been
dropped, it may be damaged. If the device operates normally with one soundhead, but not with another, the problem
may be a damaged soundhead and you must contact Dynatronics Customer Service.
• Make sure the soundhead is not too hot. In this case a Soundhead error will appear in the Operations Screen.
• Check to see if conditions may have caused extreme moisture/condensation in the device. is could occur when
the machine has become very cold and is brought indoors to a warm, humid environment. Condensation is a not
a serious condition. Allow the machine to sit in a dry environment until the condensation dries. e machine will
operate normally once the condensation is gone.
• Should the touch screen become unresponsive but the treatment timer continues to count down, you may continue
delivering the treatment until it ends. If the touch screen remains unresponsive, cycle the power o/on the device.
When the condition persists, contact the Customer Service Department.
If you have tried all of these suggestions, the device may require service by the manufacturer. In this case, make a note of the
error message and the sequence of events that caused the error, and contact Dynatronics Customer Service at 1-800-874-6251
for further assistance. Do not send the device to Dynatronics without rst contacting the Customer Service Department.
Replacing the Soundhead
e Ultrasound probe is a “smart” probe. e treatment head contains a microcontroller to store calibration data and
communicate that data to the console when the probe is plugged into the device. is feature allows the user to change
soundheads on the console without entering the calibration data associated with each soundhead.
In addition, the Dynatron 125 provides a “Head Calibration” key that gives the user the capability to enter parameters
manually in the event that parameters are lost or the user wishes to enter the parameters manually. is key, located on the
Settings Screen, is also used to access user calibration mode for soundheads. Soundheads should still be calibrated on an
annual basis.

COMBINATION THERAPY - USING THE COMBO JACK
Combination Therapy -
Using the Combo Jack
e Combo Jack provides the ability to combine electrical stimulation from an existing electrotherapy device with the
Dynatron 125 Ultrasound. e existing stimulator device must comply with IEC 601-1 and IEC 601-2-10 (general and
particular standards) requirements. e banana jack accommodates a Combination Lead Wire or requires the use of a
pin-to-banana adapter in order to provide Stim output through the Ultrasound head. e choice of electrotherapy modalities
that can be combined with an Ultrasound treatment depends on the stimulation device being used. Refer to the stimulation
device’s instruction manual for instructions regarding delivering electrotherapy. Dynatronics’ stim devices ae recommended.
Any other stim device used must not exceed the voltage levels of a Dynatronics’ stim device to ensure safety for the patient.
WARNING
• DO NOT use combination therapy for underwater treatment. Placing active electrodes underwater poses a
serious hazard to the patient!
• Use VERY LOW STIM INTENSITY for COMBO treatments.
• Remember to observe all contraindications, warnings, precautions, and usage cautions for BOTH Ultrasound
and Electrical Stimulation therapy when performing combination therapy.
• Since electrical current travels between the electrode and the soundhead during a COMBO treatment, the
electrode should be placed in proximity with the treatment area. Do not place the electrode and soundhead in
positions that will cause current to pass through contraindicated areas.
• Avoid removing the soundhead from the skin surface during “Stim rough Soundhead” treatments as
this may cause a momentary interruption of Stim current which may be uncomfortable to the patient. e
soundhead should remain in full contact of the skin until current output is stopped.
• Be alert for any sign of periosteal (bone) pain.
DYNATRON® 125 | OPERATOR’S MANUAL REV. 3 | 8/29/2017 25
COMBINATION THERAPY - USING THE COMBO JACK
Stim Through the Soundhead
With combination therapy, the soundhead is used in place of one electrode for a Stim treatment; and electrotherapy current
is delivered through the soundhead. is means that for a normal 2-electrode Stim treatment therapy, one electrode would
be placed on the patient with the soundhead acting as the second electrode site to complete the setup.
During the treatment, the stim current passes between the soundhead and the other electrode. At the same time ultrasonic
waves are introduced into patient tissue through the soundhead. Avoid touching the electrode with the soundhead during the
treatment. Keep the soundhead in contact with the patient’s skin at all times, and keep the intensity low for the Stim current.
WARNING
• When setting up a combination treatment, observe all Contraindications, Warnings, and Precautions for both
therapies to be used.
• Use VERY LOW STIM INTENSITY for COMBO treatments.
• Carefully comply with all instructions for the use of the existing electrotherapy device when it is used in
combination with the Dynatron 125.

Electromagnetic Environment Guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the Dynatron 125
(and accessories), including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter.
Recommended separation distance
d = 1.17 x P 80 MHz to 800 MHz
d = 1.17 x P 800 MHz to 2.5 GHz
where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in
meters (m).
Field strengths from xed RF transmitters, as determined
by an electromagnetic site survey, should be less than
the compliance level in each frequency range
Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply to all situations. Electromagnetic propagation is affected by
absorption and reection from structures, objects and people.
a. Field strengths from xed transmitters, such as base stations for radio (cellular/cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be pre-
dicted theoretically with accuracy. To assess the electromagnetic environment due to xed RF transmitters, an electromagnetic site survey should be considered. If the measured eld strength in the location
in which the Dynatron 125 (and accessories) is used exceeds the applicable
RF compliance level above, the Dynatron 125 (and accessories) should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Dynatron 125 (and accessories).
b. Over the frequency range 150 KHz to 80 MHz, eld strengths should be less than 3 V/m.
