Setup Guide
1. SIM Card Requirements and Installation
The LEMFO Q50 Smart Watch requires a Micro SIM card (not included) with 2G network support. It is crucial that the SIM card has GPRS "E" service and call ID function enabled. Prepaid plans with data are generally recommended for compatibility.
- Ensure the watch is completely powered off before proceeding.
- Locate the SIM card slot, which may be on the side or under a small cover secured by screws. Use the provided screwdriver to open the cover if necessary.
- Carefully insert the Micro SIM card into the slot, ensuring the correct orientation as indicated by a diagram near the slot.
- Securely close the SIM card cover.
- Power on the watch. The watch should display network signal bars once connected.
2. App Download and Registration (SeTracker)
To manage the watch's features and track its location, download the "SeTracker" application on your smartphone. The app is compatible with Android (OS 3.0 or above) and iOS (iOS 6.0 or above) devices.
- Scan the QR code provided in the watch's packaging or search for "SeTracker" in your device's respective app store (Google Play Store for Android, Apple App Store for iOS).
- Install and open the application.
- Register a new account using your email address or phone number. Follow the on-screen prompts to complete the registration process.
- Log in to your newly created account.
3. Binding the Watch to the App
After logging into the SeTracker app, you need to bind the watch to your account.
- In the SeTracker app, select the option to add a new device (often represented by a "+" icon or "Add Device").
- Scan the QR code located on the back of the watch or enter the device's registration code manually. This code is unique to your watch.
- Enter the watch's IMEI number (found on the watch or its packaging) if prompted.
- Assign a nickname for the watch (e.g., "Child's Watch") and specify the relationship (e.g., "Mom," "Dad").
- Confirm the binding. The watch should now be connected to your app, and you can begin configuring its features.
Operating Instructions
1. Basic Functions
Power On/Off:
Press and hold the Power button (typically the middle button on the side) for a few seconds to power on or off the watch.
Making Calls:
Children can make calls to pre-set numbers. Press and hold the "SOS" button for 3 seconds to dial the first reserved emergency number. Press and hold the "2" button for 3 seconds to dial the second reserved number. Other contacts saved in the app can also be dialed via the watch's interface.
Receiving Calls:
The watch will ring when an incoming call is received. Press the Answer button (usually the top button) to accept the call.
2. App-Controlled Features
GPS/LBS Location Tracking:
View the real-time location of the watch on the map within the SeTracker app. The watch uses a combination of GPS (Global Positioning System) and LBS (Location Based Service) for positioning, providing more accurate results outdoors with GPS.
SOS Emergency Call:
In an emergency, the child can press and hold the SOS button on the watch. The watch will automatically dial pre-set emergency contacts in a loop until one answers, sending an alert to the app.
Electronic Fence (Geo-fence):
Set up safe zones (e.g., home, school) on the map in the SeTracker app. You will receive an alert on your phone if the watch enters or exits these designated areas, enhancing safety monitoring.
Remote Monitor:
Through the app, you can initiate a silent call to the watch. This allows you to listen to the sounds in the watch's surroundings without disturbing the child, providing an additional layer of security.
Voice Chat:
Send and receive short voice messages between the watch and the SeTracker app, functioning similarly to a walkie-talkie. This is a convenient way to communicate quickly.
Pedometer:
The watch can track the child's steps throughout the day. This activity data can be viewed and monitored within the SeTracker app.
Maintenance
- Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dust and smudges. Avoid using harsh chemicals, solvents, or abrasive materials, as these can damage the watch's finish or internal components.
- Charging: Always use the provided USB charging cable. Ensure the charging contacts on both the watch and the cable are clean and dry before connecting. Do not overcharge the battery; disconnect once fully charged.
- Water Resistance: The LEMFO Q50 Smart Watch is not waterproof. Avoid exposing it to water, rain, splashes, or excessive humidity. Damage due to water exposure is not covered under warranty.
- Storage: When not in use for extended periods, store the watch in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch cannot power on. | Low battery; SIM card not inserted correctly. | Charge the watch for at least 30 minutes. Re-insert the SIM card correctly, ensuring it clicks into place. |
| No network signal. | SIM card not active; poor network coverage; GPRS "E" service not enabled. | Contact your SIM card provider to ensure the card is active and has the necessary services. Move to an area with better network signal. |
| GPS location is inaccurate. | Poor GPS signal (indoors/dense areas); reliance on LBS. | Move to an open outdoor area for better GPS reception. LBS provides approximate location based on cell towers. |
| Cannot bind watch to app. | Incorrect registration code/IMEI; watch not connected to network. | Verify the registration code/IMEI. Ensure the watch has a stable network connection (check signal bars on watch). |
| Cannot make/receive calls. | SIM card not active; call ID function not enabled; numbers not saved correctly in app. | Confirm SIM card is active and has call ID. Ensure contact numbers are correctly saved in the SeTracker app's phonebook. |
