### Installation & Setup

#### GV57 Boat GPS Tracker & Bilge Alarm Installation Guide

Ensure your vessel is protected and monitored in real-time with this basic installation guide. This manual covers the core hardware wiring and initial software setup for the GV57 Marine Safety Bundle.

#### 1. Pre-Installation Checklist

Before beginning the installation, make sure you have the following ready:

- **Tools Needed:** Wire strippers, electrical tape or marine-grade heat shrink tubing, zip ties, and a voltmeter.
- **Power Compatibility:** Verify your boat uses a standard 12V or 24V DC electrical system (the device supports an 8V to 32V DC range).
- **Safety First:** Disconnect your boat's main battery terminal before handling any electrical wiring.

#### 2. Wiring Configuration Guide

The GV57 hardwired harness features color-coded wires that connect directly to your vessel's electrical and monitoring components. Follow these core connections carefully:

- **Red (VCC)** Constant Positive (+) Battery Terminal; Supplies continuous power to the tracker.
- **Black (GND)**Negative (-) Battery Terminal / Ground; Completes the electrical circuit.
- **White (ACC)**Ignition Switch / Keyed Power Source; Detects engine status (on/off tracking behavior).

#### Connecting the Bilge Monitor & Alarm Components:

- **Float Switch Integration:** Connect the designated input wires from the tracker harness to your bilge pump's submersible float switch. This allows the system to monitor water level shifts and trigger high-water alerts.
- **Audible Indicator:** Route the secondary output to the included 12V dashboard buzzer alarm. This ensures you receive immediate, audible on-board feedback if the bilge level rises unexpectedly.

#### 3. Device Placement & Mounting

To ensure peak performance and reliable network communication, adhere to these placement rules:

- **Orient the Face Upward:** Mount the tracker securely with the front face (LED side) pointing skyward for optimal satellite visibility.
- **LED Status Verification:** Check the integrated face lights once power is restored: **- Green LED:** Flashing indicates an active 4G LTE cellular network connection. **- Red LED:** Solid indicates a verified GPS signal lock.
- **Avoid Metal Shielding:** Secure the IP67 waterproof housing using zip ties underneath the fiberglass console or dashboard. Avoid placing the device directly beneath massive metal brackets, which can block cellular and GPS reception.

#### 4. Software Activation & Default Settings

Once the hardware is securely mounted and drawing power, finalize your system setup:

- **Account Configuration:** Log into your tracking mobile application or web portal to register the unique IMEI number found on your device label.
- **Default Tracking Behavior:** Out of the box, the GV57 is pre-configured to optimize data efficiency and power conservation: **- When Moving:** Automatically transmits location updates every **5 seconds**.  **- When Stopped:** Shifts into a power-saving deep sleep mode and transmits updates every **3 hours**.
- **Alert Customization:** Set up automated text or email notifications within your app settings for critical event triggers, including low battery warnings, power disconnects, high bilge water levels, and geofence boundary crossings.
