5. Maintenance
5.1 Battery Management
- Regularly charge the device to maintain optimal performance.
- Avoid completely draining the battery frequently, as this can reduce its overall lifespan.
- If storing the device for an extended period, charge it to approximately 50-70% and recharge every few months to prevent deep discharge.
5.2 Waterproofing
The device is IP67 waterproof, meaning it is protected from dust and can withstand immersion in water up to 1 meter for 30 minutes. Ensure all covers and seals are properly closed to maintain this protection. Avoid exposing the device to high-pressure water jets or prolonged immersion beyond its rating.
5.3 Storage
Store the device in a cool, dry place away from direct sunlight and extreme temperatures. The recommended storage temperature range is -40°C to +85°C. The operating temperature range is -20°C to +55°C.
6. Troubleshooting
- Device not powering on: Ensure the battery is charged. Connect to a power source and try again.
- No GPS signal or inaccurate location: Ensure the device has a clear view of the sky. Avoid placing it under heavy metal obstructions. Verify the SIM card is active and has data.
- No network connection (2G): Check if the SIM card is correctly inserted and active. Confirm that 2G network coverage is available in the area.
- Battery draining quickly: This may occur with very frequent tracking updates. Adjust tracking frequency settings in the app if available. Ensure the device is fully charged.
- Cannot access tracking platform/app: Verify your internet connection. Ensure you are using the correct login credentials.
