Letter to the Patient
Your physician has prescribed the Avid IF2™ as part of your treatment plan.
The Avid IF2 is an interferential stimulator. It will help reduce pain and
other symptoms of your condition.
The Avid IF2 sends small pulses of current through electrodes* on your
skin. These pulses pass through the skin and activate nerves. The Avid IF2
activates sensory nerves at low levels. This causes a tingling sensation
and helps with pain. Motor nerves are activated at higher levels. This
helps increase circulation.
Always follow the instructions of your physician to get the most out
of your treatment. He or she knows your specific condition and the
Avid IF2 settings. He or she will instruct you on the proper settings for your
individual condition.
If you have any questions about the Avid IF2 or need any assistance
in setting up or maintaining this equipment, or to report unexpected
operations or events, contact VQ OrthoCare at 800.452.7993.
NOTE: The Avid IF2 is not a substitute for full medical evaluation and
treatment. Talk to your physician or therapist if you have any questions
about the Avid IF2 or your treatment plan. The Avid IF2 should only be
used by the person for whom it is prescribed.
* For use only with stimulating electrodes, commonly referred to as “electrodes” throughout this manual

CAUTION: Federal law restricts this device to sale by, or on the order of,
a practitioner licensed by the law of the State in which he/she practices
to use or order the use of this device.
NOTE: Please read the following prescription information carefully before
using the Avid IF2™. If you have any questions regarding this information,
consult with your physician or therapist before proceeding.
Interferential Stimulation can be used in the following applications:
• Symptomatic relief of post surgical and/or post traumatic acute pain
• Symptomatic relief of chronic intractable pain
• Relaxation of muscle spasms
• Maintaining and increasing range of motion
• Increasing local blood circulation
CONTRAINDICATION:
Stimulators should not be used on patients with cardiac demand pacemakers.
WARNINGS:
• The long-term eects of chronic electrical stimulation are unknown.
• Stimulation should not be applied over the carotid sinus nerves, particularly
in patients with a known sensitivity to the carotid sinus reflex.
• 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 diculty in breathing
• Stimulation should not be applied directly on the eyes.
• Electrodes should not be placed on the chest in such a configuration that
would allow electrical current delivered by the device to flow through the
chest because it may cause a cardiac arrhythmia.
• Stimulation should not be applied transcerebrally.
• Stimulation should not be applied over swollen, infected, or inflamed areas
or skin eruptions, e.g. phlebitis, thrombophlebitis, varicose veins, etc.
• Stimulation should not be applied over, or in proximity to, cancerous lesions.
• Due to the potential for causing skin burns, this device should only be used
with electrodes which limit the current density to 0.25W/cm2
Precautions & Prescription Information

Avid IF2 Patient Manual | 5
ENGLISH
WARNINGS CONT.:
• Stimulation should not be applied transthoracically in that the introduction
of electrical current may cause cardiac arrhythmias.
• Simultaneous connection of a patient to a high frequency surgical medical
electronic equipment may result in burns at the site of the stimulator
electrodes and possibly damage to the Avid IF2.
• Application of electrodes near the thorax may increase the risk of cardiac
fibrillation.
• Any electrodes that have current densities exceeding 2mA/cmmay require
the special attention of the operator.
PRECAUTIONS:
• Safety of stimulators for use during pregnancy has not been established.
• Caution should be used for patients with suspected or diagnosed heart
problems.
• Stimulation should not be applied across or through the head, directly
on the eyes, covering the mouth, on the front of the neck (especially the
carotid sinus), or from electrodes placed directly on the chest and upper
back or crossing over the heart.
• Caution should be used for patients with suspected or diagnosed epilepsy.
• Caution should be used in the presence of the following:
- When there is a tendency to hemorrhage following acute trauma or
fracture
- Following recent surgical procedures when muscle contraction may
disrupt the healing process
- Over the menstruating or pregnant uterus
- Over areas of the skin which lack normal sensation
• Some patients may experience skin irritation or hypersensitivity due to
electrical stimulation or electrical conductive medium. The irritation can
usually be reduced by using an alternative conductive medium or alternate
electrode placement.
• Electrode placement and stimulation setting should be based on the
guidance of the prescribing practitioner.
• Keep out of the reach of children.
• Keep lead wires away from children; the length of the lead wire could cause
entanglement of a baby or small child, potentially causing strangulation.

6 | Avid IF2 Patient Manual
ENGLISH
PRECAUTIONS CONT.:
• Use only with the lead wires and electrodes recommended for use by
the manufacturer.
• Portable stimulators should not be used while driving, operating machinery,
or during any activity in which involuntary muscle contractions may put the
user at undue risk of injury.
• Do not trim electrodes as cut edges may aect even distribution of
stimulation.
• Do not immerse electrodes in water.
• Electronic monitoring equipment (such as ECG monitors and ECG alarms)
may not operate properly when the Avid IF2 is in use.
• Wireless communications equipment such as wireless home network
devices, mobile phones, cordless telephones and their base stations,
walkie-talkies can aect the Avid IF2 and should be kept at least 1 (one)
meter away from the equipment. In addition, the presence of RFID and
security systems (e.g., electromagnetic anti-theft systems, and metal
detectors) might interfere with the operation of the Avid IF2 stimulator.
ADVERSE REACTIONS:
Skin irritation and burns beneath the electrodes have occasionally been
reported with the use of electrical stimulators.
If you experience any symptoms of skin irritation or any unusual reactions while
using the Avid IF2, discontinue use immediately and contact VQ OrthoCare’s
Patient Care Department at 800.452.7993 or consult your physician.

CAUTION:
DO NOT apply lotions, oils or other ointments to the skin prior to the application
of electrodes. Topical agents may increase the risk of skin irritation.
DO NOT clean the skin with anything other than soap and water. Other cleaning
agents may interfere with proper conduction.
USE OF electrodes smaller than 2” round or 2x2” square is not recommended
as increased power density could cause skin irritation or burn.
USE OF electrodes for long periods of time without removal may cause skin
irritation.
In the event of skin irritation, discontinue use immediately and contact VQ OrthoCare’s
Patient Care Department at 800.452.7993 or consult your physician or therapist.
Starting Your Treatment Sessions
1. Prepare the skin. Electrode application sites must be clean, dry, unbroken
skin surfaces. To reduce the risk of skin irritation, follow these instructions
for proper skin care before treatment.
^Wash site of electrode placement with mild soap and water before
applying electrodes.
^Rinse all soap o the skin before continuing.
^Dry the skin thoroughly.
^Trim excess body hair from electrode sites with scissors. Be
careful not to cut (or break) the skin. DO NOT SHAVE THE SKIN
IMMEDIATELY PRIOR TO STIMULATION. Shaving will create small
cuts in the surface layer of skin.
2. Inspect each electrode and lead wire before application. Do not
proceed if there is any doubt about the integrity or proper function of any
electrode or lead wire. Connect the lead wire to the electrodes. Make
sure there is no bare metal exposed at the connection points. Do not
use unnecessary force in connecting the electrodes to the lead wires. If
they do not fit, use a dierent set of electrodes and call VQ OrthoCare
to report the situation and receive a replacement set of electrodes.
Save the non-working electrodes for evaluation by VQ OrthoCare’s
Quality Assurance Department; DO NOT THROW THEM AWAY!
3. Gently remove the electrodes from the plastic liner. Place the electrodes
on the sites prescribed by your physician or therapist and press them
firmly onto the skin. Electrodes should be placed at least one inch
apart from each other. Skin irritation or burn could result.

or therapist will show you where to apply the electrodes.
^Always make sure electrodes are placed at least one inch apart
from each other.
To remove the electrodes:
^Grasp the electrode by the edge and gently remove it from the skin.
Return it to the plastic liner.
^Replace the electrodes on the plastic liner in the resealable pouch
provided.
CAUTION: Never remove the electrode by pulling on the wire. This
may damage your electrode.
CAUTION: Be careful when using the Avid IF2 while sleeping.
Wires may tangle and become loose.
Electrode Use and Care
WARNING: This product should be used only under the direct supervision of a
registered healthcare practitioner. Product should be used according to the in-
structions in this manual. Improper use of this or any electrode may result in a
patient burn. Due to the potential for causing skin burns, devices must be limited
to 0.25W per cm2. Electrodes should not be placed on the body so that the Avid
IF’s electrical current flows across the chest. This may cause cardiac arrhythmia.

Avid IF2 Patient Manual | 17
ENGLISH
Replacing Electrodes:
^Electrode life varies due to skin condition, skin preparation, storage,
climate and care. For most patients, electrodes will last for approximately
7-10 applications and removals.
^If your electrodes start to dry out, gently rub a few drops of water into
the gel on the electrode to remoisten.
^After repeated use, reusable electrodes lose their adhesion, deliver
less stimulation and shorten battery life. Replace electrodes that do
not stick uniformly or cause discomfort.
CAUTION: DO NOT attempt to clean the Avid IF2 while in use.
Maintenance, care and cleaning of the Avid IF2 is quick and easy when
these instructions are followed:
Case: Clean the outside of the Avid IF2 case as needed with a damp
cloth and mild soap. Never immerse the Avid IF2 in any liquid. This could
seriously damage the internal electronics. Avoid using cleaning fluids or
solvents to remove stains and dirt. This may damage the casing. DO NOT
use abrasive materials on the LCD viewing area.
Lead wire: Do not bend or crimp the lead wire. Do not use the lead wire if
it is moist or wet – allow to air dry for at least one hour. Always remove the
lead wire by firmly grasping the connector. If possible, tuck in excess length
of the lead wires to avoid interference with normal activity. These wires only
need to be cleaned if they become dirty. Wipe with a damp cloth and dry
thoroughly.
AC Adapter: The Avid IF2 is powered by a non-removable, rechargeable,
internal battery or an AC Adapter. When the AC Adapter is plugged in, it will
charge the internal battery and supply power for operating the device. Use
