Introduction To The Dynatron 850Plus™ And 550Plus; New Features - Dynatronics Dynatron 850 Plus Service Manual

Dynatron 850plus™ and 550plus™
The Dynatron 850plus and Dynatron 550plus offer the practitioner a wide range of treatment
options in a single device. Both devices provide interferential and premodulated therapy,
high voltage pulsed stimulation, Russian and biphasic stimulation, and microcurrent. The
850plus also includes ultrasound and combination therapy.
The devices include the advantages of earlier Dynatronics models, such as customizable
treatments with convenient setup. In addition, these units are smaller and lighter in weight
than earlier models and now offer the option of battery operation, making the devices truly
portable. One additional channel is now dedicated to high volt therapy, allowing a greater
variety of simultaneous treatments. The manufacturer's warranty for these devices is now
two years (see full warranty details at the back of this manual).
This manual provides operator information and instructions for both of these models. The
sections that discuss ultrasound and combination treatments apply only to the Dynatron
850plus model. All other sections of this manual apply to both devices. Sections of this
manual that apply only to the Dynatron 850plus are clearly marked.

New Features

For models having software greater than Rev. 1.01 or later, the following new features have
been added (effective January 1998).
• Conductance Bar Graph. A graphical representation of conductivity during and
interferential, premodulated, or microcurrent treatment.
• Ultrasound Coupling Bar Graph. Shows soundhead coupling during an ultrasound
treatment.
• Soundhead Temperature Bar Graph. Indicates when soundhead temperature is too hot
during a treatment.
• "Lead" warning. A new warning displayed if the device detects an open circuit,
indicating no patient current is being delivered and the treatment setup must be inspected.
• New warnings notifying the user when the soundhead is too hot, or when the soundhead
is not detected by the device
These new features are described in greater detail in the treatment instructions later in this
manual. The determine the software revision level for the Dynatron device, power the device
