Alerts and Notifications

The ST-903 supports various alerts to keep you informed:

Working Modes

The ST-903 offers different working modes to optimize battery life and tracking behavior:

• WORK Mode: The tracker continuously operates and sends data based on set time intervals. The device remains online in the application.
• MOVE Mode: The tracker only operates when it detects movement. It appears online in the app when moving but goes offline (sleeps, GPS off, GSM low power) when stationary. SMS commands, vibrations, or calls can wake the tracker for 5 minutes. This is the factory default mode.
• STANDBY Mode: Similar to MOVE mode, but the tracker is primarily in a low-power state. SMS or calls can wake it for 5 minutes. This mode offers extended standby time.

Refer to the SinoTrackPro application or SMS command documentation for details on how to switch between these modes.
