Troubleshooting
Common Issues and Solutions
- No Signal/Offline: Ensure the device is securely plugged into the OBD-II port. Verify your subscription status is active. Check for adequate 4G/2G network coverage in the device's current location.
- Inaccurate Positioning: GPS accuracy can be affected by environmental factors such as tall buildings, dense foliage, or underground parking. Move the vehicle to an open area for better GPS signal reception. Note that LBS positioning is inherently less accurate than GPS.
- Device Not Powering On: Confirm the vehicle's OBD-II port is supplying power. The internal battery provides limited backup power; if the vehicle's power is off for an extended period, the device may shut down.
- Alarms Not Triggering: Check alarm settings within the mobile application or web platform to ensure they are correctly configured and enabled for the desired events.
- Historical Data Missing: Ensure the device has been consistently powered and connected to the network during the period in question. Historical data is stored for up to 180 days.
If issues persist after attempting these solutions, please refer to the support section or contact customer service for further assistance.
