2000-T TENS 2
INTRODuCTION
Indications
This device is restricted to sale or use by or on
the order of a physician licensed in the state in
which he or she is practicing. It is to be used
solely for the symptomatic relief of chronic intractable pain.
Contraindications
1. Do not place the TENS electrodes over the
carotid artery (neck) region.
2. Patients with implanted electronic devices
(for example, a pacemaker) or metallic implants should not undergo TENS treatment
without rst consulting a physician.
3. Do not apply the TENS electrodes so that
current passes transcerebrally (through the
head).
4. The use of TENS whenever pain symptoms are
undiagnosed and the etiology has not been
established.
To the Patient
You have been diagnosed as having a type of pain
discomfort that may be alleviated by the use of
transcutaneous electrical nerve stimulation. The
2000-T TENS 3
2000-T generates electrical pulses that are sent
through the electrodes which are placed over
nerve centers. The various pulses employed by
2000-T can block pain signals normally sent to
the brain through nerve bers, thereby interrupting the brain’s awareness of pain. The 2000-T
may activate the release of endorphins which
are chemicals used by the body to suppress pain
naturally.
Transcutaneous Electrical Nerve Stimulation
(TENS) is:
- Safe.
- Non-invasive.
- Non-pharmaceutical.
- Non-addictive.
Many clinical studies have shown the effectiveness of TENS for the relief of pain. Your 2000-T
can reduce the need for pharmaceuticals if used
as prescribed by your physician. Abide by the
warnings and contraindications listed in this
manual when undergoing TENS treatment.

INSTRuCTIONS fOR uSING ThE 2000-T
1. The ON/OFF switches are the amplitude control
knobs located on the top of the unit. There are
two amplitude control knobs: Channel 1 and
Channel 2. The unit is set to the OFF position
when this knob is set to 0. If one of the knobs is
set to a position other than 0, the corresponding channel is currently in the ON position.
The amplitude increases in intensity as the
control knob is moved from 1 to 8. Each channel
operates independently from the other. Turning ON one channel gives a steady fast ashing
yellow power indicator light located next to
the channel. A green light located between the
two amplitude control knobs will light up when
the unit is in the ON position. A weak battery is
indicated when this light becomes dim.
2000-T TENS 8
2. Set the Pulse Frequency Control. This regulates the frequency of the pulses from 2 to 120
pulses per second (pps or Hz).
3. Set the Pulse Width Control. This regulates
the width (duration) of each pulse from 40 to
260 micro seconds.
4. Set the Mode Selector Switch to one of the
three modes of stimulation:
M Modulation Mode: This mode cycles every
4 seconds. The pulse width and frequency
remain adjustable.
B Burst Mode: This mode produces two
bursts of pulses every second. Each burst
has 7 pulses; each pulse at the 100Hz rate.
The pulse width remains adjustable.
N Normal Mode: This mode provides a
steady stream of pulses. The pulse width
and pulse frequency remain adjustable.
5. Setting the Pulse Width and Pulse Frequency:
a. Conventional settings: set the pulse width
to 90 to 100 microseconds.
b. Low rate settings: Set the pulse width to
200 to 220 microseconds. Set the pulse
frequency to 2 to 4 Hz.
c. Brief intensity settings: Set the pulse width
to 200 to 250 microseconds.

6. Holding the insulated portion of the lead wire
plug, push the plug into one of the channel
output ports located on the top of the unit;
one or two sets of wires may be used. (The
lead wires have one end which inserts into
the electrodes and one end which inserts into
the channel output port.)
7. Batteries: Use
ONLY 9V or 9V rechargeable
NiCad batteries with this unit.
s
Caution: Effectiveness of TENS treatment is
highly dependent upon patient selection by a
qualified physician.

uSING ELECTRODES:
To maximize comfort while using electrodes the
following measures are recommended:
1. Before applying or removing electrodes turn
the unit to the OFF position using the Amplitude Control Knobs.
2. Read and follow the instructions for use for
the electrodes utilized.
3. Place the electrode onto the skin over the
desired nerve ber region. Note: If a component of the electrode is not afxed to the skin
a tingling sensation may occur at the spot of
poor contact which may cause discomfort. Be
sure the entire electrode is rmly in place.
4. Insert the lead wire into the Channel Output
Receptacle after the electrode is applied.
Suggestions:
Never remove an electrode while the unit is in
the ON position. This may cause an uncomfortable tingling sensation to occur.
Never disconnect either end of a wire lead by
pulling on the wire. Disconnect the lead wire by
holding the insulated portion of the lead wire
end.

s
Caution: Skin irritation may occur at the electrode site following long-term application.
SkIN CaRE:
To reduce the chance of skin irritation, the following is recommended:
1. Closely clip or shave hair before applying an
electrode to encourage better contact and
connectivity between the skin and the electrode.
2. Only apply clean electrodes to clean dry skin.
3. Firmly press the electrode onto the skin to ensure complete contact is achieved. If a component of the electrode is not afxed to the skin
a tingling sensation may occur at the spot of
poor contact which may cause discomfort.
4. When removing the electrode, pull GENTLY on
the electrode.
5. Do not apply an electrode over broken skin as
this may produce discomfort.
6. When applying an electrode, do not allow the
skin or the electrode to be stretched.
s
Caution: Improper application of electrodes
or TENS settings my cause electrode burns.
Use the TENS unit as directed by your physician.

CaRING fOR ThE 2000-T
1. When not in use, store the 2000-T in the case
provided to protect it from external damage.
2. Make sure the electrode and the skin are both clean.
3. Firmly press the electrode onto the skin to
ensure complete surface contact is achieved.
If a component of the electrode is not afxed
to the skin a tingling sensation may occur at
the spot of poor contact which may cause
discomfort.
4. When removing the electrode, pull GENTLY on
the electrode.
5. Do not apply an electrode over broken skin as
this my produce discomfort.
6. When applying an electrode, do no allow the
skin or the electrode to be stretched.
7. The 2000-T may be cleaned by wiping it
gently with a damp cloth moistened with mild
soap and water. Never immerse the device in
water or other liquids. The lead wires may be
cleaned with a damp cloth moistened with
soap and water.
s
Caution: Improper application of electrodes
or TENS settings my cause electrode burns.
Use the TENS unit as directed by your physician.
2000-T TENS 13
TROuBLEShOOTING:
If the TENS unit does not function properly:
1. Make sure the battery is properly installed or
replace the battery.
2. If the Channel Amplitude knobs are turned to
the OFF position and there is a light blinking
or glowing do not use the unit. Contact an
authorized GF Health Products, Inc. representative.
3. If the Channel Amplitude knobs are turned to
the OFF position and any stimulation is felt
do not use the unit. Contact an authorized GF
Health Products, Inc. representative.
4. If the lights are functioning correctly and no
stimulation is felt, check to ensure the lead
wires are properly connected and the electrodes are in place. If the unit appears to be
functioning and no stimulation is felt, the lead
wires or electrodes may need to be replaced.
5. If any problems occur, contact an authorized
GF Health Products, Inc. representative. Do
not try to repair the unit.
Note: The life of a NiCad battery is about 12% as
long as the life of an alkaline battery. At a medium
setting, the battery life of an alkaline battery will
be approximately 75 hours.
