What Do the Lights Mean on the Asset Tracker?

This guide explains the meaning of the light indicators on your Asset Tracker device and their patterns during various operations.   

Light Indicator Definitions

• BLUE Light: Indicates GPS/satellite connectivity status
• GREEN Light: Indicates cellular connectivity status

Power-On Sequence

When activating your Asset Tracker from a powered-off state:

• Press and hold the face button - No lights appear for 3 seconds, then both lights illuminate together solid for a second. Release the button when you see any lights on.
• Satellite Connection - BLUE light flashes while searching for satellites; becomes solid momentarily when connected, then turns off
• Cellular Connection - GREEN light flashes rapidly while searching for cellular network; flashes slowly several times when connected, then turns off

Standard Operation

• During normal operation, the Asset Tracker displays no lights to conserve battery power
• Light indicators activate only when the face button is pressed to power on or SOS, or when the device is placed on a charging pad

SOS Function

After device activation, the face button serves as the SOS function:

• Press and hold the face button
• Both lights will illuminate solid for 3 seconds
• Both lights will then flash in unison once per second, indicating active SOS mode

Charging Indicator Lights

When using the wireless charging system for your Asset Tracker:

Charging Pad Indicators

• When first plugged in: The pad displays a flash of red, followed by a flash of green, then solid green
• Solid green light: Pad is powered and ready for use (no device on pad)
• Pulsing red light: Asset Tracker is placed on the pad
• Pulsing red light continues until the device is physically removed from the pad, even when fully charged

Asset Tracker Indicators During Charging

• While charging: Both blue and green lights flash in tandem (simultaneously) approximately once per second
• When fully charged: Both lights illuminate solid

When the Asset Tracker is removed from the charging pad, the pad light returns to solid green.

Important Information

• For new devices or those with fully depleted batteries (0%), the initial face button press activates the power-on sequence
• The SOS function becomes available only after the device is powered on
• The absence of lights during standard operation is normal and indicates proper device function
