vice Directive
The QuadStar® II is a unique Electrotherapy system incor-
porating the following:
• Three modalities- T.E.N.S. (Transcutaneous Electrical Nerve
Stimulation), N.M.S. (NeuroMuscular Stimulation), and I.N.F.
(Interferential Stimulation)
• Three waveforms- Symmetrical Biphasic Square Wave,
Asymmetrical Biphasic Square Wave, and a Pulsed Sine
Wave.
• Four channels allowing the use of up to eight electrodes at
a time
• Pre-programmed and programmable functions
• “Sequential Stimulation” enabling the user to sequence two
or more modalities for complete treatment
• Patient Lock/Compliance System: enables the practitio-
ner/physician to lock the parameters for ease of use for the
patient, and monitor hours of use.
• Timer - to time treatments
• Comes ready to use, with all accessories, and is powered
by 4 AA batteries or Wall Adapter.
This booklet gives the health practitioner/physician an
overview of the QuadStar®II device functions. This informa-
tion is offered in condensed format; should you have further
questions, please consult your health practitioner or physical
therapist.
The amplitude, pulse rate, pulse width and the mode selec-
tors operate independently of each other, but interact to
achieve the desired result. As individual syndromes differ,
the controls are adjusted to a setting which gives optimal
comfort and pain relief.
Amplitude: The amplitude controls the intensity and the
depth of the pulse. The higher the amplitude, the higher the
pulse peak and the stronger the pulse. If the electrodes are
placed over scar or over adipose tissue, care should be taken
that the amplitude is set at a level that is both effective for
the patient’s treatment and does not cause the patient any
discomfort. Set the QuadStar® II amplitude to the appropri-
ate level according to patient comfort. There is no benet to
painful stimulation.
Pulse Width: The pulse width governs the width of the pulse.
A comfortable sensation covering the injured area is the
main purpose of the pulse width. The pulse width has been
xed (preset) in the QuadStar® II Interferential Modality.
Pulse Rate: The pulse rate controls the number of pulses
emitted through the electrode to the skin.
The pulse rate is also referred to as:
1. Frequency
2. Cycles per second (c.p.s.)
3. Pulses per second (p.p.s.)
A Hertz (Hz) is a unit of frequency equal to one pulse per
second, e.g. 50 Hertz = 50 p.p.s
INTERFERENTIAL OPERATING INSTRUCTIONS:
Turn on the device by pressing the power key (12).
If it is the rst time you have turned the device on, the

INTERFERENTIAL OPTIONS:
Frequency or “Hz”: 1-150. This is the desired “beat fre-
quency”
Two or Four Channels:
If two channels are chosen, each channel works indepen-
dently and the beat frequency is mixed inside the unit. This
is also known as “pre modulated” stimulation. The user
can choose to utilize only one channel by choosing pre
modulated stimulation and turning up the amplitude on the
channel(s) (1 or 3).
If four channels are chosen, channels 1 & 2 and channels 3
& 4 work together as a pair, and the beat frequency is cre-
ated when the two waveforms mix inside of the body. The
user can choose to use only one interferential pair by turning
up the amplitude only on channels 1 & 2 only or 3 & 4 only.

INTRODUCTION TO MUSCLE STIMULATION (NMS)
Electrical Muscle Stimulation (EMS) or Neuromuscular Stim-
ulation (NMS) is the use of electrical stimulation on muscle
groups to contract and reeducate muscles. Some of the
uses of EMS are as follows:
1. The Prevention or Retardation of Muscle Disuse Atrophy:
Muscle disuse atrophy is a reduction in muscle contraction
and size due to disuse/lack of use resulting from prolonged
impairment or joint immobility from surgery, injury.
2. Relaxation of Muscle Spasms:
Muscle spasms often occur in areas of localized pain and
tenderness. Stimulation is used to fatigue the spasmodic
muscle.
3. Increasing Local Blood Circulation
Rhythmic muscle contraction helps improve local blood cir-
culation.
4. Immediate Postsurgical Stimulation of Calf Muscles to
Prevent Venous Thrombosis.
The use of NMS or EMS to increase local blood circulation
assists in the prevention of venous thrombosis.

SEQUENTIAL STIMULATION
FIXED SEQUENTIAL PROGRAMS
The QuadStar® II has 9 xed sequential stimulation pat-
terns. The xed patterns cannot be altered, each is a
preset sequential stimulation pattern (See the following
section on programming sequential stimulation.)
To choose a xed sequential treatment press the "Left Ar-
row Key" (6) and use the “Up and Down Arrows”(5) and
(9) to toggle to "Seq" when "Seq" blinks press the "Enter
Key" (7) to choose sequential stimulation. "Fixed Seq. 1"
blinks, if you wish to choose this sequence, press the "En-
ter Key" (7). If another xed sequence is desired, press
the "Down Key" (9) to scroll through the nine xed se-
quence, pressing the "Enter Key" (7) when the desired se-
quence blinks. When the desired sequence is chosen, the
screen will display the rst part of the sequence to show
the practitioner the settings for the sequence. When the
electrodes are placed, the device is ready to begin stimu-
lation. Use the "Intensity Selector Keys" (1-4) to begin
stimulation and set the device to the desired intensity.
Once the rst modality in the xed sequence is nished,
the device will stop stimulation and the word "Start" will
blink at the top of the screen. Once the "Enter Key" (7)
is pressed, the device will begin the second part of the
sequence. Again use the "Intensity Selector Keys" (1-4) to
begin stimulation and set desired intensity for the current
modality. Repeat steps for the third modality.
*Each part of the sequence runs for 20 minutes.

BATTERIES:
In order to maintain the functional operation of the
QuadStar®II the batteries will have to be changed periodi-
cally. The device is supplied with 4 AA Alkaline batteries.
When batteries are running low, a battery image will appear
and ash on the bottom right hand corner of the display
screen (C). When this image appears, the batteries should
be changed to ensure maximum performance.
Warning: We do not recommend the use of rechargeable
batteries, as they may weaken the performance and/or
readout of the device.
To change batteries:
• Before opening the battery compartment, check to make
sure that the device is switched off.
• Slide open the battery compartment cover.
• Remove the batteries from the compartment. Gently insert
the new batteries by matching the +/– end of each battery
with the +/– symbol found inside the battery compart-
ment.
• Slide the battery cover to the closed position.
• Remove the batteries if you do not plan to use the
device for long periods of time. Otherwise leakage and

damage to the device can occur.
• Dispose of batteries in a proper manner.
Safety and Technical Checks
Once a year, a maintenance check should be performed on
the device as follows:
• Visually check the exterior case of the device for dam-
age.
• Visually check the input and output sockets for damage.
• Visually check the device for clarity of reading instruc-
tions and indicator decals.
• Visually check that the symbols of the LCD are operating
correctly.
• Visually check the lead wires and electrodes for damage
MALFUNCTIONS:
Should any malfunctions occur while using this device,
check:
• Whether the lead wires and electrodes are correctly con-
nected to the device. The lead wires should be inserted
rmly into the device sockets.
• For possible damage to the lead wires. Change the lead
wires if any damage is detected.
During use the surface of the QuadStar II may get warm.
This is normal, due to the high level of therapeutic
power being produced. This unit fully complies with
the requirement that under normal use the temperature
never exceed that allowed by law. If an unusual situa-
tion occurs (for example, electrodes touching each other
or insufcient air clearance around the unit) the unit will
automatically shut down in order to prevent excessive
heating. If this should occur, nd and correct the reason
for the shutdown, allow the unit to cool for a few min-
utes, and then turn it on in the normal manner. If the
unit does not turn on, the unit is not cool enough, and
more cooling time will be necessary.
Do not attempt to repair a device yourself!

Indications
Transcutaneous Electrical Nerve Stimulation (TENS)/In-
terefential devices are used for the symptomatic relief and
management of chronic (long-term) intractable pain and as
an adjunctive treatment in the management of post-surgical
and post-traumatic acute pain problems.
External electrical neuromuscular stimulation using bi-phasic
output is indicated as therapeutic adjunct for prevention or
retardation of muscle disuse atrophy; relaxation of muscle
spasm; muscle reeducation; maintaining and increasing the
range of motion; increasing local blood circulation and as
an immediate post-surgical stimulation of calf muscles to
prevent venous thrombosis.
Contraindications
TENS & EMS/NMS devices can adversely affect the opera-
tion of demand-type cardiac pacemakers. TENS & EMS/NMS
is not recommended for patients with known heart disease
without a physician’s evaluation of risk. Do not stimulate
over the eyes or carotid sinus nerves as severe spasm of
the laryngeal and/or pharyngeal muscles may occur when
electrodes are placed over the neck or mouth. (These con-
tractions may be strong enough to close the airway or cause
difculty in breathing.) Do not apply TENS & EMS/NMS for
un-diagnosed pain syndromes until etiology is established.
Do not place electrodes in a manner that causes current to
ow trans cerebrally (through the head). TENS & EMS/NMS
devices should not be applied to malignant tumors.
Warnings
This device should be used only under the continued supervi-
sion of a physician, or outside the USA, by a qualied pain
management specialist. TENS/Interferential stimulation is
ineffective for pain of central origin (i.e. appendicitis, hepati-
tis). TENS/Interferential stimulation is of no curative value; it
is a symptomatic treatment which suppresses pain sensation
which would otherwise serve as a protective mechanism on
the outcome of the clinical process. Safety of TENS/Interfer-
ential devices for use during pregnancy or delivery has not
been established. For external use only. Electronic equip-
ment such as EKG monitors and EKG alarms may not operate
properly when TENS/Interferential Stimulation is in use.
This device should not be used over metal implants or sleep
apnea monitors.
Adequate precaution should be taken when treating patients
with suspected heart problems or epilepsy. Caution should
be exercised in the trans thoracic application of EMS devices
so that the introduction of electrical current into the heart
does not cause arrhythmia. The long-term effects of chronic
electrical stimulation are unknown.
Persistent use of stimulation in the presence of skin irrita-
tion may be injurious. Stimulation should not be applied over
swollen, infected, or inamed areas or skin eruptions, e.g.,
phlebitis, thrombophlebitis, varicose veins, etc. Simultane-
ous connection to RF surgery equipment can cause a burn.
Operation near (e.g. 1m) short wave or micro wave therapy
equipment can change the output values of the stimulator.
EQUIPMENT not suitable for use in the presence of a
FLAMMABLE ANESTHETIC MIXTURE WITH AIR OR WITH
OXYGEN OR NITROUS OXIDE
PRECAUTIONS:
Skin irritation may occur under electrodes in isolated cases
following long-term application. Consult physician if skin ir-
ritation develops. The effectiveness of TENS & EMS/NMS/In-
terferential Stimulation directly depends upon patient selec-
tion. Use only for the specic pain problem prescribed by the
physician. Do not immerse device in water or other liquids.
Electrode placement and stimulation settings should be
based on the guidance of the prescribing practitioner. Turn
the stimulator off before applying or removing electrodes.
Powered TENS/EMS/NMS/Interferential devices should be
used only with leads and electrodes recommended for use by
the manufacturer and should not be used while driving, op-
erating machinery, or during any activity in which involuntary
muscle contractions may put the user at undue risk of injury.
The device may be affected by electromagnetic interference.
Also other electrical equipment in the close vicinity may be
affected by the device. If such effects are suspected, either
switch off the affected equipment and that suspected of
causing the interference, or shorten connecting leads.
Precaution should be exercised when stimulation is used:
-After recent surgical procedure where muscle contraction
may disrupt the healing process.
-After an acute trauma or fracture where there is a ten-
dency to hemorrhage;
-Over the menstruating uterus;
-Where the sensory nerve damage has caused the loss of
normal skin sensation
Adverse Reactions
Possible allergic reaction to tape or gel. Possible skin irrita-
tion or electrode burn under electrode. Be sure to follow
the instructions of your health professional. If you do have
questions or problems make sure you contact them for as-
sistance.
