The EW4 Smart Watch is a versatile wearable device designed to track various aspects of your health and fitness, offering a comprehensive user experience through its integration with the Letsfit app. This manual provides detailed instructions for setting up, using, and maintaining the watch, ensuring users can maximize its potential.
The EW4 Smart Watch serves as a personal health and fitness companion, offering a wide range of tracking capabilities. It can track your exercise data across up to 14 different sports modes, allowing you to choose the specific activity you're engaging in. Beyond sports, it records your daily training data, providing a holistic view of your physical activity.
A key feature is its continuous real-time heart rate monitoring, which automatically tracks your heart rate throughout the day. The watch also offers sleep tracking, providing a comprehensive analysis of your sleep duration and quality to help you improve your routine. For more specific health metrics, the EW4 can measure your blood oxygen level and monitor your daily stress level, generating a stress score based on heart rate variability.
Beyond health tracking, the watch includes practical functions such as breath training for relaxation, setting alarms with customizable times and repeat days, and controlling music playing on your smartphone. It also provides notifications for incoming calls and messages (from platforms like Facebook, Twitter, and Instagram), displaying caller ID and message content directly on the watch screen. A sedentary reminder function encourages you to get up and move if you've been sitting for too long. Basic settings and information about the watch are also accessible.
The EW4 Smart Watch is designed for ease of use with a touch screen interface and two physical buttons. The "Up" button wakes the screen, navigates to the function list, returns to the home screen, or pauses/resumes a sport. Holding this button ends a sport mode or powers the watch on/off. The "Down" button takes you to the Training interface, enters sport tracking mode, or flips through exercise data during sports.
The home screen displays the time and date, which is automatically set once paired with your phone. From the home screen, you can swipe down to view notifications, swipe up to access the status bar (for brightness control, do not disturb, settings, and wrist sense), and swipe left/right to switch between function shortcuts like daily activity data, heart rate, stress monitoring, and sleep.
Setting up the watch involves charging it fully before initial use. The wristbands are designed for easy disassembly and assembly using a quick-release lever. For optimal heart rate tracking, it's recommended to wear the watch a finger's width below your wrist bone, lying flat, for all-day wear. During exercise, wearing it slightly higher and snug (but not constricting) can improve signal accuracy.
The watch integrates with the Letsfit app, available on App Store and Google Play. After registering an account and verifying your email, you can pair the watch with your smartphone via the app (not directly through your phone's Bluetooth settings). The app allows for detailed data viewing, historical trends, sleep logging, and further customization of watch settings, including watch faces. You can choose from pre-set watch faces or use a photo from your phone's album.
When tracking sports, you can set training goals such as distance, duration, or calories burned. For outdoor runs, a virtual running competitor can be set to help improve performance. The watch can also utilize your phone's GPS for tracking pace and distance during outdoor sports like running, walking, cycling, and hiking, provided the Letsfit app runs in the background and location services are enabled. During GPS tracking, it's advised to wait for a successful GPS connection in an open area for best results.
Notifications for calls and messages require "Notification alerts" to be enabled in the Letsfit app. The "Do not disturb" function, if enabled either in the app or on the watch, will prevent notifications during that period.
To ensure the longevity and proper functioning of your EW4 Smart Watch, as well as to prevent skin irritation, regular maintenance is crucial.
The EW4 Smart Watch is designed for recreational use and is not a medical device. Consult a physician for any health concerns or if skin irritation persists.
