LEDS: ALARM and WARNING OFF
If no alarms or warnings are shown, suspect a bad connection or mis-program-
ming of the U4650. (Typically, if the U4650 is unable to present services, it
should be showing Alarms or Warnings. However, the unit can be set not to
indicate, even though this is not recommended.) If audio or video are missing,
check at the front-panel monitor jacks. If okay on the front monitors, check the
signal connections from the rear of the unit to the destination. If an audio is
missing from the rear-panel outputs and cannot be detected at the front-panel
monitors, check that a valid audio stream is selected for that port and that the
network provider has supplied non-quiet programming on that audio.
4.3 Alarms and Warnings
The alarm and warning system is intended to alert the local user of a present or
impending loss of services. The tables below list many (but not all) of the pos-
sible alarm and warning messages that the U4650 may display. For problems
you cannot resolve on your own, please contact Wegener Customer Service
(see Chapter 5), and be prepared to describe your signal setup, U4650 configu-
ration, and any displayed alarm and warning messages.
Alarms
An alarm is asserted when the unit is unable (or presumed to be unable) to per-
form a required function or deliver required services.
Warnings
A warning is asserted when an alarm condition is imminent or to indicate other
conditions requiring user attention.
