Quick Start Guide
Verifying configuration with LOI
The optional LOI can be used for commissioning the device. The LOI is a
two-button design with internal and external buttons. The internal buttons are
located on the display of the transmitter, while the external buttons are located
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 Table 4 and
Figure 9 for button operation and menu information.
