Non-Ionizing Electromagnetic Radiation

Vectra Genisys® Therapy System

SAFETY PRECAUTIONS

3

Read, understand, and practice the precautionary and operating •
instructions. Know the limitations and hazards associated with
using any electrical stimulation or ultrasound device. Observe the
precautionary and operational decals placed on the unit.

DO NOT operate this unit in an environment where other devices

•

are being used that intentionally radiate electromagnetic energy in
an unshielded manner.

Ultrasound should be routinely checked before each use to

•

determine that all controls function normally, especially that
the intensity control does properly adjust the intensity of the
ultrasonic power output in a stable manner. Also, determine that
the treatment time control does actually terminate ultrasonic power
output when the timer reaches zero.

DO NOT use sharp objects such as a pencil point or ballpoint pen to

•

operate the buttons on the control panel.
This unit should be operated, transported and stored in

•

temperatures between 59° F and 104° F (15° C and 40° C), with
Relative Humidity ranging from 30%-60%.

Handle Ultrasound Applicator with care. Inappropriate handling of

•

the Ultrasound Applicator may adversely affect its characteristics.
Before each use, inspect Ultrasound Applicator for cracks, which

•

may allow the ingress of conductive fluid.

Inspect Applicator cables and associated connectors before •
each use.

The Vectra Genisys Therapy System is not designed to prevent the

•

ingress of water or liquids. Ingress of water or liquids could cause
malfunction of internal components of the system and therefore
create a risk of injury to the patient.

This equipment generates, uses and can radiate radio frequency

•

energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to other devices in
the vicinity. However, there is no guarantee that interference will
not occur in a particular installation. Harmful interference to other
devices can be determined by turning this equipment on and off.
Try to correct the interference using one or more of the following:
reorient or relocate the receiving device, increase the separation
between the equipment, connect the equipment to an outlet on a
different circuit from that to which the other device(s) are connected
and consult the factory field service technician for help.

Nylatex® Wraps contain dry natural rubber and may cause allergic

•

reactions in patients with allergies to latex.
Use of parts or materials other than Chattanooga's can degrade

•

minimum safety.

Vectra Genisys® Therapy System

SAFETY PRECAUTIONS

4

U.S.A. Federal Law restricts these devices to sale by, or on the order •
of, a physician or licensed practitioner. This device should be used
only under the continued supervision of a physician or licensed
practitioner.

Make certain the unit is electrically grounded by connecting only to a

•

grounded electrical service receptacle conforming to the applicable
national and local electrical codes.

Care must be taken when operating this equipment around other

•

equipment. Potential electromagnetic or other interference could
occur to this or to the other equipment. Try to minimize this
interference by not using other equipment in conjunction with it.

The safety of TENS waveforms for use during pregnancy or birth has

•

not been established.
TENS is not effective for pain of central origin. (This includes

•

headache.)
TENS should be used only under the continued supervision of a

•

physician or licensed practitioner.
TENS waveforms have no curative value.

•

TENS is a symptomatic treatment, and as such, suppresses the •
sensation of pain which would otherwise serve as a protective
mechanism.

The user must keep the device out of the reach of children.

•

Electronic monitoring equipment (such as ECG monitors and ECG •
alarms) may not operate properly when TENS stimulation is in use.

Powered muscle stimulators should be used only with the leads and •
electrodes recommended for use by the manufacturer.

In the event that an Error message or Warning appears beginning

•

with a 2 or 3, immediately stop all use of the system and contact the
dealer or DJO, LLC for service. Errors and Warnings in these categories
indicate an internal problem with the system that must be tested by
DJO, LLC or a Field Service Technician certified by DJO, LLC before any
further operation or use of the system. Use of a system that indicates
an Error or Warning in these categories may pose a risk of injury to
the patient, user or cause extensive internal damage to the system.

Use of controls or adjustments or performance of procedures other

•

than those specified herein may result in hazardous exposure to
ultrasonic energy.

Before administering any treatment to a patient you should become

•

acquainted with the operating procedures for each mode of
treatment available, as well as the indications, contraindications,
warnings and precautions. Consult other resources for additional
information regarding the application of Electrotherapy and
Ultrasound.

To prevent electrical shock, disconnect the unit from the power

•

source before attempting any maintenance procedures.

Stimulation should not be applied over the anterior neck or mouth. •
Severe spasm of the laryngeal and pharyngeal muscles may occur
and the contractions may be strong enough to close the airway or
cause difficulty in breathing.

Stimulation should not be applied transthoracically in that the

•

introduction of electrical current into the heart may cause cardiac
arrhythmia.

Stimulation should not be applied over swollen, infected, and

•

inflamed areas or skin eruptions, e.g., phlebitis, thrombophlebitis,
varicose veins, etc.

Stimulation should not be applied over, or in proximity to, cancerous

•

lesions.
Output current density is related to electrode size. Improper

•

application may result in patient injury. If any question arises as to
the proper electrode size, consult a licensed practitioner prior to
therapy session.

The Vectra Genisys Therapy System optional modules and associated

•

accessories are designed for use only with the Chattanooga Vectra
Genisys Electrotherapy and Combination Therapy Systems.

Remove the Ultrasound or Laser Applicator by pulling the cable

•

connector only. DO NOT remove by pulling the cable.

Stimulus delivered by the TENS waveforms of this •
device, in certain configurations, will deliver a charge of
25 microcoulombs (µC) or greater per pulse and may be
sufficient to cause electrocution. Electrical current of this
magnitude must not flow through the thorax because it
may cause a cardiac arrhythmia.

Patients with an implanted neurostimulation device

•

must not be treated with or be in close proximity to
any shortwave diathermy, microwave diathermy,
therapeutic ultrasound diathermy or laser diathermy
anywhere on their body. Energy from diathermy
(shortwave, microwave, ultrasound and laser) can be
transferred through the implanted neurostimulation
system, can cause tissue damage, and can result in
severe injury or death. Injury, damage or death can
occur during diathermy therapy even if the implanted
neurostimulation system is turned “off.”

Handle, clean and dispose of components and accessories

•

that have come in contact with bodily fluids according
to National, Local and Facility rules, regulations and
procedures.

NiMH Batteries contain Class E Corrosive materials. In the •
event of battery cell rupture or leakage, handle Battery
Module wearing neoprene or natural rubber gloves. Contents
of a ruptured or leaking battery can cause respiratory
irritation. Hypersensitivity to nickel can cause allergic
pulmonary asthma. Contents of cell coming in contact with
skin can cause skin irritation and/or chemical burns.

Never, under any circumstances, open the Battery Module •
housing or cells. Should an individual cell from a battery
become disassembled, spontaneous combustion of the
negative electrode is possible. There can be a delay between
exposure to air and spontaneous combustion.

Charge the Battery Module according to the instructions •
found in this manual. Never attempt to charge the Battery
Module on any other charging mechanism.

Use the Battery Module only with the Vectra Genisys Therapy •
Systems.

Do not reverse the polarity of the Battery Module. Doing so •
can increase the individual cell temperature and cause cell
rupture or leakage.

Never dispose of Battery Module in fire. Never short circuit •
the battery. The battery may explode, ignite, leak or get hot
causing serious personal injury.

Dispose of NiMH batteries according to national, state and •
local codes and regulations.

WAVEFORM SPECIFICATIONS

Interferential Current is a medium frequency waveform. Current is
distributed through two channels (four electrodes). The currents
cross each other in the body at the area requiring treatment.
The two currents interfere with each other at this crossing point,
resulting in a modulation of the intensity (the current intensity
increases and decreases at a regular frequency).

The Asymmetrical Biphasic waveform has a short pulse duration.
It is capable of strong stimulation of the nerve fibers in the skin
as well as of muscle tissue. This waveform is often used in TENS
