5. Maintenance
Battery Management
The TK915 is equipped with a 7800 mAh lithium battery, providing up to 80 days of standby time. Actual battery life may vary based on usage frequency, tracking mode (e.g., real-time vs. sleep mode), and signal strength. Charge the device using the provided USB cable when the battery level is low.
Waterproof and Durability
With an IP58 rating, the tracker is protected against dust ingress and immersion in water up to 1 meter for 30 minutes. While it is water-resistant, avoid prolonged submersion or exposure to high-pressure water jets to ensure longevity.
6. Troubleshooting
- No GPS Signal: Ensure the device is outdoors with a clear view of the sky. GPS signals can be obstructed by buildings, tunnels, or dense foliage.
- SIM Card Not Working: Verify that the SIM card's PIN code is deactivated and that it has an active data plan, call, and SMS functions. Reinsert the SIM card firmly.
- Inaccurate Location: In areas with poor GPS signal, the device may rely on LBS (Location Based Service) which uses cellular towers and can be less accurate. Move to an open area for better GPS precision.
- Device Not Responding: Check the battery level. If the battery is charged, try restarting the device if possible, or contact support.
- App Connectivity Issues: Ensure your smartphone has an active internet connection and that the tracker's SIM card has sufficient data.
