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

Use the Constant Mode or a
Pulse Rate greater than 60 Hz.
for the relaxation of muscle
spasms only. Use of continuous
stimulation and/or rates above
the normal physiological range
(e.g., greater than 60 Hz) could
lead to rapid onset of muscle
fatigue, making the device less
effective in producing repeated
forceful muscle contractions.

We herewith declare that the
above mentioned product meets
the provisions of the Medical De-
vice Directive
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 benefit 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
fixed (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 first time you have turned the device on, the
"Menu" Screen appears and INF is blinking. If the "Menu"
screen does not appear, press the "Left Arrow Key" (6) to ac-
cess it. To choose the INF (Interferential) Modality press the
Enter Key (7) to select it.
To select another modality press the down key (9) to scroll
until the desired modality blinks and press the Enter Key (7)
to select it. (Refer to section on desired modality for further
instruction).
When INF is selected a sub menu appears displaying
"CONST" and "SW"
CONST = Constant Stimulation
SW= a pre programmed Sweep mode. There are three pre
programmed sweeps in the INF mode. Press the down key
(9) to scroll through them. Press the Enter Key (7) when the
desired mode blinks.
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.
Timer: If timed treatment is desired, press the Timer Key
(11) and use the Up and Down Arrows (5 & 7) to set the
desired time from 1-99 minutes. The unit will automatically
shut off when the timer hits "0 min"
CONST: If Constant stimulation is chosen, the value for "Hz"
is blinking. Use the Up and Down Keys (5) and (9) to set the
desired amount and then press the Enter Key (7).
Next, the device prompts the user to choose 2 or 4 channels.
Use the Up and Down Keys (5 & 7) to change the graphic to
represent the desired amount of electrodes to be used.
Press the timer key (11) and "0" min blinks. Press the
Up/Down arrows (5) and (9) to set the desired amount of
minutes 1-99.
Use the amplitude keys (1-4) to turn up the amplitude and
begin stimulation, turn up the amplitude one at a time. The
unit will not turn up if you press two or more keys at the
same time.
SW1: If Sweep 1 is chosen, the value for "Hz" is blinking
1-10 to demonstrate the beat frequency will sweep between
1-10. Sweep 1 is used for edema reduction. This is a preset
sweep and cannot be changed.
Next, the device prompts the user to choose 2 or 4 channels.
Use the Up and Down Keys (5 & 7) to change the graphic to
represent the desired amount of electrodes to be used.
Press the timer key (11) and "0" min blinks. Press the
Up/Down arrows (5) and (9) to set the desired amount of
minutes 1-99.
Use the amplitude keys (1-4) to turn up the amplitude and
begin stimulation, turn up the amplitude one at a time. The
unit will not turn up if you press two or more keys at the
same time.
