The Sentar V80 Watch is a smart wearable device designed primarily for children, offering a range of communication, safety, and health monitoring features. It integrates GPS, LBS, AGPS, and Wi-Fi for real-time location tracking, ensuring parents can always know their child's whereabouts. The watch supports two-way phone calls, allowing children to communicate with pre-approved contacts and parents to reach their child. An intercom feature facilitates short voice messages between the watch and the companion mobile application.

For safety, the Sentar V80 includes an "SOS emergency" alarm. In an emergency, the child can long-press the SOS button to initiate a call to up to three pre-set SOS family numbers in a circular fashion for two rounds. If no one answers, an SMS alert can be sent to the monitor number. The watch also features a geo-fence function, enabling parents to define safe areas and receive alerts if the child exits these boundaries. An "SOS remind" SMS alert can be configured to notify the monitor number if an SOS call goes unanswered. Additionally, a "take off watch" alert can be enabled to inform parents if the watch is removed, with an SMS alert option. This feature requires the watch to be worn for at least 3 minutes to function correctly.

Health monitoring is a key aspect of the Sentar V80. Equipped with a 3D sensor, it can count steps, calculate the corresponding distance (journey), and estimate calorie consumption (amount of exercise). Parents can enable this "HEALTH-Walk" function via the app and adjust the child's steps and weight for improved accuracy. The watch also monitors "turnover of sleep," providing insights into the child's sleep quality based on turning frequency. Both health features can be switched on and configured through the companion application.

Communication features extend beyond calls and intercom. The watch supports a "Make friend" function, allowing children to add other Sentar V80 users as friends by touching their watches. Only one friend can be added at a time, and friends can be changed by deleting the current friend via the app. The "Talk" feature enables chat with the app, where users can hold a button to record a voice message and release it to send.

The Sentar V80 is managed through a dedicated mobile application called "SeTracker," available for both Android and iOS. After installing the app, users need to register an account, inputting the watch ID, account name, device nickname, parent phone number, and a login password. The watch ID can be found by navigating to "APP download" on the watch and magnifying the QR code. The app serves as the central hub for configuring all watch settings and monitoring its functions.

Usage features include a main interface displaying essential information such as GSM signal, beep mode, positioning icon, data, light sensor, battery level, time, and date. The watch screen can be slid to switch between different displays. A phone book allows up to 15 numbers to be set in the app, which can then be dialed directly from the watch. Incoming calls can be answered by touching the phone button on the screen, and volume can be adjusted. Calls can be hung up with a short press of the power/SOS button.

Maintenance features include remote shutdown via the app, which requires a SIM card to be installed in the watch. The watch can also be turned on or off by long-pressing the power/SOS button. The "Restore the default work mode" option sets the GPS to be open 24 hours with a 10-minute upload interval. The app also allows for editing personal data, adding/deleting devices (supporting more than one watch per account), and changing the password. It's crucial to ensure the watch ID in the device list matches the QR code ID for proper connection.

The watch also offers several alert settings configurable through the app. These include low-voltage reminders (sending an alert message to the monitor number when the battery drops below 20%), SOS reminders, and take-off watch alerts. A "Do not disturb" function shields all incoming calls during specified times, which is useful for school hours. Parents can also send "rewards" in the form of love hearts to the watch to interact with and encourage their children. Up to three alarm clocks can be preset, and a "Watch" command can be sent from the app to make the watch ring for one minute, which can be stopped by pressing any key on the watch.

Troubleshooting guidance is provided for common issues, such as the watch failing to connect to the server. Users are advised to confirm proper SIM card installation, ensure it's a GSM SIM (CDMA is not supported), verify 2G data traffic activation and sufficient credit, and check watch parameters (ID, IP, port) by sending a specific SMS command to the watch. This comprehensive set of features makes the Sentar V80 a robust and reliable device for child safety and communication.
