# Installation and Testing Guide

## Motion-Sensing Trailer Tracker: Installation Guide

### Ideal Placement Guidelines

1. **Avoid Metal Enclosures**
   * Never fully enclose in metal
   * Ensure signal can reach device
2. **Suitable Placement Options**
   * Inside plastic enclosures
   * Under trailer chassis
   * Areas with access to open air
   * More open air exposure = better signal
   * Test placement before final installation
   * Avoid signal-blocking materials

### LED Indicator Guide

* Blue LED: Cellular connection status
* Green LED: GPS connection status
* Both lights off: Successful operation

### Testing Device Location

1. **Initial Test**
   * Locate "Test" button near LED lights
   * Hold until Green and Blue LEDs flash
2. **Watch LED Sequence**
   * Green GPS LED blinks first
   * Blue cellular LED activates next
   * Green LED slows and turns off
   * Both lights off indicates success
3. **Verify Connection**
   * Check account for location update
   * Confirm successful location report
   * Monitor signal strength

{% hint style="warning" %}
When the tracker is unable to detect sufficient satellite signals for a GPS location fix, it will automatically default to reporting the location of the nearest cell tower. If you notice frequent instances of these cell tower backup locations in your tracking reports, consider repositioning the tracker to improve satellite signal reception.
{% endhint %}
