|---|---|---|
| Device not powering on | Loose power connection, no power from vehicle, faulty wiring. | Check power wires (red and black) for secure connection. Verify vehicle's power supply. Ensure correct voltage (12-24V). |
| No GPS signal / Inaccurate location | Device in a shielded location, poor satellite reception, GPS antenna obstruction. | Relocate the device to an area with a clearer view of the sky. Avoid placing it under metal objects or inside enclosed compartments. Allow time for initial GPS fix. |
| No GSM signal / Offline in app | SIM card not inserted correctly, no data plan, incorrect APN settings, poor network coverage. | Ensure SIM card is properly inserted and activated with a data plan. Check APN settings (refer to SIM card provider). Verify network coverage in the area. Restart the device. |
| Remote engine cut-off not working | Incorrect relay wiring, vehicle ignition on, safety protocols preventing cut-off. | Review relay wiring diagram carefully. Ensure the vehicle's ignition is off before attempting cut-off. Some systems prevent cut-off at high speeds for safety. |
| Alarms not triggering | Alarm settings not configured, app notifications disabled, device offline. | Check alarm settings in the BAANOOL IOT app. Ensure app notifications are enabled on your smartphone. Verify the device is online and has a stable GSM signal. |
