LED behavior
The device exhibits different LED behaviors depending on the shipment status, alarm status, and the button pressed in the SCM system.
The device only acknowledges a button press after the button has been held for 3-12 seconds. This is to prevent accidental button pressing during a shipment.
Tip
We recommend pushing the button for 5-8 seconds.
The action is invalid (i.e., it does not get registered in the SCM system) if you keep pressing the start button or the stop button for more than 12 seconds (more than 20 seconds on firmware 2.5.0 and higher) or less than 3 seconds.
