Unity 4600 User’s Manual

Audio FP Monitor Selection Screen as default

For two minutes, or until ESC is pressed, the Level 2 Audio FP Monitor Selection screen is

the default if the unit features a front-panel audio monitor jack and the user plugs in a ¼”

stereo phone plug. Note that this is NOT usually a first-level screen, unlike other default

examples.

On the home screen, the (right-pointing arrow) field will quickly flash (a half-second ON

and a half-second OFF) to signal the user that the right arrow button is active for user

control. Pressing either the left or right arrow buttons will cause the Unity 4600 to display the

other top-level screens in succession. If there are current alarm and warning indications, the

text "See alarms" or "See Warnings" will appear before the arrow and pressing the right

arrow will display the applicable alarm or warning message(s).
