INTRODUCTION TO TENS
What is Pain?
Pain is the body’s warning system. Pain is important because it signals an
unusual condition in the body and alerts us before additional damage or injury
can occur. TENS was developed to help relieve some types of chronic and acute
pain.
How does TENS work?
TENS is a method of treating pain that is non-invasive and does not use
pharmaceuticals.
The TENS device sends impulses through the skin that stimulate the nerve
(or nerves) in the treatment area. In many cases this stimulation will greatly
reduce or eliminate the pain sensation felt by masking the original pain
message sent to the brain.
It is also believed that TENS stimulation helps release endorphins into the
blood stream thereby further reducing pain.
TENS devices are clinically proven t o b e useful in pain management for
many patients. By reading this manual and carefully following the
treatment instructions given to you by your clinician, you can attain the
maximum benefit from your TENS device.

ABOUT THIS DEVICE
Your TENS device is a battery operated device that includes two controllable
output channels. This TENS device creates electrical impulses whose
amplitude, duration, and modulation can be altered with the controls or
switches. The TENS Intensity Controls are very easy to use, and the slide
cover protects accidental changes in settings.

6
UNIT CONTROLS
Panel Cover
A cover which conceals the controls for the Pulse Width, Pulse Rate, and Mode
Selector. Press the top portion of the cover and pull down in order to open the cover.
Intensity
The Intensity Knobs located on the top of the unit affect the strength of the
stimulation and also function as ON/OFF controls.
Mode
The Mode Switch is used to select the type of treatment utilized. The three
modes are Burst (B), Continuous (C), and Modulation (M).
Pulse Width
The Pulse Width Knob regulates the Pulse Width for both channels.
Pulse Rate
The Pulse Rate Knob regulates the number of pulses per second for both channels.
06
Mode Functions
Burst (B) releases individual bursts twice per second, Pulse Width is
adjustable and the Pulse Rate is set at 100Hz per second.
Continuous (C) stimulation is delivered continuously at the settings
determined by Intensity, Rate, and Width Knobs.
Modulation (M) Pulse Width decreases the Pulse Width down to 60% of the
original width setting. This decreased Pulse Width is maintained for 1.5
seconds before returning to the original width setting, which is maintained for
3.5 seconds. The cycle is then repeated. The Intensity and Pulse Rate are
adjustable.
ATTACHING THE LEAD WIRES
The lead wires provided with the TENS device insert into the ports located on
top of the unit. Holding the insulated portion of the connector, push the plug
end of the wire into one of the ports; one or two sets of the wires may be
used. After connecting the wires to the stimulator, attach each wire to an
electrode. Lead wires provided with the TENS device are compliant with
mandatory compliance standards set forth by FDA.
WARNING: Never insert the plug of the lead wire into an AC power
supply socket. Personal injury and/or damage to the TENS unit could occur.
CAUTION: Use care when plugging and unplugging the wires. Pulling on
the lead wire may cause wire breakage.

ELECTRODE SELECTION AND CARE
Use the electrodes as prescribed.
Follow application procedures outlined in electrode packaging to maintain
stimulation and prevent skin irritation. The electrode packaging provides
instructions for care, maintenance and proper storage of electrodes.
07
TIPS FOR SKIN CARE
Good skin care is important for effective and comfortable use of your TENS
device.
Always clean the electrode site with mild soap and water solution, rinse well
and dry thoroughly prior to any electrode application.
Any excess hair should be clipped, not shaved, to ensure good electrode
contact with the skin.
If a skin treatment is recommended by your physician, apply the skin
treatmentas recommended, let dry, and apply electrodes as directed.
Following these recommendations will both reduce the chance of skin
irritation and extend the life of your electrodes.
Avoid excessive stretching of the skin when applying electrodes. Proper
application is best accomplished by applying the electrode, then smoothly
pressing it in place from the center outward.
When removing electrodes, always remove by pulling in the direction of
hair growth.
It may be helpful to rub skin lotion on electrode placement area when not
wearing electrodes.
