DYNATRON® 25 SERIES™ | OPERATOR’S MANUAL II
IMPORTANT: Before treating a patient with any Dynatron® 25 Series™ Device, see the “Contraindications, Warnings,
and Precautions” in this manual. Read the operating instructions for each modality carefully.
COMPLIANCE: e contents of this “Instructions For Use” manual are exactly the same in both the printed and electronic
forms.
INDICATIONS FOR USE
ELECTROTHERAPY: Electrical muscle stimulation therapy (Russian, Biphasic, High Volt) for:
1. relaxation of muscle spasm;
2. prevention or retardation of disuse atrophy;
3. increasing local blood circulation;
4. muscle re-education;
5. immediate post-surgical stimulation of calf muscles to prevent venous thrombosis
6. maintaining or increasing range of motion.
Transcutaneous electrical nerve stimulation and Interferential Current erapy (Interferential, Premodulated, and High
Volt) for: Symptomatic relief of chronic intractable and/or management of post-traumatic or post-surgical pain.
ULTRASOUND THERAPY: Ultrasound therapy is intended to generate deep heat within body tissues for the
treatment of selected medical conditions such as relief of pain, muscle spasms, and joint contractures, but not for
the treatment of malignancies.
CAUTION
Federal law restricts these devices for sale by or on the order of a physician, chiropractor, physical therapist, or
dentist licensed by the law of the state in which said person practices to use or order the use of the devices.
Risk of burns and re - Do not use near conductive materials such as metal bed parts, inner spring mattresses
and the like.
DANGER - Explosion Hazard: Do not use in the presence of ammable anesthetics.

Introduction
to the Dynatron®25 Series™
e powerful and versitle 25 Series oers 3 and 5 channel devices. All channels allow fully-independent treatment setups
oering Interferential, Premodulated, High Volt, Biphasic, Russian, Microcurent, and xed frequency IFC/Premod. In
addition, the 925 and 825 include Dynatronics’ Ultrasound Comboplus feature with the power to deliver up to 5 channels
of Stim and Ultrasound - all at the same time. All of the Dynatron 25 Series models oer 1, 2, and 3 MHz frequencies for
the greatest exibility in depth of treatment. Choose 1 MHz for deep treatments, 2 MHz for moderate depth, or 3 MHz for
supercial depth.

e 25 Series devices include the standard advantages of Dynatronics engineering, such as customizable treatments, electrode
conductance meters, and the popular Target feature. In addition all units oer the option of battery operation, making the devices
truly portable. e manufacturer’s warranty for these devices is two years (see full warranty details at the back of this manual).
is manual provides operator information and instructions for the four 25 Serises models: the 525, 625, 825, and 925.
e section that discusses Ultrasound and Combo treatments applies only to the Dynatron 825 and 925 models. All other
sections of this manual apply to all Dynatron 25 Series devices.
Simplied Setup
e design of the 25 Series top panel means treatment setup has never been easier. A few simple key presses are all you need
to fully set up a treatment. e User Interface intuitively groups and displays all the options for a modality setup on the large
LCD screen to ensure that treatment parameters can easily be selected and adjusted.
Each modality oers default settings which are automatically preset when the modality is selected—saving time in the treatment
setup. You can change these defaults to match your own most common treatment setups reducing setup time to a matter of seconds.
Language Selection
e default language on the 25 Series Family of devices is English; however, both French and Spanish are also available. To
change the default language: 1) Begin at the START UP SCREEN. 2) Press the FUNCTION KEY. 3) Use the toggle key under
the LANGUAGE WINDOW to select the desired language. 4) Press STOP to return to the START UP SCREEN.
Operator’s Prole
All operators shall be properly trained and certied medical practitioners or those working under the direction of a licensed
medical practitioner, capable of reading and comprehending instructions for use as described in this manual. Operators will
have reasonable mobility and dexterity to attach electrodes, apply ultrasound or light therapy accessories and monitor patient
WARNING
Power-on the device before attaching electrodes to the patient.

Installation and Features
Unpacking
When you receive the unit, immediately unpack it and all accessories and check for possible damage, obvious or concealed.
In case of damage, immediately notify the freight carrier and take any steps necessary to le a claim for the damage sustained.
Do not destroy or discard the shipping carton. e carton should be reused if the device must be shipped for any reason
including calibration. e carton is specially designed to protect the unit from shipping damage. Improper packaging of the
unit during transport can result in damage and invalidate the warranty.
Complete the warranty registration form located at the back of this manual and return it to Dynatronics within 30 days
of purchase. is is essential to insure you are not billed for services that are covered by the warranty policy. Warranty
registration should include serial numbers for both the device and soundheads.
Connect the AC power cord, which is provided as a hospital grade, UL listed plug, to a properly grounded 110/120V 60 Hz
AC outlet (the device will automatically switch to 220/240V 50 Hz when connected to a power source with that voltage).
e power cord must also be rmly plugged into the device itself. When the cord is properly connected, it cannot be easily
pulled out. Do not place the cord or the device in a place where the cord could be tripped over or accidentally pulled out of
its socket during a treatment.
Read the operating instructions in this manual before proceeding with a treatment.
