Chapter 1: Pain Relief with Quell
Introduction
Quell™Wearable Pain Relief is patented non-invasive nerve stimulation technology
that provides relief from chronic pain. It consists of a device and an electrode that
attaches to the device. The device is worn on your upper calf, a few inches below the
knee, and is controlled by a single button.
Quell provides pain relief by comfortably stimulating the nerves that carry normal,
non-painful sensations to your brain, which decreases the perception of pain.
Pain relief is initiated by simply clicking a button on the device. Each therapy session
is 60 minutes. After your first session, therapy will automatically restart every other
hour. Pain relief usually begins within 15 minutes of the start of a therapy session and
may last up to an hour following the end of a session. You have complete control and
can start or end therapy anytime.
You should review this User Manual carefully. Chapter 2 shows you how to get started.
Chapters 3-5 provide detailed instructions on device use. Chapter 6 describes device
use during sleep. Chapter 7 offers tips for taking care of the electrodes. Chapter 8
provides information on preventing skin irritation, particularly if you have sensitive or
dry skin. APPENDIX C gives answers to frequently asked questions.
If you have any questions about how to use Quell please call Quell Customer Service
at 1-800-204-6577.

5. Calibrate
Perform this step only when using the device for
the first time.
Hold the button until you see the lights running
back and forth.
Every time you feel a slight buzzing sensation, click
the button once. The sensation will pause each

When the sensation starts again, click the
button again. You will typically click the button
3-6 times.
When the lights go off, calibration is complete. See
next step to begin therapy.
6. Start Therapy
Click the button. One indicator light will blink. The
sensation will increase for 2 minutes until optimal
intensity is reached. You should feel a strong but
comfortable sensation under the electrode.
Decrease Intensity: Click the button to reduce
intensity. Repeat if needed.
Increase Intensity: Hold button down. Intensity
increases until you release the button.
Turn off: To stop therapy, click the button four
times in sequence.
Each therapy session lasts for 60 minutes with a
60 minute break between sessions. Sessions will
continue until the device is removed from the leg.

Checking Battery
With the device in your hand, briefly click the button
to check the battery. The indicator lights will flash
white if the battery has sufficient charge. The
number of illuminated white lights correspond to
the level of battery charge. Five white lights indicate
a fully charged battery. If indicator light flashes
orange, the battery needs to be recharged (see
below for charging instructions).
Charging Battery
A fully charged battery can provide up to 40 hours
oftherapy.
To charge the battery:
Plug the USB cable into the micro-USB port on
the side of the device.
Plug the other end of the cable into the AC
Adapter. The cable should not be plugged into a
computer USB port for charging.
The AC Adapter should then be plugged into a
standard electrical outlet. The white indicator lights
on the device will show that the device is charging.
The number of lights shown will increase as the
battery charges. When the battery is fully charged,
all 5 lights will be lit for a short time and then all the
lights will turn off. It will take approximately 3 hours
to charge an empty battery. When the battery is
fully charged, unplug the cable from the device.

If the orange light blinks while device is connected to the outlet, charging has failed.
If the battery is too low to start a therapy session, you can charge the device for
approximately 20 minutes to provide enough battery life for one therapy session. To
confirm, disconnect the USB cable from the device and briefly click the button. If at least
1 white indicator light flashes, battery has enough charge for one therapy session. If the
orange light flashes, reconnect the USB cable and continue charging.
Do not use your device with the USB cable connected.

Attaching Electrode
You will need to attach a new electrode prior to first use of the device and on
average every 2weeks thereafter (can be extended up to 3 days if a new electrode
is not available). You should reseal the pouch if it contains an electrode. To attach an
electrode, snap the electrode into the two connectors as shown below.
Only use Quell electrodes manufactured by NeuroMetrix, Inc.
1. Slide device into band pouch with lights
facing up.
2. Align the snaps on the electrode to the snap
connectors on the device. Insert snaps until they
are securely fastened.
3. Remove the liner covering the electrode prior
to placing the device on your leg. Remember
to keep the liner as it should be re-applied to
protect the electrode when not in use.
4. A white label is affixed to each electrode liner.
The first time you use a new electrode, write
the date on the liner. When placing liner on the
electrode when it is not in use, ensure graphics
on liner are facing up so that the paper side
doesn’t stick to the gel. The electrode should
be replaced 2 weeks from this date (can be
extended up to 3 days if a new electrode is
notavailable).

Device Placement
Place the device on your upper calf about
1-2inches below the knee. You may place on either
leg. Be sure the electrode is only covering healthy
skin that is not irritated and does not have cuts
or other wounds. Position the device so that it
is comfortable, the button is accessible, and you
experience a strong yet comfortable sensation
during therapy. You may position the device
with the button on the inside, outside, or back
of the leg. You should avoid placing one of the
compartments directly over your shinbone.
If the device cannot be placed in the standard
location as shown, refer to APPENDIX D for
alternate site options.
Wrap the band around your leg and attach it
with the Velcro®. The device should fit securely
around your leg and be comfortable to wear.
The electrode should make smooth contact with
the skin. If there is buckling of the electrode,
smooth the electrode and re-secure the band.
It is important that all four electrode pads are
in contact with your skin. If the pads are only
partially on the skin, then the stimulation may
feeluncomfortable.
The band was designed to stretch and fit
most legs. If you can’t get it to fit, contact
Customer Service.
