Intended use
Philips health band measures, tracks, and analyzes
movement and physiological parameters. These
metrics are intended as input for behavioral
change programs for managing lifestyle of
individuals with risk of or affected by weight and
activity related chronic disease.
Investigation of these parameters is used in the
assessment of the physiological state of a person
and their daily physical activity level. For people at
risk of these lifestyle related chronic diseases or
patients with a pre-existing condition, the
continuous monitoring of these parameters can
give insight in changes of heart rate and daily
physical activity.
The non-medical purpose is measurement of:
steps, resting respiration rate and sleep patterns,
and providing: automatic activity recognition
(cycling, running, walking), a heart rate zone
indication and sedentary behavior alerting, for
wellness purposes.
The device is intended for 24/7 use in daily life,
both indoor and outdoor, by adults of 18 years and
older.
The Philips health band is intended to be used by
one adult consumer only.
Operating principle
The Philips health band is a wrist-worn activity
(accelerometer) and heart rate measurement
device that uses the Opticardiogram technology.
The general operating principle of this
Opticardiogram technology is based on LEDs
emitting light through the surface of the skin. Part
of that light is reflected and collected by the photo
sensor.
The blood flow in the arteries is driven by the heart
beating and pumping blood. The blood flow
changes over time. Therefore, the amount of light
reflected varies over time. The sensor in the health
band collects this change in reflection of light.

- It is important to always listen to your body first,
instead of only relying on measurements of the
health band. Too intense exercising may cause
health problems like feeling dizzy or faint,
nausea, temporary chest pain or exhaustion.
- Consult your doctor before you start exercising
in the following situations:
-If you have heart disease, kidney disease
and/or diabetes mellitus type 1 or 2.
-If you are taking medicines for high blood
pressure and/or that influence your
(maximum) heart rate. (In case of doubt,
please check with your doctor).
-If you have a heart condition or if you are in
cardiac rehab.
Ask your doctor about which exercises you can
do and what your target heart rate should be.
Exercising with a too high heart rate could
cause health problems like temporary chest
pain, heart overload or exhaustion.
- Always consult your doctor first before you start
or continue exercising if you experience any of
the following signs or symptoms:
-If you feel dizzy or nauseated or feel that
you are about to faint.
-If you feel unusually tired or exhausted
during normal activities.
-If you feel pain in your chest, neck, jaw or
arms.
-If you feel your heart beats too hard or too
fast.
-If you are short of breath during rest or mild
exertion, when lying flat or during the night.
-If you have a known heart murmur.
-If you have swollen ankles.
Exercising with any of these symptoms might
increase the risk of heart problems.
- Avoid vigorous to near-maximal activity if you
are not very active or not accustomed to this.
Too intense exercising may increase the risk of
injuries (e.g. falls, sprains) and may cause health
problems like fainting, nausea, temporary chest
pain or exhaustion.
- During pregnancy:
-Always follow your doctor's advice on
weight management, exercise type,
frequency, duration, intensity and rest
intervals.
-The heart rate zone indicator is not
applicable.
-Make sure that you update your weight in
the app on a regular basis. Failure to do so
might result in inaccurate energy
expenditure (calorie burn) estimation.
Heart rate related algorithms and resting
respiration rate are not validated for pregnant
women.
- Keep the device out of reach of infants, children
or pets. Inhalation or swallowing of small parts
can be dangerous.
- Sleep tracking should not be used for diagnosis
or treatment in case of sleep disorders. The
algorithms are not validated for people with
sleep disorders and thus may give inaccurate
results in these cases.
- Only use a double-insulated IEC60950-1 class
II USB adapter or USB port to charge the device
Check if the symbol for double insulation is on
the adapter: .
If you don’t use a double-insulated IEC60950-1
class II USB adapter it could malfunction. This
may cause injury, e.g. electrical shock, or
damage.

reduced physical or mental capabilities, or lack
of understanding and knowledge. They can
only use the device under supervision or after
instruction by a person responsible for their
safety.
- To reduce the risk of skin irritation, follow the
instructions in chapter 'Wearing the health
band'.
- Energy expenditure algorithms are not
validated for people with impaired gait. These
users should not use the total and active
calories burned as shown on the device as a
reference for their actual calories burned.
Caution
- Do not use the device near strong electric or
magnetic fields, for example magnets, radio
transmitters or microwave ovens. This could
cause measurement errors.
- Do not share the device. The Philips health
band is designed for personal use only. The
health band measures several health
parameters, which are updated over time and
are personalized. Switching the health band
between different people could lead to
inaccurate calculations of several health
parameters.

-Wear appropriate clothing and protective
gear
-Always perform proper warm-up and cool-
down procedures
-Slowly progress your activity level; plan 2-3
months to gradually increase exercise
duration and intensity. If you are not very
active, it is a good idea to start with taking
brisk walks on a regular basis.
-Avoid vigorous to near maximal activity if
you are not very active or unaccustomed to
this.
Reactions and side effects
You may experience adverse reactions. This is due
to wearing the device in contact with your skin for
long periods at a time. These reactions may
include:
- Skin reactions due to pressure of the device on
the skin or the device rubbing against the skin.

Wearing the health band
Always wear the Philips health band on the
outside of your wrist (Fig. 4, Fig. 5), in direct
contact with your skin (Fig. 6). Make sure that the
health band is not on your wrist bone (Fig. 7). The
health band is designed to be worn day and night.
Note: You can wear the health band on your left or
right wrist. In the app you can also set which hand
is your dominant hand. Make sure the wearing side
in the settings menu of the HealthSuite health app
is the same as the wearing side on your wrist. If
you wear the health band on your other wrist, also
change the wearing side in the app to ensure
correct health metrics.
Avoiding skin reactions
To reduce the risk of skin reactions follow these
instructions.
- Clean the device and skin underneath the
device regularly and after each sports session.
Take the health band off once in a while to give
your skin some rest.
- Always dry the device when it has become wet.
- Do not wear the strap too tight, to ensure it is
still comfortable to wear.
Wearing the health band comfortably
- Wearing clothes over your health band could
cause the health band to slide across the skin
slightly. This might feel uncomfortable.
- At any point during the day or after exercising
your wrist may be swollen, this is a natural
effect.
- If you feel any discomfort due to the straps,
give your skin some rest by not wearing the
health band for a short period of time or by
wearing the health band on your other wrist.
When you refasten the health band, try
loosening the strap a notch.
Wearing the health band correctly
Wearing the health band correctly will positively
influence the accuracy of the measurements.
Accurate measurements rely on three key factors:
- The sensor should be in direct contact with the
skin. Make sure that the health band is
positioned correctly and not worn too loose
(ensure a snug but comfortable fit). Make sure
the health band and your wrist are clean and
do not have moisture and dirt on them. When
skin contact is lost due to a lot of hand/wrist
movement, you can try re-positioning the
health band at bit higher up on the arm or on
the other arm.
- The health band should be able to transmit
light through the skin. For example, tattoos in
the wrist area might cause inaccurate
measurements, because less light is transmitted
through the skin. Try re-positioning the health
band to a place where you do not have tattoos,
e.g. higher up on your wrist or wear it on your
other wrist.
- There should be sufficient blood flow through
the skin for an accurate measurement.
