LED Light Locations

Your OBD GPS tracker has two LED indicator lights located on the end of the device that faces outward when plugged into your vehicle's OBD port:

• Blue LED: GPS connection status
• Green LED: Cellular network connection status

What Each Light Means

Blue LED (GPS Connection)

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

• Blinking blue: Searching for GPS satellites
• Solid blue: Successfully connected to GPS satellites with good signal
• Off/Dark: Device is in standby mode or has lost GPS signal

Green LED (Cellular Connection)

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

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

Normal Operation Patterns

Optimal Performance

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

• Your tracker has both GPS location and cellular connectivity
• Location updates are being sent to your Hapn account normally

Acquiring Signal

What you might see: Blue LED blinking + Green LED slow blinking

• GPS is connecting to satellites (normal in new locations)
• Cellular connection is good
• Action: Wait 2-5 minutes for GPS to connect

Connection Issues

What you might see: Blue LED solid/blinking + Green LED rapid blinking

• GPS may be working but cellular connection is poor
• Action: Drive to an area with better cellular coverage

Troubleshooting Light Issues

No Lights At All

Possible causes:

• Device not properly inserted in OBD port
• OBD port not providing power
• Vehicle ignition not turned on

Solutions:

1. Remove and reinsert the tracker firmly into the OBD port
2. Try rotating the tracker if it doesn't fit easily one way
3. Turn on your vehicle's ignition
4. Consult your vehicle's owner manual for OBD port information

Blue Light Won't Turn Solid

Possible causes:

• Obstructed GPS signal (underground, covered parking)
• Poor GPS reception area

Solutions:

1. Drive to an open outdoor area
2. Wait 5-10 minutes for GPS acquisition
3. Check if tracker is blocked by metal dashboard components

Green Light Blinks Rapidly for Extended Time

Possible causes:

• Poor cellular coverage
• Network connectivity issues

Solutions:

1. Drive to an area with better cellular signal
2. Wait 10-15 minutes for connection to establish
3. Try restarting by unplugging and reinserting the tracker
