When Connected to Power

When the device is plugged into power the LEDs will initially go through a quick sequence of red and green, then blue, then red and green, alternating green and red, a blue flash, and finally, a solid LED state should appear.  This LED display will indicate the battery level.  This is also achieved during a battery status check which is achieved by holding down the button for 5 seconds until the LED turns off.


When unplugging from power, the LEDs will perform a sequence as well that alternates quickly between green, red, and blue.  This is normal before turning off.

During Operation

* S Series: A Blue Light blinking during operation indicates IMU is not calibrated.

* W Series: A solid Blue Light while recording indicates that the GPS is on but has not yet secured a lock with the satellites.

* W Series: A rapid blinking Blue Light while recording indicates the GPS is on and has secured an accurate lock with the satellites

After Recording is Finished | W Series

Error Codes

When initially connected to power the device will perform a self-check test.  If something fails, the red LED will methodically and slowly blink.  This is an indicator that something is wrong and the unit may be permanently damaged.  For more information, visit the error codes article.
