contact with your skin for long periods at a time. 
These reactions can include:

 

-

Skin reactions to pressure or friction of the 
device against the skin.

Warning

 

-

Only use a double insulated IEC60950-1 class II 
USB-adapter or USB-port for 

charging

.  

Check if the USB-adapter has the symbol for 
double insulation:  . If you don’t use a double 
insulated IEC60950-1 class II USB-adapter, 
the USB-adapter could malfunction and cause 
injury.

 

-

Consult your doctor prior to starting an exercise 
regime if you have heart 

disease,

 kidney 

disease and/or diabetes mellitus type 1 or 2.

 

-

Do not start or continue exercising before 
consulting your doctor if you experience any of 
the following

 signs or symptoms:

 

-

feeling dizzy, nauseated or about to faint

 

-

feeling unusual fatigue with usual activities,

 

-

feeling pain in your: chest, neck, jaw or arms,

 

-

feeling that your heart is beating too hard  
or fast,

 

-

having shortness of breath during rest/mild 
exertion, when lying flat or during the night,

 

-

having a known heart murmur,

 

-

having swollen ankles.

 

-

Exercising while experiencing any of these 
symptoms might increase the risk of heart 
problems.

 

-

It is important to always listen to your 
body first, instead of only relying upon 
measurements that the watch provides.

 

-

If you are taking 

medicines

 that lower your 

maximum heart rate (e.g. for high blood pressure), 
consult your doctor. Ask your doctor what your 
target heart rate zone should be.

 

-

If you have a 

heart condition

 or you are in 

cardiac rehab, talk to a healthcare professional 
about what exercises you can engage in 
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.

 

-

Do not share the device. The Philips health 
watch is designed 

for personal use only.

  

The watch measures several health parameters, 
which are updated over time and are tailored 
to you. Switching the watch between 
different people would lead to inaccurate 
measurements. 

 

-

Do not modify

 this equipment. This may result 

in hazardous situations. Make sure the device is 
in proper working condition before use.

 

-

Only use the 

charging cradle and detachable 

parts 

authorized by the manufacturer. The use 

of unauthorized parts or accessories may cause 
injury or damage to the device.

 

-

To reduce the risk of skin irritation please follow 
these instructions: 

 

-

Clean

 the device and skin underneath 

the device regularly and after each sports 
session. Take the watch 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. 

 

-

Follow the instructions in chapter  
‘Wearing the health watch’.

 

-

Keep the device 

out of reach of infants, 

children or pets, 

since inhalation or swallowing 

of small parts can be dangerous or even fatal.

 

-

Keep the device away from fire and heat 
sources. The 

internal

 

batteries

 can overheat and 

may explode or leak, causing fire or explosion.

 

-

During 

pregnancy,

 always follow your doctor’s 

advice with regards to weight management, 
exercise type, frequency, duration, intensity 
and rest intervals. Be aware that the heart rate 
zone indicator is not applicable when you are 
pregnant. Make sure to update your weight 
in the app on a regular basis. Failure to do so 
might result in inaccurate energy expenditure 
(calorie burn) estimation.

 

-

Sleep

 algorithms should not be used for 

diagnosis or treatment in case of sleep 
problems. They have not been validated for 
people with sleeping disorders.

Caution

 

-

Do not use the device near 

strong electrical or 

magnetic fields,

 for example magnets, radio 

transmitters, microwave ovens. This could cause 
measurement errors.

 

-

Use this device under the right 

environmental 

conditions

 as indicated in this user manual. 

If not, this could affect the performance and 
lifetime of the device and measurement results.

 

-

If you have any 

problems with this device

,  

such as setting up, malfunction, maintenance, 
visit 

www.philips.com/support 

or call  

1-844-531-6861 for assistance.

 

-

If you have doubts about the 

accuracy of the 

measurements

 by the watch, stop using the 

watch and read the troubleshooting section.  
If you cannot find a solution there, visit

  

www.philips.com/support

 or call  

1-844-531-6861 for assistance. Accurate 
measurement relies on three key factors: 
Placement of the sensor in direct contact with 
the skin, transmittance of light through the skin, 
and sufficient blood flow through the skin.  
There are conditions where accurate optical 
heart rate measurement is not possible. 

GENERAL RECOMMENDATIONS

 

-

Read this user manual carefully and always 
follow the instructions.

 

-

Do not use this watch for any other purpose 
than what it is intended for.

 

-

Make sure the device is in proper working 
condition before use.

 

-

Do not wear the device when showering, 
bathing, swimming or scuba diving, as this may 
damage the device. The device is water resistant 
and is protected against rain and sweat. 

 

-

Exercising at the right intensity is important 
to improve your overall health. The general 
recommendation for physical activity is 
to have at least 150 minutes of moderate 
intensity activity per week. This can made up 
of segments of at least 10 minutes duration. 
Additionally, it is important to note that even if 
you cannot achieve the recommended amount 
of physical activity, being physically active to 
a lesser amount (e.g. 90 minutes per week) is 
better than being inactive.

 

-

To reduce chances of injury during exercise 
follow these recommendations:

 

-

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.

display the battery charge indicator with 100%.

Tip: Charge your device during a meal or any other 
time when you are not active.
