Introduction

Congratulations on your purchase and welcome to Philips! To fully benefit from the support that Philips offers, register your product at www.philips.com/

welcome

The Philips health watch empowers you to live a healthier life by continuously tracking activity, calorie burn, sleep habits, heart rate and other key metrics of your cardio condition, and more. The watch can wirelessly connect to a smartphone. An always ON-screen and battery charge of up to 4 days allows you to wear the watch every day and night. You can monitor your metrics and get personalized guidance with the Philips HealthSuite health app.

Intended use

Philips health watch 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. The device is intended for 24/7 use in daily life, both indoor and outdoor, by adults of 18 years and older.

Operating principle

The Philips health watch is a wrist-worn device for 24/7 home use (indoor and outdoor). The device uses a tri-axial accelerometer to measure motion and green Light Emitting Droces (LEDs) and a photodiode to create a photolethysmogram (PPG). The accelerometer output and the PPG signal are analyzed to determine heartbeat, activity type, steps taken, and are used as input for estimation of energy expenditure and other parameters.

IMPORTANT SAFEGUARDS

-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 light, 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.

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.

The clock screen of the watch shows the current time that it synced with your smartphone. To access the main menu, tap on the menu button (Fig. 6). The main menu has 6 different menu options which provide information about your activity, heart rate, sleep, time functions and settings. You can manually add information about your food intake in the dedicated menu section. Tap on the touch ring near the icon of the menu option you want to access (Fig. 7). To return to the main menu, tap on the menu button. From the main menu, return to the clock screen by tapping the menu button again.

The watch does not have a touch screen, only the ring around the display responds to touch. The touch interface does not function when it is wet. Wise the glass dry to enable it again.

Shortcuts menu

Use the shortcuts menu to go straight to your current heart rate, today's burned kilocalones (active and total energy expenditure), steps taken and active minutes. In your clock screen, swipe left or right on the lower part of the touch ring (Fig. 8) to navigate through the shortcuts menu options.

Active energy expenditure

Active energy expenditure shows today's amount of burned calories through sustained physical activity Total energy expenditure

Your total energy expenditure is how many calories you have burned overall today.

This number includes your active energy expenditure as well as the calories your body burns just to function normally.

Steps

Displays today's amount of steps.

Active minutes

This is the time, in minutes, that you've spent being active today. According to the World Health Organization, your body only starts feeling the effects of increased activity after you've been moderately active for 9 minutes, so we start tracking your active minutes from then.

If you have set daily goals via the Philips HealthSuite health app, you can also track your progress here. A progress bar around the outside of the display lets you see how close you are to reaching your goal (Fig. 9). Kilocalone (kcal) is a measurement for energy expenditure as well as for energetic value of nutrients. Calories that are noted in US food packaging are actually kilocalories.

Locking and unlocking the screen

The device automatically returns to the clock screen and locks after 60 seconds of inactivity. To unlock the screen, quickly tap the lower part of the touch ring three times (Fig. 10). To lock a screen and prevent the watch from returning automatically to the clock screen after 60 seconds, quickly tap three times on the lower part of the touch ring at the 6 o clock position (Fig. 11). You will feel a vibration and see a lock appear on the screen. To unlock, tap the lower part of the touch ring three times again.

Heart rate

Select the heart rate in the main menu to see your current heart rate. Swipe left or right to select heart rate, resting heart rate or heart rate recovery. Heart rate, resting heart and heart rate recovery are measured in beats per minute.

Heart rate

Your current heart rate is displayed in beats per minute (bpm)

Resting heart rate

Resting heart rate is the rate that your heart beats at when you are at rest (displayed as rhr). Resting heart rate values can differ from one person to another. However, changes in resting heart rate can be an indication of changes in your fitness level. Active people often have a lower resting heart rate because their heart muscle is in better condition. It will take at least 24 hours of wearing the watch to get a first resting heart rate measurement.

Heart rate recovery

Heart rate recovery (HRR) is the difference in heart rate at peak exercise and the rate as measured after a one minute recovery period. The watch will measure HRR when you are exercising with your heart rate being at least 80% of your maximum heart rate for a minimum of ten minutes. The measurement starts when a change from high intensity activity (running or cycling) to low intensity activity (walking or other) is registered. The watch can detect these activities automatically or you can indicate them yourself (see 'activity recognition'). To obtain an estimate of HRR sit down immediately after stopping your activity and then rest for at least 2 minutes to let your heart rate recover. To make HRR estimates better comparable over time, try to estimate HRR in similar settings with respect to: time of day, type of activity and activity duration.

Important: Do not try to estimate your HRR if you are not very active or unaccustomed to high intensity activity. To reduce the chance of injury during exercise please read the information and follow the general recommendations (see 'GENERAL RECOMMENDATIONS').

Heart rate measurement

Optical heart rate measurement has been shown to provide valid estimates of heart rate for most people under most normal conditions. However, for accurate measurement it is reliant on three key factors:

-Placement of the sensor in direct contact with the skin.

-Transmittance of light through the skin. -Sufficient blood flow through the skin.

Note: When experiencing problems with your heart rate measurements, check if your problem is already mentioned in the troubleshooting chapter, visit www.philips.com/support, call 1-844-531-6861 for assistance or visit the help section in the app.

Heart rate zones

Heart rate zones span the range between your resting heart rate and your maximum heart rate and can help you in identifying the intensity of your exercise. Your heart rate zone is displayed in your heart rate screen. The dot indicates in which heart rate zone you are exercising. If you have set a target heart rate zone in the app, this zone is displayed in black (Fig. 12).

Heart rate zone 1 - Light:

This zone mostly covers regular daily activities such as leisurely strolls, moving around or performing easy tasks within your house or workplace.

-Heart rate zone 2 - Moderate:

Activities that get your heart rate to zone 2 include brisk walking, hiking, leisurely biking and swimming. During such moderate intensity activities, your breathing is often deep and you usually start to sweat after ten minutes.

-Heart rate zone 3 -High:

Training in this zone will help you get fitter. It may also improve your cardiovascular system and help you control your weight.

-Heart rate zone 4 - Anaerobic:

You'll be in this highest zone only for brief periods of time, as anaerobic exercise consists of bursts of high-intensity activity such as sprinting, interval training and heavy weight-lifting.

Sleep

The Philips health watch is designed to also be worn at night to allow automatic sleep tracking. If you are interested in collecting more sleep related information (for example the time to fall asleep), you can manually start the sleep mode when you intend to fall asleep, and stop the sleep mode at the moment of waking up in the morning. To activate sleep mode select Sleep from the menu and press the play icon. The watch will automatically estimate the moment when you actually fall asleep. Press the stop icon when you wake up without the intention to resume sleep. If you wake up in the middle of the night and get out of bed, you do not have to turn off sleep mode, the watch will automatically account for this. In case you have also set an alarm, stopping the alarm will also indicate that you have woken up and stop sleep mode. Data about your sleep will appear in the app within a few hours after you have woken up.

Note: Activation of sleep mode deactivates Bluetooth and sedentary alerts.

Food intake

This option allows you to manually track your calorie intake in kilocalories directly on your watch. Select the food option in the main menu. You have two options:

The first screen shows Food. Enter the Food intake menu by tapping the +’ icon. Tap the arrows at the bottom of the screen to select breakfast, lunch, dinner, drinks or snacks to enter your food intake. Indicate the amount of average by selecting small, normal or large (an average number of calories is assigned). -Swipe to the second page in the food menu which shows the calories you’ve logged today (in kcal). In this screen, tap on the +’ icon to add calories manually. Tap and hold + or - to enter the desired amount of calories. Then select the check icon to confirm the amount of calories. Tip: In the app you can select a type of food and corresponding amount of calories in the food database.

Activity

The Philips health watch can help you gain insight into your activity level by measuring several parameters such as: caloric burn, steps, active minutes, sedentary behavior, heart rate and heart rate zones. For explanation about heart rate zones, see 'heart rate' chapter.

Activity recognition

The Philips health watch can recognize the activities walking, running and cycling and start and stop measurements itself. You can also start and stop measurements manually by selecting the activity option from the main menu. If you want to start your activity manually, you can tap the 'play icon' in the walking, running or cycling screens in the activity menu. You can stop or pause the activity when desired. During your activity you can see information about the activity, the activity duration, your current heart rate and heart rate zone, number of calories burned and steps (in case of walking and running).

Note: You cannot manually stop activities on the device that were started automatically. In User settings you can choose if you see activity screens or current time when an activity is detected.

The device does not respond or the display is dark and the device seems switched off.	The battery is empty.	Put the device in the charging Croatia and connect to a power socket. Wait until the device is fully charged
	There is an internal error.	If the device fails to charge or the device still does not respond, call 1-844-531-6861 for assistance
The glass of the device is broken.	The watch was dropped	Call 1-844-531-6861 for assistance. Do not use the device when the glass is broken.
Heart rate signal is not showing.	Strap is not fastened tight enough around your wrist.	Make sure the watch is worn correctly. Indicate the side you are wearing the watch on in the aop. In the app you can also select if your wearing side is your dominant hand.
	Personal settings are incorrect in the app.	Update and correct your personal settings in the app.
	Watch or skin is not clean.	Clean the device and your skin under the device.
In doubt about accuracy / My device is not measuring correctly.	Direct contact with the skin can be lost if the watch is worn too loosely or when the strap is positioned over the wrist bone or when there is a lot of hand/wrist movement.	Make sure to position the watch correctly and provide a snug but comfortable fit. If this does not fix the issue, try re-positioning the watch at bit higher up on the arm or on the other arm (if you place the watch on the other arm, do not forget to change the watch placement setting in the app).
	Blood flow in the skin can be impacted by increased pressure on the small blood vessels in the skin (e.g. when the watch strap is too tight).	Try loosening the strap a notch to relieve some pressure, but make sure the watch still retains a snug fit.
Blood flow in the skin can be temporarily reduced during warm-up exercises as more blood is directed to the muscles.	Disregard inaccurate measures during warm-up exercises and provide some time for the blood flow to the skin to adjust to the exercising conditions.
Blood flow in the skin can be temporarily reduced when going outside when it is very cold as more blood is directed to the body's core.	Try wearing long-sleeved clothing to cover the watch and starting the measurement inside. Disregard inaccurate measurements during the first couple of minutes and provide some time for the blood flow to the skin to adjust to the exercising conditions.
Transmittance of light through the skin can be influenced by stark contrast in pigmentation of the skin (e.g. due to a pattern in a tattoo). This could result in inaccurate optical heart rate measurement	Try re-positioning the watch at bit higher up on the wrist or on the other wrist (if you place the watch on the other arm, do not forget to change the watch placement setting in the app).
The strap of the watch is too small or too large for my wrist	Change the strap of the watch with the extra strap supplied (See 'Changing the strap').

Electromagnetic environment – guidance

Portable and mobile RI communications equipment should be used no closer to any part of the device, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter Recommended separation distance d = 1.17 vP

d - 1.17 vP 80 MHz to 800 MHz

d = 2.33 V P 800 MHz to 2.5 GHz

Where P is the maximum output power rating of the transmitter in walls (W) according to the transmitter manufacturer and d is the recommended

separation distance in meters (m) Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, should be less than the compliance level in each frequency range. Interference may occur in the vicinity of equipment marked with the following symbol: (ω)

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relotating the device. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended separation distances between portable and mobile RF communications equipment and the Medical device

The device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the device can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the device as recommended below, according to the maximum output power of the communications equipment.
