Important Safety Information
• If your pain does not improve, becomes more than mild, or continues for more
than five days, stop using the device and consult with your physician.
• DO NOT place this device across your chest or near your heart because the
introduction of electrical current into the chest may cause rhythm disturbances
to your heart, which could be lethal.
• DO NOT place the pad near or on cancerous lesions, diseased skin, open
wounds, rashes, swollen, red, infected or inflamed areas or skin eruptions such
as phlebitis, thrombophlebitis and varicose veins.
• DO NOT place the pad over your neck because this could cause severe muscle
spasms resulting in closure of your airway, difficulty in breathing, or adverse
effects on heart rhythm or blood pressure.
• DO NOT place the pad on or near the head, mouth, face, heart or genitals.
• DO NOT use this device when bathing, showering, sleeping, during exercise, in
high humidity or rainy weather or if sweating.
• DO NOT apply stimulation while driving, operating machinery, or during any
activity in which electrical stimulation can put you at risk of injury.

device.
• Apply the pad ONLY to normal, intact, clean, healthy skin of adult patients.
• For Hospitals and Clinics: Operation in close proximity (e.g. 1 m) to a shortwave
or microwave therapy ME equipment may produce instability to the stimulator
output.
• For Hospitals and Clinics: Simultaneous connection of a patient to high
frequency surgical equipment and this device may result in burns at the site of
the stimulator electrodes and possible damage to the stimulator.

Important Safety Information
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury to the
user or patient, or cause damage to the equipment or
other property.
CAUTION
• TENS is not effective for pain of central origin, including headache.
• TENS is not a substitute for pain medications and other pain management
therapies.
• TENS devices have no curative value.
• 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
qualified in the management of pain patients.
• DO NOT use this device to treat 1 region for extended periods of time. The long-
term effects of electrical stimulation are unknown.
• If you experience any skin irritation or redness after a session, DO NOT continue
stimulation in that area of the skin.
• If you have suspected or diagnosed heart disease, you should follow precautions
recommended by your physician.
• If you have suspected or diagnosed epilepsy, you should follow precautions
recommended by your physician.
• DO NOT place the charger within 6 inches (approx. 15 cm) of any person who is
using a pacemaker or implantable cardioverter defibrillator (ICD). The charger
emits electromagnetic fields, which may affect pacemakers or ICDs.
Battery Handling and Usage
• To prevent the risk of overheating, fire or explosion:
- DO NOT puncture, crush, disassemble or modify the device.
- DO NOT throw the device into a fire.
- DO NOT recharge, use, or leave the device in high temperature locations near a
fire or in direct sunlight.
• The device contains a built-in rechargeable lithium-Ion battery which must be
disposed of properly. Dispose of the device according to applicable local
government regulations.

Important Safety Information
• Use caution if you have a tendency to bleed internally, such as following an
injury or fracture.
• Consult with your physician prior to using the device after a recent surgical
procedure because stimulation may disrupt the healing process.
• Use caution if stimulation is applied over the menstruating uterus.
• Use caution if stimulation is applied over areas of skin that lack normal
sensation.
• Use this device ONLY with components provided in the Focus packaging and
accessories recommended by the manufacturer. (Refer to sub-section 1.1 and
section 6)

• DO NOT overlap the adhesive surfaces of the pad or put them on top of each
other.
• DO NOT apply any lotion, cream or ointment to the pad.
• NEVER attempt to modify the device.
• The pad should not touch any metal object.
• To avoid damage to the adhesive surface of the pad, ONLY put the pad on the
skin or the plastic pad holder.
• ALWAYS place the clean pad in accordance with the illustrations provided (Refer
to sub-section 3.1).
• If the device is not functioning properly or you feel discomfort, immediately
stop using the device.

• DO NOT use the device when the band is damaged or the hook and loop
fasteners lose cohesion.
• When using the device, make sure that the hook and loop fastener does not
touch your clothing.
• While using this device, make sure that no mobile device or any other electrical
devices that emit electromagnetic fields is within 12 inches (30 cm). This may
result in poor performance of the device.

7
Important Safety Information
• DO NOT fasten the band too tight.
• DO NOT use this device if the adhesive surface of the pad is damaged.
• Ensure that this device has acclimated to room temperature before using.
Using this device after an extreme temperature change could lead to 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 specified 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 section 7.
Adverse Reactions
• You may experience skin irritation and burns beneath the stimulation electrodes
applied to your skin.

the application of electrical stimulation near your eyes and to your head and face.
• You should stop using the device and consult with your physician if you
experience adverse reactions from the device.

The OMRON Focus is a wearable, wireless TENS device that provides relief of
chronic, acute* and arthritic pain. Scientific 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 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.
Recommended Session Time
30 minutes per session is recommended.
2 sessions per day at maximum is recommended.
* Acute pain refers to sore or achy muscles due to strain from exercise or normal household
and work activities
