You can use the optional LOI to configure the device.
The LOI is a two-button design with internal and external/rear
buttons. On a polished stainless steel housing, buttons are located
internally both on the display and terminal side of the transmitter.
On an aluminum housing, buttons are located on the display and
externally underneath the top metal tag.
To activate the LOI, push any button. LOI button functionality is
shown on the bottom corners of the display. See
