8. Troubleshooting
If you encounter issues with your TKSTAR TK905B GPS Tracker, please refer to the following common solutions:
- Device not powering on: Ensure the battery is charged. Connect the device to a power source and check if the charging indicator lights up.
- No GPS signal: Move the device to an open area with a clear view of the sky. GPS signals can be obstructed by buildings, tunnels, or dense foliage.
- No GSM signal: Check if the SIM card is correctly inserted and active. Ensure the SIM card has network coverage in the current location.
- Inaccurate positioning: In areas with poor GPS signal, the device may rely on LBS (Location Based Service), which can be less accurate. Move to an area with better GPS reception.
- App/Platform not showing data: Verify that the SIM card has GPRS data enabled and sufficient balance. Check your internet connection on your phone or computer. Ensure you are logged in with the correct device ID.
- Battery draining quickly: Check the tracking interval settings. More frequent updates consume more battery. Ensure the device is entering sleep mode when stationary.
For more detailed troubleshooting or persistent issues, please refer to the paper instruction manual included with your product or contact the seller for assistance.
