Chapter 1: Pain Relief with Quell
Introduction
Quell Wearable Pain Relief Technology™ 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 on the device or by the
"Quell Relief" smartphone app.
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 or using the app on
your smartphone. Regular therapy sessions are 60 minutes. After your first session,
therapy will automatically restart every other hour. Pain relief may begin in as little
as fifteen minutes after 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 from your device or smartphone.
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. Chapter 9 provides information about the optional smartphone app.
APPENDIX C gives answers to frequently asked questions.
If you have any questions about how to use Quell, please call Quell Customer Care at
1-800-204-6577 or, if calling from outside the US, please call [phone].

Chapter 3: Device Basics
Checking Battery
Your Quell will arrive fully charged. To check battery
level, hold the device in your hand and briefly click
the button. The indicator lights will flash white if
the battery has sufficient charge. The number of
illuminated white lights corresponds to the level
of battery charge. Five white lights indicate a fully
charged battery. If orange indicator light flashes,
the battery needs to be recharged (see below for
charging instructions).
Charging Battery
A fully charged battery can provide up to 50 hours
oftherapy for most users.
To charge the battery:
Plug the USB cable into the micro-USB port on
the bottom 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 USB
connector on many computers is not powerful enough to charge Quell. 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. 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.

every 2weeks thereafter. You should reseal the package if it contains an electrode.
Improper storage of the electrode will reduce its life.
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 back of 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. 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 approximately 2 weeks from this date.

Chapter 5: Pain Relief Therapy
During a therapy session, the device will
comfortably stimulate the nerves in your leg to
provide pain relief. Regular therapy sessions last
60 minutes, and a new session will automatically
restart every other hour. If you prefer to not have
automatic restart turned on, consult APPENDIX E
to learn how to turn it off.
To optimize pain relief, you should feel a strong
but comfortable sensation during therapy. The
intensity that you will require is estimated based
on your device calibration. However, because of
differences among people, this estimated intensity
may be too low and feel weak, or too high and
feel uncomfortable. In either case, you should
adjust the intensity as described on page 12. The
greatest pain relief will be obtained when you
set the intensity to the highest level that is also
comfortable. The device will remember changes
made to the intensity after the first two minutes
of therapy and you should not need to adjust
often. Please follow the steps on the following
pages for a therapy session.
Preparing for Therapy Session
Before starting a therapy session make sure you
have an electrode attached to the device. You
should also check the battery to ensure it has an
adequate charge. Place the device on your leg as
described in Chapter 3.
Starting Therapy Session
To start a therapy session, tap the start button on
the Dashboard screen in the app. Or, briefly click
the button on the device. One indicator light will
blink white for the duration of the therapy session.
Chapter 5
Pain Relief Therapy
What Therapy Feels Like
The intensity will gradually increase during the
first two minutes to an intensity that is strong but
comfortable. This strong but comfortable intensity
is based on results of the calibration process. You
may feel a strong sensation at first but it will
typically fade to a comfortable level after a couple
of minutes. If the sensation is uncomfortable
or painful, you should decrease the intensity as
described in the next section. Therapy will continue
for 60 minutes in Regular dose (see page 18 for
personalization options).
Once you have placed the device on your leg,
you may cover the device with your clothing. You
should be careful not to dislodge the device and
electrode when covering with clothing. You may
go about your normal activities during a therapy
session. Do not shower, bathe or swim with the
device on your leg.

Chapter 5: Pain Relief Therapy

You may adjust intensity as needed at any
time during a therapy session using the
button on the device or the smartphone app.
Optimal pain relief will be obtained at the highest
intensity that is also comfortable.
To learn how to control your Quell device with your
smartphone app, please review Chapter 9.
Ending Therapy Session
Regular therapy sessions will run automatically
60 minutes on, then 60 minutes off, unless you
manually turn off therapy during a session or
recalibrate.
To manually stop therapy during a session, click
the button four times in sequence. You should
not remove the device while it is stimulating, so
make sure that the indicator light is not blinking
white before removing the device and electrode
from your leg. Otherwise you may experience an
uncomfortable sensation when you remove the
device.
After completing a therapy session, you may
either leave the device on your leg or remove
it. If you remove the device, be careful to not
damage the electrode and remember to reapply
the liner (see page 15 for instructions on
removing electrode).
Adjusting Intensity During
Therapy Session
Frequent adjustments should not be necessary;
however, if the sensation feels uncomfortable or
is not strong enough, you may make adjustments.
The easiest way to adjust therapy intensity or
to stop therapy is to tap the buttons on the
Dashboard screen in the smartphone app. For
manual adjustments, please follow the directions
below.
Decrease Intensity: Click the button. Each click
decreases intensity. Lights will flash and then go
down to indicate intensity has decreased.

Chapter 7: Electrodes
The electrodes are designed to operate
consistently for up to 2 weeks. With repeated use,
the electrode gel may peel and/or dry out thereby
losing some of its adhesion, but the electrode is
still usable.
Electrode Removal
You should be careful to not damage the electrode
when you remove it from your upper calf area.
Slowly peel the electrode from your skin, while
making sure that each of the gel pads does not
separate from the electrode. Avoid touching the
gel with your fingers as that can damage the
gel and decrease the life of the electrode. After
removal of the electrode, you should cover it with
the liner.
If you have difficulty removing the electrode, refer
to Chapter 8 for tips on skin care to ease electrode
removal.
Electrode Storage
Electrodes should always be stored with the
liner covering the gel pads. Place the liner with
graphic side up so the paper does not stick to the
gel. Electrodes should be stored in a sealed bag
at room temperature out of direct sunlight. You
may also snap the electrode into the device for
convenient storage.
Electrode Replacement
The electrode should be replaced prior to two
weeks if stimulation becomes painful despite
positioning the device so that the entire electrode
is making smooth contact with the skin. You can
order electrodes at www.quellrelief.com/replace
or from the location where you purchased your
device.
Chapter 7
Electrodes
Helpful Tips
• The entire electrode should contact the
skin.
• To get the most use of your electrode,
put the liner back on the gel pads when
electrode is not on skin.
• Air-out skin or switch legs during the
day or after overnight use. After 4
hours of wear, device will pulse on and
off for 1 minute as a reminder.
• Change the electrode every 2 weeks.
• Do not use while showering or bathing.

Chapter 8: Skin Care
Quell works by electrically stimulating your sensory nerves through your skin. Some
people have dry or sensitive skin, and it is important to regularly monitor your skin
where it contacts the electrode to ensure that skin irritation does not occur. If your
skin becomes irritated, using the device may be uncomfortable. There are some simple
things you can do to take care of your skin while using Quell.
Never use the device on open wounds or rashes or over swollen, red, infected, or
inflamed skin.
Chapter 8
Skin Care
Prevent Skin Irritation
Air-out Skin
Air-out skin after 4-5 hours of wear during the day
or after overnight use. Many users simply switch
the device to the other leg every 4-5 hours.
If you have sensitive skin, you may also consider
the following:
Start Slow
Limit the time the device is on your skin to 3-4
hours per day in the first week. If you do not
experience irritation you may increase use while
closely monitoring your skin.
Use Skin Protectant
Apply a skin protectant before placing the device
on your leg. Skin protectants are available as
wipes, swabs, or sprays. They are safe and may
reduce the likelihood of irritation. They also
increase adhesion of the electrode to your skin.
Protectants that work well include:
• 3M Cavilon™ No Sting Barrier Film
• Smith & Nephew SKIN-PREP®
• Smith & Nephew No-Sting SKIN-PREP®
• Coloplast Prep™ Protective Skin Barrier
These products are available online or at selected
retailers.
Check for Skin Irritation
Check for signs of irritation, including:
• Skin itches while device is on
the skin or after removal
• Skin is red where it contacted electrode
• Raised or reddened hair follicles
If skin irritation develops then you should not
place the device over the irritated area until it
completely heals. You may apply a topical steroid
cream to help accelerate healing and reduce
irritation. You may also place the device on the
other leg or use different locations as shown in
APPENDIX D.
If you experience skin irritation, then you should
limit device use to 3-4 hours per day for a week to
make sure that further irritation does not occur.
