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). Kilocalorie (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 food 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: calorie 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. Sedentary behavior To counter the negative effect of prolonged periods of sitting, the sedentary behavior feature will remind you to move with a short vibrating alert. You can change the time interval when the sedentary alert will vibrate in the Philips HealthSuite health app. Alarm, stopwatch and timer Tap on the Clock icon in the menu. Swipe left or right to select the alarm, stopwatch or timer. -- Alarm: you can set the hours of the alarm time by tapping the + and - icons. Tap the check icon to confirm. Then set the minutes by tapping the + or - icons. Tap the check icon again to confirm and set the alarm. When the alarm goes off, the device vibrates until you stop the alarm by tapping the stop icon.
