What do the different colors of GPS device LED lights mean?

Quick answer: 

When charging the battery:

- The red light stays on when the battery is charging
- Red light flashes every 3 seconds -> Charging fault/malfunction
- Green light stays on when the battery is fully charged (charger can be removed)

At startup when the device is switched on:

- The green LED light stays on for 10 seconds once the device is switched on
- Then the device alternates between green and red LED light (e.g. when the device is searching for satellites)

When the device is ready for use:

- Only green light flashes every 1sec (the device has found satellites and is ready for use)
- Test that you get position updates via Tracker Live -service before unleashing the dog

When the battery charge is too low:

- Only the red LED flashes every 3 seconds -> connect the device to the charger

How the lights indicate a possible fault/malfunction:

- Only red LED flashes every 3sec - - Charging malfunction
- Only red Led flashes every 0.2sec -> SIM card error or SIM card reading problem
- A sequence of following lights: Green + 1 red -> GPS not available
- A sequence of following lights: Green + 2 red -> GSM not available
- A sequence of following lights: Green + 3 red -> GPS+GSM, neither is available

If it seems that you're unable to switch off the device, you may have turned the power switch too quickly:

1. Turn the power switch "half a turn" in counterclockwise (wait a couple of seconds)
2. Turn the power switch another "half a turn" in counterclockwise (wait a couple of seconds)
3. Then turn the power switch the last "half a turn" in counterclockwise, to complete the switch off

The LED lights may flash for 5-15 seconds after the device is switched off

In those situations where the GPS device is logged in to the Tracker Live service (even momentarily) despite the problem, i.e. it is possible to get some connection to this GPS device, then Tracker's technical support can also help, so call or send a Support request 

If the GPS device does not seem to respond to anything anymore e.g. 

  • Restarting the device fails when you -> open "Settings" menu for the device -> tap 3dots icon at the upper right corner -> restart the device
  • The device doesn't get connect to Tracker Live -service (not even when fully charged, with good network coverage and not even when waiting a good few mins between restarts)
  • You get an error message when trying to call to the phone number that the device is using

Then Tracker's techsupport will not be able to help out. But first, before sending the Artemis over to Service/Maintenance, contact Tracker Oulunsalo Service by sending a Service request (on web form, select: Message subject -> Service)

I want to send my GPS device to service / maintance, how do I proceed?
