The device is configured to join the network using Over the Air Activation (OTAA). It starts a join request session (JRx) and shows the frequency, SF and power used during this session. When the product receives a Join Accept (JA) from the network, the information is displayed on the screen and the product switch to the main screen (uplink/downlink).
The requests are identified with "JR" followed with a number showing the number of requests done. The frequency used for the request is shown after this information.

When the GPS signal has not yet been “fixed”, no information on latitude or longitude will be displayed on the screen and the information icon will indicate that GPS has not been synchronized yet.
This menu can be accessed by briefly pressing the pushbutton 2 after the GPS menu. It allows to evaluate the quality of the radio connection between the device and the network.
The screen will display:
The number of frames sent (UL COUNT), including repetitions
The number of frames received (DL COUNT)
The Packet Error Rate (PER), as a percentage
The PER measurement is calculated by comparing the number of frames transmitted to the number of frames received: PER (%) = 100 - (( DL_COUNT / UL_COUNT) * 100).
This menu can be accessed by briefly pressing the pushbutton 2 after the PER menu. It allows to view a downlink frame sent by the network. This frame is displayed in ASCII characters. The non-printable characters are replaced by a point.
