Introduction

Introduction to the Dynatron 150plus

Your new Dynatron 150plus gives you a wide range of treatment capabilities, yet it is

compact, convenient and simple to use with its user-friendly touch panel for easy

treatment setup. Here are some highlights of your Dynatron 150plus:

• Patented Multi-Frequency Ultrasound. With the Dynatron 150plus you can

select three different frequencies without changing the soundhead. The

2 cm2, 5 cm2, and 10 cm2soundheads each operate at 1, 2, and 3 MHz.

• Customizable Duty Cycle. Select from 10, 20, 50 percent, and Continuous

duty cycle options.

• Head Warming. When the device is ON but idle, the soundhead is warmed

automatically. Head warming may be turned OFF, if it is not desired.

• Coupling Sensing. If coupling becomes inadequate during a treatment, the

displays flash and an audible beep is sounded to notify the user that coupling

should be corrected. If your device is version 1.04 or above, a bar graph will

appear.

• Modify Treatments In Progress. You can modify treatment time, power,

frequency, or duty cycle while a treatment is in progress. It is not necessary

to stop the treatment.

• Portable. The Dynatron 150plus is small and light-weight making it readily

portable. An optional carry case is available from your Dynatronics dealer.

• Optional Battery Operation. The device may be operated with power

supplied by an optional battery, offering greater flexibility in treatment sites.

• Two-Year Warranty on the device and soundheads.

This manual provides instructions for Ultrasound setup and treatment with the

Dynatron 150plus. Please read this manual, particularly the section on

contraindications, warnings, and precautions, before treating a patient with this

device.

About Ultrasound

Ultrasound therapy is supported by a wealth of scientific literature. Channeling

sound waves through muscle, nerve, bone, and connective tissue has been

documented to aid in reducing pain, muscle spasms, and joint contractures. The

Dynatron®150plus

“Ultrasound Usage “Cautions” in this manual provide some general guidelines for

Ultrasound treatment to help ensure you deliver safe and effective treatments to your

patients. Further information about Ultrasound may be obtained from published

medical literature.

Before using your Dynatron 150plus, be sure to read the operating instructions,

contraindications, warnings, and precautions contained in this manual.

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

carrier and take any steps necessary to file a claim for the damage sustained. Do not

destroy or discard the shipping carton. The carton should be reused if the device must

be shipped for any reason. The 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 found at the back of this manual and return it

to Dynatronics within 30 days of purchase. This is essential to insure you are not

billed for services that are covered by the warranty policy.

Connect the AC power cord, which is equipped with 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. 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 and the contraindications, warnings and precautions in

this manual before proceeding with a treatment.
