3. Product Installation & Usage Guide

Steps for Setup:

• Insert SIM Card

Install a GPRS-enabled Nano SIM card into the slot.

• Power On

The device auto-powers on upon SIM insertion.

Indicator lights activate; a flashing blue light confirms normal operation.

• Connect to OBD Port

Remove the terminal and plug it firmly into the vehicle’s OBD-II port (see installation diagram).

• Pair via Mobile App

Launch the companion app, enter the device’s SN code, and log in (default password: 123456).

Indicator Light Status (Visible on the device body)

Note: All indicator lights will turn off after 5 minutes of operation, regardless of signal status.

Installation Diagram Notes:

The OBD-II port is typically located under the dashboard near the driver’s left knee area (specific panel shapes may vary by vehicle model).

Functionality of the G-Sensor (Gravity Sensor):

1, Vibration Alarm

Detects abnormal vehicle vibrations (e.g., collisions, unauthorized movement) and triggers real-time alerts.

2, Driving Behavior Analysis

Identifies sudden braking, rapid acceleration, and other actions by analyzing acceleration changes, enhancing safety monitoring.

3, Auto Sleep/Wake Mode

Enters power-saving mode when the vehicle is stationary and reactivates upon movement (requires integration with other sensors).

4, Tilt Detection

Sends alerts if the vehicle tilts or undergoes abnormal angle changes (e.g., accidents or towing scenarios).

Typical Applications:

• Anti-theft systems (alerts triggered by unauthorized towing)
• Fleet management (logs dangerous driving like sharp turns)
• Automatic crash notification (impact severity analysis)

Note: Sensitivity can be adjusted via the companion app to minimize false alarms.
