Setup Guide
Follow these steps to get your Wonlex KT19Pro smartwatch ready for use:
- Charge the Smartwatch: Before first use, fully charge the watch using the provided magnetic USB cable. Connect the magnetic end to the charging points on the back of the watch and the USB end to a power adapter (not included) or computer.
- Insert Nano SIM Card: The watch requires a Nano SIM card with 4G network support. Ensure the SIM card is active and has a data plan. Carefully open the SIM card slot cover (usually on the side of the watch) and insert the Nano SIM card as indicated by the diagram. Close the cover securely to maintain water resistance.
- Download the App: Scan the QR code provided in the watch's user manual or on the watch screen to download the companion app (e.g., Setracker 2) on your smartphone (iOS or Android).
- Register and Bind the Watch:
- Open the app and register a new account.
- Follow the in-app instructions to bind the smartwatch to your account. This usually involves scanning a QR code displayed on the watch screen or entering the watch's unique ID.
- Set up guardian numbers, SOS contacts, and other essential settings within the app.

Operating Instructions
The Wonlex KT19Pro smartwatch features an intuitive touch screen interface. Swipe left/right to navigate between apps and functions.
Key Functions:
- Phone Calls: Tap the 'Phone' icon to dial numbers or select from your contacts. You can set up to 10 contacts via the app.
- Video Calls: Initiate two-way video calls directly from the watch. This feature requires a stable 4G connection.

- SOS Emergency Call: In an emergency, long-press the SOS button (usually on the side of the watch) for more than 3 seconds. The watch will automatically call the pre-set SOS numbers in a loop until one is answered and send alarm messages to these contacts.

- Real-time Location Tracking: The watch uses GPS, WiFi, and LBS for accurate positioning. Parents can view the child's location in real-time through the companion app.

- Class Mode: Set specific times in the app when the watch functions are restricted to prevent distractions during school. Only SOS calls will be active during this period.

- Voice Chat: Send and receive voice messages with pre-approved contacts.
- Camera: Use the built-in 0.3MP camera to take photos. Photos are stored in the watch's gallery.
- Pedometer: Tracks steps taken. Enable the step switch in the app for data synchronization.
- Other Apps: Access various applications like Alarms, Stopwatch, Calculator, Calendar, Music Player, Video Player, Sound Recorder, and games from the watch's app menu.

Maintenance
- Cleaning: Wipe the watch screen and body with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Water Resistance: The watch is IP67 life waterproof, meaning it can withstand splashes, rain, and brief immersion in shallow water. It is not suitable for swimming, bathing, or diving. Ensure the SIM card slot cover is securely closed to maintain water resistance.
- Battery Care: To prolong battery life, avoid extreme temperatures. Charge the watch regularly and do not let the battery completely drain for extended periods.
- Storage: When not in use for a long time, store the watch in a cool, dry place.

Troubleshooting
- Watch not turning on: Ensure the watch is fully charged. Connect it to the magnetic charger and wait a few minutes before attempting to power it on.
- No network signal/calls not working: Check if the Nano SIM card is correctly inserted and active with a 4G data plan. Verify network coverage in your area.
- Inaccurate GPS location: GPS signals can be weak indoors. For more accurate tracking, ensure the watch is outdoors. You can adjust the tracking frequency in the companion app (e.g., Setracker 2) to get more frequent updates.
- Cannot download apps (e.g., Google Play): The watch runs on Android 8.1 but may have a customized OS that does not support direct Google Play Store access. Apps are typically managed through the watch's built-in App Store or pre-installed.
- Screen damage: If the screen is broken, contact customer support for repair options. Screen replacement may be possible depending on the extent of the damage and service availability.
- Watch not connecting to app: Ensure Bluetooth is enabled on your smartphone and the watch is within range. Restart both the watch and the app. Re-bind the watch if necessary.
User Tips
- Voice Monitoring: The watch supports a voice monitoring feature (sometimes referred to as 'callback' or 'eavesdropping' in some regions). Once a phone number is confirmed in the app, the watch can automatically call that number without the user knowing, allowing guardians to listen to the watch's surroundings.
- Regional Compatibility: Ensure the watch's 4G network bands are compatible with your local network provider. The product is suitable for various Asian and European countries, but specific regional homologation might be required.
- App Management: Utilize the companion app to its full potential. It allows you to manage contacts, set safe zones, configure class mode, check location history, and receive alerts.
