5.1 Introduction
There are two Front Panel LEDs that indicate the status of the Contribution Receiver. These
are used to indicate abnormal performance of the unit.
5.2 Location of the Alarm and Lock LEDs
The red ALARM LED is used to indicate an equipment fault condition, for example a missing
or faulty input signal. It should be off during correct operation, although it may be lit briefly
during power-up.
The green LOCK LED is used to indicate that the equipment is locked to a transport stream
when lit, and indicates correct conditions and correct system functioning.

5.3 ALARM LED
The Contribution Receiver supports a summary alarm signal that is active when one or more
of the individual monitored alarm conditions are active. It allows masking of unwanted alarm
conditions so that they do not contribute to the summary alarm. Configuration of alarms is via
the Front Panel and remote control interfaces. The state of the summary alarm is reflected by
the ALARM LED on the front panel where red represents an alarm, and off represents no
alarm.
This LED provides a high-level indication of an alarm within the unit. The alarm list depends
on the unit model. The unit continuously monitors for the following alarm conditions during
normal operation: (if not masked, see Menu 6, Annex C, Menus):
• No transport stream
• Video not running
• Audio 1 not running
• Audio 2 not running
• Audio 3 not running
• Audio 4 not running
• Unit temperature
