LED Light Overview

Your hardwired tracker (GV-50) has two LED indicator lights that show the device's connection status. These lights help you verify proper installation and diagnose connection issues.

LED Locations: The indicator lights are typically visible on the tracker unit after installation.

What Each Light Means

Green LED (Cellular Connection)

Purpose: Shows your tracker's connection to the Hapn platform through cellular networks.

Light Patterns:

• Slow blinking (once every 3 seconds): Good cellular connection - normal operation
• Rapid blinking (once per second): Actively attempting to connect to cellular network
• Off: No cellular connection or device powered off

Red LED (GPS Connection)

Purpose: Shows whether your tracker can determine its location using GPS satellites.

Light Patterns:

• Blinking red: Searching for GPS satellites
• Solid red: Successfully connected to GPS satellites with good signal
• Off: Device in standby mode, powered off, or GPS signal lost

Normal Operation Patterns

Optimal Performance

What you should see: Red LED solid + Green LED slow blinking

• GPS has satellite lock for accurate positioning
• Cellular connection is strong and data is transmitting
• Tracker is operating normally

Initial Startup/Connection

What you might see: Red LED blinking + Green LED rapid blinking

• Both GPS and cellular are connecting (normal after installation or power cycle)
• Expected duration: 2-10 minutes depending on location and signal strength
• Action: Wait for connections to stabilize

GPS Signal Issues

What you might see: Red LED blinking/off + Green LED slow blinking

• Cellular connection is good but GPS needs better signal
• Common causes: Underground parking, dense urban areas, poor sky view
• Action: Vehicle will reconnect to GPS when moved to open area

Common Light Combinations

Troubleshooting Light Issues

No Lights At All

Possible causes:

• Tracker not properly connected to vehicle's electrical system
• Blown fuse in installation circuit
• Vehicle battery disconnected or dead
• Faulty wiring during installation

Solutions:

1. Check vehicle power: Ensure vehicle battery is charged and connected
2. Verify installation: Confirm all wiring connections are secure
3. Check fuses: Look for blown fuses in the circuit used for installation
4. Test with ignition: Try with vehicle ignition in different positions
5. Contact installer: If professionally installed, contact the installation service

Green LED Rapid Blinking for Extended Time

Possible causes:

• Poor cellular coverage in current location
• Network connectivity issues
• SIM card or cellular module problems

Solutions:

1. Move vehicle: Drive to area with better cellular signal
2. Wait longer: Initial cellular connection can take 10-15 minutes
3. Check coverage: Verify cellular service in your area
4. Restart system: Turn vehicle off for 5 minutes, then restart

Red LED Won't Turn Solid

Possible causes:

• Obstructed GPS signal (underground, covered areas)
• Poor tracker placement blocking GPS antenna
• GPS module issues

Solutions:

1. Move to open area: Drive to location with clear view of sky
2. Wait for acquisition: GPS connection can take 5-10 minutes outdoors
3. Check placement: Ensure tracker isn't blocked by metal dashboard components
4. Test different locations: Try parking in various outdoor locations

Intermittent Light Patterns

Possible causes:

• Loose wiring connections
• Intermittent power supply
• Poor installation

Solutions:

1. Check connections: Verify all wiring is secure and properly connected
2. Inspect installation: Look for loose connections or damaged wires
3. Monitor patterns: Note when lights behave normally vs. abnormally
4. Professional inspection: Have installation checked by qualified technician
