Figure 2.3: Remote AUI Login Menu

Describing the AUI layout

The AUI begins with the 

Home

 page and all further navigation will start from this screen                     

(see 

Figure 2.4 on page 2-11

).

Any user can view the AUI pages on the front panel of the transmitter, regardless of the login 

status; however, only users with the appropriate permission level can access functions that alter 

the transmitter control settings. 

Users can access the login menu by pressing the 

Change User

 button located in the bottom 

banner of the AUI  when logged in locally. It should be noted that this same button is shown 

as 

Log Out

 

if viewing the AUI remotely (see 

Figure 2.4 on page 2-11

).
