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

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.
