EMS CONTRAINDICATIONS
Powered muscle stimulators should not be used on people with cardiac demand pacemakers.
WARNINGS
• The long-term effects of chronic electrical stimulation are unknown.
• Stimulation should not be applied over the carotid sinus nerves, particularly in people with a known sensitivity to the
carotid sinus reex.
• Stimulation should not be applied over the 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 difculty in breathing.
• Stimulation should not be applied transthoracically in that the introduction of electrical current into the heart may cause
cardiac arrhythmias.
• Stimulation should not be applied transcerebrally.
• Stimulation should not be applied over swollen, infected, or inamed areas or skin eruptions, e.g., phlebitis,
thrombophlebitis, varicose veins, etc.
• Stimulation should not be applied over, or in proximity to, cancerous lesions.
PRECAUTIONS
• Safety of powered muscle stimulators for use during pregnancy has not been established.
• Caution should be used for people with suspected or diagnosed heart problems.

STEP BY STEP OPERATION GUIDE FOR TREATMENT
STEP 1 - Preparing Your Skin Before Using
Clean and dry treatment area so its free of all lotions, oils, and sweat. The electrode pad(s) should be applied only to
normal, intact, clean, healthy skin that is not experiencing any swelling or inammation.
Following the steps below can help prepare the skin for optimal electrical dispersion and increased stimulation
sensitivity.
1. Determine the electrode pad placement sites for the electrode pad(s).
2. Wash the area with mild soap and water (do not use alcohol). Rinse and dry thoroughly.
3. Trim excess body hair from the area with scissors (do not shave).
4. If desired, apply iReliev® Conductive Gel or Conductive Spray to help increase conductivity. This may also reduce the
chance of skin irritation and may extend the life of the electrode pads.
Note: It may be helpful to apply iReliev® After Use Electrotherapy Lotion on electrode pad placement area when system
is not in use to help increase moisture of skin.
Note: Pads are for single person use only.

TENS programs:
When using any of the 8 programs for pain relief, always start with the lowest intensity and gradually increase the level
of intensity until you feel a “tingling” sensation. All programs are different and therefore have a different sensation. You
may try all 8 programs in the beginning and choose one that feels pleasant. Never increase the intensity to a level so
that it hurts; always stay under the point of discomfort. Start with short sessions of 5 to 10 minutes until your body
gets used to the stimulation.
Program/Mode Benets You should feel

www.iReliev.com 19
Program/Mode You Should Feel & Benets Suggestion
P1
Exercise Prep
P1 gently warms up the muscles prior to exercise; it feels
like a rhythmic massage.
Increase intensity until you get a strong but
comfortable muscle movement; 10 min/duration.
P2
Muscle
Recovery
P2 produces muscle twitches at a very low frequency
and it feels like a tapping massage; for muscle recovery
from fatigue and becoming more relaxed with reduced
stiffness.
Use it after intense exercise to promote recovery and
relaxation; 30 min/duration.
P3
Active
Recovery
P3 is similar to P2, except that the muscle twitch rate
slows down during the session. It feels like a tapping mas-
sage, but softer than P2.
Use it after intense exercise to promote recovery and
relaxation; 20 min/duration.
P4
Active
Recovery
P4 activates the muscle in a short contraction/relaxation
cycle. It feels like a kneading massage, smoother than
P2/P3.
Use it after intense exercise to promote recovery and
relaxation; 20 min/duration.
P5
Build
Endurance
P5 uses a low frequency pulse which may favor slow
twitch bers, for potential development of aerobic ca-
pacity and capillary supply. It may help improve fatigue
resistance during long duration and moderate intensity
exercise.
The exercise comprises of an alternating sequence
of work and rest phases lasting several seconds.
Increase the intensity until you get a strong and deep
muscle contraction. Do not exceed your comfort level;
20min/duration.
P6
Muscle
Strengthening
P6 uses a pulse frequency appropriate to help fast
twitch muscle bers. It may help improve their anaerobic
capacity and may help improve muscle strength.
The exercise comprises of a sequence of work phases
separated by longer relaxation phases. Increase the
stimulation intensity until you get a strong and deep
contraction. Do not exceed your comfort level; 20 min/
duration.
EMS programs:
For muscle stimulation (EMS) any of the 6 programs may be used. The intent is to cause a muscle contraction, and
then release. All 6 programs will achieve contraction and vary by rate and duration of the contractions. Start out slowly
with low intensity levels for a warm-up (5-10 min). Increase intensity level and treatment time as you progress. Use the
device regularly or for longer sessions to achieve benets similar to passive “exercise”.
