Notes on Work Modes
  • Regular GPS mode
    In this mode, the device always has its network services enabled and will upload location data at a fixed interval, which can be configured via the location service platform or mobile app specified by your dealer.

  • Tracking mode (default)
    In this mode, the device can automatically recognize current location conditions and activity status of the vehicle on which it is installed and intelligently choose a positioning system and an upload interval.

  • Power-saving mode
    The device will wake up at a certain configured interval to upload location data. After each upload is complete, the device will enter deep sleep and will not execute any remote query or set actions.

Alert Functions
  • Tamper Alert
    The light sensor will be blinded once the device is installed securely. Therefore, if the light sensor detects its ambient environment changes from dark to light, the device will upload a tamper alert.

  • Temperature Exception Alert
    The device will upload a temperature exception alert if it detects the ambient temperature to be higher or lower than the preset threshold.

  • Humidity Exception Alert
    The device will upload a humidity exception alert if it detects the ambient humidity to be higher than the preset threshold.
    Note: By default, the device uploads temperature and humidity data every 5 minutes. The upload interval is configurable.

  • Door Open and Close Alert
    The device will upload a door open or close alert if it detects a door open or close action.
    See the following figure for installation:

  1. Check: Install by the above figure. After that, if the 4 battery strength indicators light up, the distance between the magnet and the device is proper and the installation is complete.
  2. After the installation, open or close the door to see if the 4 indicators will light up or go off accordingly. If yes, the device will upload door open or close alerts to the platform.
  • Angle Exception Alert (Only Valid in Tracking mode)
    The device will upload an angle exception alert if it detects the vehicle has tilted or rolled over. The detection duration is about 5 minutes.

  • Collision Alert (Only Valid in Tracking mode)
    The device will upload a collision alert if it detects the vehicle has collided with another object.
