6.2 Cleaning

6.3 Storage

7. Troubleshooting
7.1 Device Not Connecting to App
- Ensure Bluetooth is enabled on your smartphone.
- Make sure the Smart Finder is activated and within Bluetooth range of your phone.
- Check if the "Find Tag" app has the necessary Bluetooth and location permissions enabled in your phone's settings.
- Try restarting both your phone and the Smart Finder device.
- If the issue persists, try unpairing and re-pairing the device through the app.
7.2 Tracker Not Found Over Long Distances
The Lenovo Smart Finder AK-28B primarily uses Bluetooth for real-time tracking. Its range is limited by Bluetooth technology (typically up to 10-30 meters indoors, more outdoors). For items beyond this range, the app will display the last known location where the device was connected to your phone. It does not have independent long-range GPS capabilities that would allow real-time tracking over many kilometers without being near your phone or another device in its network. It does not require a SIM card.
7.3 App Asking for Login Credentials or Showing Incorrect Credentials
- Ensure you are using the correct login details for the "Find Tag" app.
- If you have forgotten your password, use the app's password recovery option.
- If the issue persists, try reinstalling the app or resetting the device (if a reset option is available and documented in the full PDF manual).
8. User Tips
- Attach to Valuables: The compact size and keyring attachment make it ideal for keys, wallets, bags, and even pet collars.
- Monitor Battery Life: Regularly check the battery status in the "Find Tag" app to ensure continuous tracking.
- Utilize Bidirectional Search: Remember you can use the tracker to find your phone, not just the other way around.
- Review Historical Data: Use the historical trajectory feature to understand movement patterns of tracked items or pets.
- Share Access: For family items or pets, utilize the "Multiple people view" feature to allow several family members to track the device.
