19.2	126	TrackerD is configured as LoRaWAN OTAA Class A GPS tracker by default. It has OTAA keys to join LoRaWAN network. To connect a LoRaWAN network, user need to input the OTAA keys in the LoRaWAN IoT server and push reset button of TrackerD (next to USB port). TrackerD will wake up and auto join the network via OTAA.

	396	User can push the RED button by more than 5 seconds to enter Alarm Mode.
	397
	398
	399	Once enter Alarm mode, the GREEN LED will flash 3 times, the buzzer will alarm for 5 seconds, then TrackerD will immediately send a packet without location info and then send a data packet with GPS positioning information. After that, the device will send 60 packets at 1-minute intervals. The Alarm flag in the payload will be set for the next 60 packets unless exit alert mode.
	400
	401
	402	Two ways to exit alarm mode:
	403
	404	* Server send a downlink command to exit.
	405	* User fast press the RED button 10 times.
	406
	407	When exit alarm mode, RED LED will light up for 5 seconds, indicating that the alarm mode is exited. And the alert flag will be set to false.
