SySTEM STATUS MESSAGES
This section applies to the panel mount Lynx NGT-9000. The system
status messages are seen on the screen either during start up or
when the System Test button is pressed. The typical meanings of the
messages are detailed in the bullets below.
A “Fail” message is caused by something internal to the Lynx NGT-
9000.
An “External Fail” message is caused by a problem with the external
equipment input signals. The unit continues to attempt to acquire
the signal without rebooting. These messages will automatically
clear once communications has been restored to the external
equipment.
A “Degraded” message indicates a function has limited capability
due to an internal failure.
An “External Degraded” message indicates a function has limited
capability due to an external failure.
A “Coverage” or “No Signal” message indicates that no signal is
being received from a ground station.
Attempt to clear fail or degraded messages by cycling power to the
unit.
The Continue button is active whenever a failure or degraded window
message is shown. It may be used to begin normal operation with
degraded performance.
The Lynx NGT-9000 continues to operate even if a failure is detected
during the System Test by providing any functionality unaffected by the
failures. Secondary faults are displayed as “Service Unit Soon” as part
of the message. (These faults do not directly impact the operation and
function of the Lynx NGT-9000, but are recorded in the maintenance
log).
Tap the MSG button located on the Transponder Application screen to
view fail messages during normal operation. The MSG button blinks
when new messages have been received and have not yet been
viewed. When all the faults are cleared the MSG button is removed
from the screen.
