status messages
8.3.0.1 Built-In Test Equipment
The ADU and the ACU have a Built-In Test Equipment (BITE)
function in order to make fault diagnostics easy during service and
installation. The BITE test is performed during:
• Power On Self Test (POST), which is automatically performed each
time the system is powered on.
• Person Activated Self Test (PAST), which is initiated by starting a
self test in the web interface
HELPDESK > Self test
.
For details on error messages after a POST or a self test see
8.3.0.2 Means of signalling
The SAILOR 100 Satellite TV provides various methods for signalling
the system status.
LEDs
on the front panel of the ACU are used to
signal:
• Power on/off
• TV Ready
• Fail/Pass
The built-in web interface of the ACU shows any events (BITE error
codes) with a short message describing each error. This is also
displayed in the ACU.
In an error situation, one of the following system status messages
may be shown:
• ACU POST error
• ADU POST error
• SAFE MODE (plus information about the specific error, see
