button is red, one or more alarms of severity level 10 is being reported; the transmitter is in an

none of severity level 10) is being reported, but the transmitter is still ‘on-air’, possibly at
reduced power. When the Status button is green, the transmitter is operating normally. In this
case, there are no alarms being reported, or there is one or more alarms of severity level 1 (but
none of severity level 5 or 10). This page is also available through the Menu page.

status from the front panel display, see Enabling Remote Control on page 2-96.
