4. IMPORTANT SAFETY PRECAUTIONS AND WARNINGS
WARNING
Indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
DONOTUSETHISUNITWITHTHESEOTHERDEVICES:
• Donotuse this device whileusinganotherTENS device.
• Together with a life-supportingmedicalelectronicdevice such as an articial heart or
lung or respirator.

GeneralPrecautions
• 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 qualied in the
management of pain patients.
• Youmayexperienceskinirritationorhypersensitivity due to the electrical stimulation or
electrical conductive medium (gel).
•
Keepunitawayfromyoungchildren. The unit contains small pieces that may be swallowed.
Immediately contact your physician.
• Ensure that this device has acclimated to room temperature before using. Using this
device after an extreme temperature change could lead to an improper operation. OMRON
recommends waiting for approximately 2 hours for the device to warm up or cool down
when the device is used in an environment within the temperature specied as operating
conditions after it is stored either at the maximum or at the minimum storage temperature.
For additional information of operating and storage/transport temperature, refer to
“SPECIFICATIONS”.

5. HOW POCKET PAIN PRO WORKS
Whatisit?
TheOMRONPocketPainProisaportabledevicethatrelieveschronic,acute*andarthritic
painthroughthepainreliefofTENS. It is designed to reduce and relieve muscle and joint pain,
stiffness and numbness in the back, arms, legs, shoulder and foot by applying electrical nerve
stimulation to the surface of the skin near the site of the pain. Anyofthemodescansafelybeused
onbodypartsorpainsdescribedinthismanualorthe QuickStartGuide/PadPlacement
Guide. This device can be used in conjunction with any other pain treatment or medication.
TENS (Transcutaneous Electrical Nerve Stimulation) has been used for over 40 years by medical
professionals such as physical therapists and chiropractors.
* Acute pain refers to sore or achy muscles due to strain from exercise or normal household
and work activities
Howdoesitwork?
Scientic theory suggests that electrical stimulation therapy may work in several ways:
1. The 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. The gentle electrical pulses increase the production of the body’s natural pain killer,
such as endorphins.
3. The electrical stimulation improves blood circulation. Muscles contract and relax with
the ow of the electrical stimulation. With repeated contracting and relaxing, the blood
ows in and out and the blood circulation is improved.

8. GET STARTED WITH YOUR THERAPY

23
Whenshouldyoustarttherapy?
Use as soon as your pain begins. Start with one session (the unit automatically turns off at 15
minutes). Turn off with pads still on and rate your pain again (1 low to 10 high).
Gettoyourpainearly
If you get to your pain early, it may prevent the pain from becoming worse, or even chronic.
It’s better for you to get it under
control sooner so that it does not reach a high pain threshold where it limits your daily
activities.
Howlongshouldyouuseit?
Start with one 15-minute session. Always turn the unit off with the pads still on. Rate your
pain to check your progress, 1 low to 10 high. Stop your therapy session if pain has reduced or
stopped. Press the Power button to continue therapy for another 15-minute session.

CAUTION
• Excessive treatment and strong stimulation may cause muscular fatigue and may generate
adverse effects.
Whentostopusingtheunit?
1. If you experience an adversereaction (skin irritation/redness/burns, headache or other
painful sensation, or if you feel any unusual discomfort).
2. If your pain doesnotimprove, becomes seriously chronic and severe, or continues for
morethanvedays.
9. HOW TO CONTROL AND REDUCE YOUR PAIN

24
Whattypeofpainisitbestfor?
This therapy works best on acute pain because it is localized. Acute pain is pain in one area
for less than 3 months. If you have chronic pain, you may have pain in more than one area
and for longer than 6 months. Chronic pain may be compounded by other issues that this
unit cannot address.
Remember, this unit does not cure your pain or the original cause of the pain. It provides
temporary relief or reduction of pain so that you can control your life and activities better.
Beforeusing,checktomakesureallcomponentsareworkingproperly.
1. Make sure the cord is not broken.
2. Check that the pad adhesive sticks and is not damaged.
3. The electrode cord connection is not broken.
4. The unit is intact and in working order.

The life of the pads may vary by how often you wash the pads, the skin condition, and how
you store the pads.
Whenshouldyoureplaceyourpads?
If the pad no longer sticks to your skin or if more than 25 % of the pad’s surface is not in
contact with your skin.
Cleaningtheunit
1. Turn the unit off and disconnect the electrode cords from the pads.
2. Clean with a lightly moistened cloth (or a cloth soaked in a neutral cleaning solution) and
wipe gently.
• Do not use chemicals (like thinner, benzene).
• Do not let water get into the internal area.

Storingthepads
1. Turn the unit off and remove the cord from the bottom of the unit.
2. Remove the pads from your body.
3. Leavetheelectrodecordsconnectedtothepads.
Place the pads on the pad holder, one pad on each side with the
sticky side of each pad on the pad holder.
4. Wraptheelectrodecordsaroundthepadholder.
Storingtheunitandpads
• Place the unit, pads with electrode cords on pad holder, Pad Placement Guide and
Instruction Manual inside the original box.
• Do not keep in areas subject to direct sunlight, high or low temperatures, humid area, near
to re, vibration, or shock.
Storage temperature, 32 °F - 104 °F (0 °C - 40 °C), 30 % - 80 %
relative humidity.
• Donotkeepinplacesthatcanbeeasilyreachedbychildren.
• When not in use for a long period, remove the batteries before storage
to avoid liquid discharge from batteries.
• Do not wrap the electrode cords around the unit because it may damage
the cord.
