PRECAUTIONS REGARDING THE PADS
•
Do not move the pads to another location while the unit is on.
• Therapy won’t work with just one pad. You MUST USE TWO PADS at the same time.
• Make sure the components are connected well and the pads are xed on the part of
the body you wish to treat or the therapy may not be effective.
• Pad should not touch any metal object, such as a belt buckle, necklace, or other metal
worn under clothing.
• Do not overlap pads or put pads on top of each other.
Gel pads may also stick together and cause gel to be removed when separating.
• Do not share pads with another person. This may cause a skin irritation or infection.
Pads are intended for use by one person.
• Do not leave pads attached to the skin after treatment.
4. IMPORTANT SAFETY PRECAUTIONS AND WARNINGS

• Do not bend or fold the pads because the gel may get damaged and it won’t stick or
function properly.
• To avoid damage to the adhesive surface of the pads, put the pads only on the skin or
on the plastic pad holder provided.
• Always place clean pads in accordance with illustrations provided (Refer to pages
19-22, Pad Placement).
• Do not apply ointment or any solvent to the pads or to your skin because it will disrupt
the pads from functioning properly. The self-adhesive pads will adhere to your skin.
• Do not add spray, lotions or creams to skin or pads.
• Place pads on each side of the pain, not directly on the pain.
• Place pads at least 1 inch (3 cm) apart for optimal results.

General Precautions
• The long-term effects of electrical stimulation are unknown.
• Apply stimulation to only normal, intact, clean, dry and healthy skin.
• TENS is not effective in treating the original source or cause of the pain, including headache.
• TENS is not a substitute for pain medications and other pain management therapies.
• TENS devices do not cure disease or injuries.
• TENS is a symptomatic treatment and, as such, suppresses the sensation of pain that
would otherwise serve as a protective mechanism.
• Effectiveness is highly dependent upon patient selection by a practitioner qualied in the
management of pain patients.
• You may experience skin irritation or hypersensitivity due to the electrical stimulation
or electrical conductive medium (gel).
• Keep unit away from young children. The unit contains small pieces that may be swallowed.

5. HOW MAX POWER RELIEF WORKS
How does it work?
The OMRON Max Power Relief is a powerful TENS device that provides relief of chronic,
acute* and arthritic pain.
Scientic theory suggests that TENS therapy may work in several ways:
1. Gentle electrical pulses move through the skin to nearby nerves to block or shut out
the pain message from ever reaching the brain from the source of the pain.
2. Gentle electrical pulses increase the production of the body’s natural pain killers,
such as endorphins.
3. Blood circulation improves as muscles contract and relax with the ow of the
electrical stimulation.
* Acute pain refers to sore or achy muscles due to strain from exercise or normal household and work activities.
